The latest projector from Optoma, the HD66, is a compact, inexpensive 720p DLP home theater projector. Its 2500 lumens of brightness are perfect for games or sports, and its 4000:1 contrast ratio gives high-contrast images plenty of pop. Moreover, it is 3D Ready, which provides you with some insurance against the gathering storm of 3D that's just over the horizon. If you are not into 3D, don't worry--the HD66 is a great 2D home theater projector as well. The best part? This little powerhouse costs only $699, making it affordable to just about everyone.


Resolution. The HD66 is a bright little package, rated at 2500 lumens maximum. Now, the HD66 is marketed as a 720p projector, since that is the maximum resolution at which it can display 3D content. However, it has a 1280x800 DLP chip, so not only can it display native HD 720p, but it can also display computer signals in 1024x768 and 1280x800 without compression as well. It will display HD 1920x1080p/60 in compressed form. It cannot display 24p natively, but it is sometimes difficult to tell the difference between 60p and 24p even on native 1080p projectors.

Lumen output. Bright mode is the projector's brightest setting, as the name implies. As is typical of high lumen output modes, it is biased towards green, and color accuracy is not as good as in other modes. It is suitable for HD sports and video gaming in a room where you'd like to keep the lighting turned up. Using 720p content, the projector measured 1979 lumens. When using a 1280x800 signal from a laptop or other 16:10 source, it measured 2199 lumens, due to the use of the entire DLP chip.

If you want to watch film or video content in a light-controlled environment, you can use one of the HD66's other image modes. These modes can improve color fidelity and contrast while cutting lumen output, which will help to reduce the incidence of headaches in your audience due to a too-bright picture. Movie mode measured 1410 lumens with the lamp on high, which is still awfully bright for movies in a dark room. Low lamp mode reduces this and all other image modes by 13%, which brings Movie mode to 1227 lumens.

For best results, though, you will want to change the default settings of the HD66 rather significantly. On our test unit, we lowered brightness from the default of 50 to 33, raised contrast from 50 to 67, increased color saturation to 68 and fine-tuned the color temperature settings. We also disabled BrilliantColor completely. The result is a higher-contrast picture with deeper color saturation that looks better than any of the factory default modes. With these adjustments, the HD66 delivered around 670 lumens of brightness, which is still brighter than the average video-optimized home theater projector. Low lamp drops this operating mode to 582 lumens.

Contrast. The HD66's 4000:1 contrast ratio doesn't sound like much. When we first began watching a movie in its factory preset modes, it was still disappointing. Blacks were not deep enough, appearing more gray than black, though shadow detail was good. But after calibration, the picture improved by leaps and bounds. You can lower brightness on the HD66 significantly from factory presets without losing shadow detail, and the result is a deeper black level, well-defined shadow detail, and a more three-dimensional image.

Color. In its preset calibrations, color on the HD66 is only fair. In the brighter modes, such as Presentation and Bright, colors lack proper saturation and accuracy is as normal for these modes. Movie mode is better, since the greenish bias is not present, but saturation still needs a boost. However, after some adjustments by the user, the HD66 has bright, vibrant, well-balanced color that is perfectly suitable for home theater use.

3D. The big story about the HD66 is not that it is another inexpensive 720p projector, but that it is a 720p 3D projector. The HD66 is capable of displaying 1280x720 content at 120 frames per second, which equates to 60 frames per second per eye. You will need a 3D signal source, such as a computer with a powerful graphics card, and one pair of active shutter glasses compatible with DLP Link for each viewer. Keep in mind that the fact that a projector is capable of showing 3D does not mean that it will be compatible with all 3D signal sources in the future. But if you are in the market for an inexpensive home theater projector and want to have the 3D experience, the HD66 will give you just that.


3D Brightness. No matter what projector you use, there is always a dramatic drop in lumen output when using 3D content. For example, the HD66 produces 1979 lumens in Bright mode. Once you turn on 3D mode, lumen output drops to 660. This is the maximum lumen output possible in 3D mode, since no matter what mode you are using, the HD66 ignores your settings after making the switch.

Then, one must factor in the glasses, which can reduce perceived brightness by 60% or more. That makes for a perceived brightness of well under 300 lumens. Things are not as grim as they sound, however, due to the way the glasses operate. Yes, the glasses do cut perceived light output significantly, but they don't solely affect the projected image. The combination of 3D mode and shutter glasses reduces black levels more so than than highlights, making for a higher-contrast picture. It also means that ambient light is reduced by 60%. So, while the picture does appear dimmer, it maintains the same relative brightness when compared to the room environment.

Pre-calibrated modes. The HD66 is a great home theater projector once it has been tuned up, but the picture controls absolutely need to be tweaked to get the best video image out of it. Since the projector is only $699, it won't make sense for most users to lay out an additional $300 for a professional calibration. But the simple adjustments noted previously will produce a dramatically better image than you get from the preset modes, which are optimized for brightness. That is fine for lights-on living room viewing, but not so much for ideal home theater.

Also note that in Movie mode, BrilliantColor defaults to full blast. BrilliantColor on this projector boosts highlights without affecting the rest of the image, which is a great feature for presentations and data display but less than ideal for home cinema. BrilliantColor should be turned off when trying to achieve the best video image for dark room viewing.

Image noise. The HD66 shows a level of image noise comparable to that of other low-cost home theater projectors such as the Optoma HD20 and Vivitek H1080FD. Noise is most visible in solid-colored areas of medium saturation, such as a cloudy sky. It shows up primarily in video or film content, while data images appear more stable.

Placement flexibility. The HD66 has a 1.1x manual zoom lens and no lens shift, which is typical of inexpensive DLP home theater projectors. For example, you can fill a 120" screen with a 16:9 image from 13' 6" to 14' 10", depending on the position of the zoom lens. The fixed throw angle means that the bottom edge of this same image will appear almost 11" above the lens' centerline, which is an offset of about 22%. As a result, the HD66 needs to be positioned carefully to fill a given screen size, either on a low table or using a ceiling mount. Placing it on a low table is less labor-intensive and less costly since you don't incur the cost of a ceiling mount and longer run cables.

Signal loss with long cables. We have a set of long HDMI cables which we use to test signal transmission and reception. When using a 50' long cable, the HD66 occasionally "sputtered" as it lost and reacquired the video signal. This happened very quickly, so it appeared to be nothing more than a flash of static, but it was distracting and completely unpredictable. With 25' cables we had no problem. So if you plan on installing the HD66 using a very long run of cable, test it first before running that long cable through walls and ceiling. You may want to use two shorter cables with a signal repeater between the two. This will mitigate signal loss over distance and ensure that the image does not drop out.

Remote. The HD66's remote seems like it came straight from a business projector. It is small and crowded, with most of the clutter coming from the two directional pads. One of these pads is for mouse control, which most home theater users will find useless. The second directional pad is for menu navigation, and it is not immediately obvious which one is which. Below that are buttons for keystone correction, volume control of the onboard two-watt speaker, and then a whole mess of buttons in no particular order, numbered one through nine. These buttons control Brightness (though there is no corresponding button for Contrast), bring up the Menu, control the digital zoom, select HDMI as a source, freeze the image on screen, enable A/V mute, select S-Video, VGA, or composite. As you can probably tell, the layout of the remote is a little confusing. A number of times, we found ourselves accidentally switching sources or muting the picture when we meant to bring up the menu. While the HD66 is an inexpensive projector, the remote was still a disappointment.


The Optoma HD66 is a small, powerful, versatile home theater projector that's great for movies, video games, or HD sports. Its pre-calibrated picture modes optimize brightness, which is great for use in high ambient light but not ideal for cinema. A little fine-tuning of the picture controls gets you a dynamic, vibrant picture that's perfect for movies. 720p 3D support adds a bit of future-proofing and allows for the use of 3D PC games, if you have a computer powerful enough to handle them. All in all, the HD66 offers an outstanding value for those on a budget who want a bright home theater projector that is great for movies, video games, and for additional types of computer-based projection as well.

This is great news. Apparently you can create a "3D ready" projector with virtually no new engineering. This probably means that all the manufacturers will take one of their bright, imexpensive business projectors and turn it into a 3D machine very soon.

As I understand it, Brilliant Color technology can be implimented so as to optimize any one of several different characteristics. This early Optoma machine still is optimized for PowerPoint presentations. The next generation machines presumably will be adjusted to optimize for 3D movies. 3D projectors seem to be very easy to make. Good news.

How does this projector compare to the HD65 for watching movies? Physicially it looks a lot like the HD65!
Dave Posted Feb 8, 2010 10:37 AM PST
I saw this projector on NewEgg.com for $749.99 and thought it looked like a great deal. After reading your really great review, I think it's time I bought one. :).

Thank you for your well put together review, it really helped me make an informed choice.

How does this compare to the aforementioned HD20 and H1080FD projectors in 1080p mode?
IvanK Posted Feb 22, 2010 7:45 AM PST
I wonder how this projector compares to Epson Home Cinema 705HD? They are at the same price range and both are very bright at 2500 lumens, but Optoma has a higher contrast rating (which also isn't inflated by the use of the dynamic iris) - does that translate into a noticeably better viewing experience?
Rich Posted Feb 22, 2010 1:07 PM PST
Thank you for pointing out the reduced ambient light factor when discussing 3d! Everyone hears the "reduced light" issue so often it becomes completely ingrained in most people's minds, but very seldom is the reduction of ambient light mentioned. Of course the reduction still matters quite a bit, but it's not quite as critical as most think it is.
Dan Gould Posted Mar 25, 2010 10:31 PM PST
In the review article for the HD66 it was recommended to set the saturation level at 68. For some reason the setting does not hold and it goes back to 50% once i leave the menue. I was told by Optoma to return the projector as it must be defective. I was sent a new unit replacement and I still have the problem with the new repacement.. Am I doing something wrong? Has any one else had this problem? All the other settings work Fine. I would appreciate any help I can get. Thank you, Dan

On Amazon the same projector is available for about $650/- So get it from there.

I want to creat an exercise room and do not want to place anything on the floor to get in the way. I think using a projection set up is brilliant. I came up with the idea and my spouse says he can cheaply implement this with the VCR and DVD player projected onto a screen. I don't care whether it accesses a tv or not. But reading about this great reason to get all these great features tells me that we should spend more than $100 just for the projector alone. Is it difficult to go back and upgrade the projector to a better one; and are prices likely to drop as technology progresses? I am tired of waiting to exercise while he goes to the gym. Maybe someone wants to get rid of one or has some other suggestions! Thanks a million!
Moviefan Posted Apr 13, 2010 1:20 PM PST
Fantastic projector! I upgraded from an Optoma EP-757 DLP to the HD66 and it's worlds better. I bought a HDMI auto switcher and now have easy access to HD cable, Blu-Ray, HD XBOX360, and PC. The image is gorgeous. The throw distance is even shorter than the EP. I only have good things to say about it. Okay...the remote is cluttered and confusing, otherwise I'm super happy. The unit can go very bright for when we have all the lights on; and then with the settings in the review, it gives a great movie picture in near-dark. The xbox360 in HD really blows me away. Got it for $645 (shipping included) from Erie Computing. For this price range, I give it 5 stars.

You can buy this projector on buydig.com for $633 with no tax with a $16 shipping fee. Just bought it for my backyard 9' x 16' screen.
Ron G Posted May 3, 2010 11:31 AM PST
Costco.ca sells a rebadged model of the HD66. The unit in my opinion rivals the image of my plasma television and is on a screen 5' by 8'. Very happy with the performance of this projector and the price under $700. I constructed my own screen out of MDF and finished it with Behr UPW flat enamel tinted to silver screen with 25% Behr pearlescence added. No color shift issues detected.

i was wondering if this will work with a ps3? i mean to view the 3d content... since the ps3 has been updated so it can play 3d movies if you have a 3d tv... would the ps3 also work with this projector to make 3d movies??
Gord Posted Jun 24, 2010 4:23 AM PST
Thank you so much for your great review! We bought an HD66 yesterday and without your help to adjust the picture settings, we would have had to take it back. What a difference!! Question: Is there a menu item for colour saturation? We were unable to make that adjustment, and wonder if it is a result of the adjustments to brightness and contrast, or if we are still missing something? Hope to hear back. Gord from Markham
skur2 Posted Jul 3, 2010 8:09 AM PST
i bought this projector a couple days ago and it is aweseome! i dont have it mounted to the roof and its not directly in line but using the digital stuff i corrected the view cool stuff im thinking of getting a roof mount though or a little shelf or something though lol..

image quality is better then i expected

brightness had to be turned down below 50% even in daylight its like an atom bomb going off in the room lol i use just a painting canvas as my screen i might paint it with that stuff that simulates it.. i dunno this is good for now though

it does heat up more then i expected though!

thats one of the cons in my opinion is that the cool down period is to fast...

solder joints ussually break when the heat up and cool to fast, so i dunnop iof that will be a problem down the line,...

overall 8/10

good price!

ive used it with my PS3, PC, and DVD

my pc has a nvidia Gtx 470 video card so it can display 3D without those expensive glasses just red and cyan which u can make yourself with markers lol

anyways 3d is amazing with just that! not a huge drop in brightness at all

anyways thougt id review it! :P
Gan Posted Jul 8, 2010 2:32 AM PST
In my country there isn't any HD66 yet, and the old HD65 still considerably more expensive than the Dell 1610HD. From the spec, 1610HD looks very similar to Optoma HD66, anyone tested this for home theatre usage?

I'd interested to get my first projector and it seems the Dell 1610HD is my best bet considering the price and the 2 years warranty Dell provides; any comment on that?

I'm looking at buying one of these, but have read that it has a safety feature, which requires the lens cap to be repaced after turning off and before turning back on, otherwise it wont turn on. (not very handy when ceiling mounted) Can anyone confirm or deny this? Can I leave the lens cap off, all the time?

I just received my Optoma HD66 and got it set up. I ordered it from Costco for $699 which included a 2nd year warranty, free shipping, and a free optoma high-end 92" screen mail in coupon (also shipped free). Way worth the extra little cash (unfortunately sold out now I think).

I was looking for a cheap and portable fix for college. So I went with the HD66 based on the specs and reviews: I must say this was an excellent buy. Even projecting on a plain tan painted wall it is an excellent picture (especially with a blu ray input).

Like everyone else said out of the box the default settings were ok but not great. I did some research online and tweaked some settings and it looks fantastic!

I was a little weary about buying old technology (720p) but was happily proven wrong. It looks better than my family's 73" Mitsubishi diamond series full HD DLP TV with the same blu ray input (and larger to boot for half the price).

I haven’t hooked it up to my computer yet to play Starcraft 2 in 3D, but when I get glasses I will review that as well.

This projector should satisfy everyone but the most descriminating taste. Espcially for this price tag value.

eeks only 3000 hours Posted Sep 12, 2010 10:39 PM PST
3000/24=125 days of leaving tv on all the time, like I do, always the problems with these projectors. Its why noone bought them at 10k and noone will tell they only a few hundred either.
Okey Posted Sep 25, 2010 7:14 AM PST
"3000/24=125 days of leaving tv on all the time, like I do, always the problems with these projectors. Its why noone bought them at 10k and noone will tell they only a few hundred either."

Always the problems with these projectors. :D Geez! With Optoma HD66 you would be mostly using it in eco mode. So that would be 4000h of usage. You do leave your TV on all day, every day? Not much sense there but okay.

If you think about regular Joes leaving their televisions on, it might be something like 10h / 3 days a week. VERY HEAVY usage by any standards. The lamp would last over 2,5 years. This projector sells for $650, replacement bulbs are priced $150.

Is this projector compatible with Blue Ray because I just brought an optima and found out that I cant use it with my new blue ray player and sound system
Warren Posted Oct 20, 2010 12:37 AM PST
All existing 3D compatible projectors, and almost all 3D computer monitors and all current 3D plasma/lcd tv's display 120 frames per second, 60 for each eye, controlled by shutterglasses. The huge difference is how the 3D is transmitted. The 3D Projectors and 3D computer monitors accept a 120 Hz signal from a computer to transmit 3D. Every other frame is for the left eye, the other frame for the right, just like it is displayed. 3D Blu-ray players/PS3, on the other hand, transmit a funky frame packed 3D so they can output both eyes frames in one 60 Hz signal. Processing inside the tv turns that into 120 frames per second ouput for the screen. nVidia 3D vision on the computer will play video games with 120Hz output. The newest PowerDVD will play 3D blu-ray movies on the computer at 120Hz for this projector. Obviously it would be nice to plug your 3D blu-ray player/PS3 directly into the projector, but as the signals are comletely different this won't work. The solution, which should be available early next year, is the Optoma 3D-XL converter box. It will take the 60Hz frame packed signal and turn it into 120Hz frame sequential for these current 720P 3D ready projectors. Future projectors from LG and Sony will accept the frame packed 60Hz 3D signal (and cost tons of money, but at least be 1080P.) Sorry for the long anwser. Short anwser is no, you can't plug your ps3 into this for 3D.
projectpro Posted Oct 24, 2010 11:40 AM PST
I currently have my HD66 and PS3 hooked up and its running 3D in the games np with the Optoma DLP link glasses, I haven't tried blueray yet though. The effect looks great in the 16:9 aspect.

So far it works well for the 2D conversion games, I don't know if PS3 has any "3D vision ready" or whatever titles yet.

SIDE: The nvidia glasses/emitter for the PC allows you to control the depth of the 3D, does anyone know if you can adjust that with the Optoma DLP glasses?
MichProjector Posted Nov 13, 2010 4:03 AM PST
On my last Optoma (716) I built a custom cable to go from the player (component) to the projector (rs232). I thought I was going to have to do this again (custom cable - component to HDMI) but find that the HD66 comes with a component/HDMI cable. So (finally the question)....is there any advantage in using the cable supplied by Optoma (HDMI/component) over my component/RS232? Thanks!
Perry Seto Posted Jan 8, 2011 2:32 PM PST
I am having great difficulty getting the HD66 to lock onto the HDMI line as it continues to cycle through all the input connections. I have set the OSD to sync to just the HDMI line but of no help! I am using a 4M HDMI 1.4a solid core Ultralink cable and have had the video card of an Onkyo AVR set to pass through and 1080p. I have tried many settings such as 720p as the standard as well! It continues to say no source found! Locks onto composite line instantaneously! Is this possibly a bad vard in the projector? Desperately need advice! MAy have to send it back!
Dennis Posted Jan 14, 2011 4:27 PM PST
As reported in the projector central review of H66:

3D Brightness " No matter what projector you use, there is always a dramatic drop in lumen output when using 3D content. For example, the HD66 produces 1979 lumens in Bright mode. Once you turn on 3D mode, lumen output drops to 660. This is the maximum lumen output possible in 3D mode, since no matter what mode you are using, the HD66 ignores your settings after making the switch."

Why is there this large drop to 660 lumen (from 1979 lumens) when 3D mode is selected? Is this reduction in lumen different in each of the modes (Bright, etc.)? Is the lumen reduction always the same percentage of the lumen before 3D mode is selected?
joe Posted Jan 18, 2011 10:48 AM PST

Does anybody know if we can connect a 3d blue ray to the HD66 but not using the 3d feature, just to watch normal 1080p form blue ray? Joe

RE: 3D Movie 1280x720@120hz Radeon HD 6870, optoma HD66 DLP Projector, 3dtv wired shutter glasses Anyone please help My config is : Radeon HD 6870, optoma HD66 DLP Projector, 3dtv wired shutter glasses with dongle, 3d half SBS mkv movies(eg Space Station 3D 1080p SBS x264-superstoreman.mkv)( i core2duo 2.2ghz, MB dg31pr, Mem 2Gb, win xp, Catalyst driver 11.2, stereoscopic player demo ver) I can watch 3d movies without any flaws in 800x600@120hz through vga cable. But there is no 1280x720@120hz to be selected. Only the highest config in 120hz is 1024x768, but stereoscopic player and shutter glass are not working together in this mode. ( I tried pulling DVI pins, overriding EDDID, + installing .inf files without success) This is how I have to watch my 3d half SBS movies in 720p@120hz through hdmi cable! 1. I have to attach an old crt monitor(VS 225pf) through vga cable > dongle > DVI – VGA adaptor > DVI-I socket in 6870 2.

Activate E-D.exe> pageflip> shutter glasses ON( now shutter glass will work at 120Hz) 6. Now I can start stereoscopic player & watch 3d movies ( sometimes I saw brown tinge . It may be due to slight lag/ ? refresh synchronization between CRT and optoma)

**Note that I don’t have to switch on crt for activating shutter glass, but all program will open in crt except full screen movie!it will open nicely in optoma!

Now could anyone advice me, how to bypass all this and watch 3D movies?

Hi, Comment for projectpro. You said you have the Optoma HD66 connected with a PS3 playing 3D games? I have the HD66 and PS3, last firmware update and I cannot make the PS3 to alow the 3D option. What was your set up? I do not have any glasses yet, just don't want to spend more money if it won't work. Any comments? thanks.
Jason James Posted Jul 20, 2011 5:57 PM PST
I just recently purchased this projector, a 3D Blu ray player, and glasses. What they dont tell you is that you need an optima converter as well (About $350) believe me....IT IS WORTH IT! After setting everything up (under $1000) I was able to watch cable 3D Tv as well as Despicable Me in 3D which was movie theater quality. Absolutely AMAZING!
justin Posted Aug 8, 2011 7:27 AM PST
I got the HD66. Pretty nice. I could use a little better quality out of the XBOX, but I suppose there are other variables that I didn't know about when installing the thing. i love the screen setup that I have though. It is in an apartment so I will have another go with the projector the next place I live in. Maybe a house.

Hi, i bought it-hd66, but cannot run 3d movies on it, i hooked (by HDMI cable) it with panasonic SC-BTT370-blu-ray 3D player, with 3D movie on it and however i changed the source settings on the player, the projector 3D function never will activates. but plaer plays on 3D. help me what i should do, to watch 3d movies on Optoma hd66???
saiful Posted Sep 15, 2011 3:04 AM PST
baagii, unfortunately optoma HD66/67 will not display 3D directly from a bluray player, PS3 or Xbox, you will need a 3d converter (optoma 3d-xl or viewsonic VP-3D1) to run 3D in this projector when using a 3D bluray.
Baagii Posted Sep 22, 2011 2:07 AM PST
Saiful, thank you very much, i will find a convertor. another question what is a difference between cheep HDMI cables and expencive golden cables? do i need to use those expencive ones to watch 3D movies?
saiful Posted Sep 26, 2011 4:54 AM PST
no you dont need the expensive HDMI cables, make sure you have at least one HDMI 1.4 cable to connect your 3d player and the 3d converter. i always use the regular cheaper HDMI cables and works for me.

Waiting on reply from optima if they can help. Only a one year warranty :( Expensive one year cost of ownership But was great while it lasted.

Bought the unit, Nov 2010. Worked great till Mar 2011. Sent back for repair, Mar 2011. Worked great till, Sep 2011. Sent back for repair, Sep 2011. Optoma repair dosen't fill out the RMA tracking info, as they should. Have e-mailed them several times. Seems they are waiting on a replacement color wheel. It is now Nov 2011, and they are still holding my projector for repairs. Not very dependable.

i brought HD66 few months ago and never tested 3D effects. I have Sony 3D blu-ray player and connected to HD66. Now i want to watch 3D movies, so what are the other equiments required to watch 3D movies.
Chris Diton Posted Dec 25, 2011 6:26 PM PST
Hi, I am having issues getting my HD66 projector to connect to a PS3 in a resolution other than 480p. I have been on the customer support line for Sony for hours trying to figure out the issue without luck. Any ideas?

Also, I can't find where to change the color saturation levels, please advise.
joel Posted Dec 27, 2011 6:10 AM PST
you need to lower hdmi output to 720p or auto load the disc but its hard when you see nothing during loading or when you start your ps3
Nicolas Posted Jan 8, 2012 7:51 PM PST
Hello experts.

PLease give me a COMPLETE calibration for the hd 66 for the best pictures for films. I have it on hdmi

Thanks in advance.
harles Posted Jan 15, 2012 9:24 PM PST
Joel what do u mean set to 720? I am having the same issue as Chris and I can't get the ps3 and hd66 to play 720 even with audio set to optical. Chris how did you fix this issue??

Thx in advance!
Marie Posted Feb 3, 2012 10:37 AM PST
Hello! Thanks a lot for your review!

I have bought Optoma HD66, but it arrived only with composit cable. I want to connect it to my laptop. Which cable should I bye?

Thanks a lot in advance!

I am posting this as information only. I recently purchased a Philips DVP3460 1080p HD Progressive scan up converting DVD player which replaced my old Philips DVD player. After plugging it in, it also Cycled through all the Sources, bypassing HDMI. I had the HDMI cable plugged into this projector and it seemed to try to connect it, however it eventually failed and would say "no sources Found".

I tried replacing the DVD player, however the same problems occurred. I know the HDMI cable worked since my old DVD player still functioned on it.

After a long search, I found that Downgrading my Firmware on my DVD player from 6.6 to 5.9 (http://www.p4c.philips.com/cgi-bin/dcbint/cpindex.pl?slg=en&scy=us&ctn=DVP3560/F7 the only firmware avaiable for Download) resolve this issue.

I called Philips to tell them this information. They responded with that It's not Philips fault it didn't work, and instead I should have Upgraded the Firmware on Optoma's Website.

Either way, I'm glad this is resolved. Hopefully this will help any of you looking to figure out why Optoma HD66 was cycling past the Source you intended for it.

Beware. I had this projector for just over a year and then pixels started dying. It is now totally unwatchable - a complete snowstorm. I'm currently looking round for a new projector.
Marlon Moyer Posted Mar 10, 2012 1:53 PM PST
Like Richard, my projector is just about 1.5 years old with < 500 hours on the bulb. I currently have around 130 dead pixels on my screen with new ones appearing almost everytime you turn it on.

I've also tried to contact Optoma about without any response :(
Eduardo Posted Mar 16, 2012 8:44 PM PST
I just bought a proyector optoma HD 66 in the proyection I have some vertical lines I start first random but actually the lines are continous. someone could gime me any orientation
KathyG Posted Apr 10, 2012 8:07 AM PST
After being very pleased with this projector for 12 months we started to see white and black dots appearing in the bottom left corner. Each day it was like a disease, spreading now covering half of the screen. I did research on the internet and found many posts with owners complaining of the same issue. (One is posted here) I believe it will be more to repair than what I paid for it. I have not even changed the bulb yet! Last time I will buy an Optoma.
Rimon Shalash Posted Apr 19, 2012 7:13 PM PST
I bought HD66 projector from Amazon, but when I'm connecting it to HD cord the sound is not working..!? I have to play the saound through the laptop..!!! can someone help me !! does that mean, I have to reship it back to Amazon
Grady Posted Apr 27, 2012 9:35 AM PST
Buy some computer speakers(Not USB) and plug them into the 'sound out' place on the back of the projector .
joe Posted Jun 14, 2012 10:45 AM PST
me and my girl just got the hd 66 projector....it was havivng problems cycling through outputs tried a new hdmi and that stopped, now it totally lost all sound, we've had it for 4 days now...concidering just returning it or hooking up external speakers....
E. Elias Posted Jul 16, 2012 8:06 PM PST
I owned and HD66 and just got the optama 3d-Xl to watch 3d movies. My whole system is set up using an Onkyo R607 for a full HT experience (great 7.1 system!!). So far the projector has been great (using a 109 inch screen). However I have not been able to set up the 3D. I guess the main problem has to do with the fact that the AV does not support 3d video (it only works as 1.3 hdmi). I tried to connect the converter directly to my sony blue ray but did not work either. Ideally I would like to use the AV. Is there anyway to by pass the receiver? Does anybody have a similar set up? Any comments or ideas are mostly apprecited
John Raines Posted Jul 20, 2012 4:54 PM PST
Good features, great price, poor reliability. The DLP engine in this model fails way too soon. Mine is only on its second lamp and the white spots (stuck pixel mirrors) are making the picture unwatchable. No more Optomas for me.
Alyson Pessoa Posted Jul 30, 2012 10:24 AM PST
I had the same issue with my Optoma model TH1020. I used it less than 3 times, I bought it on November 2011 and the same problem with vertical lines appeared in the screen. Now I contacted Optomal repair center and they want to charge me to repair de proyector. The warranty is one year but they don't tell you what is covered. I really disappointed with Optoma. First and last time I bought anything from Optoma.
Derek Posted Aug 10, 2012 7:49 PM PST
The HD66 puts out a nice image for the money but get an extended warranty if you can. At 11 months old mine started getting stuck pixels. Optoma repaired it under warranty (12 months) with very little hassle and all was well for another eight months or so. Now it's happening again. I have whole star constellations forming on my screen. I'm not sure if it's even worth paying to fix again vs. moving on to another projector.
Cinema Sam Posted Nov 8, 2012 8:16 PM PST
The stuck-mirror "snowstorm" has just started to ramp up on my unit. I agree that this is a problem being mentioned all over the internet. DEAR EDITOR: please do some due diligence and then update your review to show that these units are defective and go bad after 2 years (used or not -- apparently due to heat-conductive paste drying out or somesuch problem). Ti has a 5-year warranty on the DMD chip. I'm going to contact Optoma and Ti and see what they can do for me. - Sam
ILS Posted Dec 3, 2012 4:57 PM PST
I've had mine for over 2 years and it still works great. I've had some issues with it connecting to my HTPC via HDMI, but otherwise it was an excellent buy.
mgk Posted Dec 15, 2012 8:15 AM PST
Why is it that the professional reviewer at Projector Central makes a big deal out of the fact that even though the HD-66 has 2,500 lumens it automatically drops to 660 lumens with 3-D. But when the reviewer comes to the HD-33 that has only puhes 1,300 lumens the reviewer raves about the 3-D performance with no mention of the level of lumens it drops to. I quote from the review of the HD-66: “No matter what projector you use, there is always a dramatic drop in lumen output when using 3D content. For example, the HD66 produces 1,979 lumens in Bright mode. Once you turn on 3D mode, lumen output drops to 660. This is the maximum lumen output possible in 3D mode, since no matter what mode you are using, the HD66 ignores your settings after making the switch.” AM I to assume that the HD-33 operates at a higher level of lumens in 3-D because you can make adjustments in the brightness setting? I am trying to decide between purchasing a HD-33 or a HD-66. Any advice would be helpful to me and I am sure to others. Thanks.
Big Red Bert Posted Jan 22, 2013 1:23 PM PST
I've bought the HD66 in 2010, loved it price/quality, everything was awesome, hooked up to PS3 through HDMI, my PC through VGA-HDMI, Onkyo speaker receiver etc... Until the dead pixels started to spread, in 2012, checked everywhere, people had the same issue, but no clear answers. Bad reviews started to pop out allover the Internet. Verdict: Faulty DMD chip and my projector was of course out of warranty. Sent it back for repair to Optoma, they quoted almost the price I've originally paid for it. After harsh negotiations $200 would be the price to pay. then, couple of weeks ago, horrible loud grinding sounds, flickering image, still a bunch of hours on the light. New issue discovered: faulty color wheel!!!!! Called Optoma back, my unit is out of repair extended warranty and it will cost me big bucks again. This time I'm not sending it back, I'll try to fix it myself. I'm unfortunately glad to see that other people have the same issues. Optoma=Never again. Cheers.

I have a HD66 and it's out of warranty and I have the 3D-XL. I had a real nice set-up and now the chip has gone bad like everyone else's. Dots or snow, whatever you want to call it, the bottom line is now I need another projector long before I should have to go looking for one. The best way to look at this projector is that it's disposable after the warranty runs out. It also sucks that I'd already bought a bulb to replace the one in it if it went bad at my Superbowl party. If you buy one of these things just plan that it's junk at the end of the warranty. Some may argue it was junk to begin with since it only lasts a year.
Mirakaski Posted Mar 18, 2013 4:25 PM PST
Just want folks to know that Optoma is fixing this problem for free even if out of warranty. Give them a call. I just got mine back and it is good as new.
Ryan Posted Mar 19, 2013 10:51 AM PST
I had the white dots as well (6 of them) before my first bulb was even due to be changed and Optoma did a "one time" repair at no cost, just pay shipping both ways. Just call them and politely describe your problem and ask if they could do a "one time" repair. Fill out the repair form and attach a copy of the receipt of purchase. Ordered mine through Amazon so it was easily obtainable. FYI I had this repair done April 2012. Good luck!
Brian Posted Apr 5, 2013 7:36 AM PST
If I purchase a "Like New" model on Amazon, will Optima still do a on-time fix if it experiences the "white Dot" problem? Or does it have to be "New" or "Refurbished" for them to offer that? Anyone have experience with "Like New" versions of this projector from Amazon?
scaldera Posted Jun 14, 2013 10:30 PM PST
Yes they are still doing the one time fix for white dots. I just got mine back, 3 years old.
jeff Posted Aug 12, 2013 3:53 PM PST
the chip has a 3 year warranty on it, so if you get the white spots after 3 years (in my case 3 years 3 months) then you are out of luck. Repair cost $350...
Jitendra Posted Nov 15, 2013 10:01 PM PST
I have Optoma HD66 3d ready projector. I want to avoid buying 3d-xl converter to watch 3d movies. What configuration of PC i would require, if i want to watch 3d movies on it? My current PC does have nvidia geforce card. Is it sufficient? If my PC supports 12HZ frame rate, can i use this pc for 3d movie watching?
Bryan Posted Jan 6, 2014 12:35 PM PST
I'm curious to know whether a global warranty applies to this model if purchased in the UK. Mine's just over two years old and I'm getting white and black dots as indicated by many here. I'd be grateful for any information regarding their global warranty. Many thanks in advance.
Oliver Posted Jan 12, 2014 2:10 PM PST
Does anyone have a contact number/extension for Optoma? I called the one listed on their website to try and help troubleshoot and the guy was absolutely clueless about the product, very rude and not helpful at all. It seems others are having luck, so I was just wondering how you went about it?
Jeff Stein Posted Mar 24, 2014 12:09 PM PST
I have white spots diplayed on my projector screen, I have a HD66 Optoma projector. How can I get it fixed?
