Optoma HD33
1080p DLP 3D Home Theater Projector

Bill Livolsi, August 25, 2011

Limitations

The HD33 is a stellar product for the money, but it's not perfect. The notable limitations of the projector are as follows:

Placement flexibility. The HD33 only has a 1.2:1 lens and no lens shift. The lens has a fixed upward throw offset of 7%, so the bottom edge of the image will appear 7% of the image's height above the lens centerline. This mild angle is ideal for table mounting, while those with high ceilings might require a drop tube before the projector can be ceiling mounted properly (i.e. without using keystone adjustments). While there is nothing inherently wrong about a fixed lens or a short zoom range, many inexpensive projectors now offer longer zooms, and some even feature lens shift. This makes placement more difficult than it would otherwise be.

No gamut adjustments. Grayscale adjustment on the HD33 is a snap. Gamut, on the other hand, cannot be adjusted. To its credit, the HD33's default gamut is not completely off in left field, but there is some room for improvement. What color gamut tells us is how well the projector can interpret color data; when a signal calls for 100% red, the color it feeds back is defined in what is called a lookup table, or LUT. These LUTs can be adjusted to provide more accurate color, giving you the exact experience that the director had in mind. An inaccurate gamut does not mean that the projector necessarily looks bad, merely that it does not adhere to the standard.

Remote Control. The HD33 has no hardwired control panel, so all adjustments must be made through the remote. The remote is small and feels good in the hand, but everything goes to pot when you try to use it in a dark room. The backlight, a strong blue, is so bright that it wipes out the viewer's dark vision almost instantaneously. What's more, the buttons themselves are labeled with pictograms with printed words underneath. Unfortunately, it is almost impossible to read the printed words and the symbols don't make a lot of sense. Once you learn the layout, the remote becomes less of a concern, but it is annoying at first.

Light output. Cinema mode on the HD33 does not suffer for lack of light; in fact, it's one of the brightest Cinema modes we've seen in quite some time. However, when a projector claims to produce 1800 lumens and we then measure all of the preset modes at less than 1200, it is disappointing--especially when other projectors in this price range make the same claim but actually deliver.

I can tell you without a doubt that Epson support is the best I've ever dealt with, bar none. I bought an Epson 8100 and the bulb dimmed at about a year of 4 hours daily "living room" use. I contacted them and they sent a new bulb free, which they should have done (as their bulb life claims were higher). Though not by much if you figure in higher brightness usage. Another year goes by and another bulb wears out. I call them and they send me another bulb! All they asked me was hour used! A year out of warranty! I'll say nothing but good things about Epson any time I'm asked!

This is my last desperate attempt to learn more about their products ... Antero Eduardo Moran'm from Mexico, I'm about to buy the Optoma HD3300 (repaired or rebuilt) because Optoma SUPPLIERS for Mexico said the HD33 and HD3300 already been discontinued ... How real is that?, If so ... HD3300 could only buy the second hand ... Why no reviews of the HD3300 projector? I've come to think that went defective and wants optoma disappear from the planet ... Please help me not to do ...

Optoma? Going to get new projectors for games and 3d full hd and come to Mexico and when? Are the new ones are much better than dh33 or might even not separated much? ...

Thanks for your time and I look forward to your e mail responses (an apology for my bad English ... I am using the google translator

Initially I had the Epson Powerlite 5010. I had a lemon and tried to contact Epson for exchange. They gave me a lot of trouble because I bought from Ebay. They said it is considered a 3rd party and will not honor it even though it was brand new with warranty card. Epson customer relation sucks. I returned it and after reading the excellent review of this Optoma HD33 I decided to go with it.

Wow I was aesthetic with the quality for half the price of the Epson 5010. The DLP image seems sharper and very bright(standard) then the LCD's.The HD33 is quiter then Epson 5010 too. The best part is half the price of the Epson. This is the cheapest 3D in the market.

I was really blown away. my friends said movies projected seems better then movie theater's. I am so pleased. I would recommend the HD3300 as it comes with 3 years warranty including the bulb. This model only 1 year warranty but $300 cheaper. I highly recommend this. You will not regret.

Need Help .... Recently I bought Optoma HD33 3d projector with panasonic DMP-BDT220 3d bluray player. But I am facing a major issue, As my projector is not detecting the player when connecting through HDMI but it find it easily when connected through any other port ( RCA, component, S-video). To test projector I connected it my laptop, desktop, samsung galaxy s2, TV set top box through hdmi port and it worked fine for all. Then I connected the player to my LG HDTV (not 3d) through HDMI and that also worked without any problem.

Please let me know what is wrong between projector and the player and how to resolve it. Seems like some kind of handshake issue.

I've never seen this rainbow effect on my HD66 that people keep mentioning. Could it be because I only use in for watching movies in a theater room with little ambient light. P.S. Have loved it for many years, now looking for a PJ with horizontal keystone correction.

Joseph - no, passive glasses use an entirely different method to display 3D images than active devices like the HD33.

Think of it this way - passive devices play both 3D frames at the same time, and the glasses filter them so each of your eyes see only one of them. Active devices play one frame at a time (extremely quickly), and the glasses turn on and off quickly so each of your eyes only see the frame they need to.

I just got the HD33CA from Costco.ca. Great deal because it came with two glasses and is on sale at the moment with $250 off. Projector replaced the HD72 - It is beautiful! Picture is great - noise is low - 3D works once you figure it out. I highly recommend this projector. Costco also extends warranty to 2 years.

Hi ,

I am planning to go with the uk version of HD33( Puremotion4+10000:1 contrast). i want to go for 150" Diagonal 16:9 screen , I have the placement facilities for projector(floor or book shelf placing by trial and error), and screen ( ceiling mount), and have the distance to project. My question is if i watch movies with light off, and very little fugitive ambient light, will the 1800 Lumens for 150 screen be enough and how will be BRRIPS(BDRIPS)(4Gig)look(2D or 3D rips) if i connect a WDTV media player .. will the rips be mercilessly exposed on this big screen or with OPTOMA processing make up for it. Thanks..

I don't think making a passive 3d projector is much more expensive then active 3d. The LG projector is overkill. The added cost would come in purchasing a screen that preserves the polarization of the light. All the projector needs is a single polarizer. There are already third party devices on the market to convert projectors from active to passive 3d such as Tru3d. I already own an LG 55LW6500 LED panel and after watching passive 3d I will never go with active 3d again. Perhpas the price of the LG is more reflective of engineering overkill and a thin market than the actual cost to produce the projector.

Hi Bill!

I enjoy your informative reviews. My question: in your opinion, how much better (if at all) is the Sharp XV 17000 compared to the HD 33? I am only interested in 3D, as I will continue to use my Sharp XV 20000 for 2D. Bottom line: is the Sharp 17000 worth the extra money compared to the Optoma HD 33?

I appreciate your candid response.

I'm trying to decide on a screen to go with this projector. Size isn't really the issue as the room it will be in is 14'w x 30'l x 8'h, however I'm wondering about two things: 1) is there a difference between a so-called '3D Ready' screen vs one that doesn't have that in the product description and 2) 'Reference' vs a non-reference screen. Is the picture that much better for 2 or 3x the price? Any recommendations?

I wish there were some metric for rainbow effect and black levels. I had to return the BENQ6000W due to rainbows even though I seldom see them on my well-worn Infocus 4805SP. Probably the 2x brightness and increased constrast made them more visible. In any case I am considering the HD33 but I am afraid it too will have rainbows. It sounds like it has fewer but other web sites claims that they are still visible.

According to Optoma's website, the HD33 does support side-by-side and top-bottom 3D WITHOUT a separate box like the 3D-XL. It says, quoted from website: "The projector supports all HDMI 1.4a mandatory 3D formats, side-by-side format and top and bottom format to allow users easy hook up with peripherals that can deliver 3D content. As a full 1080p, it supports all 1080 p formats natively without needing an Optoma 3D-XL box converter box. As with all 3D displays, a 3D source (such as a 3D Blu-ray player or gaming system), 3D content and 3D glasses are required for 3D viewing."

How does the input lag compare to the Epson 3010? I'm a gamer so this is important.

Also, what about brightness. From what I hear the Epson is very bright; is this one at least bright enough to use during the day with the blinds slightly open?

I have an older Infocus IN76 which just bit the dust. Repair cost doesn't warrant getting fixed. Thought about the HD33 because of price and good reviews although I'm not too concerned about 3D.

Would this be a considerable uograde over my older IN76 in terms of 2D? I am projecting at 11' with 90" screen.

Does it have vertical stretch mode for CH setup?

Thanks!

What was the gain of your screen when you did this test?

These active 3D projectors work alternating the image between what your left eye sees and what your right eye sees. The glasses black out each eye in sync with the projector changing images. Your eye and brain average out the on/off brightness, so at best the image only looks 50% as bright as it would without 3D glasses. In reality, the synchronization can't be perfect, the on/off switch takes a small amount of time so each eye is off a little more than 50% of the time. So you will probably only get 30-40% of the brightness when watching 3D. If you measure the screen you won't see the difference, unless you measure it through the glasses. Even passive systems still lose over half the brightness, because the polarized lens cut out over 50% of the light.

Bill, one quick clarification - you mentioned in one of your responses that PC 3d and hdmi 1.4 3d are not possible without an adapter box - that is not correct, actually. Both ATI and Nvidia fully support directly outputting hdmi from a PC for movies or for games.

Nvidia I believe requires a 240 or higher (though keep in mind 3d gaming requires about twice the capability from the card), and ATI requires one of their 6xxx series cards. And of course the card must have an HDMI port.

So long as those requirements are met, you can do the following:

Assuming you have a bluray drive, bluray 3d plays from Cyberlink PowerDVD or Arcsoft TotalMediaTheatre to hdmi 1.4 via ATI card with no additional software (Nvidia requires the 3dtv play software).

90%+ games can operate in 3d using tridef or iz3d on an ATI card or using 3dtv play on an nvidia card.

The down side is that you have to make a tradeoff in reference to resolution vs framerate; since 3d over hdmi 1.4 does not support 1080p@60hz, you have to either run at 24hz or drop to 720p for 60hz.

Thanks for the answer Bill. I didn't think my question about potential 3d lumen light reduction in 3d mode was silly but maybe it was. Some of this stuff is very new to me. It was based on my reading of a number of reviews, including the review by Jeff Janis of the Acer 5360h, noting a significant lumen reduction when switching to 3d mode. According to the review, that projector measures at 2169 in normal mode and gets reduced to 698 in 3d. I guess I was just wondering if i could expect the same from the HD33. So given your answer, is there no drop off in brightness on the HD33 when you make the switch to 3d...thanks

Wow, a lot of comments! Thank you everyone for reading the article. I hope you enjoyed it.

I'll try to reply to all of you; my apologies if I miss someone.

Rick - no, we never had anything like that happen. Have you contacted Optoma support?

jamie - The projector is 100% 1080p. Lumens in 3D mode did not significantly differ from lumens in the other modes, and since you're never actually watching 3D mode without the glasses, we thought it was a silly measurement to include. I can go look through my notes if you'd like but it's around 900.

Lcoangeli - the HD3300 is an HD33 with ISF options, sold through authorized resellers and custom installers. As for your other question, you're sort of out of luck--the HD33 will do HDMI 1.4 3D but not PC 3D, while the GT750 will do PC 3D but not HDMI 1.4 3D. To do both, you'd need a projector like the GT750 plus an adapter box like Optoma's 3D-XL.

Luis - I answered Ken's question below, and then again to Lcoangeli. Actually, most of my answer to Lcoangeli applies to you; right now you can't do PC 3D and HDMI 1.4 3D on the same projector without some sort of adapter box.

Eric - passive 3D on projectors costs a lot more than you'd think, which is why you don't see it much. To my knowledge the only one around is the big LG dual-engine 3D machine from last year, and it was very large, very cumbersome, and image quality was not up to snuff for home theater. You can build your own passive system using polarizers and two projectors, but not many people do this now that prices on active-shutter 3D projectors are so low.

Regis - you'll be sacrificing some black level. You also lose the Epson 8350's excellent zoom and lens shift. As far as actual image quality, though, you don't lose much.

Pedram - MSRP is $2999; MAP is $1499. These two numbers often differ. Just to be sure, though, I have contacted Optoma to ask for a clarification. If we have made an error, it will be corrected.

Echeva - the HD33 is miles ahead of the HD67 on crosstalk.

EC Toy - That's all you need. Enjoy.

@ willdao Unfortunately it is only 1080i at 60Hz otherwise the fastest 1080p is 24hz. http://en.wikipedia.org/wiki/HDMI and a Tomshardware article done on AMD's open 3D gaming features. Some graphic cards have display port options but no consumer 3D projectors have them. Nvidia reaches 120hz by using two DVI, but I am lucky if a projector has 1 DVI cable. What I would love to do is create a circular screen and by tweaking the ini files make the image come out walleyed on a standard screen but fit the wrap around screen. My own 3D imax Oblivion or Skyrim to get lost in..mmmmmm

I'm very sensitive to crosstalk. Currently I own an Optoma h67 which also has virtually no crosstalk, though it has uncomfortable rainbow effect. How does hd33 compare with respect to crosstalk?, the review says virtually none, is it as non-existent, as the one in hd67?

Thank you for the the excellent reviews. No magazine, including Consumer Reports, provides the amount of unbiased info that you do! Does this, or any (lower priced)3d front projector use passive glasses? Library/Park District use would require very inexpensive glasses, cardboard framed polarized would be ideal.

Just purchased the HD33 based on the reviews. I'm going to be running it on a 110" diagonal screen. I'm not even ready for 3D applications yet, but for this low price, I might as well get it now. Visual Apex is also selling the RF glasses for $79 (vice $99 advertised). Just FYI.

I really love the reviews here, it helps a lot to protect our money and choose more wisely when buying these expensive equipments.

I have the same question as Ken, What significant differences are between the HD33 and HD3300 other than the price.

I was almost to submit a pre-order for a GT750E because it has more lumens and short throw but placed it on hold. Is it worthy of paying $700 aditional for the HD33 ($1499) instead of $799 for the GT750?

My primary use for it will be 3D gaming (from console and PC's), also as home teather with Blueray's and HD satellite programming.

Bill please give me some feedback on this!!! I am a rookie :-) I already have a screen with 1.3 in Gain (120" 4:3 format), my setup will be wide screen although I may have to shrink it to fit 108" of 16:9 format more or less. I have some trouble to control ambient light during the day and the projector will be installed on the ceiling with a mount extended 10" down.

I like better the new feature in the HD33 and 3300 for RF glasses than the DLP Link setup used by the GT750.

Is the warranty for the more expensive models (HD33 and HD3300) three years? For that price range ($1499-1999) I think is a must!!

regards

I was asking the same thing myself, Which are differences between HD33 and HD3300 other than the price?

I was almost to pre-order the GT750E because it has more lumens and short throw, Is it worth paying the $700 difference to get the HD33 ($1499) instead of the GT750 ($799)? I have the budget, but want to be sure of the correct item for my needs (that is: Console and PC 3D gaming, Home theater from Blueray and HD satellite service).

I really like the new feature for RF glasses on HD33 and 3300, I understand the GT only supports DLP Link glasses. Honestly for $1499, I would expect a three year warranty at least!!

PCentral you are the best; Love reading your reviews, it really help us to get the best for our money. Regards Luis

Thanks or your review. Good work. I do have a quick question tough:I thought that when I first saw this projector on the Optoma website that the 3d mode was 720p...can you clear up if both the 2d and 3d modes are in 1080p? Also, did you do a lumens measurement in 3d mode? Thanks

can't wait to get mine. I am really looking forward to this purchase. I was looking at the Panny and possibly the new Mits thats coming out but I think at this price point and the PQ review this just can't be passed up! Ordering this tomorrow. Hope it ships quick. Enjoy

Bugnguts,

I thought the HDMI 1.4 "a" revision addressed the 1080p/60 gaming issue?

I just received my HD33 on Saturday and picture looks amazing, but I am having a strange issue with it. I watched several movies and afterwards was unable to get it to respond the the remote or to the power button on the back. Video was still being played via HDMI but the projector was basically locked up. Thus has happen twice.

Did you see anything similar when conducting your tests?

Ken - the HD3300 is ISF Certified, so you can adjust gamut and have additional calibration options. It is also sold through authorized vendors instead of the HD33's open distribution model.

polkfarmboy - Projectors as a general rule do not dim in 3D mode. What happens is that the glasses make the projector appear much less bright than in 2D, though the projector is producing just as much light if not more. The dimming is a function of the glasses, not the lamp.

Luis - no 2D-3D conversion. If that's something you're after, they now make Blu-ray players that will do it for you.

Does the HD33 do 2d to 3d conversion? Your review doesn't seem to mention this so I figure that it doesn't.

Are all the light output modes the same brightness in 3d and 2d ? If so why does this unit not dim in 3d like all the others

If the light output is the same in 3d then I think I just found my new 3d gaming projector

Great job Optoma. I hope this will bring down the price of 3d projection, but I really would like to try gaming in 3d. Unfortunately HDMI 1.4 cannot handle the 1080 at 60Hz plus. So until display port or something with higher bandwidth is supported I can't justify the leap.

Can the HD33 accept a 1920x1080 120hz input from a computer? Some specs I've seen show it can only accept a 60hz input at 1080p. 120hz would allow 3d from an htpc at 60hz/eye.

Any differences in the Optoma HD3300?

Didier - yes, it is possible to use DLP Link glasses with the HD33. You can configure whether to use VESA 3D or DLP-Link 3D in the menu system. You won't need the 3DXL, though.

My apologies; while the projector I reviewed had a pair of glasses in the box, Optoma has informed us that glasses must be purchased separately.
