Optoma HD25-LV
Home Video Projector Review

Bill Livolsi, July 18, 2013

Similarities between the HD25 and HD25-LV

The HD25 and HD25-LV are more alike than different, and most of our Optoma HD25 projector review applies to the HD25-LV as well. Both projectors have excellent color balance, especially after calibration, and both feature a full color management system for fine-tuning the gamut. Both are native 1920x1080 with excellent sharpness and clarity, and full support of HD 3D is present in each. Both projectors have low 17ms input lag, making them ideal for video games. The projectors also have identical menu systems and take the same replacement lamp, which has an estimated life of 3,500 hours at full power and 6,000 hours in Eco-mode. Replacement lamps cost $399. And despite the large brightness difference between them, the two projectors have the same level of fan noise.

Both projectors also have some shared weaknesses. White balance is limited to a single axis of adjustment per color instead of the full gain/bias controls found on other home theater projectors. The preset image modes are all locked, forcing you to use the single User memory setting for your own calibrations. Both projectors have a 1.2:1 manual zoom lens and no lens shift, which limits the projector to table placement or ceiling mounts. Neither projector reaches the maximum light output listed in its specifications, either.

Differences between the HD25 and the HD25-LV

Higher light output. The HD25-LV produces just over twice as many lumens as the HD25. Bright mode measured 2420 lumens on the HD25-LV to the HD25's 1185 lumens. Cinema mode measured 2328 lumens to the HD25's 1146. Reference mode measured 2000 lumens (vs 982), while Photo mode measured 1993 lumens. Color balance in these image modes is roughly equal to their equivalents on the HD25, so you are not sacrificing color fidelity in order to gain the extra brightness.

Those who plan to set up the HD25-LV in a darkened room should be prepared for a very bright picture, even at screen sizes of 140" diagonal and larger. If the projector is too bright for your tastes, you can lower light output by engaging Eco mode, which reduces light output by 25%, or reducing BrilliantColor, which can reduce light output by up to 20%.

The HD25-LV's high brightness is especially helpful in 3D, where every lumen counts. 3D lowers image brightness significantly on both the HD25 and the HD25-LV, but the HD25-LV still has a significant advantage in light output. Whereas the HD25's 3D preset measured 682 lumens at default settings, the HD25-LV measured 1124 lumens under the same conditions. This does not account for the dimming effect of the 3D glasses, which we intentionally omit since neither projector includes 3D glasses. There are many different options available for 3D eyewear, using either DLP Link or an external emitter; just make sure the glasses you purchase are capable of running at 144Hz.

Black level. The downside of the HD25-LV's increased light output is poorer black level. While the difference is not especially large, the HD25-LV has a noticeably higher black level on a 0 IRE test pattern than the HD25, and the difference is maintained when viewing film and video content as well. The HD25-LV is a living room projector, however, and black levels in the living room are entirely dependent on the amount of ambient light in the room. With even a little bit of light in the room, the black level of both projectors are instantly equalized.

Sound system. The HD25-LV has a 16W stereo system (8W per speaker) while the HD25 has a 10W system. In larger rooms, the HD25-LV is capable of greater volume without causing audible distortion, making it particularly useful for portable use where no alternative sound system is available. The HD25's 10W system is perfectly suited to smaller rooms or video game use, and is in itself better than most other projectors offer in this price range.

Frankly, I do not understand how it is possible not to talk about fan noise in a exact way.

Both eval lacks the a fan noise section. The LV review says the noise is the same - but same to what level?

The forum section - not the proper place to give data - gives the info that it is a quite projector, but without comparing to specifically it is almost meaning less.

I think many of us interested how noisy the projector compare to the most quite one or wantsto see real data.

The manufacture provide databut it is not realiable, like the mpg for the cars. Japanese are much more accurate than US acar makers.

This kind of error (leaving out the noise factor) makes the review not credible. I do not understand how can be left out and more importantly why not fixed. I am not the first who pointed out / asked for this info.

It would be also usefull for the reviewers to concider reliability and QA. I know it is hard, but I find it misleading when they give a glowing review when it is known the unit has some serious QA problems. Sample of one may not reflect the performance of the product.

hi Bill thank you for great reviews. I am planning to buy a home video projector for my new house. there exists high ambient light in my living room, so I need a bright one. hd25-lv has good brightness, so I expect to have bright picture at 80 to 100 inches. optoma has announced two new models, hd26 and gt1080. considering hd25e, I can't decide between four optoma projectors. may I ask you to compare them as soon as new models are available? these projectors have many similar official specs, but some people believe that new low power models could not be as bright as hd25-lv. I am also thinking to new function indicators that projector industry needs. for me, lumens to watt is important, which I hope to calculate for new projectors you review. thanks.

I have just got this projector (HD25LV) but unable to get the best picture out of it so far. Can anyone please advise me the best possible calibration setting for a dark room on 1.0 gain matte white 120" screen.

Sorry to necro an old thread, but has anyone tried the newer HD25e? Seems like a great balance between the older HD25 and the HD25-LV. I am COMPLETELY new to projectors, but we are moving in a few weeks, and I was finally able to put together the budget to give a newbie-DIY home theater in our new finished basement a try.

Costco here in Canada has what seems to be an excellent deal on the HD25e + RF emitter + two pairs of Optoma RF glasses for $1099.00.

Thoughts?

Im trying to decide between two projectors. One being the Optoma HD25-LV and the Panasonic AR100U. I have 10' ceilings so i would need the image to be projected down to a lower screen. Can anyone help me out please???

Hi thanks for your very useful review. From your excellent site and review it looks like I will buy the HD25LV for my very first projector but am slightly unsure of the screen size to buy. I was thinking of a 145" gain 1, matt white. As all the physical numbers stack up. room is 7*4.4*2.7 Meters to false ceiling. can control the lighting but is the lounge so walls and ceiling are not black :)

but as watching 3D blue ray films at night using the RF glasses will be 50% of its usage was wondering if in 3D mode this size screen would be ok. Would appreciate your opinion

Thanks Ian

A to outdoor use

A very simple low cost almost perfect fix

Take heavy thick ply black (anything) like sheets or plastic from builders center that comes in a roll. Then attach to a light weight frame at top or a wire extending from each of the screens four sides. Put screen inside frame extending the plastic out 3-6 feet on all four sides of the screen. (you can fig it out)

This will offset the screen back 3-6 feet in a much darker environment. It will make the projected light stand out in comparison to the black housing around the screen. NOTE: you might want to weight the bottom down so wind thing you know. Also cuts dome half moons into the sheets to allow wind to pass through. You want to do your sailing on the water not your back yard.

When finished disassemble and roll each of the four plastic segments up on the suggested 1"x1"x8' polls/frame and store until next yard party.

Not perfect but a great improvement.

Ok. Let me know

FYI. I need 4-6 tickets for the 4th july

I just purchased the LV and it goes into use tonight. I have a new outdoor 220" and am having a movie night outdoors for my kids and all the neighbor kids.. I currently have a dated $16,000.00 Marantz DLP that just doesn't have the lumens for outdoors use.. I will update you all on how this Optoma HD25 LV holds up..

How does the HD 25-LV compare to the HD 33. Since the lumens are lower but the contrast ratio is higher! Which is the better buy considered the HD 33 is a bit seasoned already.

I've had the new Optoma HD25e for a week now, and am quite happy with it. I agree with comments that the lens is the weak point, because focus is a bit soft. The offset also require a bit more thought on placement. Other than that though, I really like this projector. In case it's helpful to anyone else considering one of the HD25 models, I've posted an Opinion plus Topics in both Home Theater and Projectors forums for more details. I'll try to check back here in the next few days in case there are any questions.

Edward - I did not, but I am not especially sensitive to rainbows. I would not be comfortable making a judgment either way.

chachanyc - While I haven't looked at the HD33 next to the HD25, I am inclined to say that the HD25 is an improvement.

Najeeb - Sorry, but I don't test TVs.

Sam - I don't know any projector that can do all of the things you want. Outdoor projection during the day is about the toughest application there is. Just be aware that you will probably need a smaller image size than you are imagining in order to get a bright picture. In fact, though I am by no means an expert, you might want to consider a television rather than a projector, because I doubt that 3,000 lumens will be enough.

Great review...thank you. I am looking for a projector that can handle dual use. Mostly it would be for use in my small living room that has ambient light (the light coming in would not be facing the screen, but instead would hit the wall behind the screen). I am less worried about this use. I also plan to take it onto my patio for nfl sunday game viewing. I have a big brown gazebo canopy that will cover the screen area and provide some protection from the daylight.

I think I need at least 2500 to 3000 lumens. What do you suggest?

My other concerns are that I want 1080p, decent color output, and also a usb input that i can play video from (think Chromecast). I dont care about 3d, but its a nice feature if it had it. Is there a projector you suggest around or under 1000? I am considering this optoma, the benq 1070, acer h6510bd. Any others that have it all and allow me to be greedy and get everything I want?

Thanks Bill for this detailed review. I m thinking to switch to HD25 LV from my 3D Lg TV 47LM8600. My main concern is about the black level of LV's in comparison to LG LM8600 (if u have ever tested that specific model). Kindly reply me ASAP.

How does this projector compare to the optoma hd33?

The Optoma HD25 and HD25-LV seem like good projectors that provide a good balance between price and performance. However, I hope they rise to the next level in terms of providing cutting edge features whilst being competitive. Example: Full blown colour management, better upscaling and noise reduction and most importantly better glass for a super sharp projected image. The classic InFocus projectors were absolutely loved for their sharpness and colour fidelity right out of the box. I remember the InFocus IN83 was a benchmark projector and to this day it is sought after in the used market. This is the sort of direction that Optoma should take and I believe it can very easily.

Bill, Did you notice more rainbows on the HD25-LV compared to the HD25? This might indicate a slower spinning color wheel which would allow for greater light output on the former. Or maybe the HD25-LV illuminates the same lamp with greater intensity. Did you measure electricity consumption for the two projectors?

Proji,

The HD25 and HD25-LV have the exact same fan noise. I have added a comment in the article to this effect.

As far as "how is that even possible," I do not want to speculate. Your suspicion that it might involve the color wheel is plausible, but Optoma no longer publishes color wheel information, even for their home theater projectors, so it is impossible to confirm. We have asked Optoma representatives several times for color wheel information but they have declined to comment.

Both the HD25-LV and the HD25 are actually very quiet in operation, but you are correct that Eco-mode is quieter still. Your idea of using the LV in Eco mode instead of the HD25 in full power is not bad, though the HD25-LV's black level is still not as deep as that of the HD25.

Goglen,

The HD25-LV's additional lumen output in 3D mode sounds like it would be beneficial to you. If 3D is a priority, I'd say go for it.

I've been waiting for this comparison for weeks - I need a replacement projector (my Panny AE700 is in its death throes).

However, I still can't determine if I should get the HD25 or the HD25-LV. I have a dedicated (dark) theater, so the HD25 seems recommended.

But, I have a 133" screen, and would prefer to run the projector in Eco mode. Not necessarily to make the bulb last longer, but to make it quieter and possibly generate less heat.

So, which? I don't want the image to be TOO bright... would Eco mode on the HD25-LV be OK for me? I'm leaning that way, because I'd be able to go to "full" for 3D if I need more brightness.

Thanks for publishing this long-awaited review, Bill! I have to admit though that I'm a bit underwhelmed by it as there's no statement on the noise level (which as I noted in my other comment, is very important to me). Does that mean noise levels are similar to those of the Optoma HD25? If so, how is that even possible? I mean, I really wonder how Optoma would manage to get double the measured lumens (2300 lumen vs. 1185 lumens of the HD25) out of a very similar device, seemingly without any major drawbacks (apart from slightly worse black levels which is to be expected)? Is it simply the Philips vs. Osram bulb? If so, I'd expect all other manufacturers to switch their bulbs as well, as it's literally a no-brainer then. Or/and does the HD25-LV have a different color-wheel, maybe with a wider (or additional) white sector? The fact that colors allegedly don't noticeably fade compared to the HD25 suggest that it might be the different bulb only indeed (as with a white sector in the wheel one would expect quite some color fading). On the other hand, as noted, I don't understand why not every other manufacturer uses the same Philips bulb then.

Another point regarding the audible noise level: Since the LV model has a so much brighter image, the LV model could perhaps also be a very good alternative for those potential buyers who fear that the HD25 might be too noisy, assuming the LV's noise in Eco mode is lower than in its normal mode (is it?). As even in Eco mode, the LV's 1725 lumens (-25% compared to measured normal mode brightness) are way above HD25's measured 1185 lumens. Any opinion on this idea, Bill?

All in all, if I trust your review, the HD25-LV looks like a clear winner to me. I mean, why even think about purchasing a HD25 or a Benq w1070, considering one gets more brightness (which can always be dimmed down using Eco mode and disabling BrilliantColor) at almost no disadvantage? I'm happy the HD25-LV seems to be a great projector for its money compared to its competition.

That said, I still regret that projector manufacturers don't seem to be able or willing to publish honest numbers about almost everything (like lumens, dB/sone, contrast, etc.).
