Street Price: n/a
$1,699 MSRP

At $999 street, the Optoma HD37 is a step up in price from the least expensive 1080p competition. It offers some conveniences, most notably a modest vertical lens shift, to justify the cost. But its main appeal is image quality suitable for a traditional home theater combined with both a brightness level that makes it a good choice for home entertainment and a lag time that makes it suitable for gamers.

Viewing Experience

One of the HD37's extras is support for ISF (Imaging Science Foundation) Certified day and night viewing modes. To take advantage of them, however, you need an ISF-certified technician to calibrate the projector, which will typically cost $250 or more. Optoma readily agrees that few people who are buying this inexpensive a projector are likely to get it calibrated, but you can if you want to.

Even without calibration, the HD37 scores well on image quality. Colors don't pop in theater-dark lighting the way they would with a high contrast ratio, but they're in the range of good to near excellent. And keep in mind that a higher contrast ratio doesn't do much with lights on. Ambient light in a living room will swamp out dark shades on screen, effectively lowering the contrast ratio in any case.

More generally, the projector handles color well. Skin tones and memory colors, like grass and blue sky, were well within the range of acceptable with all predefined modes in my tests. Color balance is excellent, with impressively neutral grays at all levels in all predefined modes.

I saw a slight loss of shadow detail in the most demanding scenes, but it was so minor that if you don't know what the scene should look like, you won't notice it. I also saw some moderately obvious noise with movies on DVD even with noise reduction at its top setting. I didn't see the problem with movies on Blu-ray discs.

For 3D, the projector delivers all the same strengths as with 2D for those aspects of image quality that both share, and it does a good job with issues specific to 3D as well. I saw no crosstalk and only a slight hint of 3D-related motion artifacts on scenes that tend to cause these problems.

For both 2D and 3D, I saw rainbow artifacts rarely enough in most scenes that it's hard to believe anyone would be bothered by them. The one exception was a black-and-white clip, where they showed too often for comfortable viewing.

One other potential issue is that if you're sensitive to fan noise you won't want to sit too close to the HD37. Optoma rates the noise at 29 dB in Eco mode. I didn't notice any obvious difference between Eco and Bright lamp settings, but noise is noticeably louder and a higher pitch in High Altitude mode, which Optoma recommends using above 5000 feet. Even in Eco mode, the whooshing white noise is audible ten feet from the projector. On the other hand, with the speaker volume set to a comfortable level, I didn't notice fan noise even from three feet away when watching movies.

OK, I hate to be "that guy" (though I probably am), but this sentence makes no sense to me:

«Even in Eco mode, the whooshing white noise is audible ten feet from the projector. On the other hand, with the speaker volume set to a comfortable level, I didn't notice fan noise even from three feet away when watching movies.»

Let's say I'm watching a dialogue heavy film (among media types that doesn't involve constant noise). Some of the dialogue is very quiet. There may also be some important background sounds. What will I hear during these scenes? The projector's fan. Is it good for the media *watching* experience? No.

I think you covered it well enough elsewhere; this projector is not quiet. Projector companies need to be taken to task for this issue, rather than receive excuses. Happily I'm seeing more and more reviews mention fan noise. This means we're coming to a plateau. This plateau can only be reached with attentive reviewers for all levels of projectors. This site is important in this quest.

I wish they would start using hdmi 2.0 so we can run pc games at 1080p120

With your dislike of fan noise, I can understand why you read the two sentences as contradicting each other. However, the fact that you can hear the white noise from ten feet is an objective observation, while the fact that I didn't notice the noise while watching movies is strictly subjective. I tend not to be sensitive to white noise, probably because I was brought up in a house less than 100 yards from a parkway, where the white noise of passing cars was a constant in the background.

As a reviewer, I try to give readers the information they need to decide whether a given issue will bother them, rather than focus on what bothers me. My aim with these comments was to let people like you, who are particularly sensitive to fan noise, know that it's audible from a distance, but also let people like me, who aren't as bothered by it, know that it's not so bad that it will annoy you even if it's not one of your pet peeves.

Is this projector noisier than Benq W1070? I am so sad that year after year they don`t do anything this problem. Too much noise. These are for HT use, make it little bigger with bigger fan to get more quiet. Use more expensive fans and up the price. I pay it. It just doesn`t make sense that you have to buy Sony HW40ES to get silent projector. And that one isn`t cheap!

Hoping to see some new more silent projectors at Cedia october. I can always dream.

Yes, the HD37 produces noticeably more audible noise than the BenQ 1075/1070. It is higher in pitch and somewhat louder. The BenQ units have a lower frequency whisper and are lower in dB as well although we don't have a sound room to do an exact measurement. When you drop the HD37 into eco mode it has no effect on the fan noise, so there is no way around it.

I was wondering if the DLP Link 3D glasses would be better for this projector or the RF glasses. I've tried browsing the web for answers but most of them were posts from several years ago. Any advice would be much appreciated!

I've just read the reviews you've posted for these two projectors: LG Electronics PF1500 Optoma HD37 Projector

They both have about the same street price - - but very little else appears to be common. My initial read is that the LG might be slightly better than the Optoma. Based on your "hands on" with both of these projectors, would you agree??

Also, if I was to use either of these projectors in a HT set-up, how would the projected video compare to the same video on a HD TV??

Does the HD37's measured input lag of 33 milliseconds vary across picture modes?

Hello, I am seriously considering buying this projector but would love some insight into people's complaints about the noise. I currently have an Optoma HD20, and I love it. I measured it's fan noise from a distance of about 3 feet and it read about 40-45 dB. That sounds like a lot but I can only hear it if my stereo is on mute, and my projector is directly over my head. I feel like complaints about noise are well over blown. My question is that given the rated noise from this projector is 29 dB, is there a particular distance from the projector that this 29dB is measured? If it's less than 5 feet or so, then I see no reason to fret.

@Chris I just upgraded from HD20 to HD37. You should really be aware of the noise. I would not say that I regret this purchase, but after one complete week, this is the only downside.

If you want, since I still own both HD20 and HD37, I could make a noise comparison for you?
Chris Posted Jan 23, 2016 7:36 AM PST
grimzkunk, I would greatly appreciate a noise comparison. Would you make recordings at the same distance, perhaps 4 or 5 feet away? I really appreciate it. It would be very helpful.
grimzkunk Posted Jan 26, 2016 8:37 AM PST
Chris I did a recording from my smartphone but they sound the same. I also used a decibel app, and surprisingly the HD20 is 2db louder than HD37.

HD20 @ 32db HD37 @ 30gb

Probably the HD37 high pitch is not considered in DB calculation. I think must complains come from people that are enabling "Dynamic Black" feature, which make the fan even louder than in my DB test.

I'm probably complaining for something normal. Sad thing is after many research, there is no quiet DLP projector in this price range.

FYI I also brought an Epson Home Cinema 3000. Did heard it was a silent projector, great bang for bucks. So I gave it a try (thx Costco for easy refund). The HC3000 had just too much light for my dark setup. Out of the box colors were ugly. Even after my amateur calibration I was already missing the HD37. It did have the same amount of DB than the HD37, something like 30-32db, but much more like wind, no high pitch the HD37 had (probably color wheel).

End of story, I also refund the Epson HC3000, and had to change my budget range and brought the Sony HW40ES, which is really dead silent. I also much more felt the quality upgrade from-HD20-to-hw40es than with both HD37 and HC3000.

I have not tried BenQ projector, but i'm pretty sure decibel is the same. So i could easely conclude this : when reviews are saying that a sub 2000$ projector is silent, well, it is not.

If you're like me and does not want to hear the projector in a quiet movie scene, or when listening low volume TV program because someone is sleeping near upstairs, or if you have a wooden stove near the projector....well, you gotta go with the Sony HW40ES, which is probably the only 2000-3000$ home theatre projector. Forget the Epson 5030ub, this one is not quiet at all.

Hope it helps someone!
