Behind This Door – Projector Number 1: Optoma GT750 Game Projector

Greetings everyone, just a heads up.  I’m finished with the 3D capable, Optoma GT750 gaming projector review, except for:

1.  Finishing writing up the projector review and posting it.   I’m trying for late tonight, but definitely posted by end of day Sunday – Oct 2.

2.  Getting to the bottom of why I’m having problems getting their RF – VESA 3D glasses to work.  Note, that their older DLP-Link glasses work just fine.  I will update the review in a few days when I have that solved.

3.  Getting feedback from Pete, who got to play with it for gaming, then sent it to me for the full review.

4.  Scott S (Ebeneezer Stooge), our other gaming blogger just picked the projector up from me, two hours ago, for his take on its gaming abilities. He, like Pete (Bitbound) will write up their opinions on their respective gaming blogs, and provide me a summary to include in the review itself.  (Obviously Scott S’s input will be posted after the review, since I won’t have his feedback for several days.

The long and short of the GT750 gaming projector from Optoma:

  • 720p native resolution
  • Very short throw – sits only about 5 feet from the screen to fill a 100″ diagonal 16:9 screen
  • Supports 1080 resolution 3D content, including Blu-ray 3D, works with all 3D content I’ve recorded from DirecTV as well
  • Rather bright – respectable brightness for 3D, in brightest mode, over 2000 lumens, does very respectable job on 3D at 100″ diagonal sizes, unlike many far more expensive projectors that are at best, half as bright
  • Lightweight (under 7 lbs.)  and portable (even comes with its travel backpack)
  • Includes one pair of active glasses
  • MSRP:  $799

OK, stay tuned for the imminent review of the Optoma GT750, Optoma’s soon to be shipping flagship GameTime projector.  -art

    In 2011?

      Sorry, should have updated, I occasionally forget that I have a life, that can conflict with my invariably optimistic estimates. In this case one part of the delay was my daughter having midterms. I didn’t get most of the images back until last night, but I was also running behind. -a

    when will this review be posted ?

    • http://www.projectorreviews.com/members/lisasonfeier/ Lisa Feierman

      About an hour ago, although as usual, bits more will be added including images, comments, and Proofing.

    Thanks for the extensive review Art.

    Couple of things I noticed :
    - picture of Lorne Green links to a picture of a lion in the snow
    - Under lamp life, eco mode is stated as 4000hrs, while in the overview more at the top it says 5000hrs

    • http://www.projectorreviews.com/members/lisasonfeier/ Lisa Feierman

      Hi Yanic, I’ll fix the lamp readings – not looking at them right now, but I do recall, that Optoma had two different claims to sort out. I think I may have changed one location, but not the other. Catching a plane in a few hours, it will have to wait.

      I’ll figure out the other picture, but may I assume you are talking about Ernest Borgnine (McHales Navy, etc.) (our image, from the movie Red). Lorne has been dead for some time, I believe (Bonanza). -a

    a quick answer on hd750 compared to the hd33, how much worse is the image quality of the hd33?

    i just asked the following in hometheaterforum.com, but i would have posted the question in the comment section to your reviews first, if i had found one.

    “thanks very much for the review(s), but i am really missing your subjective comparison of the hd750 and the hd33. i currently could have the hd33 for just a little bit more than the hd750, but many years ago i had a bad experience with a projector with very bad detail in the darker areas, and… generally no black level to speak of.

    in Art Feierman’s review pictures (after calibration) of the hd33 seem to have a lot less detail than that of the hd750 (train in the woods example), but i just found the uncalibrated pictures of the hd33 as well, and there i see that much more detail than in the calibrated pictures is possible, probably at the cost of black levels.
    also, for the review they never calibrated the hd750.

    so… how fare the two compared to each other after your reviews?

    thanks very much in advance for a quick reply, if possible, since i dont know if that low price for the hd33 stays for long in my currency.”

      Gani, the HD33 has the better picture quality. The GT750 though has the kind of phenomenal dark shadow detail that I only see with projectors with relatively poor black levels. The GT750′s biggest advantage is brightness. It’s a light canon, whereas the HD33 is merely “fairly bright”.

      The big differences are black level performance (the HD33′s pretty good, for the price, the GT750 – definitely not a match. And of course, the HD33 is going to be sharper, being a 1080p projector, not a 720p projector.

      So, the real question is how much better, and what are you doing with your projector, the room, etc. For example, most non-enthusiasts – seeing two fairly similar projectors, one with just a slightly better picture, but not quite as bright, and the other – the opposite. Most folks will simply prefer the slightly brighter projector. But, if you are into movies, etc. you will really appreciate the black level differences. Now, budget allowing, if you are considering the HD33, definitely also consider the Epson 3010, which I’m working with. It’s got the HD33 beat in many ways, for the same money. (The HD33 has its strengths too, but I’m more impressed with the Epson as you will see from the write-up… -a

    …GT750, not hd750… sorry for that mistake

    and after taking a third look at the train shadow detail pictures, the hd33′s looks so much less natural and overly bright compared to the gt750…. i hope you take a third look at those pictures as well and can tell me how much i should value this particular picture comparison.

    • http://www.projectorreviews.com/members/lisasonfeier/ Lisa Feierman

      gani, don’t be looking for natural. Those images are overexposed by something like 6-8 f-stops. Small differences in gamma, and other things will just distort any naturalness issues. Also one is brighter than the other, because of exposures. Just about all of the train images end up within about one f-stop of each other, which is still a huge degree of difference.

      The two images should be bright enough to lift the darkest shadow detail and make it visible. In some photos of the train, the info just isn’t there, despite the overexposure. Especially on the shrubs on the right – behind the track.

      The image can also be used to compare black level performance. Assuming two projectors have the same brightness to the letterboxing, then the one where the scene is the most overexposed, is the one with the better black level performance. OK? -art
