Optoma GameTime GT750E:
For Games and More

Marc Davidson, November 10, 2011


No Zoom. The lack of a zoom lens on the GT750E means that the only way to adjust image size is by moving the projector. This could become a minor annoyance for a portable projector you'll likely have to set up repeatedly in different locations.

Rainbow artifacts. Rainbow artifacts are potentially an issue for any single-chip DLP projector. More important, if you see the rainbows easily, you're more likely to find them annoying in a long game playing session or watching a movie than when watching a business presentation. With the GT750E I saw an occasional rainbow with data screens and saw them a little more often with video and games, but still not often enough to find them bothersome.

Unless you're both sensitive to the effect, as I am, and unwilling to accept seeing any rainbows at all, it's unlikely that you'll consider them a problem. To prove the point, I connected the GT750E to a FIOS box and spent a thoroughly enjoyable couple of hours watching movies in 3D, despite the occasional rainbow.

Doesn't include 3D Glasses. The GT750E doesn't come with 3D glasses, which means you'll have spend extra for them, at $70 to $100 each. Optoma says you can find the identical projector selling as the GT750 with one set of RF glasses. At $899, or $100 more than the GT750E, however, you won't save any money that way.


Somewhat ironically, the GT750E's tight focus on game playing makes it a good choice as a jack of all trades. By designing it to handle game images well, Optoma wound up with a projector that offers good image quality for both data and video too. And by adding a sound system that's good enough for games, it wound up with one that's also good enough for movies or business presentations with sound.

Being able to use the GT750E for data and video is a welcome extra, but the best reason to consider it is for its intended purpose, for game playing. The simple truth is that it's well designed for games, with good image quality, good audio, high enough brightness, support for both RF and DLP-Link 3D glasses, and fully 3D-ready. If you plan to play games, the GT750E belongs on your short list.

Hello every one, i am really newbie in this, i know the last post was on 2011,but this PJ seems good today and my question is about how important would be have a 1080p projector instead a 720p projector on a 100 inch screen it is noticeable for a untrained eye? the reason of my question is that this PJ is 520$ on amazon and a similar 1080p pj BenQ W1080ST its about 1078$ even Acer H6510BD 3D is 774$ i want to use it for 3d gaming and watch movies equally

does the gt750e play both full and half sbs 3d files...and if it down scales the half sbs 1080p to 720p then it means its ? 640 x 800 (1280 x 800 / 2) for each pic.....just want to know if it plays full sbs mkv files downloaded of the net so that the resolution is not too compromised in 3d...anyone out there tested this? would be appreciated..ty

The reason that it says there is no scaling for 720p is because it does not fill the screen when running 720p. It puts 40 rows of black pixels on the top and 40 rows of black pixels on the bottom. The a 720p screen fits within the 1280x800 so there is no stretching of the image. When you run the projector in 1080p scales the image within 1280x720.

Technically, your right. You cant say there isnt any scaling. The reason people say 720p anyways, is because scalling from the 800 to the 720, is very very very small. Downscaling from Full HD your going from 1920x1080-->1280x800. Now thats a big leap. Upscalling from 800x600 or even a native 1024x768 up to this 1280x800 is also a pretty big leap. But 1280x800 to 1280x720 is next to nothing.The 40 native downscaling on the height is not going to noticeably affect the image quality. But again, thats a whole different story when your upconverting from widescreen 480p (853×480) of regular DVDs to 720p 1280x800 (800) of this projector.

first of all this projector is one the cheapest 3d projectors out right is selling it for $678 with free shiping.and i have to say optoma definitely delivered on this one.i had the gt700 for a year and a half and it was a great gaming/movie projector.but the gt750e has some improvements.the image on the bluray movies and xbox 360 gaming looks brighter and has 2 hdmi 1.4 for unleashing the latest 1080p image.

Did you measure output lumens in 3D mode? Was it more comparable to Bright or Game? Thanks.

you guys say "a DLP engine with a native 1280x800 resolution, so you can show games at 720p without scaling."

how can it be "no scaling" by playing 720p content, if the native is 800p?

You guys have this PJ listed as 3D ready but in the review and on the specifics page you have it listed as HDMI 1.4a. What gives?

It seems like this PJ has it's niche, but it has to be careful because some other 1080p PJs are approaching 1K in street price.

The question is lag, and the question is lumens. This PJ seems to be a "gaming LANFest" type where you put it in your backpack and run. The short-throw helps with setting it up easily in a tight spot.

I just wonder, a 120" 720p vs 1080p image is easily differentiated, but maybe not with mainly 720p games.
