Optoma GameTime GT750E:
For Games and More

Marc Davidson, November 10, 2011

Strong Points

Good data image quality. Since some game screens share the same characteristics as data screens, it is important for a game projector to handle data images well. The GT750E does well enough on this score so you can use it as a data projector.

On data screens, colors were a bit dark in terms of a hue saturation brightness color model, but they were fully saturated and suitably eye-catching. Yellow was a touch mustard color, but no more so than with most DLP projectors. Note too that text was crisp and readable down to the smallest sizes we test with. The text was easy to read even in an assortment of color combinations with color text on color backgrounds.

Good video image quality. The GT750E's video quality is easily a match for some low-end home theater projectors and better than you'll get from most data projectors. In my tests, it handled skin tones well and did an acceptable job with shadow detail. I saw a slight loss of detail in scenes that tend to bring out the problem because they're not lit well, but poor lighting (or, rather, it's digital equivalent) is an issue you're not likely to see in games.

I saw some moderately noticeable noise in large areas like the sky or a solid blank wall, but no more than with most inexpensive home theater projectors. I didn't see any motion artifacts or posterization (shading changing suddenly where it should change gradually). More generally, the GT750E's video quality is good enough that I'd be comfortable using it to watch a full-length movie.

Good Game image quality. Good image quality for both data and video almost necessarily translates to good image quality for games, but to confirm it I took a look at both Batman: Arkham Asylum and MLB 10 The Show. The projector handled both the dark Batman scenes and the bright baseball scenes without any problems, and also without the noise I saw with video.

Short throw lens. Thanks to its short throw lens, the GT750E can easily throw a large image in a tight space. For my tests, I measured a roughly 90" diagonal image at 720p at just 57" from the screen. That puts the projector close enough to the screen to let you sit behind it, not have to worry about shadows, and still have an image that fills most of your field of vision.

Fully 3D-ready. The GT750E is one of the few inexpensive projectors with HDMI 1.4a ports, so it can accept a 3D signal directly from a PlayStation 3, a FIOS box, or the equivalent. I tested it with 3D games, Blu-ray discs, and HBO's 3D content on FIOS and it worked as promised, with no problems and with no noticeable crosstalk.

Portable. At 3.8" x 12.8" x 9.2" and 6.6 pounds, the GT750E is small enough to carry easily. If you want to use it occasionally as a data projector for business presentations you may want to get a second carrying case. The included black backpack with red and gray highlights doesn't look businesslike, especially with the words Game Time showing clearly in large letters.

Good quality audio. The GT750E's sound system is far better than what you'll find in most projectors its size. In fact, the two 5-watt speakers offer stereo at high enough volume and high enough quality to match a typical large screen TV, which means you can do without an external sound system if you like.

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.
