Optoma GameTime 750 3D
The projector supports all HDMI 1.4a mandatory 3D formats, side-by-side format and top and bottom format to allow users easy hook up with peripherals that can deliver 3D content. As a full 1080p display, it supports all 1080p formats natively without needing an Optoma 3D-XL box converter box. 
However, it is a bit misleading as output is only 720p.
What it does require is a pair of active shutter glasses and emitter. The review unit came with a set of Optoma 3D-RF glasses and 3D Sync emitter. I am not personally a huge fan of 3D just yet as the glasses make you look, at best, like Roy Orbison and at worst like a big dork. Not only that, but I’m not a glasses wearer to begin with so they are unfamiliar. Additionally, if you are bespectacled, you will then have to wear these over your standard prescription glasses and I can’t imagine that being comfortable. Plus, you have to be pretty much dead on to the projection and of course, you can’t lie on your side or change your head angle too far from center, all things I tend to do when at home enjoying some video-based entertainment.
Surprisingly, the Optoma GameTime 750 DLP Projector performed admirably in regards to 3D and I didn’t mind wearing the glasses while watching some video or playing some games in 3D. I couldn’t game for hours on end like I would normally but I did manage to watch some short-form 3D video content and play some games off and on. I suppose that with some further experience I would be able to extend my viewing or simply need to take some periodic.
The quality of the 3D image, even just projecting onto the wall (this we also tested with a projection screen) was astounding. To see a 3D image coming from a projector so small and cost effective was just, well, awesome. Gaming in 3D was pretty cool. We tested Killzone 3, PES 2012 and some others.
The only major drawback, is that, while the emitter can send to an unlimited number of 3D-RF glasses, they must be Optoma glasses because of the specific frequency. Therefore, you can’t have friends come by with their own, you can’t have multiplayer 3D gaming without purchasing multiple pairs and they must all be from Optoma. They’re only available from Best Buy apparently.
Finally, the glasses aren’t all all comfortable nor designed with comfort in mind. They’re hard plastic, unattractive glasses that rub roughly against the nose. I’ve actually padded mine with some sticky foam I had at the office to allow for a more comfortable sitting and longer gaming.
Optoma GameTime 750 Performance: Gaming
The 2D gaming performance of the Optoma GameTime 750 was flawless, as expected at this point. The picture was crystal clear and bright and gaming has never been such a joy. Playing Pinball FX 2 with a display this large and responsive was just outright fun. In fact, all of my gaming has been more interesting and engrossing since I got the projector. It’s held my interest for hours at a time whether on the consoles or the PC. Because of the multiple connections and the proximity of the desk I have been able to take my PC gaming to the huge display and that just makes it all that more fun.
Overall
In a nutshell, I never want to play video games without this projector again. Whether it be 
console or PC, 2D or 3D the Optoma GameTime 750 performs amazingly and really brought the games to life. On top of that it’s performs extremely well for all manner of other video entertainment whether action-packed or not. The built in speakers accented the home theater center and allowed for a more rounded sound and immersion as there is now sound coming from front, back and middle of the room.
Considering that nearly every projector on the market is over $1,000 for this type of quality and experience, I can’t see how they did it. At $799.99 it’s an amazing value and, if you’re considering getting a new large screen LED or Plasma TV, you might reconsider and take a look at this, especially if you’ve got as many uses for it as I have. It’s been used outside for film night, in the office for gaming, at home for sports and movies and the picture has proven to be quite good in all aspects.
Correction: The Optoma GameTime 750 accepts 1080p input but only displays up to 720p.
