Optoma GT750 3D Gaming Projector First Look


The new GT750, with its DLP Link 120Hz 3D-capable display technology, or RF 3D technology options, not only does it support computer gaming 3D but also Blu-ray and broadcast 3D with a $799 MSRP.

Optoma GT750 GameTime


The Optoma GT750 has a number of improvements, while many of the features and performance are essentially identical. The most major improvement is the addition of support for 1080 resolution 3D, including Blu-ray 3D

For the price of a 42" 3D LCDTV, you can have 90" 100", 120", or even larger, for game playing. Talk about immersive ; Both of our gaming / projector bloggers found that the GT750 is a good gaming platform, especially for the money. No lag, good shadow...

Black level performance is weak, although with great shadow detail generally good for gamers ; Color could be better, but very respectable for the type of projector and the market it's targeting ; 3D color is off more, but that seems to be pretty...

Are you game? the Optoma GT750 obviously is! By adding the 1080 3D support, this new GT750 projector should appeal to a much larger audience than the older model. Realize, all that extra ability comes with a price that is essentially $50 more than the...

Optoma GT750-XL


Looked at lots of projectors and chose this one because i wanted 3d and hd. Its only 720p but dont let that be an issue. Picture quality is superb and is not too bright even in a dark room. Although you can turn brightness down. Colours are excellent....

Sometimes it keeps searching for imput but if you deselect non used imputs its fine. Short throw is good but projector needs to be in middle of room.

The size of projected image for the money spent is very good value for money.

The resolution is not very good - doesn't seem to perform as claimed on the box.

Optoma GT750-XL


Mounted the projector 1.5 m from the screen, this gave me an 84 inch picture, ideal when kids are stood in front of it playing games. (no shadows on screen).Colour and picture spot on, easy to set up for 3D viewing.

Nothing to do with the projector! but purchasing an extra three pairs of 3D glasses prooved expensive (£160 off Amazon)

excellent screen size and definition, home cinema in a small room thanks to the short throw lens. truely epic when hooked up to 5.1 system and full size video games , as good as it gets on a budget

the only problem i had was that the 3d glasses supplied didnt work, but optoma replaced them within the week, excellent service optoma

Fantastic i watched star trek on blueray and was blown away with the Q of image the three D image out of the box was amazing watched Avatar just like the pictures games Mch no problem added bonus

The lack of zoom means you just move the projector to gain the size of pic
