Optoma Gametime 750 Set up
The Optoma GT750 comes with everything you need to get hooked in and up and running. One of the things I really like about the projector from the setup point was the enormous amount of inputs which include a VGA, two HDMI, S-video, RS-232 and RCA video. On top of that there’s also both RCA audio in and a 3.5mm audio out for a set of headphones. The final port on the back is the VESA 3D Port which plugs into the transmitter for the active shutter 3D glasses. The unit I received had a set of 3D active shutter glasses. The Optoma GT750 also comes with a backpack so you can quickly organize and carry your projector, if you wanted to take it over to your friend’s house or somewhere else.

All three feet on the projector have height adjustments and there are buttons right on the unit for vertical keystone (to make up for the proejction angle), menu, and re-sync. The remote control helps you navigate the menus as well an also offers volume control for the built in speakers as well as quick mode and input changes.
Overall, setting up the unit and getting it sorted image-wise took all of 10-15 minutes. I then took it outside to project onto a sheet on the side of the house to watch Raiders of the Lost Ark on a 10-foot-wide area. Again, some minor image manipulation and we were ready to roll film for the Saturday night sit-in theatre.
Optoma GameTime 750 General Performance
The projector is throwing an 8-foot diagonal image onto a wall which is painted plain white here in the office. We’re waiting on delivery of a 12-foot projection screen to mount for a larger image. The GT750 is about 5-feet from the projection surface so that gives you an idea of what kind of wide-angle lens the unit has. There’s actually a cool calculator on the Optoma GameTime 750 product page to tell you how far it would need to be and checking my numbers above, a 5-foot throw would make an 8.17 foot diagonal at 16:10 and an even 8-foot image in 16:9 widescreen. If we want to get a 12-foot diagonal image at 16:9 the unit will need to be moved to 7.7 feet and with low ambient light should still cast a bright enough image to enjoy. They say, at that size, the recommended seating distance is 15 to 23 feet, with the setup as is 5’/8.2’ we should be sitting 9-15 feet away, and we are.
The Optoma Gametime 750 DLP Projector performs extremely well. The 3000 lumen bulb is bright enough that it can be used for all but the darkest games and video even with light shining in from three small and one large window. Granted, there’s some color washout but not enough to affect enjoyment for the most part. Simply closing the blinds blocked enough light to return the image to a quality where none of the action was missed.
Everything we threw at the Optoma Gametime 750 it handled with ease. Fast-paced action, no problem. Films full of dark scenes and low ambient lighting situations, no problem. Car chases, fight scenes, animation (CGI and hand drawn) all appeared clear, bright and crisp.
Digital cable is an odd beast as there are several layers of resolution being pumped out. That sometimes means that the projector needs to re-sync with the source when you switch from full HD to a lower res or vice versa. The time it generally took to do so was not so long as to be annoying. Of course, moving to a smaller resolution means the picture was shrunk to that size. Our digital cable pumps out 480i and 1080i and switching from one to the other wasn’t a problem for the GT750. Output would then switch from 480i to 720p (max resolution of the projector)
Now I know some purists might want to talk about color accuracy and all sorts of technicalities but even just on the wall the picture was quite good. The addition of the projector screen we happened to have made it all that much better and there are enough options for the color and image to find something that looked perfect to everyone in the room at the time of testing.
