Optoma GT750 Projector - Physical Tour

Posted on July 14, 2013 by Art Feierman
Writing up our Tour of the Optoma GT750 proved an easy task, since it is nearly identical, physically to the GT720 which we already reviewed. Much of this page is updated from the older Optoma projector's review.

Optoma GT750 Projector - Appearance

Black and shiny with some sculpting makes for a reasonably nice looking projector. A work of modern art, though, it's not. The fairly large convex lens protrudes from the GT750 front. You don't want to be bumping into that lens. The lens cap, I should note, fits snuggly when you get it on. Since the lens is unprotected without it, and an easy target, be sure to put it on properly if moving the projector.

Optoma GameTime 750 is a 6.5 pound projector. The front consists of the off-center mounted lens, an infra-red sensor for the GT750's remote control, and a large exhaust vent.

Below, there are adjustable feet. Unfortunately, I don't believe there is nearly enough adjustment range in the feet. The short throw lens combined with the amount of lens offset, had me sliding blu-ray movie cases under the rear feet to get enough tilt to get the image on my screen instead of partly above it, when using a table only a few inches shorter than the screen. If you are really moving this projector from location to location, you'll appreciate my complaint in some of those setups.

The top of the GT750 has the control panel, which is discussed below, in detail. All the inputs and other connectors are located on the back of the GT750.

GT750 Control Panel

The control panel consists of some buttons on that curvy bar, and a typical round navigation area. From the left, an AV Mute, and the Menu button. Then the Navigation, with a center Enter button. When not navigating, the up and down arrows handle keystone correction, while the left arrow does Source selection and the right arrow offers re-syncing for your PC signal, should it be needed.

On the right is the power switch - the usual press once for On, and twice for Off. Below it, three indicator lights for power, lamp, and temperature.

GT750 Projector - Input/Output

Beyond that major change, the GT750 offers a pretty standard selection of inputs. Ther is also PC input - a standard HD15 connector, which can handle analog PC, or component video. Other inputs include the usual S-video, composite video and a serial RS-232 for command and control. Stereo audio can come over the two RCA jacks, and HDMI also carries audio.

There is an Audio Out, which is a great thing for a gaming projector to have. While the GT750 has good sound for what it is, there's nothing like big sound. The output is a stereo output, so you could feed a larger stereo, but, the real, best value, in having the stereo audio out, is that you can use it to drive a small powered sub-woofer. And that should make your gaming (and movies) rock a whole lot more! Some of those subs are small enough to carry around - weighing under 10 lbs. So, take it to a friend's. That way, you can get your friends in trouble.

Lastly, there are three indicator lamps below the power button, the usual mix - Lamp, Temp, and Power. Pretty standard stuff, as I said above, but this Optoma GameTime projector has the inputs it needs to handle just about any type of 3D you can throw at it.
