Our take on the Optoma UHD35STx

The Optoma UHD35STx is a short throw 4K DLP projector built for gaming and home theater. It throws a 100-inch image from just over 3 feet, puts out 3,600 lumens for lights-on viewing, and hits 4.2 ms input lag at 1080p/240 Hz. Its 1,000,000:1 contrast claim and HDR support give punchy, colorful pictures, and the 24 dB rating makes it quieter than many lamp projectors. Against rivals like the BenQ TK700STi, it trades a fixed lens with no zoom for a lower price and a brighter image, and owners report strong picture quality but also dead pixels and DMD chip failures after the warranty ends.

Questions and answers

Is the UHD35STx good for gaming?

Yes. It runs 1080p at 240 Hz with 4.2 ms input lag and 4K at 60 Hz with 16.9 ms, which suits fast competitive games and console play.

How far from the wall does it need to be?

Its 0.5 throw ratio gives a 100-inch image from just over 3 feet. The lens is fixed, so you size the picture by moving the projector, not by zooming.

How bright is it?

3,600 lumens, enough to watch sports or play games with the lights on. It dims somewhat in a bright room but stays usable.

Does it come with a streaming stick or apps?

No. The box has the power cord, two AAA batteries and a basic manual. You add a streaming dongle through HDMI and can power it from the USB-A port.

Is it better than the BenQ TK700STi?

Both are short throw 4K gaming projectors. The Optoma is brighter and quieter, while the BenQ offers a zoom lens and a stronger reliability record.
