Optoma UHD35STX review

A short throw projector for rooms too small to place a conventional one.

The verdict: The UHD35STX solves a specific problem: a 4K image in a room too shallow to place a conventional projector far enough back, with low enough input lag for gaming. Buy it if your room is short but you can still mount or place a projector several feet from the screen. Buy an ultra short throw if the constraint is severe, because short throw is not the same as ultra short throw and the difference is several feet.

What it does well

Where it falls short

What owners report

Owners describe it as the projector that fitted when nothing else would, which is the clearest signal of what it is for. People in small rooms and apartments report satisfaction with the compromise; people who bought it without measuring report the same disappointment that catches out every short throw buyer.

Gaming performance is praised consistently. Edge sharpness and geometry at the corners are the most common technical criticism, which is characteristic of short throw optics generally rather than unique to this model.

Alternatives worth considering

For Severe Space Limits
Hisense PX3-PRO Ultra Short Throw Triple Laser Projector
~$2,800

Sits inches from the wall rather than several feet, which is a different category of space saving. Much more expensive and requires an ALR screen, but it solves constraints short throw cannot.

Better Gaming, Longer Throw
BenQ TK700 4K HDR Gaming Projector
~$1,200

Similar money with stronger gaming credentials, if your room can actually accommodate a standard throw distance. Measure before choosing between them, since geometry decides this rather than features.

Common questions

What is the difference between short throw and ultra short throw?

Distance. A short throw projector needs a few feet between lens and screen. An ultra short throw sits inches from the wall, directly below the screen. If your problem is a room that is somewhat shallow, short throw is enough and much cheaper. If the projector has nowhere to go at all, only ultra short throw solves it.

Will it fit my room?

Measure the distance from where the projector can sit to where the screen will be, then check that against the throw ratio for your intended screen size. Our room planner will do the arithmetic. This is the mistake that catches most short throw buyers, and it is entirely avoidable.

Is it good for gaming?

Yes, low input lag is one of its selling points, and it doubles as a gaming projector rather than being a film projector that tolerates games. For a small room where a large gaming image seemed impossible, that combination is the appeal.

Why are short throw projectors less sharp at the edges?

Producing a large image from a short distance requires aggressive optics, and the corners are where that shows first. It is a characteristic of the category rather than a fault, and at normal viewing distances most people stop noticing it quickly.
