UST puts a 100-inch screen just inches from the wall. For gaming in a real living room, nothing hides cables and shadows better. The key is low input lag, smart pairing with a UST ALR screen, and clean audio via eARC.

Why UST for gaming
UST lives on the media bench, not the ceiling, so family rooms stay tidy. No player shadows, no tripping over tripods, and ambient-light performance is much better with a UST ALR screen. If you split time between movies and games, UST is the most living-room-friendly path.
How We Test and Score
We test UST in bright and dim rooms, with/without UST ALR screens, at 4K/60 and 1080p/120 where supported. We log HDR tone-mapping behavior and Dolby Vision when present. Port checks include HDMI 2.1, ALLM/VRR, and eARC. See UST vs Short-Throw (https://aixprojector.com/guide-ust-vs-short-throw/) and ALR Screens (https://aixprojector.com/guide-alr-screens/) for setup context.
Scoring (100 pts):
Input Lag 35% – 4K/60 and 1080p/120
Contrast & HDR 25% – with ALR vs bare wall
Practicality 20% – placement, noise, heat
Platform & Ports 20% – Google TV/Android TV, eARC, HDMI features
Input-Lag Targets
| Mode | Target (ms) | Why it matters |
|---|---|---|
| 4K/60 | ≤ 33 ms | Cinematic games, racing, RPG feel smooth and responsive. |
| 1080p/120 | ≤ 16 ms | Faster aim feel for shooters; great compromise for UST. |

Buying Tips
Screen first: A UST ALR screen transforms black level and contrast under lamps.
Audio path: Prefer eARC and “passthrough/Game” mode on soundbar/AVR to avoid audio delay.
Noise & heat: UST runs near viewers; quieter cooling and clear vents matter.
120-Hz modes: Some USTs offer 1080p/120; input lag must still be measured.
Apps & formats: Check streaming support and Dolby Vision where relevant.
FAQ
Can UST do 120 Hz?
Some models support 1080p/120. Check Game/Low-Lag modes and measured latency.
Do I need an ALR screen?
For bright rooms, yes. UST ALR preserves contrast and color saturation.
Is UST lag higher than short-throw?
Often slightly, but still playable—especially at ≤ 33 ms for 4K/60 and ≤ 16 ms for 1080p/120.
Does eARC add delay?
Use passthrough/Game mode to minimize processing in the AVR/soundbar.
Will Dolby Vision help?
With good tone-mapping, DV can preserve highlights and shadow detail at 4K/60.
Ready to Choose?
Map your room, pick a UST ALR screen, then shortlist models that hit the lag targets.
