Chasing wins? For shooters and rhythm games, speed beats pixels. A great 240Hz projector at 1080p with low input lag feels tighter than a slower 4K image. This guide shows how to pick true 1080p/240, keep latency in check, and set up for clean motion.

Why 240Hz matters

At 240 Hz, frame time is 4.17 ms vs 8.33 ms at 120 Hz and 16.67 ms at 60 Hz. That cadence improves target tracking and flick timing. Many players report better aim “feel” at 1080p/240 than at 4K/60. If you play tactical shooters, this is the most practical path to performance.

How We Test and Score

We measure at 1080p/240 with a hardware lag tester and high-speed capture, then validate in real play. We also log VRR/ALLM behavior and whether motion processing is truly off. For foundations, see Projector Input Lag, Tested & Explained (https://aixprojector.com/guide-projector-input-lag-explained/) and VRR basics from RTINGS (https://www.rtings.com/monitor/learn/variable-refresh-rate-vrr).

Scoring (100 pts):

• Input Lag 40% – 1080p/240 end-to-end

• Motion 20% – blur, overdrive artifacts

• Stability 15% – VRR behavior, frame pacing

• Practicality 15% – throw, noise, heat

• Ports & Platform 10% – HDMI, eARC, app support

Setup Checklist

1. Signal: Force 1080p/240; cap FPS slightly below 240 for stable pacing.

2. Processing: Disable MEMC, noise reduction, dynamic contrast.

3. Mode: Use Game/Low-Lag; enable ALLM/VRR if supported.

4. Throw: Prefer short-throw to avoid shadows; see Short-Throw Guide (https://aixprojector.com/guide-best-short-throw-projectors/).

5. Audio: Use eARC passthrough to a soundbar/AVR to minimize delay.

6. Room: Control ambient light; an ALR screen helps clarity: ALR Screens (https://aixprojector.com/guide-alr-screens/).

Buying Tips

• HDMI bandwidth: 1080p/240 often runs on HDMI 2.0b; HDMI 2.1 isn’t mandatory here.

• VRR: Nice-to-have; it smooths spikes but doesn’t replace low baseline lag.

• Cooling & noise: High refresh can push fans; give the chassis breathing room.

• Throw math: Don’t rely on keystone; place correctly for sharpness and latency.

• Compare paths: For living-room big screen, also read UST vs Short-Throw (https://aixprojector.com/guide-ust-vs-short-throw/).

FAQ

Do projectors really do 240Hz?
Yes, at 1080p on supported models. Turn off motion processing to keep latency down.

Is 240Hz better than 4K/120?
For shooters and rhythm games, yes. For cinematic games, 4K/60 is fine.

Do I need HDMI 2.1 for 240Hz?
Usually no. 1080p/240 works on HDMI 2.0b. Check the spec sheet.

What input lag is acceptable?
Aim ≤ 8–16 ms for esports. ≤ 33 ms is fine for casual play.

Will VRR fix high lag?
No. VRR smooths frame-time but doesn’t lower a high baseline.
