■ The catch — co-equal billing, always
Its 1ms input lag is only manufacturer-stated. Independent testers have validated the BenQ X3100i's 4.2ms; XGIMI's 1ms figure hasn't been confirmed the same way. For a competitive FPS player the validated number is the safer bet — for family and casual play, it's a non-issue.
Dealbreaker? Runner-up №1 — the BenQ X3100i — has independently-validated 4.2ms input lag ↓

Traps — this verdict avoids
Why the XGIMI Horizon 20 Pro is right for you
It avoids every trap below — and for family of 4, no cap, it is the pick because it delivers:
The 4ms is a 1080p number
The headline low input lag exists only at 1080p/240Hz. Switch to native 4K/60Hz and real-world lag jumps 12–20ms higher. Competitive players game at 1080p on these; 4K is for slower single-player titles.
'4K' is usually pixel-shift
Most DLP gaming projectors here use a 1080p or 1440p chip pixel-shifted (XPR/e-shift) to 4K — not native 3840×2160. Up close the difference from a native-4K TV is visible.
Lamp models cost you a bulb
Lamp-based projectors (ViewSonic PX749-4K, Optoma UHD38x) need a new bulb every 3,000–5,000 hours at ~$100–250. Laser engines run 20,000–30,000 hours bulb-free.
