Big-Screen Gaming: Low Lag, High Refresh, 4K Ready
A gaming projector turns a wall into a 100-inch-plus display, but for gaming the picture matters less than the timing. The specs that decide whether a projector plays well are input lag (aim for under 20ms for competitive play, under 40ms for everything else), refresh rate (120Hz or higher at 1080p, some models reaching 240Hz), resolution (Full HD or native/pixel-shift 4K), and brightness in ANSI lumens for your room. HDMI 2.1 with VRR and ALLM matters most for PS5 and Xbox Series X owners who want 4K at 120Hz. Compare BenQ, Optoma, Epson, XGIMI and ViewSonic models below and match the projector to your room, screen size and console or PC.
