Yes — any projector with HDMI works. The experience depends on three specs:

• Input lag: under 16ms in game mode is excellent; under 30ms is playable; over 30ms feels laggy
• Resolution/refresh: 4K/60Hz for cinematic games, or 1080p/120Hz for competitive play
• Brightness: 2,500+ lumens if you game with any lights on

A dedicated gaming projector like the BenQ TK700 checks all three. A generic home theater projector without game mode will technically work but feel sluggish in anything fast-paced.

It depends on what you play and your budget:

• Mostly multiplayer/competitive: a 1080p/120Hz projector ($550-800) is the better buy — PS5 Performance mode outputs 1080p at high frame rates anyway, so a 4K panel adds nothing in those games
• Mostly single-player: 4K ($950-1,700) is worth it — Fidelity mode at 4K on a 120-inch screen is the whole reason to game on a projector
• Mixed: a 4K gaming projector handles both modes; get one with sub-20ms game-mode lag

Viewing distance matters: from 10-12 feet on a 100-inch screen, 1080p still looks good. Under 10 feet or above 120 inches, 4K becomes clearly visible.

Almost never, and it's the most common overspend mistake. 4K/120Hz requires full 48Gbps HDMI 2.1 bandwidth; the handful of projectors that support it cost several thousand dollars. VRR (variable refresh rate) support is rarer still.

What projectors actually deliver with PS5: 4K at 60Hz and 1080p at 120Hz. Between those two modes you cover every PS5 game well.

If 4K/120 + VRR is non-negotiable for you, a 65-77" gaming TV is the right tool. If a 120-inch image is the goal, the projector trade-off is worth it — that immersion doesn't exist at any TV price.

Yes — HDR10 works on HDR-compatible projectors (BenQ TK700/TK710, Epson Home Cinema 3800, most 4K models). Two caveats:

• Projector HDR is much dimmer than TV HDR — projectors can't hit 1,000-nit highlights, so HDR looks subtler
• In rooms with ambient light, HDR can look darker and flatter than SDR — try both and keep what looks better

Set PS5 HDR to "On When Supported" and calibrate with the PS5's built-in HDR setup while the room is at your normal gaming brightness.

100-120 inches is the sweet spot for most rooms:

• 100": needs ~8-11 ft throw distance (standard throw); comfortable from 10-14 ft seating
• 120": needs ~10-13 ft throw; where 4K starts clearly beating 1080p
• Small room? A short-throw model like the BenQ TH671ST throws 100" from ~5 ft

HUD-heavy competitive games (Fortnite, Warzone) can feel overwhelming above 120" because UI elements land in your peripheral vision — another reason 100-120" is the practical ceiling for mixed gaming.
