How they differ in real use
Built from our projectors for ps5 scoring, each product's published specifications, and verified owner feedback — not hands-on testing.
Both the BenQ X3100i and the BenQ TH575 made our Top 5 Projectors for PS5, at #1 (best overall) and #5 (best budget). The most complete PS5 projector: it matches the Optoma UHD38x's 16.7 ms at 4K/60Hz and adds an 8 ms 1080p/1440p 120Hz mode, while its 4LED light source (20,000 hours) removes the lamp replacements the UHD38x and TH575 need. Its 1.3x zoom and vertical lens shift make it far easier to place than the Optoma, and it is 1,100 lumens brighter than the BenQ X500i. RTINGS scored it 8.1 for gaming. It costs about $800 more than the UHD38x, which is why the Optoma takes Value. The cheapest credible big-screen PS5 setup at about $749: 3,800 ANSI lumens (brighter than every pick except the UHD38x) and 16.7 ms at 1080p/60Hz, which RTINGS rated decent for casual gaming. It ranks last because it is the only 1080p projector here, with no 4K or 120Hz input, washed-out HDR and no smart platform, where the Nebula Cosmos 4K SE adds 4K, Dolby Vision and Google TV for about $220 more.
We score projectors for ps5 on Gaming Responsiveness (25%), Picture Quality (20%), Brightness (15%), Room Fit & Setup (15%), Smart Features & Audio (10%) and Value (15%). On that basis the BenQ X3100i totals 8.9 out of 10 and the BenQ TH575 7.6. The widest gap is Picture Quality, where the BenQ X3100i scores 9.5 against 6.5 for the BenQ TH575: resolution, HDR format support and handling, and contrast as reported by independent reviewers such as RTINGS and TechRadar. Gaming Responsiveness also separates them: 9.5 for the BenQ X3100i versus 7.5 for the BenQ TH575. The BenQ TH575 claws back ground on Value.

Owners praise the BenQ X3100i for fast in every PS5 mode: about 16.7 ms at 4K/60Hz and about 8 ms at 1080p/120Hz (BenQ; consistent with PCGamesN and Projector Reviews) and 3,300 ANSI lumens from a 4LED light source rated for 20,000 hours, so there is no lamp to replace; the most common complaint is contrast in near-dark scenes trails dedicated home-theater projectors (RTINGS).
