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 Optoma UHD38x and the BenQ TH575 made our Top 5 Projectors for PS5, at #2 (best value) and #5 (best budget). The best price for real 4K PS5 gaming: about $999 buys the same 16.7 ms 4K/60Hz lag as the X3100i, a 4.2 ms 1080p/240Hz mode, and 4,000 ANSI lumens, the brightest rating in this list. It ranks below the X3100i because it uses a lamp, has no lens shift or smart platform, and needs about 13 ft for a 120-inch image, and above the X500i because it is 1,800 lumens brighter for about $500 less. 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 Optoma UHD38x totals 8.7 out of 10 and the BenQ TH575 7.6. The widest gap is Gaming Responsiveness, where the Optoma UHD38x scores 9.5 against 7.5 for the BenQ TH575: published input lag at 4K/60Hz (the PS5's Fidelity mode) first, then support and lag for the console's 1080p/120Hz Performance mode. Picture Quality also separates them: 8.5 for the Optoma UHD38x versus 6.5 for the BenQ TH575.
On paper, the specifications that actually differ: Resolution: 4K UHD (3840 x 2160, DLP XPR) on the Optoma UHD38x versus 1080p (1920 x 1080, DLP) on the BenQ TH575; Brightness: 4,000 ANSI lumens on the Optoma UHD38x versus 3,800 ANSI lumens on the BenQ TH575; Light Source: Lamp (240W) on the Optoma UHD38x versus Lamp (210W) on the BenQ TH575; Light Source Life: 4,000 hours bright mode; up to 15,000 hours Dynamic on the Optoma UHD38x versus Up to 15,000 hours (eco modes) on the BenQ TH575; Input Lag (4K/60Hz): About 16.7 ms on the Optoma UHD38x versus N/A (no 4K input); 16.7 ms at 1080p/60Hz on the BenQ TH575; Fastest Game Mode: 1080p/240Hz at about 4.2 ms (Enhanced Gaming Mode) on the Optoma UHD38x versus 1080p/60Hz at about 16.7 ms on the BenQ TH575. They match on Smart Platform.
Check current pricing at the merchant links below. Owners praise the Optoma UHD38x for 4,000 ANSI lumens, the highest brightness rating here, so it copes best with some room light and 16.7 ms at 4K/60Hz and 4.2 ms at 1080p/240Hz in Enhanced Gaming Mode, matching projectors that cost far more; the most common complaint is lamp light source, rated 4,000 hours in bright mode (up to 15,000 in Dynamic/Eco), so a replacement lamp is a running cost. Owners praise the BenQ TH575 for about $749, the cheapest pick here and less than half the price of the X3100i and 3,800 ANSI lumens, second only to the Optoma UHD38x in this list; the most common complaint is 1080p/60Hz only: no 4K input and no 120Hz mode, so the PS5 runs at 1080p.
