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 X500i and the Nebula Cosmos 4K SE made our Top 5 Projectors for PS5, at #3 and #4. The pick for small rooms: its 0.69-0.83 short-throw lens fills 100 inches from about 5-6.5 ft, where the Optoma UHD38x needs roughly twice the distance. It shares the X3100i's 4LED engine, Android TV and fast modes (about 16 ms at 4K/60, 8 ms at 1440p/120), and Expert Reviews found no noticeable lag on PS5. It ranks third because its 2,200 lumens trail the X3100i by 1,100 and the UHD38x by 1,800, at a higher price than the Optoma. The best pick when films matter as much as games: it is the only projector here with Dolby Vision and built-in Google TV with licensed Netflix, and its automatic focus, keystone and screen fit make setup quicker than any BenQ or Optoma here. It ranks fourth because TechRadar measured 18.5 ms only in Game Mode Extreme (35 ms in standard game mode), it has no 120Hz mode, and its 1,800 lumens are the lowest in the list.
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 X500i totals 8.6 out of 10 and the Nebula Cosmos 4K SE 7.8. The widest gap is Gaming Responsiveness, where the BenQ X500i scores 9.5 against 7 for the Nebula Cosmos 4K SE: published input lag at 4K/60Hz (the PS5's Fidelity mode) first, then support and lag for the console's 1080p/120Hz Performance mode. Brightness also separates them: 7.5 for the BenQ X500i versus 6.5 for the Nebula Cosmos 4K SE. The Nebula Cosmos 4K SE claws back ground on Value.
