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 Nebula Cosmos 4K SE and the BenQ TH575 made our Top 5 Projectors for PS5, at #4 and #5 (best budget). 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. 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 Nebula Cosmos 4K SE totals 7.8 out of 10 and the BenQ TH575 7.6. The widest gap is Smart Features & Audio, where the Nebula Cosmos 4K SE scores 9 against 5 for the BenQ TH575: built-in streaming platform and licensed apps, casting, eARC passthrough and the usefulness of the built-in speakers. Brightness also separates them: 9 for the BenQ TH575 versus 6.5 for the Nebula Cosmos 4K SE. The BenQ TH575 claws back ground on Value and Gaming Responsiveness.
