BenQ X3100i
BenQ's flagship 4K gaming projector: a 4LED, 0.65-inch DLP (XPR 4K) unit rated at 3,300 ANSI lumens, with a 1.3x zoom and vertical lens shift for flexible placement. For a PS5 it runs 4K/60Hz at about 16.7 ms and drops to roughly 8 ms at 1080p/120Hz, and RTINGS scored it 8.1 for gaming, calling it a great gaming projector if you value both speed and image quality. Android TV is included and the TreVolo speakers support eARC passthrough. Its weak spot is contrast in near-dark scenes, and it is the most expensive pick here.

Our Verdict
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.

Alternatives to Consider
Optoma UHD38x
Optoma
The long-running value pick for console gaming: a 4K (XPR) DLP lamp projector rated at 4,000 ANSI lumens, the brightest in this list, with 16.7 ms input lag at 4K/60Hz and an Enhanced Gaming Mode that reaches 4.2 ms at 1080p/240Hz. Retail and review sources consistently cite it as a strong PS5 match because it handles both the console's 4K/60 and 1080p/120 output. At about $999 it delivers the same 4K/60 lag as the BenQ X3100i for roughly $800 less; the trade-offs are a lamp that needs replacing, no built-in streaming apps and a long throw distance.
BenQ X500i
BenQ
The short-throw version of BenQ's gaming formula: a 4K (XPR) 4LED DLP projector rated at 2,200 ANSI lumens whose 0.69–0.83 throw ratio fills a 100-inch screen from about 5 to 6.5 feet, so it fits bedrooms and apartments where a long-throw projector cannot. BenQ quotes about 16 ms at 4K/60Hz and 8 ms at 1440p/120Hz, RTINGS scored it 7.7 for gaming, and Expert Reviews reported no noticeable lag playing 4K/60 PS5 games. It includes Android TV and the same TreVolo speakers as the X3100i, but it is 1,100 lumens dimmer.
Nebula Cosmos 4K SE
Nebula (Anker)
The movie-first, set-and-forget option for a PS5: a 4K projector with Anker's HybridBeam LED-plus-laser light rated at 1,800 ANSI lumens, Dolby Vision, Google TV with licensed Netflix built in, and automatic focus, keystone, screen-fit and obstacle avoidance. A carry handle makes it easy to move between rooms. For gaming it is merely adequate: TechRadar measured 18.5 ms in Game Mode Extreme but 35 ms in the standard game mode, and it is the dimmest projector in this list.
BenQ TH575
BenQ
The budget way to put a PS5 on a 100-inch screen: a 1080p DLP lamp projector rated at 3,800 ANSI lumens, with 16.7 ms input lag at 1080p/60Hz in its Enhanced Game Mode and a 15,000:1 contrast rating. RTINGS called it decent for casual 1080p gaming and noted its contrast gives games decent depth in a dark room. The compromises are real: it cannot accept 4K or 120Hz signals, HDR looks washed out, colors are muted out of the box, and there is no smart platform.
