Optoma UHD38x
The best value 4K projector — true 4K, 4,000 lumens, and 240Hz gaming support at a competitive price.
Our Review
The Optoma UHD38x delivers flagship specs at a mid-range price. True 4K UHD resolution with 4,000 lumens means a bright, sharp image even in well-lit rooms — the brightest in this roundup. 240Hz refresh rate support with 4.2ms input lag at 1080p makes it genuinely competitive for gaming. The DLP chip with 8.3 million on-screen pixels produces razor-sharp detail, and the 1.1–1.3x zoom provides placement flexibility. It's the best spec-for-dollar 4K projector available.
