Verdict

The Optoma UHD35x is a high-performance DLP projector featuring true 4K UHD resolution with 8.3 million addressable pixels and a bright 3,600 lumens output, making it suitable for lights-on viewing. Primarily designed for gaming and home entertainment, it boasts an exceptional 240Hz refresh rate at 1080p and a lightning-fast input lag of just 4.2ms (16ms for 4K at 60Hz), alongside HDR10 and HLG support for enhanced color depth and a 1,000,000:1 dynamic contrast ratio. Key advantages include its impressive gaming responsiveness, high brightness for ambient light conditions, and Full 3D compatibility. However, notable drawbacks include limited placement flexibility due to a narrow 1.1x manual zoom and the absence of vertical lens shift, potential fan noise reaching up to 28dB, and reports of inconsistent out-of-the-box color accuracy and long-term reliability issues with the UHD series.
