True 4K UHD projection for home cinema and gaming

The Optoma UHD55 delivers true 4K UHD resolution with 8.3 million distinct addressable on-screen pixels for double the detail of 4K Pro UHD. Its 3600 lumens brightness supports lights-on viewing in living rooms or media spaces. The 97% DCI-P3 color gamut coverage produces cinematic color accuracy for movies and HDR content. This projector suits enthusiasts who want high-resolution big-screen entertainment without a dedicated dark room.

Flexible installation

A large 1.3x zoom lens allows versatile placement distances without moving furniture. Four-corner geometric correction adjusts the image shape when the projector cannot sit perfectly centred. Enhanced Gaming Mode cuts input lag to 4ms at 1080p 240 Hz for competitive play, or 15ms at 4K UHD for detailed single-player sessions. Built-in media player and USB playback let you watch files directly without a laptop. Voice control via Alexa or Google Assistant and IFTTT support add smart-home convenience.

Check room lighting, throw distance

Verify that 3600 lumens matches your ambient light conditions; very bright rooms may still wash out black levels. Measure the available throw range to confirm the 1.3x zoom covers your desired screen size from the mounting position. Ensure your content sources output HDR10 or HLG signals to use the four HDR picture modes and dynamic tone mapping. The built-in speaker is convenient for casual use but a separate audio system is recommended for cinematic sound.
