Optoma’s UHD55 projector offers 4K output and 3,600 lumens for $1,799

Optoma has introduced a new lamp-based DLP projector that offers 4K output and a peak brightness of 3,600 lumens. With a claimed contrast ratio of 1,200,000:1, the company UHD55 Suitable for daytime use as long as there is no natural or artificial light falling directly onto your wall or projector screen. There is no mention of Dolby Vision support, but it offers HDR and HLG compatibility. With the shutter activated, the UHD55 covers 97 percent of the DCI-P3 wide color gamut.

It also comes with 3D support in side-by-side, top and bottom, and frame sequential modes. If you use the projector’s built-in Dynamic Black mode, you can expect up to 15,000 hours of use from the included bulb. Provided you have room to place it, the UHD55 can project a 300-inch image.

A dedicated gaming mode limits input lag to under 16 milliseconds at 4K, but the UHD55 is more of a PC gaming projector than a console. It does not have an HDMI 2.1 port, which limits its ability to refresh a 4K image at 60Hz. However, when connected to a PC, the UHD55’s two HDMI 2.0 ports with HDCP 2.0 support a 240Hz refresh rate at 1080p. Input lag is also reduced to 4 milliseconds or less. Other notable features include Amazon Alexa and Google Assistant compatibility, and built-in IFTTT support. The UHD55 can be purchased for $1,799 starting today.
