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

The new lamp-based projector from Optoma delivers 4K output and a peak brightness of 3,600 lumens. If there is no natural or artificial light falling on your wall or projection screen, the company says the UHD55 is suitable for daytime use. There is no mention of Dolby Vision support. The UHD55 covers 97 percent of the wide color range.

It has 3D support in side-by-side, top and bottom and frame sequential modes. If you use the built-in Dynamic Black mode, you can expect to get up to 15,000 hours of use from the included bulb. If you have enough space, the UHD55 can project a 300-inch image.

A dedicated gaming mode limits input lag to below 16 milliseconds at 4K, but the UHD55 is more of a PC gaming projector than a console one. The ability to refresh a 4K image at 60Hz is limited by the lack of an HDMI 2.1 port. The two HDMI 2.0 ports with HDCP 2.0 support a 480Hz refresh rate. The lag is reduced to less than 4 milliseconds. Notable features include compatibility with Amazon and Google Assistant. The UHD55 will be available for a price of $1,799.
