Optoma UHD55 (2022)

A 3,600-lumen 4K UHD home-theater and gaming projector with both HDMI 2.0b inputs capped at 4K@60Hz — gaming highlights include a 4ms response at 1080p@240Hz. Unlike many projectors, it offers genuine audio flexibility: a 3.5mm analog input, an optical TOSLINK (S/PDIF) output for soundbars, plus a legacy VGA input and RJ-45 for network control. Two USB-A ports cover media playback and power. A 12V trigger and RS-232 jack handle screen and control automation.

Optoma’s 3,600-lumen 4K projector with dual HDMI 2.0b, optical S/PDIF out, VGA input, USB-A, and RJ-45 control.
