Optoma UHD38 (2021)

A bright true-4K UHD gaming projector with two HDMI 2.0 inputs (HDCP 2.2) tuned for low-latency play. It keeps a legacy VGA (D-Sub 15) input that accepts RGB or component YPbPr, handy for older sources. Audio routes out through either a 3.5mm jack or an Optical S/PDIF output (2-channel), and there's a 3.5mm audio input as well. A USB-A port supplies 1.5A for a streaming stick. Installation extras — an RS-232 control port, a 12V trigger for motorized screens, and the AC mains inlet — sit outside the everyday A/V cabling.

True 4K UHD gaming projector with dual HDMI 2.0, legacy VGA, 3.5mm audio in/out, Optical S/PDIF out, and a powered USB-A port.
