BZBGear BG-8K-HS21AR 2x1 8K HDMI Switcher with RS-232 and Gain Control
The BG-8K-HS21AR switches two 8K sources to one display at up to 8K60 4:2:0 12-bit, 8K30 4:4:4 12-bit and 4K120 4:4:4 12-bit, with HDCP 2.3 and no measurable added latency on either audio or video.
It is the installed-system version of the HS21A: digital and analog audio de-embedding with gain control on the analog output, RS-232 and wideband IR for control, and a built-in HDMI signal generator so an installer can prove the display and the cable before the source arrives.
