Uses this item for our second 1920x1080 display - on Mac Pro 2019 Rack - 16 Core - Radeon Pro W5700X - Big Sur. When used with this Cal DIGIT USB-C to HDMI converter, after a typical reboot, the desktop image for the main display connected directly to the computer will revert to the default desktop image. The desktop image for the monitor connected to this device remains selected. So, out of curiosity, we switched this adapter from Apple USB C to HDMI and everything works great. Not sure what it is, possible Big Sur compatibility? either way it doesn't work properly.
