This resolution compatibility has been tested with a limited number of monitors and computers, hence we cannot guarantee that every monitor and computer combination will work with the expected resolution above. For any additional questions, please contact your Logitech representative.
Monitor is set at 4K but does not look 4K during a video call
Check that your HDR setting is off, outside of active video streaming.
macOS with HDR mode selected, screen looks pixelated when NOT watching a movie.
When you do not watch an HDR movie, please untick HDR mode, as it may provide lower resolution.

Logi Dock not detected with Mac OS Ventura 13.0
Mac OS Ventura (13.0) may have a dialog pop up “Allow accessory to connect” when Logi Dock is connected via Upstream port. If you “allow” it, then it will be detected as expected. However if you hit "Don't Allow" the following is observed:
Monitors continue to work.
Logi Tune does not detect Logi Dock or any connected peripherals.
None of the USB peripherals connected to Logi Dock work.
In order to resolve this issue, please go into Settings -> Privacy and Security and change the selection again from the list to get system dialog “allow accessory to connect” to come up.
