The Dell AW3821DW doesn’t seem to be compatible with the dock via HDMI. It only outputs a 30hz signal. I have a 16" Macbook Pro 2019 model running Big Sur 11.0.1 . When forcing the laptop to output 60hz in Display preferences, the screen doesn’t get a signal.
However, when using DisplayPort, everything works fine. I tried both HDMI outputs, 3 different cables (two HDMI 2.0 cables and one HDMI 2.1 cable), reset the hub multiple times and tried different ports on the Mac, tried both disabled and enabled graphics switching options to no avail.
The same cables and screen work just fine with my PC. Unfortunately, I can’t use the DP port in my current setup with the Hub so I need to find a solution to use the HDMI ports on this hub…
Any help would be appreciated! Working at 30hz isn’t ideal.
