I have an M1 MBA and a Dell P3421WM connected to a CalDigit TB4 dock. Display is connected to the dock via a TB3 cable and the dock is connected to the M1 via a TB3 cable as well. Both USBC.
I run the display at 3440x1140 - however whenever the display sleeps (time varies) and I wake it, a lot of the time it defaults to 1920x1080. I have to open the M1, disconnect the dock cable, wait, reconnect the cable and close the lid. Now the resolution is correct.
Why does it do this? I have tried new cables as well, even switching to TB4. Nada.
