Sending the DisplayLink output zip file. Help!
My Mac M1 has:
1) Dell U3219Q <-- this one shows the 3840x2160 high resolution that I expect.
2) Dell P2715Q <-- this one shows only 1920x1080 for "More Space" where the text is too big!
I have a new Kensington SD4780P docking station.
Also, I could have sworn that when I first connected the 2nd Dell monitor that it looked right, then after a minute or two the displays went black for several seconds, and afterwards the 2nd Dell monitor was stuck at 1920x1080.
