(MacBook Air M1, two Philips 328p6vu 4K displays)

With macOS 11.3.1 and DL1.4 I could use these monitors with 4K at 60Hz (i-tec USB 3.0 / USB-C Dual 4K DP Video Adapter [PN: U3DUAL4KDP]).
But after updating to macOS 11.4 ...1920x1080 is the max. resolution available.

My monitors were only showing 1920x1080, but this link helped fix that. Key was holding down the option (alt) key when selecting the 'scaled' option.

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.
