10.15.6 - Non-functional with 5.2.4

I have two MacBooks - Air and Pro - hooked to two Dell D6000's.

The Pro was running 10.15.5 and working fine, even in clamshell. It has one monitor hooked to it using HDMI to HDMI.

Then mysteriously it started playing up today. It is hooked to an LG widescreen with a resolution of 2560x1440 75Hz. DisplayLink insisted on setting resolution to 3840x2160.

I tried everything and it didn't work so I finally upgraded to 10.15.6. Clamshell no longer works - it displays for about 30 seconds and then goes blank, plays some sort of system sound and then comes back on and repeats this. Resolution still stuck at 3840x2160.

So I downloaded the SwitchResX utility and forced it to native resolution.

The MacBook Air has not worked in clamshell since I installed the 5.2.4 driver.

Fun!
