2 Monitors Detected, but only 1 displaying picture - Page 2

My problem was second monitor was recognised in System Prefs but black or no signal detected on second. I can't remember if mirroring 1 to 2 helped / worked given the number of things I've tried in hope of solution...!

I did however luckily solved the issue for me. I swapped places of my HDMI cables, and then it worked. I guess on of the cables are of an older version and wasn't compatible with the displaylink adapter.

I will try again with different HDMI cables.

I have a MBP M1 and just bought the Dell 6000 to run 3 external monitors

I can get 2 x DP>DP working but the DP>USB and/or DP>USBc wont work.

Does anyone know if this is a Monterey 12.3 problem with the Dell 6000 ports or with the Displaylink download?

My guess is its an Apple/Dell issue but any advice appreciated!
