Hey guys,
I’m having problems again with my second monitor. I had a similar problem with the last kde plasma update which was eventually fixed. The problem was slightly different tho. Last time the second monitor was shown before login and a profile reset could solve the problem. This time the second monitor gets no input all the time.
I run a Lenovo Ideapad 5 Pro 14ACN6 plugged into a Lenovo Universal USB-C . To that dock is connected a LG UltraGear 34GN850-B and a ASUS MG279Q as a second external monitor. Both are connected via display port. The system is up to date.
The same setup works fine with a Thinkpad t14 (4850H Edition) with Windows 10 and also with my gaming rig with Windows 11.
