You can note your issue below here
After my old monitor packed up recently, I installed a shiny new Dell Alienware AW2524F monitor, which has a maximum refresh rate of 500Hz.
All went well initially, and I have tried out a couple of the higher refresh rates (360Hz and 480Hz) which seemed to work fine with my GPU and Plasma 6 desktop. However, I have noticed that after I switch off my monitor but leave the PC running I cannot get the desktop to resume.
When I switch the monitor back on I get a 'no signal' message and the screen is blank. If I Ctrl-Alt-F1 I can get a terminal at 60Hz. I can then switch back to the desktop via Ctrl-Alt-F2 where I only see a mouse cursor and black screen but the desktop has seemingly crashed. If I Ctrl-Alt-Backspace I get get back to the log-in screen.
Power-related settings are all disabled.
I am guessing that something is wrong with the signal when I switch the monitor back on, but can anyone help me with this problem? Let me know if you need any more information.
Cheers!
There are a lot of roccateventhandler entries, of which I've deleted most. My keyboard and mouse function fine so I'm not sure what this error actually means.
Any help would be much appreciated.
