Black screen after PC goes to sleep/suspend

I get a black screen when i wake up my PC from suspend/sleep.
I have 2 monitors and am able to move my mouse to my 2nd monitor not my main montior,
Im able to fix this by unplugging my displayport cable from my main monitor and then replug it , main monitor has no signal when this happends,

Don't have this issue on Windows . i always have no signal on arch iso aswel at the tty terminal after grub grub etc does show on my mian monitor but after it goes no signal aswel,

here is a video of my 2nd monitor when booting from arch iso

Re: Black screen after PC goes to sleep/suspend

A video of a dead screen is maybe less helpful than some information on the involved hardware and software.
The general problem is that the output likely unregisters and an overzealous daemon deactivates it but continues too late to catch the handshake when the monitor shows up again.

Wrt "Don't have this issue on Windows", 3rd link below. Mandatory.
Disable it (it's NOT the BIOS setting!) and reboot windows and linux twice for voodo reasons.
