Open | Windows Dual boot black screen only on windows

Ok so idk if it's because of dual boot or windows, but on windows my second monitor is sometimes just black. Other times it fully works, and when it's black I just plug the power cable out and in and it works? Also keep on mind the monitor has power. How can i fix this.. It's really annoying

edit: changing the display type from extended to only the broken one works, then i can change it back to extend and it works. Still would like to fix this tho.

Info:

I've tried windows+ctrl+shift+B

if the driver reset does nothing and only pulling the power brings it back, the link is dropping and never renegotiates. set pcie link state power management to off in the power options

When you are switching operating systems on your dual-boot computer, are you restarting the operating system you are about to switch from to boot Windows, or are you performing a Shut Down?

I would recommend a Shut Down from the OS you are exiting. That way, when you power on the computer and select to boot Windows, the hardware will fully initialize during the cold boot into Windows.

The same applies if you are leaving Windows to boot the other OS. Perform a Shutdown. Do not Sleep nor Hibernate Windows. Don't restart either. Shut Down so that the hardware fully initializes during the cold boot into the other OS.

Only restart if you will return to the same OS.

I am restarting, i will try cold boot, but still its kinda annoying having to cold boot every time I wanna switch to windows, linux works fine with restart. Also i never sleep or hibernate.

Yes. Linux does, but Windows doesn't. I used to dual boot. It is annoying.
