Second monitor turns on and off

I have just installed the OS over the weekend and noticed a wierd bug, the second monitor keeps going black for a few seconds almost after every action I do on the first monitor, it could be anything, turning on an app, typing a command in terminal, anything.

one fix that sometimes works is to disable and then enable the display.

However once the PC is locked and then I re-login the problem comes back

bump??? please its making me lose my mind

Hi!

Have you tried to change the adaptive sync to “never” on both monitors and apply? (system settings → display & monitor, if you want VRR try always instead (if you have automatic)

You could also try to lower from 165Hz to 144Hz and see if that removes the issue.
