One monitor going black after logoff/logon

Dual monitors, when pc goes idle and I login again, one monitor (DP3) starts going black. Part when I move cursor to it, part randomly, and goes fully black eventually. If I reconnect the cable it starts working fine again, but at first shows an empty workspace.

Also I have login screen on both screens.

Any ideas?

# for 2560x1440
monitor = DP-3, 2560x1440@144, 0x0, 1, vrr, 1

monitor = DP-2, 1920x1080@99.93, -1920x0, 1

monitor = , preferred, auto, 1

workspace = 1, monitor:DP-2, default=true
workspace = 2, monitor:DP-3, default=true
workspace = 3, monitor:DP-3 
workspace = 4, monitor:DP-2

Give an HDMI cable a test instead of display port. Be sure the HDMI cable is at least 4K capable.

Never had an Issue on Windows though.
