Monitor 4K Scaling issue?

[mid_gen]

That's windows sleep for you
Mine randomly came out of sleep for no apparent reason

Instead of turning off or putting my monitor to sleep (oled)
Now I just use a plain black wallpaper
And i have automatic hide desktop icons enabled
So a pure black screen which should mean no pixels lit up
Therefore no burn in worries
Not a perfect solution as still power to the monitor
Even if not using it
But the random coming out of sleep got very annoying
