Just got this issue after i put PC in 'sleep mode' as i always do, turned off monitor.

Turned monitor on, woke PC from sleep, now monitor cant go into 144Hz anymore its stuck on 120Hz max, Benq XL2420z.

When i watch the text on tl.net its sometimes blue sometimes black.

Example: "[ASL15] Afreeca Starleague To Start On Feb 14"

'freeca st art on' is dark blue, rest is black.

It seems to go in vertical stripes, if i do a printscreen and move it around in MSpaint the blue shifts to other text.

In BroodWar when watching a replay the red text of player name top right is extremely unsmooth, very pixelated.


Edit: Pulling out the DP cable and re-insert fixed it.

Can this issue relate to my screen having "no signal' sometimes if i dont start my PC in a specific order? I need to start the monitor first before the PC.

Edit2: The issue persist everytime i let PC into sleep mode i have to re-insert the DP cable.
