Accidentaly punched monitor, and this happend.. How to fix it?

I would turn off and unplug the PC and monitor. Remove the HDMI cable and reinsert it.

Unplug the cable(s) connected to the GFX card and open your case, unplug your GFX card's PCIe cable(s) and then remove it from the slot. Put it back in. Put the cables back in their sockets.

I tried.. Its really not a cable thing, this mark will be forever, you can only see it when dekstop ir grey, Its just hit little bit too hard, and this monitor is really not old, just maybe 1 year old, because the same monitor was in the warranty. Sad life, maybe 2 years later i will change it :D
