Custom Resolution Utility (CRU)

[CorneliousJD]

Hi all, I'm having some trouble!

Long story short, new DisplayPort monitor keeps being disconnected from the system when it goes into standby, and I wanted to override the EDID so Windows just thinks it is always connected and I can always render out to it (so it stops messing up my windows/icons constantly!!!)

I could honestly use some help on how to do that in the first place, but my first hiccup is as follows.

It's a Samsung Odysssey G9 (5120x1440)
Every time I try to enter 5120 into the resolution box it shows in red and doesn't let me save it.

Any help is appreciated. Thanks in advance!
