XL2420G can't recognize DisplayPort when G-Sync is off. Help!

[Raccatography]

My friend is having this problem. He can't use the other features like Blur Reduction because of this so he plays CSGO and Overwatch with G-Sync.

 

Has anyone solved this? He has the latest Nvidia drivers but he can't install the INF driver (from disk) of the monitor. However, his computer recognizes his monitor as XL2420G and not as PnP Generic shit.

If hes had to muck about with .inf files and other shit then hes probably screwed the drivers somewhere.

I'd start with running DDU in Safe Mode, and if problem persists then call us back in the morning.
