LG - 32GN600 Making a loud beep when running Heaven

[Aestolia]

Hi I was wondering if anyone had experienced something similar to this. 

 

I just managed to get home with my newly secured GPU and wanted to run a bench, so I loaded up Heaven 4.0 - When running at 2560 x 1440 the LG monitor emits a loud constant beep. The noise stops when I drop the resolution. I am fairly certain it's the monitor making the sound not the PC, as I've put myself between the PC and the monitors and the sound definitely comes from where the monitors are. 

 

The monitor is supposed to do 2560x1440 @165, but I've tried at both 165 and 144 refresh rates and the sound persists, but only at 2560x1440. I've tried with FreeSync / Gsync Compatible on and off as well (it actually seems to be worse when turned off)

 

Any insight would be Greatly appreciated.

Nevermind... it wasn't the monitor.. it was my UPS crying in pain trying to power my new GPU. (my UPS is right beside the monitors which is why I though it was coming from them.)
