LG 34UM68 - Refresh rate overclocking 'Out of Range'

Was just playing around with how far I could push the refresh rate on my LG 34UM68 when I managed an absolutely insane and seemingly stable 110 Hz (the monitor is rated to 75Hz with Freesync, but I struggle to get it to natively run past 60Hz thanks to my GTX 980). The only problem is anywhere past 80Hz causes a massive 'Out of Range' message to be displayed, which is an overlay from the monitor itself (unable to screenshot from within Windows).

 

Is anyone aware of a tool to remove this overlay, or should I stop looking for one as this is damaging my monitor? haha

 

Thanks

how do you know your monitor can hit 110Hz?

 

This is a limit put on by LG on the hardware of the monitor. In other words, even if there is a fix, you need to open up the monitor and mod the hardware.

First tip off is that mouse movement in Windows is butter smooth haha

Also used the UFO test and it seems to confirm that what I did in the Nvidia Control Panel did actually work.

 

Ok, assumed it might just be a driver based thing that someone might have successfully modified to remove the warning.

Any luck with this? @MayorPotatoSalad ... I want to get rid of the overlay as well because my 34UC88 appears to have a stable 90hz overclock.
