Custom Resolution Utility (CRU)

[DethCubeLord]

Before I begin my question, I must thank you wholeheartedly for your time and effort that you spent behind this

I am using the HP ProBook 450 G3, 17" 1366x768 TN, i5-6200u, Intel HD Graphics 520 + AMD Radeon R7 M340 variant. I have managed to overclock it to 79 Hz successfully, but as soon as I cross this threshold, the monitor produces a tad flickering and very distorted and discoloured image (although the refresh rate seems to increase). I tried using the reduced LCD option too, but to no avail ... Does this mean that I've kinda hit the limit my display can handle? If not, could you please beacon me to what I should do to further push the frames?

And once again, thanks for supporting this for 7 years!
