Monitor overclocking

[Ebony Falcon]

Hi friends, I have successfully oced some of my 1080p monitors from 60 to 80ish

but my main monitor is a Xb270hu 1440p 144hz monitor

So I can oc it at super low resolutions such as 800x600 to 190fps 

 

but when I try to oc at 1440p all I get is 1 FPS lol 

 

could it be my DisplayPort cable ? As i don’t no if it’s DisplayPort 1.1 1.2 1.3 or 1.4 and I know some of them don’t allow over 144hz 

could this be the case ?

This may be useless.

 

My memory (which is very old) is to overclock a monitor there actually has to be a part missing called an “ac”. No idea what it is.
