force 120/144 hz on my laptop

[WhyThereIsAPieOverHead]

Yesterday i bought a laptop 

msi gf63 thin 9rcx

its screen is originally 60 hz 

and i overclocked it to 100 hz but in it is not showing 1001 or above refresh rates

even though i have set a 120 hz in Custom Resolution utility

can i force set refesh rate if yes , how

in custom rez you can even set 240hz, but it will not run over the factory refresh rate, maybe slitght overclock would allow for something like 70hz, but nothing higher, definitly not 120hz

With all due respect, you are a madman if you think you can get 120hz out of a 60hz display.

You can maybe raise it a little bit (I am surprised you even got 100hz) but overall your screen is designed to work at 60hz and ideally you should leave it at that.

It appears that there is a version of your laptop with a 120hz panel.

If you have the 120hz panel, you just need to switch the refresh to 120hz as Windows will default to 60hz.

Here is how to change the refresh rate in Windows 10:

yeah, but you can't phisicly run the display at those refreshrates.

If it's not in Windows display settings then your display doesn't support it.

No, you can not push it that far. Maybe 10tps or so - but better to just leave it at 60hz, as your panel is 60hz

I'm stunned if it actually got to 100hz in the first place.

There's a far greater difference going from 60hz to 100hz than 100hz to 144hz... the more refresh rate you have the narrow is the frametimes until it reaches a point it's just so narrow it no longer makes a sensible difference.

100hz just looked like 144 hz in my eyes

i compared my laptop with my cousins ausus rog scar ii

except 100hz ghosted more

Your case it's ghosting likely because the screen has a higher GTG lag, which is understandable since it was meant to only drive 60hz.

 

Ghosting is not an effect of refresh rate alone but rather depended on GTG timings, to avoid ghosting you usually need 5ms or lower at 144hz, thing is you can't really trust manufacturers when they say "1ms GTG!" because it's really not always the case:

 

All these monitors have either 1ms or 5ms GTG response time on their marketing but the reality as we can see here is all over the place, the slower GTG the longer it takes a single pixel to switch it's colour entirely and when you've a high refresh rate where it's expected to change its colour very fast it might not keep up causing the ghosting effect...

 

Higher refresh rate won't eliminate ghosting only a lower GTG response time, on the example above that Viotek 144hz screen has more ghosting than the 95hz Pixio screen.
