    The laptop that I have uses an LG LP173WF4-SPD1 which uses eDP.

    Other variant of my laptop like the ASUS G751JY uses the exact same display with the exact same connector and people were able to overclock the LCD easily to 100Hz without any issues.

    My main rig uses a BenQ XL2420Z with is a 1080p 144Hz monitor and going back to 60Hz is very distracting to me.

    The problem with my laptop is it uses NVIDIA Optimus which relies on the Intel Graphics to change setting like custom resolution.

    I tried overclocking the laptop LCD through Intel Custom Resolution but even at just 65Hz it would say it exceeds the maximum bandwidth capacity. Other people with default high resolution (3200x1800) have the same issue when they try to create a custom resolution even with lower resolution than their panel HERE. I tried googling a pixel clock patcher for Intel Graphics but to my dismay the only available pixel patcher is for MAC HERE and HERE.

    Is there a similar program for windows to remove the pixel clock limitation for Intel Graphics?

    To my knowledge if you have Optimus everything is routed through the igpu and you´re stuck with 60 Hz. If you do find a way please share it here.

    Not sure, only way is if you put the LCD in a non-optimus laptop and program the EDID.
