When overclocking a laptop monitor, what is the bottleneck, is it the GPU or the monitors?

So most what I've seen on monitor overclocking indicates that it's done through your GPUs control panel. This being a big factor as why integrated graphics laptops cannot overclock well. I'd like to know if the inclusion of external GPU changes this dynamic in any way. I think an external GPU will enable you to install the Nvidia control panel. Does this let you overclock your monitor too?

There's a control panel for Nvidia, AMD, and Intel. I think they all let you create custom resolutions.

For Intel, it's called Intel Graphics Command Center which replaces the older Intel Graphics Control Panel. I think you can install them both (start with the old one first).

Then there's CRU which lets you edit the EDID of your display

Yeah +1 for CRU even on my Ivy bridge iGPU where the intel graphics control panel is locked down and there's no framerate options, CRU still works and I can install the EDID through the exported .exe. I think its pretty funny that my old macbook panel can do 120Hz (actually 119.97 but close enough)

@nu_ninja, Did you have to downgrade your driver using the "Intel Graphics Driver for Windows [15.40]" described in ToastyX's post? I have a graphics driver version 20.XX (so higher) and I don't think it'll let me downgrade without messing up a few things. I've never uninstalled/downgraded my drive before.

No I have a 3rd gen CPU so not doing anything with the driver, I'm following the alternative method a little bit further down in the post
