Thunderbolt3 not using GPU

[mikeywhelan]

Hey guys,
I have a 144hz monitor and I'm connected to it via display port from my laptop. However when I connect to it, it only outputs from my integrated graphics. I've tried to change it on Nvidia control panel and stuff but I can't seem to get any results.

Thanks guys!

If that is how the laptop is configured, then there is not much you can do about it. This is the case with most TB3/USB-C ports on laptops, the DisplayPort lanes are provided from the CPU's integrated graphics rather than the dedicated GPU.

Damn that sucks. Not sure why they even supply such a nice GPU without the possibility of even using it to the full extent.
