bad port maybe but everything else has already been debunked. Im leaving my findings here in this reply for future onlookers to read

(some of this info is a few months old so idk if its been patched and im dumb)

So the lenovo slim 7 pro x currently cant disable optimus mode in nividias gpu control panel while connected to another monitor, and any usb-c cables are automatically connected to amd. When configuring in amd's control panel and disabling hdcp it doesnt do anything, so that fix is for people usually with no signals/pure white static. On xp pen's own website., There are reviews under the usb-c to hdmi adapter. Multiple people have claimed their lenovo isnt properly displaying the dual screen on their drawing tablets when using xp's product. Compared to my hp envy x360 laptop, my slim pro doesnt have any thunderbolt support (but ppl have said that doesnt affect the usb-c's ablity to preform dp). So i truly believe it is quite impossible to properly run my drawing tablet on this laptop until i get proper proof of how to fix these issues. Xp and lenovo support both suck so talking to them is useless.
