Zenbook 2nd Screen Dark

Hi, I own an ASUS zenbook duo ux8406. My second screen has randomly stopped being automatically detected and seems to be turned off even when I detach my keyboard, however the touchscreen functionality of the second screen still seems to be working as a trackpad of sorts for my main display. Any chance I accidentally turned on a function for the second screen to become a trackpad? I have updated all display drivers, ran multiple diagnostics through MyASUS, and have gone through a hard restart.
