External Monitor (HDMI) not detected, ASUSTeK UX490UAR, LM 20.1

Post by SikMuse »

I'm experiencing the exact same issue and same scenario : recently upgraded Mint to 20.1 from 19.3 and my HDMI stopped being detected. I've tried restarting, changing the cable, and changing the monitor - it works on other laptops but not this environment any more. :(

Are you running the most recent BIOS/UEFI available for your laptop? Sometimes that can make a difference on how the port works.
