HDMI Port Stopped Working

[DenaliXL19]

Anyone else have problems with their HDMI port stop working?
Mine started to intermittently not work, and then completely stopped.
It's a 2019 with 20k miles so I'm hoping they cover this under warranty.

Did you ever figure this out? Trying to set up a Roku in my 2018 Tahoe (RSE) and it's not working. Don't know if it's the HDMI port, or have to troubleshoot the Roku settings (as seen in various posts). I will try messing with it more tomorrow, but just curious if you figured out the HDMI in case I have to go that route.
