Q1: I can't get the HDMI port to work. What should I do?
A: 1) Confirm if the connected USB C port of your device supports DP1.4 Alt Mode
2) Confirm if HDMI cable is HDMI 2.0 version or above
3) Try a different computer and HDMI cable to see if the issue still persists
4) Plug your HDMI cable directly into your device and see if you get a stable connection. If you can't get a stable connection, then the problem is with your HDMI cable
5) Verify that your monitor is configured to the correct input (HDMI)
