Update = After completing troubleshooting, a DELL-Cares agent setup a part replacement.
Hello, approximately one week after I am not sure what exact UEFI or OS update, the two left USB-C ports stopped working for HDMI. No screen is ever detected if I connect any USB-c to HDMI adapter, use any cable or any monitor in Windows or Linux. I tried several different monitors from Dell and Samsung, several USB-c to HDMI adapters including the one shipped with laptop, several HDMI cables. I also tried Windows 10 and Ubuntu 22.04. Everything works fine and screen is recognized and shows picture only if I use the one USB-c port on the right side of the laptop. Notice, that before the left two USB-c were working fine with all the USB-c adapters and monitors I tried.Other USB devices like wired network adapter or external USB drive work fine on those two left USB-cs. Uefi in my laptop is of the latest version 1.12.0.Could you please help me? Thank you!
