I have an ASUS ROG PG279Q that worked with my official dock over HDMI up until yesterday when I updated to 3.5.5 and updated the Dock Official Firmware. The monitor is now no longer detected on the official dock no matter what I do. I have tested using different cables and a separate unofficial USB-C -> HDMI Portable Hub where the monitor is detected and working as expected.

Any ideas for troubleshooting the official dock? Is there a way to roll back the firmware update? Any guidance would be appreciated.

Thanks
