========================
Detailed description：I have had my computer for almost 2 year. I have never had any issues with the docking station (USB C) were i have my external monitor and mouse and keypad connected. For two weeks ago the display stoped working. It lights up when i am connectint to the docking station but it gets no signal so after a couple of seconds it turns of.
I can also say that there is nothing wrong with cables or dock. The mouse, keypad and everything else works just fine...But not the display.
I have also tried to connect my other laptop (lenovo x250) and with that laptop everything including display works. So, there is nothing wrong with the equipment.

hello, i have the exact same problem. everything works via the Thunderbold connection except the monitor. I have a zenbook 13 with Windows 11.

The support advised me to reinstall the driver .. I should also start the system by pressing the start button. This also leads to the function. But only until a restart. Does anyone have a solution?

Hi there,
Can you specify the model name? do you have UX391FA as well?
And the issue happen after you upgrade to Win11? you did not experience it under Win10?
If so, can I have a screenshot of the update history?
Thank you so much.

Hi Charlie,
Can you reply the PM?
Both your SN and log are quite personal, so not that good to post it here public.
And you are able to share the log file or upload link to me in PM.
Thank you.
