Asus G14 GA402XY 4090 - left USB-C Input doesn't Work with external monitor

Hello,

since several weeks the left USB-C (using the AMD iGPU) got defectice.

Hooking up my laptop to a LG TV via USB-C to HDMI Adapter and a HDMI cable to watch a movie, suddenly the picture got black and the laptop lost connection to the TV. Since then I couldn't get any picture signal to an external monitor or TV.

I tried Like 10 different HDMI to USB-C or DP to USB-C Adapters or cables and nothing worked ever again.

The HDMI Port ans right USB-C port running through the dgpu are totally fine.

Yes, I'm using the Laptop in Eco Mode. 😉

How can I fix this issue?

Is this Software- or Hardware-related?

 

Greetings
