I have a Problem with my GPD Win Max 2.
The USB4 port doesn't function as it should. It takes charge and some USB data (like drives), but no display out (any kind), and no PCIe tunneling eighter (eGPU).
I tried 5 USB-C dongles, no HDMI or DP video-out works.
I tried USB-C external display too, with no success. Every time I want to connect a display to USB4 the operating system freezes, sometimes an error notification comes up after I unplug the external display. Sometimes the built in display goes dark or the image corrupts, but it recovers every time when I unplug the cable.
I tried my Razer Core X eGPU too, it charges the laptop but no new device is shown in device manager. It behaves just like my AYA-NEO 2021 with USB 3.2.
The integrated HDMI port works just fine.
My AYA-NEO 2021 works with everything listed above but the eGPU, and naturally everything works with my OneXplayer Mini with USB4.
It seems like GPD had false advertising, or is my Win Max 2 defective?
Has anyone the same problems with a Win Max 2?
Edit: AMD version
