Video Out not working

[BenniTec]

I have finally found time again.
I now have tested Arch Linux ARM and postmarketOS with the same error.
When connecting HDMI to the dock; dmesg says:

Code:

[  279.043860] sun8i-dw-hdmi 1ee0000.hdmi: EVENT=plugin
[  279.043921] sun8i-dw-hdmi 1ee0000.hdmi: EVENT=plugout
[  279.295984] anx7688 1-0028: DP state changed to 0x03

With postmarketOS v20.5 (kernel 5.10.4) and 15% battery it suddenly works now.

Full dmesg:
