It would be good to see some logs after running these commands.

Here is the logs, so first command is VIC:0, the next is with 1080p

It would help to see full logs, but indeed, the Vero2 kernel doesn’t implement TMDS PHY toggling via sysfs. If I remember correctly, once an invalid VIC is selected, the kernel disables the HDMI PHY completely.

When this happens, does removing and plugging the cable back in help?
If so – we can probably fake an HPD event to simulate the same effect.

Yes, if I remove the cable and replug, it helps.
