thanks

Hello,

I am sorry for not answering to this bug report sooner; I cannot test
to reproduce what you say (I have only one MicroHDMI cable), and even
if I could, I really don't think I can do much to help. Your bug
report has a lot of interesting insight, but I will not say I am the
best equipped to make sense out of it.

The situation has evolved quite a bit since you filed the bug, and
having both newer firmware and kernel versions, I wouldn't be
surprised if this issue managed to fix itself. I understand (but don't
know for sure) advances have been made regarding vc4 support in
mainline Linux.

So, do you still have this behavior? Have you (or has anybody else)
been able to get dual-screen support on your RPi4? Or do you have any
promising pointers on this?

Thanks,
