Dear Maintainer,

*** Reporter, please consider answering these questions, where appropriate ***

   * What led up to the situation?
On my raspberry pi 4, with an image from raspi.debian.net both monitors worked, then I upgraded to Sid which upgraded raspi-firmware package and after rebooting, only one monitor worked.

   * What exactly did you do (or not do) that was effective (or
     ineffective)?
I downgraded to Bullseye raspi-firmware version, rebooted, and both monitors worked.
I then downgraded to Bookworm raspi-firmware version, rebooted, and both monitors worked.

   * What was the outcome of this action?
after rebooting with either Bullseye or Bookworm raspi-firmware verison, both monitors worked, but with the Sid raspi-firmware version, only one monitor worked.

   * What outcome did you expect instead?
I expected both monitors to work.
