[SOLVED] setup with 3 screens, 1 of them is not turning on at loggin

Hello,

I have 3 screens on my computer.
It used to work without any issue.

After a disconnection of one of the screen, and a reboot, one of the 3  screen didn't come back.

At boot / reboot, I can see the bios and startup message, on logging interface  on the 3 screens, but as soon as KDE launch, I only have 2 screen.

if I go to "display configuration", only 2 screens are shown.

I don't know where to look to fix that...

Thank you for your help!
