Hello!
I have some random/consistent Problems with a Setup.
2 Nvidia PNY Quadro P400 in one PC with a Ubuntu & Ubuntu Server.
There are 5 Eizo S1934 plugged in and the latest Nvidia 550.120 driver is installed and the Firmware on the Nvidia Firmware.
The 5 Displays run sometimes and when you switch the Display to the correct sequenz something, the Displays is on but there is no video signal. Ubuntu see the EDID info and the systems said it’s on.
When you switch the sequenz it maybe shows again all 5 Displays a video.
Most of the time 2 of 5 don’t show a signal, sometimes one, sometimes artefacts shows one Display.
It’s completely random what’s next.
Also replugging the DP cable shows no effect.
I tested the same PC with Windows 10 & 11 and there is no Problem it’s always 5 of 5.
