Optiplex 5820 with NVIDIA Quadro P400, 2GB, 3 mDP to DP adapter (5820T) and IIyama X2783HSU screen probleems
Hi,
i have an Optiplex 5820 with NVIDIA Quadro P400, 2GB, 3 mDP to DP adapter (5820T) atached to an IIyama X2783HSU. All worked fine untill I was so stupid to reinstall the PC because of some trouble.
With reinstalling and all the updates, Win11 was there......
Now I have major issue getting some view on the screen. It starts with the nice Dell Logo, then the screen says 'no signal detected' . After some time, and starting again, and again, I have my desktop.
Loging in, black, wait, wait, then (sometimes, with some luck) after 5 minutes or more, there is a desktop. And then I can only choose between 800x600 or 1024x768
I've checked everything, the monitor is good when atached to my laptop, changed the videocard with a diverend Nvidia one, changed kabels, updated all.
Restart in safe mode with default video, works fine but after reboot in normal mode it doasn't work anymore
somebody out there a clou??

looks like I have a hardware conflict: the Nvidia uses the same port as the Intel Xeon processor pci Express Root port A - 2030(???) How to fix that then??
