Odd Graphics Issue

[talksr]

Has anyone else had this issue? I have been unable to get to the bottom of this.

 

HP system with a Nvidia Quadro P2200 GPU connected to 2 x DELL UltraShartp UP2716D monitors. The GPU has a 3m DisplayPort 1.4 cable going into monitor 1 on DP in port. From here, it goes to monitor two via DP Out port to miniDP In in on the second monitor.

 

It all works with no issues at all, unless.....

 

1. You boot the system with both monitors turned off. When you then turn them on, the system (which seems to be in a booted state but unresponsive to caps lock/num lock) will switch off, turn back on, try to boot and then switch straight off again. You can see the HP boot screen so graphics are working, eventually, it will go to Automatic Repair. It states Windows couldn't load correctly. If you try and restore, it will fail.

 

 

2. You boot the system with monitor 1 on only and monitor 2 turned off or set to HDMI rather than MDP. The system would do the same as point 1 and go to Windows couldn't load correctly.

 

 

The only way I have been able to salvage the system is by opening advanced restore options, going to CMD running the command: 'dism /image:f:\ /get-drivers |more' and looking for any drivers listed with Nvidia in the name. I would then run a command for each Nvidia driver like this: 'dism /image:f:\ /remove-driver /driver:oem39.inf'/ If I then rebooted, the system would come straight back on with no issues.

This is a time consuming job not helped by the fact the SSD is encrypted so each time, I need to find and type in the encryption key just to get the CMD prompt up/

 

 

The workaround was, just make sure the monitors are both on and set to the correct inputs on the monitors, and it has worked nicely. We also tried switching the monitors around, so one became 2 and 2 became 1, but it made no difference. We have tried five different display port cables of varying length, quality and makes - that also didn't help.

 

The PC has now been changed to a DELL Precision 3630 with an Nvidia Quadro P620 so not as fancy as the last one. Guess what, exact same issue.

 

I can't understand, is this an Nvidia specific issue whereby Nvidia GPUs are not liking these two monitors, or is there something wrong with these monitors? If I put the system on two HP monitors, no isuses at all. I am sure I also tried two DP cables, one to each monitor and still had the same issue.

 

I have not had this issue with any other of our other systems, and this is the only desk we have with those two Dell monitors. I understand the monitors were quite expensive, so they really do need to be utilised.

 

Has anyone else had an issue like this? All devices in Dev Man are fine, no errors.

 

Here is an example from the event log. This is where the system is booted with monitors off. When monitors are turned on, this is what happens:

I forgot to mention, I have also spoken to NVidia and tried deleting and reinstalling updated GPU drivers, that also did not help and sometimes, the system immediately rebooted whilst installing the graphics driver only to fail to boot again which would suggest a GPU fault, however we are getting the same on a totally different computer and we don't get this when using other monitors.

It's an irritating workaround, but my experience with DP has been really variable. I have a couple of suites of new PCs where I had to use a few HDMI instead and DP would not work at all. Random.

 

Have you tried using HDMI? May need converters from the GPU.

Not had this, so clutching at straws, but...

 

Similar problem, but with USB devices here: https://www.tenforums.com/drivers-hardware/73790-driver-driver-wudfrd-failed-load-device-root-wpd-0000-a.html#post2571286 may be worth trying that fix.

 

The "windowshellofacesoftwaredriver" suggests something to do with the Hello face unlock capability. Do you use it? If not, can it be disabled?

 

Re drivers, have you tried DDU to root out all traces of old GFX drivers? https://www.guru3d.com/download/display-driver-uninstaller-download/ Have you allowed the monitor drivers to install (if they have such a thing)? May be worth installing them if not, or seeing what uninstalling or disabling them does if installed.
