Hi All,
We have just installed 200 + HP Elite Desk 800 G2 PC's into our environment. We have had constant issues with the display since install.
The monitors will go blank, with an error the display driver has encountered an error and has recovered, the screens blank for a few seconds then come back. This can occur multipe times per day, sometimes constantly. We have also experienced issues where the PC freezes, or keyboard and mouse are not recognised.
We have re-imgaed troubled PC's to no avail. We have updated graphics drivers, BIOS, chipset, still no solution at all.
Prior to this we had the G1 with no issues, we have confirmed it is not our image
Does anyone have any solutions or suggestions.
Thank you

Did you ever find a fix for this?
We also have likely a few hundred of these 800 g2 but in a large enviornment, so it is harder to track. The main complaints are coming from heavy excel users at this point.
I did a regedit from https://support.microsoft.com/en-us/kb/2665946
Creating Dword 32 named TdrDelay and setting the value to 8 at the location below.
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\GraphicsDrivers
I also disabled hardware acceleration in excel.

At this point its only been a few days of testing and results are varied. Some say improved, some are still having problems. Might try to disable lync's hardware acceleration as well, as I'm running out of options. Was hoping to find an HP service advisorty for this. Will likely be opening a case with HP as well. Still thinking this is a bad chipset or graphics driver from HP.

Thanks for your message.
No fix for this as yet.
We have tried the new Bios, Chipset and Video drivers etc, but these make no difference.
Have also tried that MS fix below still no luck, have also tried to disable the hardware acceleration in Excel, no change
Like you we have noticed heavy excel users have the issue, and most of the time this happens in Excel.
The only other thing we have tried and I have read works for some people is to use a VGA cable as opposed to the display port cables, that seems to work, but if its dual screens not as easy as it does not have a DVI port, so use the VGA port as opposed to the display ports
If you have any luck with any other fixes let me know, and I will do the same..
I think its a hardware issue, possibly a chipset or video driver issue from HP.

We are also having this issue with a new batch of HP EliteDesk with dual monitors. I had no issues with G1 and our screens are older Elite screens too. They are connected with VGA & Display Port to DVI adapters.

Hi There,
We have resolved this issue now. HP released a new video driver for this which resolves the issue. We have applied the new video driver and this has resolved the issue.
HP even advise this fixed the display driver adaptor error.
Good luck

Here it is
We installed that driver, no more driver failure errors.

I fixed this by working with HP and installing 4 drivers and updating the BIOS.
Drivers
sp72786 - Intel Chipset Supportsp
sp75384 - Intel Management Engine Driver
sp72807 - Intel USB 3.0 eXtensible Host Controller
sp76559 - Intel Windows x32 Graphics Driver
Bios
sp76626 - HP EliteDesk 800 G2 System BIOS (N01)
I suspect that only the Video and BIOS were needed.
