We have about 100 HP Elite 8300 SFF computers and we are having issues with dual monitors. We have them attached using a VGA cable and a Display Port cable.
They will work with no issues until the PC is rebooted. The monitor then will not detect. It will take 3 to 4 additional reboots before Windows will detect it again.
It happens on multiple makes of monitors. We have updated the video and monitor dirvers with no luck.
So far, the only thing that seems to help is to replace the DP cable with a DVI cable and a DVI to DP adapter.
This only happens on this model of PC. Other brands of PCs don't have this issue.
Any ideas would be greatly appreciated.
