This is a follow-up to a thread created on
Microsoft Technet where Microsoft said I should try ask Intel for help:
Intel Q35 internal display chip on my Dell PC a long time. I found
that if I removed the igfxpers.exe which seem to do automatic-checking
for new displays that are connected.
When igfxpers.exe was running on Vista, I could disconnect a monitor
and then reconnect it and it did not find the signal. But if
igfxpers.exe was not running, I could remove a monitor and then
reconnect it and it worked fine.
However, in Windows 7, this behavior is not the same. Whatever I do, I
cannot reconnect a monitor. I always have to reboot the computer to
make it detect the signal.
Do anybody have any clue for fixing this? Or do I have to reinstall Vista?
