Intel Q35 display driver (signed by MS) - does not reconnect signal after disconnection

    Question

  • Hi. I have been using the 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?

  • Hi,

     

    Please logon with Clean Boot,  update the Q35 driver, also update BIOS to the latest version for test.

     

    If the issue persists, I suggest to contact Inter Q35 Chipset support for further help:
