I have new Acer Aspire Revo R3600 computer with Vista pre-installed. The computer has NVidia video adapter.

While connecting 17" LCD monitor (LG L1742S) via VGA cable it works fine, and I can change the resolution of the display from max 1920*1024 down to some other value, and after reboot the settings are restored correctly.

But when I'm connecting bigger full HD 1920*1080 display (LG E2250) via VGA cable then every boot I have the same problem:

  • I see boot progress window,
  • then I see MS logo,
  • then I see welcome screen
  • then I start to see desktop
  • and suddenly monitor switch off and show me the message about unsupported frequency of input signal

As I understand Vista tries to auto-change resolution and sets wrong parameters.

I've tried to boot into safe mode and into low-resolution mode, every time I have the same problem: Vista boot-up and suddenly monitor stops working.

I've tried to connect this monitor to notebook with Windows XP and has no problem to work with this display on its native resolution.

How can I disable this display resolution auto-changer in Vista? Or maybe there is another workaround?
