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 1280*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 low-resolution mode, but I have the same problem: Vista boot-up and suddenly monitor stops working.
Update: I've tried to boot into safe mode but computer every time reboots spontaneously, so I can't do anything in safe mode.
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.
More info: I've tried the suggestion from How to change resolution on Vista when it keeps booting to an unsupported resolution? and set low resolution for boot via msconfig utility. What I see after reboot: PC starts with low resolution, I see desktop with all icons, then after 3-5 seconds computer spontaneously changes the resolution to the maximum (1280*1024 @ 17"). What does it can be? NVidia driver?
How can I disable this display resolution auto-changer in Vista? Or maybe there is another workaround?
