"No Signal" "Out of Range"

I have an Acer Aspire Notebook and a x241 monitor.  When I reboot Vista I often get "No Signal" or "Out of Range" messages.  The only way I can correct this by opening and re-closing the lid.

Check in bios see if there is an option to enable extend video (for external video). Also, check Acer website see if any update drivers for video?

no signal means it gets no signal
out of range means - there IS a signal, but the frequency settings do not correspond
so i assume you have a bad contoct somewhere : video output plug, cable, or monitor.
 the fastest check is with another monitor

Drop the refresh rate on the second screen to 60Hz and all will be well.

A driver update might correct it. I suspect that the driver is using a default refresh setting which is too high for the monitor. It might set up properly if the monitor is plugged in when the driver is installed. Try with the monitor plugged in, delete the video adapter in Device Manager and reboot. When it reinstalls automatically the settings should be usable.

When I have my external monitor connected to my notebook, I set the external monitor to 1900 X 1200.  This in turn changes the internal monitor to 800 X 600 which I cannot change.

In addition device manager lists  only the external monitor under Monitors.  Is this correct?

The issue is not resolution, but refresh rate, a different setting. Display Settings - Advanced - Monitor. Set it to 60 Hertz.

I have the Acer Aspire 9420 laptop and x241 Acer external monitor.  One has to opem the lid to restart Vista.  Otherwise it powers dowm. I have the correct setup for when the lid closed. Howver, I leave my lid open I do not have this problem.
