Windows 7: Monitor out of range

I have been using Vista Home Premium 32 bit with a main monitor 32"TV and a secondary monitor - a 17" LCD PC monitor. Having transferred to Windows 7 on a new PC the secondary monitor now shows "out of range" on its screen. Can anyone tell me why this has happened. It is in the same place as previously used on Vista. Is it to do with 32 versus 64 bit or something I have overlookeAlec

Dennis welcome to the Seven Forums.

That error usually indicates that the resolution is set higher than the monitor can support. Assuming both are different resolutions make sure that the monitors are set to extended mode, and check that the resolution on the 17" is set correctly.

Yes, out of range is the monitor's way of saying it can't understand the resolution being broadcast to it. It can either be too high... to low, or even just a resolution in between that the monitor doesn't recognize.
You'll need to select it in displays and adjust the resolution.
I would make sure the refresh rate is set at 60hz as well. As this is the default refresh rate for most lcd monitors.
A 17 inch widescreen should have a native resolution of
1440x900
or 1280x1024 for a square or 4:3 display aspect.
