Laptop External Monitor Resolution Problem

[1234543212345]

I have a acer 6930g laptop with nvidia 9600m gt graphics card, and a viewsonic va2213w monitor (22" and native res of 1920x1080 @60Hz).
When in windows i can't get the monitor to display at 1920x1080, it will display at 1680x1050@59Hz. However I can select the resolution in both windows setting and the nvidia control panel, but it just display 1400x1050 even though it says its displaying 1920x1080, i know this because the screen is all wierd and the monitor's osd says its actually at 1400x1050.
When running linux on the same laptop i have no problem display 1920x1080@60Hz.
I have tried older drivers, pstrip and a few other solutions all to no avail.

Any help folks?

Managed to fix this, in the driver release notes it says 1080p is not supported on the 9600m gt (dunno why). i tryed all the older drivers none fixed iths problem but i found this Forceware 185.85 - LaptopVideo2Go Forums that works perfectly so far.

I had the same problem with my laptop, I have the 9600M GT and cannot change the resolution higher than 1440x900 but according to nvidia its because I have the display cloned but my primary monitor runs at 1920x1200 so why doesn't the clone? I have the external monitor hooked up via the HDMI out so maybe the no support for 1080p is the issue.
