Macbook Pro 13 inch external display problem. Please Help!

Hi.
I have a 13 inch MBP running windows 7.
With the nvidia geforce 9400m
I'm trying to use a Samsung SyncMaster t220 with as an external display.
I'm using a mini display port to vga adapter.

So my problem is when I go to Nvidia control panel I only have the options to choose a resolution from 800x600 to 1280x800.
Am I missing something here? What am I doing wrong?

Please help I work mostly in Excel and the small res is killing me!

Zach

Thanks

Yep that was exactly the issue. I'm still getting used to this windows 7
I've got the Samsung to display at 1280x1024 but it still won't display at it's native 1680x1050.

I think it's an issue with the monitor. When I try to set it too anything higher then 1280x1024 the monitor just blinks analog digital like it's searching for a connection. Is it possible that the VGA only supports up to a certain amount and the rest and a dvi is needed for the full range?

Any thoughts on that?

Thanks
Zach

Display issue

I tried both 60 and 70 Hz. No luck with that.

Here are people who seem to be having a similar issue. Does that make any sense to you?

I'm running 32 bit windows 7

I tried it at 40Hz 1640x1050 and it blinked for a brief second with what appeared to be the right screen then went back. so I can see it but it just won't stick!

Windows does detect the monitor as a Samsung Syncmaster but I don't see a model number.

Sadly I don't have duel boot .. someone else set up the computer for me.
