A quick solution is: access display settings, go to the nvidia tab in advanced properties (in my case the name of the gpu) -> screen resolution & refresh rates
There is a checkbox, unintuitively placed in the refresh rates box, uncheck "hide modes that this monitor cannot support. After this you will be able to move the resolution slider to your desired resolution.
I'm currently at my comp at work, with a quadro 4 card, so it may be different on your machine.
It looks like your machine screwed up the monitor's ini file, aka its driver. If you have a plug & play monitor, just try to remove your monitor cable while windows is running, it might be that Windows recognizes it correctly and thus overwrites the old file when you plug it in again.
Otherwise reinstall the driver for the monitor, you might want to use a software like 'Driver Cleaner' to erase the old driver before installing the new driver. If it doesn't work under your normal surrounding, you should do this in safe/repair mode - whatever your Windows version calls it.
