Nvidia GPU with 1440x900 monitor

[6_ERALDI]

Hello, I've recently bought a Nvidia Geforce GTX 560 Ti, and my monitor has a 1440x900 resolution.
First, this resolution isn't not available at Nvidia Control Panel.
Second, I've set a custom resolution, 1440x900, but it doesn't display properly. And I don't know what 'timing' to use. 'Automatic' doesn't display correctly.

So, what should I do to configure my GPU with the exact resolution of my monitor?

Why is it not available? It's a common res, it should be. Did you install the drivers?

Yes, I've installed drivers from nvidia.

How do you have it connected? Try setting the res in windows instead of the driver?

You shouldn't have to mess with custom res. If you've done everything right it should just show up and work. Maybe try removing drivers and install again? Get them Nvidia's website.

How do you have it connected?
