My monitor wont display native res!

Basically we bought a HD TV the other day, and it has a VGA input on it so we connected it up, and the computer let me choose 1920x1080, and i looked fantastic.

I've now connected it back to my 19 inch widescreen moniter (1440X900 native resolution) and its all messed up

If i choose 1440x900 everything is squished together so there are black spaces on each side of the screen, and O's look oval. Its like the monitor doesnt know what native resolution its supposed to be. The monitor is also showing up as a Generic, non-PnP monitor.

Ive tried system restore, uninstalling video and monitor drivers, and finally tried a complete windows install, all to no avail, im currently running at 1280x720. The picture fits on the screen but it is still slightly squished, circles look like zeros.

Any ideas? Surely i couldnt of messed up my monitor like that?

Sorry guys panic over, it seems to have sorted itself out after a few restarts.
