Widescreen question

[PeteLucky7]

Ok, stupid noob question - if I get a widescreen tft (specifically looking at the cheapo HannsG 17" for about 90 quid) but my graphics card (256mb Connect3d x1800xt) doesn't have any widescreen resolutions supported according to the box, what's going to happen?

Cheers

Right, cheers. Another one, do most games support 1440x900 resolution, and if they don't will they just run in the middle of the screen with big black lines down the sides? If so, presumably they'll be limited to 1024x780 or something to fit vertically.. Am I right?
