I have DG43NB mobo, that have onboard X4500 graphics. Its supports 1900 x 1200 Resolution. But my LCD monitor is only capable of resolution 1024 x 768. I have to test some websites in resolution 1900 x 1200, how can i test?

Is there any concept of virtual desktop using which i can simulate resolution 1900 x 1200. I have windows xp installed.

How can I take browser screenshots at a higher resolution than my browser supports?

The answer, Courtsey of Snark:
You can do it with Firefox and 2 extensions: Web Developer and FireShot.

Once both extensions are installed, go to Tools - Web Developer - Resize - Edit Resize Dimensions... .

Add a new size, 4000 x 3000 (1900 x 1200 in your case). check "Resize the viewport" if you want only the page content to be 4000x3000 (1900 x 1200 in your case). If you don't check it, the complete window of Firefox (with toolbars, menu, ...) will be set to this dimension.

This 'viewport' concept is supported by some graphics cards.
Here is a ATI reference.
