A: Windows 8 features a new Metro Start screen, which is a big change from Windows 7. To launch Metro-style applications, which are the new immersive-style applications, you need a resolution of 1024x768. This should be possible on most hardware platforms.

To use the Snap application capability, which allows two Metro applications to appear on the screen at the same time with one application using up most of the screen and the other giving a summary view, you need a resolution of 1366x768.

The same requirement exists for one Metro application and the desktop where your non-Metro applications run, for them to snap. The screen shot below shows an example of the Metro application Snap experience.
