What happens if you tell direct x to run a window in an unsupported mode in full-screen on a laptop? Like.. suppose you have a game that runs fullscreen at 1920x1080 and doesn't automatically scale down or list adapter modes etc... And you just make that window and tell direct x to full screen it on a laptop that supports a maximum resolution less than that. What's the result? I ran a 16x9 app that was too large on a macbook and it seemed to handle it gracefully and just scale everything down. What magic is this? Where is it happening? Vid card driver? a feature of dx? the os? What SHOULD I be doing if anything if my res is larger or unsupported?
