Why can’t I rotate the display with ChangeDisplaySettingsEx?
If you have one of those cool swively LCD displays (or if you decided to build your own ), you naturally want to tell your video card to display rotated output, so you can take advantage of the portrait orientation. And naturally you would think that calling the ChangeDisplaySettingsEx and using the dmDisplayOrientation field of the DEVMODE structure would do the trick
