Resolution and scaling on Windows Phone

Originally posted to Shawn Hargreaves Blog on MSDN, Monday, July 12, 2010

Windows Phone includes a hardware image scaler. This allows XNA games to choose what backbuffer resolution they want to draw to, regardless of the physical screen size. You draw at whatever size you like, then the scaler adjusts the resulting image to fit the screen. This is similar to how the video output works on Xbox 360.

Note: scaling was not implemented in the CTP release of the Windows Phone Emulator, but is fully supported in our recent beta version.
