2.4. Detecting Display Settings
Problem
You want to know the display settings for the device on which the movie is being played.
Solution

and
screenResolutionY
properties of the
System.capabilities
object.
Discussion

object to
determine the display settings of the device that is playing the
movie. The screenResolutionX
and
screenResolutionY
properties return the display
resolution

For example, the dimensions of a cell phone screen and a typical desktop computer display are different, so you should load different content based on the playback device:
resX = System.capabilities.screenResolutionX; resY = System.capabilities.screenResolutionY; // If the resolution is 240 × 320 or less, then load the PocketPC movie version. // Otherwise, assume the device is a desktop computer and load the regular content. if ( (resX <= 240) && (resY <= 320) ) { _root.loadMovie("main_pocketPC.swf"); } else { _root.loadMovie("main_desktop.swf"); }
You can also use the screen-resolution values to center a pop-up browser window:
resX = System.capabilities.screenResolutionX; resY = System.capabilities.screenResolutionY; // Set variables ...
