Determine the application screen resolution

Determining your overall screen resolution and knowing the exact size of your viewing area simplifies the process of creating an application for a multi-monitor environment.

Create a drawing that shows the overall monitor configuration. The drawing should show the resolution of each monitor and the combined resolution of all the monitors together. This drawing helps you visualize the horizontal and vertical pixel range for each monitor.

For example, if you have a composite screen composed of two horizontal monitors with a screen resolution of 800 x 600, then the top left pixel location of the second monitor would be at pixel 800 x 0. The screen pixel count goes from 0 to 799 for the first monitor and 800 to 1599 for the second. Using the drawing as a guide, you can determine the placement of application windows on the composite multi-monitor screen.
