Screen Resolution Problem In WPF?

by

Keep in mind that all WPF locations and sizes are floating point with a unit of 1/96 inch. Not pixels. This makes your window designs resolution independent. Doing the math: height = 960 / 96 = 10 inches. With your video adapter set to 120 DPI (120/96 = 125%): 10 * 120 = 1200 pixels. Same for width: 1536 / 96 * 120 = 1920 pixels.

System.Windows.Forms works in units of pixels. You are getting less than 1050 for the height because it subtracts the height of the taskbar. But for WPF you always want to work with 1/96″, never pixels.
