how do i get the width and height of the entire screen in XNA?
Adrian Grigore
This seems to be it (just googled for "xna screen width height" myself):
GraphicsAdapter.DefaultAdapter.CurrentDisplayMode.Height
GraphicsAdapter.DefaultAdapter.CurrentDisplayMode.Width
Eddie Parker
Empirically I've found that in XNA 4.0 I need to use
GraphicsDevice.Viewport.Width
GraphicsDevice.Viewport.Height
when running windowed mode, as I find
GraphicsDevice.DisplayMode.Width
GraphicsDevice.DisplayMode.Height
gives me the resolution of the entire screen.
Hopefully this helps someone else out.
GraphicsDevice.Viewport.Bounds - this returns Rectangle2D and it has parameters Width and Height.
