Primary Screen Resolution

[Vindicator209 1]

Well heres my situation, I have 3 screens, one of which is my primary screen, I wan to make a GUI that cover one screen only, but this has to work on other people's computers too, so I cant just do the division and math and junk, so is it possible to locate my primary screen or find the resolution of a primary screen?

Thanks

For the width of the desktop use: @DesktopWidth and for the height use @DesktopHeight for the gui settings.
