Create a full-screen image to adjust your monitor
Xtestpicture creates a full-screen picture that is intended to help you adjusting your monitor, resembling the usual TV test pictures.
The picture consists of some geometrical elements, like two crossing diagonals, a circle, a couple of recatangles. In the center, there’s a rectangle filled with vertical lines, to prove sharpness and video bandwidth, and a color area to adjust the color saturation and contrast.
That’s about all there is to be, doesn’t sound very impressive, right? Simply click a mouse button to get rid of it again.
