ShowCalibrator is a software utility that easily creates line-up slides for multiple display configurations. It compensates for any off-set (overlap or separation) between displays or projectors and can as such be used for projectors, LCD-displays and LED-walls.

The program even calculates the physical screen size based on the canvas used and provides position data for displays in animation programs like Watchout.

You can take a look at some test samples below. The green/red vertical lines are indicating positions of right and left edges of displays/projectors (green is right/starboard in marine terms etc.).
