I’m trying to calibrate the Cintiq 13HD touch and the pen calibration targets don’t appear on the screen. How do I calibrate it?

If Windows 7 is set to the larger fonts (150%) then the pen calibration targets don’t appear on the screen. To change this, go to the Control Panel on your PC and select Display. Change the font size to Medium – 125% or Small – 100%. Selecting larger fonts changes the size of every item on the display, not only text.
