  • Apparatus for compensating for image rotation in a CRT display
    Patent number: 5021712
    Abstract: An image rotation compensation circuit for use with a CRT. The compensation circuit includes a winding which encircles the CRT and is oriented transverse to the path of the electron beam. A controller is connected to the winding and drives a current through the winding to create a magnetic field. The direction and magnitude of the current may be adjusted by the user to substantially cancel an external magnetic field and thus eliminate any image rotation caused thereby.
