An arrangement for compensating against the magnetic field of the earth in a picture tube in remote-controlled video-display equipment, in which a compensating voltage is generated by a remote-control channel in the video-display equipment. This voltage is applied to a compensation coil in the picture tube. Current through the coil is adjusted in finely-divided incremental steps, and the current is continuously adjustable. The compensation voltage is applied to one end of the compensation coil, whereas the other end of the coil is supplied with substantially half of the operating voltage of the display equipment.
