In order to mitigate the problem of highlights appearing at the top of the picture, in addition to the beam being arranged to discharge overloads in the target area during line flyback, the beam is also arranged to operate in a highlight discharge mode for a predetermined number (for example one) of scanning lines after field flyback but before the end of field system blanking.
