Abstract

An arrangement for maintaining even tube burn-in. The arrangement identifies active and inactive display regions on a display unit when video content is displayed on the display unit. When inactive display regions are identified the arrangement monitors the duration that the active display regions remain active. After the active display regions become inactive and a predetermined time period has passed the arrangement displays a corrective image on the identified inactive regions. The predetermined time period may be set by a user or based on the user's viewing habits.
