A display unit has an on-screen-display (OSD) control block for controlling display of OSD patterns on a screen together with a main image. The screen adjustment of the display unit is effected by a dedicated switch for effecting enlargement/reduction or movement of the effective screen area on the screen. The OSD control block enlarges/reduces or moves the OSD pattern by responding to the enlargement/reduction or movement of the effective screen area, thereby providing a visual scale for the enlargement etc. of the screen during the screen adjustment.
