ABSTRACT:
The display apparatus includes circuitry for generating video signals for the display of still or motion pictures on a CRT or other display device. The apparatus further includes an arrangement for generating a test signal to display a test image to facilitate adjustment of the brightness (black level) setting of the CRT. The test image includes adjoining regions (100,102) of black and below-black levels, to forming a first image feature which is invisible at the correct brightness setting. If the brightness setting is too high, the first image feature is visible and forms a symbolic instruction indicating the necessary corrective adjustment. The test signal may be stored with picture information on a storage device.
