Abstract: Provided are a display system and a method for switching a display mode. Display modes according to kinds of programs are set up and stored. When detecting program activation by a user s request, an image of the program activated in the preset display mode is displayed after confirming a preset display mode in the program.

Abstract: An apparatus for adjusting a horizontal position of a video display appliance in which a display image is put in the center of a monitor screen. The apparatus includes a comparative circuit, a horizontal correction circuit and a deflection circuit. The comparative circuit detects an overlap signal representing that a horizontal flyback pulse and a video signal are overlapped. The horizontal correction circuit calculates a mean value of first and second horizontal values and transmits the mean value to the deflection circuit. The deflection circuit adjusts the horizontal position using the mean value as an adjustment value to put the display image in the middle of the monitor screen.
