Abstract (en)
[origin: WO0058938A1] The invention relates to a method and a device for monitoring the adjustment of the phase between the pixel phase of a graphics card and the scanning phase of a flat screen with an analogue interface in a computer system comprising a flat screen and a graphics card. A flag is placed after the phase of the flat screen has been adjusted on the user side. The flag is scanned when the flat screen is switched on or when the video mode on the computer is switched over and/or when the graphics card is exchanged and/or when the computer is interchanged. A display is indicated or adjustment of the phase starts when non-flagging is detected during scanning.
