Abstract

Die Erfindung betrifft ein Verfahren und eine Einrichtung zur Überwachung der Einstellung der Phase zwischen dem Pixeltakt einer Grafikkarte und dem Abtasttakt eines Flachbildschirmes mit einer analogen Schnittstelle in einem Flachbildschirm-Grafikkarte-Rechner-System. The invention relates to a method and a device for monitoring the adjustment of the phase between the pixel clock and the sampling clock of a graphics card of a flat screen with an analog interface in a flat panel graphics card computer system. Dabei wird ein Merker gesetzt, wenn die Phase des Flachbildschirmes benutzerseitig eingestellt wurde. In this case, a flag is set when the phase of the flat screen was set user side. Der Merker wird beim Einschalten des Flachbildschirmes oder beim Umschalten des Videomodus am Rechner und/oder dem Austausch der Grafikkarte und/oder beim Austausch des Rechners abgefragt und es wird eine Anzeige gegeben oder eine Einstellung der Phase eingeleitet, wenn bei der Abfrage festgestellt wird, daß der Merker nicht gesetzt ist. The flag is interrogated in turn on the flat panel display, or when switching the video mode of the computer and / or replacement of the video adapter and / or the exchange of the computer and it is given a display or initiated an adjustment of the phase, if it is determined at the query that the flag is not set.
