In a method of processing an abnormal digital/analog convertor (DAC) of a video card, the video card comprising a first DAC and a second DAC, the video card connecting to an output interface. The method controls the video card to use the first DAC for converting data to the output interface through a first switch and at least one second switches in the video card. The method further detects whether the first DAC works normally. When the first DAC is determined to work abnormally, the method switches the first DAC to the second DAC for converting the data to the output interface through the first switch and the at least one second switches. |
