Abstract

The present invention provides a display device for displaying video frame signals transmitted from a computer. When the display device receives the video frame signals, it detects the number of horizontal scanning lines first, and then compares the number with a sampling reference table to obtain a target sampling number. If the number of pixel clocks generated by a phase locked loop does not match the target sampling number, the display device will adjust the frequency of the phase locked loop until the number of pixel clocks matches the target sampling number so that the display device can display video pictures correctly.
