a video data supplying unit to output the video data;
a synchronizing signal generating unit to output the plurality of synchronizing signals, and convert the frequency of the synchronizing signals in response to the frequency-conversion signal; and
a frequency-conversion determining unit to generate and output the first selection signal relating the frequency-conversion prediction information in response to the frequency-conversion signal.
3. The apparatus of claim 1, wherein the synchronizing signal detecting unit detects an unstable period of at least one synchronizing signal and enables the second selection signal.
4. The apparatus of claim 3, wherein the synchronizing signal detecting unit counts data enable signals from the synchronizing signals in accordance with a dot clock to detect an unstable period of the data enable signals.
5. The apparatus of claim 1, wherein the liquid crystal display part maintains and displays the image of previous frame on converting the frequency.
