ABSTRACT:
A display includes: a clock signal generator for generating a first sampling clock signal used for converting an analog video signal supplied from a host to a digital video signal; a tracking control circuit for generating tracking control data corresponding to a tracking adjustment key input; an A/D converter for converting the analog video signal to the digital video signal in synchronism with a second clock signal obtained by delaying the first sampling clock signal according to the tracking control data; a high frequency clock signal generator for generating a high frequency clock signal, and the tracking control circuit measuring the presently delayed time of the second sampling clock signal by means of the high frequency clock signal so as to adjust the delayed time according to the tracking control data.
