ABSTRACT:
In a liquid crystal display apparatus connected to a computer, a screen size detecting section detects screen size data indicating a size for one screen from a horizontal sync signal, a vertical sync signal, an image data signal and a dot clock signal. The horizontal sync signal, the vertical sync signal and the image data signal are supplied from a computer. A dot clock signal generating circuit generates the dot clock signal from the horizontal sync signal. A control section controls the dot clock signal generating circuit to generate the dot clock signal having a target frequency based on the detected screen size data, the horizontal sync signal and the vertical sync signal, such that the dot clock is adaptive for the computer. A display section including a liquid crystal display unit, displays the image data signal on the liquid crystal display unit in response to the dot clock signal having the target frequency.
