PROBLEM TO BE SOLVED: To provide a method for measuring a full frame size from a display signal by a data enable signal and an apparatus therefore. SOLUTION: The apparatus includes a timing control device and a multiplexing device. The timing control device has multiple input terminals and a control signal output terminal. Each of the input terminals is capable of being coupled to a display bit of a primary color signal. The timing control device outputs a control signal through the control signal output terminal. When the timing control device is to perform display adjustment, the timing control device outputs the data enable signal to the multiplexing device and the multiplexing device applies the data enable signal to the timing control device. According to the data enable signal, the full frame size and position can be obtained. After the display adjustment, the timing control device changes the logic state of the data enable signal so that the timing control device can receive the primary color signal with its original display bit arrangement. Thus, the frames indicated by the display signal can be actually displayed according to the display adjustment.
