ABSTRACT:
The present invention relates to a display apparatus and a control method, which comprises a monitor displaying a picture by receiving a video signal according to a display data channel standard. The present invention is comprised of microcomputer including a voltage detector detecting a voltage level of said video signal, wherein the microcomputer determines whether or not the detected voltage level is beyond a predetermined allowable limit and controls the display apparatus to display an indication of an abnormality of the video signal if the detected voltage level is beyond the predetermined allowable limit. With this configuration, a display apparatus and a method for controlling the same, which can determine whether or not the voltage level input from a video card is abnormal, by detecting the voltage level of the video signal, and solve a unstable output generated from the video signal having the abnormal voltage level signal.
