    • 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.
    • 显示装置和控制方法技术领域本发明涉及一种显示装置和控制方法,其包括通过根据显示数据信道标准接收视频信号来显示图像的监视器。 本发明由微型计算机构成,该微型计算机包括检测所述视频信号的电压电平的电压检测器,其中,所述微型计算机确定所检测的电压电平是否超出预定的允许极限,并且控制所述显示装置显示异常的指示 视频信号,如果检测到的电压电平超出预定的允许极限。 利用这种配置,可以通过检测视频信号的电压电平,并且解决由视频信号产生的不稳定的输出,可以确定从视频卡输入的电压电平是否异常的显示装置及其控制方法 具有异常电压电平信号的视频信号。
