        In order to play a video file in the TV monitor, it can be played in the TV monitor only when<br>
        the information on the video file such as extension, codec, etc., matches.
    </p>    
<h2 class="tit">Causes and Symptoms</h2>
    
<ul class="cause-list">
        
<li>No sound is outputted when a video file is played on the TV monitor.</li>
        
<li>It occurs because the codec does not match when a video file is played.</li>
        
<li>
            If only a certain video file cannot be played, it’s because the codec information of that video file cannot be used in the TV,<br>
            and in such a case, it is not a product defect, but a symptom caused by incompatibility between the information in the file and the TV monitor.
        </li>
        
<li>To check the codec information on a video file, you can check the information on the video file through an encoding program after installing it on your PC.</li>

<span><strong>Encoding</strong></span><br>
            It is a process of compressing data to reduce the volume of original data when video, image or sound data are created using a computer.
        </div>
        
<div class="con-view">
            
<span><strong>Codec</strong></span><br>
            It is a compound word made by combining the initial letters of coder and decoder.<br>
            It is a method for storing and playing analog signals by converting them into digital signals, and there are several types such as MPEG series and WMV series.

    <p>If the video file information is different from the information specifications of video files that can be supported by the TV monitor, such video files cannot be played on the TV.</p>    <p>
        ※ If only pictures (jpg) and music (MP3) are displayed on the screen when a USB storage device is connected, the model does not support the video function.<br>

            For encoding, extensions and codecs desired by the user can be set.<br>
