LED显示屏到底要不要配视频处理器？

来源：部分创锐特，部分慧聪日期：2020-07-01

<p>从行业发展而言，现在比发送卡+视频处理器更流行的，当然是二合一，例如卡莱特的X系列。性价比更高，使用更方便。</p><p>而LED视频处理器对于创锐特LED显示屏的作用，可以归纳为视频处理（尤其是点对点功能非常常用），多画面处理（例如画中画、三分屏、多分屏），多种类视频输入信号处理和转换（例如HDMI\DVI\VGA等)，等等。</p><p><br/></p><p>以下转自慧聪</p><h2 class="rich_media_title" id="activity-name" style="margin: 0px 0px 14px;
