HDMI转VGA和VGA转HDMI有什么区别？它们可以互换使用吗？

What is the difference between HDMI to VGA and VGA to HDMI? Can they be used interchangeably?
我们将进一步讨论HDMI和VGA之间的关系。当信号源连接到显示设备时，如果接口相同，可以直接购买电缆进行连接，但如果接口不同怎么办？例如，如果源是 HDMI 而显示器是 VGA 连接器怎么办？现在是使用转换器的时候了。

1、HDMI转VGA

HDMI转VGA线自带供电接口，相比转换器，转换线可以直接连接，无需额外转换，一根线轻松转换高清大屏，简单方便，适用于小米盒子、笔记本电脑、机顶盒、PS3等HDMI接口设备，连接电视机、显示器、投影仪等VGA接口设备，转换高清大屏画面。 Vention HDMI HDMI转VGA转换器是数字信号到模拟信号的转换，信号源是HDMI接口，显示设备是VGA接口，也就是说需要准备一条VGA线来连接。但由于VGA不支持音频传输，所以即使你有HDMI接口，你的终端设备也不会有任何声音。您需要连接其他音频设备或直接购买具有音视频同步转换功能的转换器。 Independent Audio Output 在分辨率方面，HDMI转VGA转换器支持1920*1080P分辨率和60Hz刷新率。 The Picture is Clearer

2、VGA转HDMI

VGA转HDMI是模拟信号到数字信号的转换，要求信号源具有VGA接口，即输入端是具有VGA接口的设备，显示设备具有HDMI接口，即输出侧。 Vention VGA转HDMI转换器，外壳采用铝合金，坚固耐磨，手感舒适细腻，最高支持1080P分辨率。需要配套HDMI线才能使用。 Aluminum Alloy Shell 因为它们的信号转换不同，HDMI转VGA是数字信号到模拟信号的转换，而另一个则相反，使用的处理芯片也不同，所以它们不能用于双向信号传输，而每种转换模式都需要相应的转换器。 Connection Diagram 还有一点要提的是，购买转换器最好是购买带有电源插座的设备，这样传输会更加稳定，不会因为供电不足而出现传输问题。 Audio & Power Supply
