Streaming movies and TV shows in the correct aspect ratio is a major headache. If you download offline movies, the chances are high that you end up downloading the file in the wrong aspect ratio. It may happen in Chromecast too. But Chromecast automatically detects your TV and casts the content in that format. However, this works only for streaming apps. In offline casting, it is not possible. So, you need to change the Chromecast aspect ratio manually one way or another.
Built-in Cast apps like Netflix, YouTube, and other apps won’t have this issue. But many smartphones have come with a built-in Cast icon that allows you to cast your offline videos and images. While doing so, the aspect ratio in your smartphone and your TV may vary, resulting in the black screen below the content.
