Ever wondered what the google chromecast extension cable is for and how it can improve Chromecast video and audio quality? The Google Chromecast HDMI extension cable seems pointless because it’s so short, but actually it serves to improve video and audio quality.
How does the Chromecast extension cable do this? It moves the Chromecast device away from the other HDMI sockets in the TV, reducing power interference to the device. This means that the video and audio quality is better when it reaches your TV.
Simple, so now you know what the google chromecast extension cable for 🙂
