How to Cast YouTube from Your Phone to Your PC

Cast Youtube Pc From Android Ios Phone Hero

Casting YouTube videos or music from your iOS or Android phone should be seamless. If a TV, gaming console, Roku stick or other media streaming device is on the same Wi-Fi network as your phone, then you should get a little “Cast” icon on your phone’s YouTube app to stream straight to devices.

Theoretically, you should also be able to cast YouTube from your phone to Google Chrome on your PC. This feature used to work on PCs but was removed a couple years ago, leaving us happy casters at a loss. Luckily, with a few small tweaks, you can enable a special build of Chrome on your PC that will let you cast YouTube and other websites from your iOS or Android phone to your PC.

First, on Chrome on your PC you need to install the Chrome extension Custom UserAgent String. This will let you effectively change your PC’s Chrome version into one designed for smart TVs, streaming sticks, gaming consoles or other devices. You can set this to only apply for specific websites, so we’ll be applying it to the YouTube site designed for cast requests.

After you’ve filled both boxes, click the “+” icon to the right of them to confirm the custom useragent string.

Note: we found that the URL you enter into the “desired URL” box doesn’t always make the jump to the new “URL” box when you add it. If “” doesn’t appear in the URL box when you create it, just enter it into the URL box manually.
