How to enable Chromecast support in Chromium Edge on Windows 10

The new Chromium Edge browser is based on Chromium and it would stand to reason that it has every feature that the Chrome browser has. That’s not entirely true. If you’re running the Chromium Edge beta, you should know that it can’t cast to Chromecast. The feature appears to be disabled but you can easily enable Chromecast support in Chromium Edge by changing two flags.

Set up Chromecast

Make sure you have your Chromecast set up. If you have an update pending, you need to install it first. Make sure that the Chromecast is connected to the same network that your Windows 10 PC is on.

Enable Chromecast support

Open Chromium Edge and type the following in the URL bar;


The page that opens is going to be very reminiscent of the flags page in Chrome because that’s what it essentially is. Use the search bar and look for the following flag;


Open the dropdown next to it, and select the Enabled option. Next, look for the following flag;


Open the dropdown next to it and select Disabled from the menu. After changing the value of both flags, relaunch Edge and you can start casting to the Chromecast.

Casting from Edge

In Edge, click the more options button at the top right and from the menu go to More tools>Cast to device. You will see the Chromecast icon appear next to the URL bar and a pop-up will open. Select your device from the pop-up and you will be able to cast the tab from it.

The Cast to device option is always going to be available in the menu but if you do not enable and disable the flags mentioned before, Edge won’t be able to find the device.

The older version of Edge was limited to what Windows 10 could do. Windows 10 has native Miracast support but it doesn’t support the Chromecast which is why Edge couldn’t cast to it. Chromium Edge no longer has that limitation so if you have the device lying around, you can use it with the beta version of Edge.

Changing the flags in Chromium Edge will give you more or less the same experience that you get when you cast from Chrome. You will be able to cast videos directly from YouTube, and you will be able to cast a tab from the context menu as well. As for the casting experience, it should be more or less the same as you get in Chrome.


  1. The latest Windows version of Chromium Edge ( Version 83.0.478.45 (Official build) (64-bit) does not have the #views-cast-dialog flag as Robert Novak stated. Enable the #media-router-cast-allow-all-ips flag as well as the #load-media-router-component-extension flag. I Click the Restart button in the window and cast away (a little Gilligan’s Island humor). I have a Ethernet attached Sony Bravia Smart TV that I use. I tested casting from my desktop PC using Ethernet and Wifi and both cast to the TV successfully.

  2. Thanks for sharing. I enabled the first flag (#load-media-router-component-extension). However, in my version of Edge (“84.0.516.0”) the flag #views-cast-dialog is not available. Any ideas on how to enable Chromecast?

    • Hi Robert. The second option was not available for me, but casting still works after just changing the first flag.

    • Yeah, I also had the same problem. In fact, when I click on the cast to a media device option, nothing happens.

    • I have the same problem….
      Can enable the first flag, but there is no second flag…
      Casting is not working “Device not found”

      It works perfectly on Chrome Canary!

    • In more recent versions of Edge you may not need to change the flag for #views-cast-dialog. The cast option appeared after step 1 of this guide. And casting is working even better than in Chrome for me.

  3. I have the latest Edge addition. When I follow the above instructions to enable casting to my chrome cast. when I enter the search for: #views-cast-dialog, edge gives me a message, no matching experiments. Now what?

    Thanks for any advise you can give me.
