- To enable split screen on Microsoft Edge, open “edge://flags/#edge-split-screen” on the browse, select “Enabled” for the “Microsoft Edge Split screen” option, and restart.
UPDATED 4/4/2023: On Microsoft Edge, you can now enable a preview of the “Split window” feature (via Reddit), and here are the steps to enable it in the stable version of the default browser for Windows 11.
Microsoft is building a new “Split window” feature on Edge, which, as the name implies, allows you to view two tabs in the same window to compare pages side-by-side. It’s similar to how the Snap Assist feature for Windows 11 works, but this feature makes it a little easier to split the screen to compare web pages.
Once you enable the feature, a new “Split window” button will appear next to the address bar. When you click the button, the page you are viewing will split, and then you will be able to select another to split the screen.
The feature also updates the tab visuals to let you know the page currently in focus. While in the split mode, you will have some additional controls a the top-right of the page, switch between linked and unlinked tabs, open the page in a new tab, or close the current page. Furthermore, you can resize the tabs by dragging the gripper in the middle left or right.
Enable split screen feature on Microsoft Edge
To enable split screen on Microsoft Edge, use these steps:
Open Microsoft Edge.
Type the following path in the address bar and press Enter:
Use the “Microsoft Edge Split screen” drop-down menu on the right and select the Enabled option.
Click the Restart button.
Once you complete the steps, click the “Split window” button and select the second web page to view side-by-side.
After enabling the experimental flag, you can enable or disable the feature from the edge://settings/appearance settings page under the “Select which buttons to show on the toolbar” section.
Update April 4, 2023: The feature was originally only available in the Beta, Dev, and Canary Channels, but now, the option to enable the feature is available in the stable channel (version 111).
