The Microsoft Edge browser returns a DRM error when you try to watch protected content and are using certain monitors or cables, such as VGA. This is because the media extension within Edge views the connection as unsafe, meaning protected content could be decrypted. There are a number of ways to continue watching content on All4 while using one of these connections:
- Change to another one of our supported HTML5 browsers (Chrome, Firefox, Safari)
- Switch to watching content in the Flash player
Or you can use a different connection, such as HDMI, to view content on another monitor.
