Redmond has been making all sorts of performance claims for Edge lately and it is safe to take most of them with a pinch of salt. But this latest one that you can only watch true 1080p content on Netflix over your PC, you need to use Microsoft’s Edge browser might actually be true.

A quick test of all four browsers by PCWorld proved this claim to be true showed that the other browsers were capped at 720p. Currently, Opera runs Netflix at a maximum resolution of 720p.

Microsoft has been doing its best to rehabilitate the Edge which, while better than Internet Exploder, lacked a lot of the functions which other browsers have offered for years. It seems that Redmond is trying to show us areas where Edge does better.

Microsoft slammed Google Chrome’s battery life, arguing that users on-the-go, and away from a power outlet, would be better served by Edge's superior power efficiency.

Now, Microsoft has publicized a Netflix support document, showing Netflix streams at 1080p on Internet Explorer and Edge, versus 720p on the other browsers. To do all this you have to use the “secret Netflix menus” unearthed by Reddit users (Ctrl+Alt+Shift+D) to display the resolution and bitrate. But Microsoft’s claim actually was true.

In a blog post, Microsoft claimed Microsoft Edge was built to take advantage of platform features in Windows 10, including the PlayReady Content Protection and the media engine’s Protected Media Path.

The company said it is working with the Open Media Alliance to develop next-generation media formats, codecs, and other technologies for UltraHD video, and with chipset companies to develop Enhanced Content Protection that moves the protected media path into peripheral hardware for an even higher level of security, and one that could be used to protect 4K media.
