An anonymous reader writes from a report via PCWorld: Microsoft made the bold claim on Wednesday that its Edge browser was the only browser of the big four browsers -- Chrome, Firefox, and Opera -- to play Netflix content at a 1080p resolution. PCWorld tested the four browsers and found this claim to be valid. The other three browsers capped out at a 720p resolution. Microsoft has been trying to boost Edge's reputation. Microsoft recently claimed that its Edge browser is more power-efficient than Chrome. (Opera later denied those claims.) This is the latest bold claim to come from Microsoft in regard to its Edge browser. Microsoft has even publicized a Netflix support document to show that Netflix streams at 1080p on Internet Explorer and Edge, and 720p on the other browsers. PCWorld used the "secret Netflix menus" that were first unearthed by Reddit users (Ctrl+Alt+Shift+D) to display the resolution and bitrate and confirm that Microsoft's claims are 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," reports PCWorld. "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."
