Which browsers allow you to stream Netflix content in the highest quality possible? For Windows users, you’ll need to use Microsoft Edge, while Mac users must stream with Safari, according to the Netflix Help Center. Unlike Chrome and Firefox, these two browsers support hardware-based DRM systems, with Edge using PlayReady and Safari using FairPlay. Because hardware-based DRM provides greater protection against recording, Netflix allows its subscribers to stream content in 4K resolution using these two browsers.
If you’re paying for the Premium plan and want to get your money’s worth, you should switch to Edge or Safari, both of which are available by default on PCs and Macs. There is one partial exception to all of this, which is that Netflix allows Chromebook users to stream content in the Chrome browser at up to 1080p rather than 720p. If you’re on Windows, you can alternatively use the Netflix app rather than a browser, which automatically allows you to stream in Ultra HD, according to the company.
