For netflix to work on 4k you need hdcp 2.2

Piracy is one of the big problems in the world of multimedia content, to try to minimize it, security systems are used, which unfortunately often end up harming the righteous more than the sinners. We already told you that Netflix was going to be compatible with 4K multimedia content in Windows 10 but that it was going to be limited to Kaby Lake, now we know that it is due to the use of the HDCP 2.2 protocol.

Netflix limits 4K playback on Windows 10 to HDCP 2.2 protocol

In order to enjoy multimedia content at 4K using Netflix and Windows 10, you will need to use a processor that is compatible with HDCP 2.2 (broadband digital content protection). This technology offers the necessary bandwidth to be able to decode 4K content and that it is played smoothly, the bad thing is that the Intel Kaby Lake processors are the only ones that include it. Using HDCP 2.2 will make users with a processor other than a Kaby Lake unable to enjoy their 4K multimedia content on Netflix.

Fortunately, many multimedia centers and televisions are also compatible with HDCP 2.2, so the problem is reduced outside the PC. Another big problem facing PC is that browsers have been slow to agree on the proprietary content protection format to use, Microsoft Edge is the most advanced in this regard and already supports HDCP 2.2 so it is Able to stream 4K content on Netflix, but only with an Intel Kaby Lake processor.

Finally we point out that HDCP 2.2 is compatible with Polaris and Pascal but neither AMD nor Nvidia have ruled on whether their graphics cards serve to watch Netflix on Edge at 4K.
