The latest AMD Adrenaline drivers add support for PlayReady 3.0, which means specific AMD video cards now also support playback of Netflix Ultra HD content. With the addition of PlayReady 3.0 in the AMD drivers, all major GPU manufacturers now support playback of Netflix content in Ultra HD. Depending on the movie or series, also HDR is possible.
To playback Netflix Ultra HD content on AMD chip powered systems, there are some requirements. One of requirements is that the system needs to run Windows 10 with at least the Fall Creators Update. Obviously, it will also work with the yesterday released Windows 10 April 2018 Update. Ultra HD playback is also only possible with Microsoft's Edge browser, or Netflix's official app.
Both Netflix and Edge require HEVC which Windows 10 doesn't have onboard by default. This isn't really an issue, as the HEVC codec can be downloaded for free from the Microsoft Store where it's available under the name, “HEVC Video Extensions from Device Manufacturer.”
Another requirement is in the hardware, the GPU needs to support PlayReady 3.0. In case of AMD, this means at least a Polaris or Vega GPU, which means video cards like the Radeon RX400/RX500 and RX Vega support Netflix Ultra HD playback. Also APUs from the Raven Ridge line should be able to play Netflix content in Ultra HD.
The last requirement concerns the monitor, which means it needs to have support for HDCP 2.2.
The latest AMD Adrenaline drivers (18.4.1) can be downloaded from the AMD website.
