AnandTech received word that Netflix 4K support for discrete Vega video cards and Raven Bridge-based APUs will follow at a later point:
Taking a step back, 18.4.1’s beta PlayReady 3.0 support for Polaris is in line with AMD’s previous guidance on the matter, where PlayReady 3.0 support was to come with driver updates this year. That being said, production-ready PlayReady 3-capable graphics drivers for Ryzen desktop APUs were originally intended in early Q2, an announcement quietly made alongside the launch of AMD's Ryzen 5 2400G and Ryzen 3 220G. In any case, AMD gave a general update simply stating that PlayReady 3.0 support for discrete Vega graphics and Raven Ridge-based APUs remains under development and is planned for future driver releases.As a reminder, to enable 4K Netflix streaming on a PC, you need an awful lot of items. Here's a quick recap of the basics:
