Mobo: Biostar X370GT5-NF (hdmi 1.4)
CPU: Ryzen 3 2200g
OS: Win 10 pro
GPU driver: 19.2.3
Receiver: Denon S730H
Display: Optoma UHD300x (4k projector)
Would you please try the new drivers for Netflix 4k playback? I have a ryzen 3 2200g but my board doesn't have an hdmi 2.0 out, depending on your reply I might change the board with another HDMI 2.0 capable one.
While playing 4k content in Netflix if you press Ctrl + Shift + Alt + D you can see the resolution and color space.
In the worst case I will buy a gpu, which directly contradicts the use of 2200g as a htpc (shame)...
Note: I tried with mine but it displays 1920x1080 (hopefully due to my mobo). I have been waiting for the playready 3.0 support for Netflix (for ryzen APU) for months...
Appreciate for the help.
