I just bought myself a new 4K monitor and was very excited to watch some netflix in 4K. After trying some series, I noticed that it doesn't really seem to be 4K and when I click on a movie it just says HD and not UHD/4K. I've done some research on why it doesn't work and I should have everything needed for 4K netflix. List of specs below. I also have the UHD package for Netflix and internet speed of 100Mbps+. I've tried the Netflix app and Edge. In Nvidia Control panel, it says that my card and monitor are HDCP-Capable. I've also installed HEVC Video Extensions but that doesn't seem to work either. Really running out of options from my part.
