I have been using the CAC-1070 for years without issue. I recently installed the HEVC Extensions from the Microsoft Store so the Netflix app would support 4K playback. Now it shows the purple (HDCP unauthorised) screen when opening Netflix, and no amount of unplugging/plugging in the HDMI cable will reset it. As a workaround, I uninstalled HEVC Extensions and Netflix works only at max 1920×1080.
Would a firmware update resolve the issue, or would I need to buy one of the newer adapters to support the latest HDCP pass-through for Windows 10 apps? i.e. the CAC-2070? I don’t mind purchasing a newer adapter if need be.
tl;dr – I’m running my graphics settings at 3840×2160 @ 60Hz RGB 8-bit. I’m using Windows 10 Netflix app to watch content. It only runs at max 1920×1080 without HEVC Extensions installed. With HEVC Extensions installed, Netflix only shows purple screen of death. Uninstalling resolves it, but again only plays max res 1920×1080.
