Same issues, I have everything ok with edge://gpu except that it is showing up FALSE for HDCP2.2 support although NVIDIA control panel showing both graphics card and display being HDCP compliant
Sent a feedback via Microsoft Edge as well, running the following specs:
- GPU: NVIDIA RTX 3070 under Razer Blade 15" base (2021)
- Secondary GPU: Intel UHD Graphics
- External monitor (TV): Samsung Q80T 55"
- HDMI connections: HDMI certified 2.1 cable connected to both HDMI 2.1 port (Game mode and input signal plus enabled on Samsung)
- Current display settings (on TV): 120hz, 4k resolution, HDR enabled
- HEVC: bought and enabled
The only reason why I'm watching Netflix on edge is because it has 1.5x playback speed vs the Samsung TV app (which doesn't)
