This is info from three years ago.

"Playing protected content at 1080p or higher requires a protocol called HDCP 2.2.
Most monitors, laptops and tablets sold today are compatible with this standard and
should be able to stream without issues. 4K content, on the other hand, requires both
HDCP 2.2 and HEVC codec to work. The latter needs the user to buy a $0.99 extension
in the Microsoft Store.
HEVC is currently supported by only one Windows browser: Microsoft Edge.
While Apple TV+ works using Google Chrome and Mozilla Firefox, the resolution
and bitrate may not be the best.
"
It seems a kind of pessimistic proclamation. At a guess, at my house, I could
only meet this, by going out and buying a new 4K display device, and then it
would provide the display end. If I were to buy just an HD monitor (1920x1080),
the manufacturer might not feel the need to implement the latest standard.
But higher res monitors can be so whizzy, you need a new video card to
keep up with them.
While this sounds nasty, enough of your setup is working, it's likely as you surmise,
to be a video card to monitor issue of some sort. Not a whizzy enough standard being used.

You can see the hits just keep on coming here. Maybe 2.3 is secure ? Maybe ?
