I review the AV Access HDMI 2.0 Splitter and use it to stream HDCP 2.2 copy protected video content from my Samsung Galaxy s21 Ultra android smart phone to a 4k external monitor using an usb-c to HDMI cable. Worked pretty good but was only able to stream 1080p from Amazon Prime because 4k videos caused my phone to shut down and crash, because I'm still using an older HDMI cable.
