Hello everyone, Apologies if I'm writing in the wrong forum, this is my first time. I've just bought a LG 55ur80006lj 4K UHD Smart TV, I've got an Amazon Firestick 4K that I'm using with it, when I go to 4K content, sometimes it shows UHD at bottom or sometimes 1080p HDR on it, when I go to settings it mentions, for 4K I require a stable strong internet (which I have) and an HDMI port supporting HDCP 2.2 I wanted to know if the model I have, does it support HDCP 2.2 or not!! Thank you
