HDCP

HDCP stands for High-bandwidth Digital Content Protection. It is a type of technology used to prevent unauthorized copying or sharing of digital content, like movies or TV shows, that is sent over HDMI or DisplayPort cables. Think of it like a special lock that only allows approved people (like your TV or DVD player) to see the content.

Imagine you have a special toy that you want to share with your friend, but you don't want them to take it to school and let everyone else play with it. You put a sticker on the toy that only you and your friend can match, so if anyone else tries to take it, they can't because they don't have the matching sticker. It's kind of like that with HDCP - the content is "stickered" so only approved devices can match it and view it safely.

If a device doesn't support HDCP, then it might not be able to display the content. Like the toy, if your friend didn't have the matching sticker, they wouldn't be able to play with the toy. Sometimes, compatible devices can cause issues with each other and the content won't display properly. This can be frustrating, but it's important to keep digital content safe and secure.
