- What is HDCP?
HDCP (High-bandwidth Digital Content Protection) is a technology used to prevent unauthorized copying of digital audio and video content as it travels across connections.
- HDCP 1.4 and 1080p:
HDCP 1.4 is designed for full HD (1080p) content and is sufficient for streaming or playing 1080p content from services like Netflix or Blu-ray discs.
- HDCP 2.2 and 4K:
To enjoy 4K content, all devices in your setup (source, cable, and display) must support HDCP 2.2. Without it, 4K content might not play or be downgraded to 1080p.
- Why is HDCP important for 4K?
HDCP 2.2 is crucial for protecting 4K content and ensuring it can be displayed at its intended resolution and quality.
- HDCP and streaming services:
Streaming services like Netflix and Amazon Prime often require HDCP 2.2 for 4K content delivery.
- HDCP and game consoles:
While game consoles are generally unaffected by HDCP for gameplay, entertainment apps on consoles may require HDCP 2.2 for 4K content.
- HDCP and cables:
Ensure your HDMI cables also support HDCP 2.2 for 4K content.
- HDCP 2.3:
The latest version, HDCP 2.3, supports resolutions up to 8K@60Hz.
(* DISCLAIMER - AMX products do not currently support HDCP 2.3 and 8K video *)
- HDCP and HDMI:
While HDMI is the most common connection type, it's important to remember that HDCP is a separate technology that works with HDMI to protect content.
