Watch Video in 4K Ultra HD on Your Fire TV

Compatible devices automatically detect whether requirements are met to stream videos in 4K Ultra HD.

Tip: If your Fire TV is connected to a compatible Ultra HD TV, the Movies and TV categories in the Fire TV menu typically include "4K Ultra HD" rows with popular titles.

Requirements

  • High-speed Internet connection of at least 15 Mbps. Some video apps (for example, Netflix) recommend at least 20 Mbps.
  • An Ultra HD TV with at least one HDMI input that supports HDCP 2.2 content protection standards
  • Other devices that are part of your home theater setup (such as HDMI receivers and sound bars) must also support HDCP 2.2.

To check if your TV supports HDCP 2.2 from the Fire TV menu:

  1. Go to Settings > Display & Sounds > Display.
  2. Open the Video Resolution section.
  3. Set your video resolution to Auto. A notification displays if HDCP 2.2 is not detected for your Fire TV's HDMI connection.

Tip: HDCP 2.2 may not be supported for all of the HDMI ports on your Ultra HD TV. Ports labeled "Mobile High-Definition Link" (MHL), "HDCP 2.2," "UHD," or "4K" typically support HDCP 2.2. The user guide or product packaging for your TV may have more information.
