Amazon Fire 4K

Amazon Fire TV (2nd Generation) supports video streaming in 4K Ultra HD for selected movies and TV shows.

4K Ultra High Definition (4K Ultra HD or UHD) offers enhanced picture resolution up to 2160p—which is four times greater than HD.

With Amazon Fire TV (2nd Generation), you can watch movies and TV shows offered in this format from Amazon Video and other streaming video services.

Tip: If your Fire TV is connected to a compatible Ultra HD TV, the Movies and TV sections on the main menu include “4K Ultra HD” categories, where you can find popular titles available to watch in UHD.
An “Ultra HD” indicator displays in your video playback controls whenever you’re streaming in 4K Ultra HD. Your screen also may flicker briefly or turn black while your TV display changes to UHD resolution.


System Requirements

To watch movies and TV shows in 4K Ultra HD on Amazon Fire TV (2nd Generation), you need a compatible Ultra HD TV with at least one HDMI input that supports HDCP 2.2 content protection standards.

HDCP is an access control technology required by most content providers to play back protected digital content. You can only watch movies and TV shows in 4K Ultra HD from Amazon Video and Netflix if your Fire TV is connected to an HDMI port that supports HDCP 2.2. Any other devices that are part of your home theatre setup (e.g. HDMI receivers, soundbars, etc.) need to support HDCP 2.2 as well. For more information, go to About Content Protection.

Fire TV devices automatically detect whether HDCP 2.2 requirements are met. You can also check to see whether your TV supports HDCP 2.2 from the Fire TV Display menu.

Go to Settings > Display & Sounds > Display and open the Video Resolution section. When video resolution is set to “Auto”, a notification displays in the right panel 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 labelled “Mobile High-Definition Link” (MHL), “HDCP 2.2”, “UHD” or “4K” typically support HDCP 2.2. Here also is general guidance on which ports support HDCP 2.2 for popular Ultra HD TV brands: • LG: Port 1 for most models
    Samsung: All ports or the MHL port.
  • Sony: Port 1 and Port 2 for most models
  • VIZIO: Port 1, Port 2 and Port 5 for most models

The user guide or product packaging for your TV may specify whether HDCP 2.2 is supported, as well. If you need more help, we recommend contacting the manufacturer directly. For contact information, go to Contacting Your TV Manufacturer.
Support for 4K Ultra HD video is not available for Amazon Fire TV (1st Generation) and Fire TV Stick.


Internet Speed

To stream in 4K Ultra HD, you need a high-speed internet connection of at least 15 Mbps. Some other video apps need even faster speeds to stream in 4K Ultra HD. For example, Netflix and YouTube recommend a connection of at least 20 Mbps.

Tip: Fire TV devices feature a network status tool you can use to check your Internet connection or diagnose connection problems.
