HDCP 2.2
Amazon HDCP 2.2 on Fire TV: HDMI link does not support 4K content
Risk level
Low
Usually safe to check without specialist tools.
Urgency
Low
Quick answer
The HDCP 2.2 notification after setting resolution to Auto means the Fire TV HDMI connection lacks that protection, so 4K Ultra HD will not play. Use an HDMI port labelled HDCP 2.2, UHD or 4K and check any receiver or soundbar in between.
Safety first
Stop and check this first
- Never route the Fire TV through a splitter or adapter meant to remove HDCP: Amazon does not support that setup and protected content can stop playing. The right route is a compatible port and compatible equipment.
Safe checks you can perform
- Trigger the notice in Video Resolution
- Move to a 4K-ready HDMI port
- Run the Audio and Video Diagnostics tool
Leave these tasks to a qualified professional
- Do not attempt this professional task: Amazon support if a valid port still warns
- Do not attempt this professional task: Ask the TV or receiver manufacturer

Follow these steps
Note: Follow the documented order. An error code identifies the affected system, but it does not prove by itself which part has failed.
Trigger the notice in Video Resolution
- Who:
- you, from the Fire TV menu.
- How:
- go to Settings, Display & Sounds, Display, Video Resolution and choose Auto. Watch for the notification saying HDCP 2.2 is not detected on the current HDMI connection.
- Result that matters:
- confirming the notification belongs to the input you are using now.
- If the notification appears:
- switch the TV HDMI port as described in the next check.
- If it does not appear:
- the 4K issue comes from elsewhere, run the diagnostics tool.
- Evidence to keep:
- a photo of the notification and the HDMI input number in use.

Move to a 4K-ready HDMI port
- Who:
- you, with the TV manual or box at hand.
- How:
- find the TV port labelled HDCP 2.2, UHD, 4K or MHL and plug the Fire TV in there. If it goes through a receiver or soundbar, try it straight into the TV; set the TV resolution to 4K, HDR or FHD in its picture or input menu.
- Result that matters:
- no notification when you choose Auto in Video Resolution again.
- If it clears with the Fire TV direct to the TV:
- the unit in between lacks HDCP 2.2 or 4K pass-through on that port.
- If it shows on every port:
- check the TV manual to see whether any input supports HDCP 2.2.
- Evidence to keep:
- which port and which setup (direct or via receiver) clear the notification.

Run the Audio and Video Diagnostics tool
- Who:
- you, if your Fire TV includes it (not all models do).
- How:
- open Settings, Display & Sounds, Audio/Video Diagnostics. The tool checks the TV maximum resolution and refresh rate, HDR, Dolby Vision and surround support of the HDMI chain. Swap the cable for a high-speed HDMI cable as well.
- Result that matters:
- knowing the maximum resolution detected with your current setup.
- If it detects 4K but you see less:
- check your streaming plan includes 4K and your internet speed (Amazon asks for at least 15 Mbps).
- If it does not detect 4K:
- Amazon says it cannot play with that equipment; contact the TV or receiver maker.
- Evidence to keep:
- a screenshot of the maximum resolution detected and the cable used.

What it means
On Amazon's page about watching 4K Ultra HD on a Fire TV, the TV needs at least one HDMI input that supports HDCP 2.2, as does any AV receiver or soundbar in the chain. When you set Video Resolution to Auto, a notification appears if HDCP 2.2 is not detected on that connection. Fire TV models and TVs do not all behave the same, and the notification alone does not prove that the TV or the Fire TV is faulty.
