AppleTV 4K Settings & EDID
Jan 07, 2025
Overview
The standard EDID on a 3G Just Add Power Transmitter does not currently display a 4K AppleTV at it's native resolution settings. To get an AppleTV to output 4K video, the default EDID must be modified.
Recommended Settings
- Video Resolution: 4K30 SDR
- Match Content:
- Match Dynamic Range: On
- Match Frame Rate: Off
- HDMI Output: RGB High
- Audio: Any
AppleTV Menu
- Download the latest update for the AppleTV
- Go to Settings > Audio and Video > Format
- Select 4K30 SDR
- Go to Settings > Audio and Video > Content Match
- Set Match Dynamic Range to On
- Set Match Frame Rate to Off
Set Transmitter EDID
- Log into the web interface of the Transmitter connected to the AppleTV.
- Note: If you cannot access the web interface, you can either Set a Static Route On the Router or Add a Static Route to Your Windows Computer to enable access to the Just Add Power devices.
- Go to the Video tab and to the section on EDID Settings.
- Set Startup EDID to Built In.
- Set Maximum Video Resolution to 4K30.
- Set Maximum Audio Format to the desired audio settings
- Click Apply.
- You will notice that the video drops out briefly as the new EDID is applied. You may need to power-cycle the AppleTV to force it to register the new EDID.
If these settings do not provide the desired result, please move on to the Set Custom EDID section.
