This guide will go over how to capture audio and video from an Android device such as a Galaxy Tab S7 while maintaining a high refresh rate on the device's display and in games.
Capture device with custom EDID functionality
- Game Capture 4K60 Pro MK.2
- Game Capture Capture HD60 S+
Elgato 4K Capture Utility 1.7.5 or newer
- Download from http://www.elgato.com/download
Android device that can output video.
- Not all devices are able to.
Adapter to convert the port on the Android device to HDMI
- HDMI 2.0 adapter is required for 4K60 or 1080p120 signals
Hardware Setup Steps
1) Connect the HDMI adapter to your device.
2) Connect an HDMI cable to the HDMI input on your capture device.
3) To capture audio, ensure that your device's silence or mute switch is set to unmute. Using analog or Bluetooth headphones may also disable audio output over HDMI.
Advanced Setup Steps for high refresh-rate 120Hz devices
If you have an Android device with a high refresh-rate screen such as 90Hz or 120Hz, you may notice the screen and game are locked to 60fps, or in some cases 30fps.
The reason this change is required is that Android does not provide any controls for resolution or frame rate when connected to an HDMI display, or in this case HDMI capture device. It will always prefer resolution over frame rate and output the highest resolution, even if that means reducing the frame rate down to 30fps.
This EDID setting applies an EDID to the capture device which tells the Android device to limit the resolution to 1080p and output up at up to 120Hz instead.
1) Open the 4K Capture Utility software.
2) Open the settings and go to the device tab.
3) Click on the EDID Mode dropdown and select Internal.
4) Below that, from the EDID (Internal) dropdown select 1080p120 for mobile.
5) Now click on apply. The capture device may momentarily lose the Android device signal.
In some cases, disconnecting the HDMI cable or the adapter and reconnecting it may be required for the signal to correctly change to 120Hz.
5) Your device’s display and games will run at their maximum refresh rate, up to 120Hz.
