*Please note that due to the limit of USB 3.0 bandwidth, the frame rate of the captured video cannot reach 144 fps.

Solution 1:

Hardware requirement: The computer graphics card can simultaneously output at least two HDMI signals.

1. Physical connection:

Connect the capture device with the streaming/recording computer and make sure the device works. Connect the output of the graphics card to the capture device and monitor respectively.

2. Set the display:

Open the graphics card control panel and set the resolution at 2560×1440 and the refresh rate at 144 Hz.

 

The display mode of the two screens should be set to “duplicate”.

3. Configure the capture device:

If a capture card is used: Open the capture card control panel in streaming/recording software such as Amcap and Capture Express and then select “HDMI” tab. In the “EDID” part, click “Load” to load the EDID prepared by Magewell.

 

If a USB capture device is used: Run USB Capture Utility V3 and click “HDMI” tab. In the “EDID” part, untick “SmartEDID” to disable it.

Click “Import” to load the EDID file prepared by Magewell.

4. Now the device can capture properly.
