5 FAQ
1. Q: I can’t hear any sound in the headphones when the HDMI Plus capture device
is connected to the computer and the headphones are plugged in the capture
device.

15 / 18
A: Enter the system sound playback device interface (Start Menu>>Control
Panel>>Hardware and Sound>>Sound>>Change system sounds>>Playback).
Check if the Headphones is ticked. If not, right click the device and select “Set
Default” and “Set as the default communication device”.
2. Q: How to use the computer speakers to play the captured sound after capture
device is connected?
A: Set the audio card as the default device in the "Playback device".
3. Q: How to solve the problem that the captured image is black when the video is
captured from PS4 and PS4 Pro?
A: Please disable the HDCP function of the game console, otherwise the capture
device cannot work.
4. Q: The screen shows “Unsupported signal” or flashes when I move or touch the
capture device.
A: Please use a new and high-quality HDMI cable, or the included cable of the TV
/ game console.
5. Q: When using a cable which is not the included Magewell USB 3.0 cable, signals
cannot be captured.
A: The USB 3.0 cable of USB Capture Plus is customized by Magewell, and cannot
be replaced with any other similar cables in the market. For purchase of extra
cables, please contact [e-mail].
6. Q: Will it affect the capture quality and the service life of the capture device if the
shell temperature is high when the device is working?
A: The capture device uses a metal case and a special heat dissipation design,
which can effectively dissipate the heat generated by the chip, so the housing
temperature may be high. As long as the user's operating environment
temperature is between 0 to 50 ℃, the capture quality and service life of the
device will not be affected regardless of the shell temperature.
7. Q: How to resolve the problem of dropping frames or the actual capturing frame
rate cannot reach the set format of 1080p60?
A: First, make sure that the capture device is connected to the USB 3.0 interface
on the computer. If it is connected to USB 2.0 interface, the USB bandwidth will
be insufficient, limiting the frame rate to be lower than 60 fps. Second, please try
to reduce the amount of USB devices simultaneously connected to the computer,
because other devices will share the bandwidth leaving insufficient bandwidth for
the capture device.
8. Q: I use USB Capture DVI Plus to capture the image and audio of my device via a
DVI data cable, but can only capture the video without audio.
A: DVI signal doesn’t have embedded audio. If you want to capture the video and
audio, you can convert the DVI signal to HDMI signal.
