Our USB device has done comprehensive tests before
shipment. Most of the incompatibilities we have
experienced are not from the USB capture device
itself, but from the sophisticated software and
hardware combination of PC or laptop. Please follow
the following suggestions to see any helps.
OBS is popular USB capture freeware and has
excellent compatibility. Please download it and
start with OBS if users are not familiar with USB
capture device.

The USB device supports HDCP mechanism to
protect legal content from pirates. If any HDMI input
with HDCP protection, OSD will display a message
to indicate HDCP existence. No capture will be
legally allowed if HDCP is detected. Please use
non-HDCP protected HDMI sources or disable
HDCP in order to get USB device work. Device like
PS4 supports such a feature to turn HDCP off.
Due to the complexities of OS and computer
hardware, different USB ports on PC or laptop may
have different performance or limitation. Please try
all USB ports to see if there are any differences.
Please must use the USB cable in box. We do not
guarantee the overall performance when the USB
capture box works with some other USB cables.
HDMI cable quality may also play an essential role
when capturing. Please be sure of that HDMI cable
can do 1080P@60 HDMI signal transmission or
better. Try different cables when the device is not
able to work as expected.
If audio has noise, please adjust sampling
frequency setting on PC or laptop. If the default
sampling rate is 48000 Hz, please select 44100 Hz
and vice versa. The path of setting sampling
frequency on windows 10 is:
