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.

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:
Start →Setting →System →Sound →Device
properties →Additional device properties →Advanced
