So I have received the ms2130 HDMI-USB3 capture card. <br>
The A/D AV converter & SV-HDMI/adapter is not received so far,
and I have not avialable my HDV camcorder (on service) to output
HDMI video stream with.<br>
<br>
Yet, I have initially run some verification tests on the ms2130
HDMI-USB3 UHD capture card alone, for what they are worth.<br>
<br>
As "UHD" (and/or USB3) is mostly generic used to identify this card
(while ms2130 almost not), the some output is piped and stripped
with grep "UHD".<br>

As the above doesn't list any 1920x1080 resolution, I wonder if it
list just format for the usb2 webcam and not for ms2130 capture
