Question:  I am trying to use  “INOGENI 4K HDMI to USB 3.0 Converter” capture desktop image on MacOS, but every captured image has a Letter Box. It’s very ugly. So I want to know how to avoid the Letter Box.

Answer: First of all, make sure that the input format of your video source matches the one on the USB side, which is on the Mac. Second, make sure to disable the underscan/overscan setting on your graphic card, which is on the Windows side. This setting seems to be the cause of this letterbox.
