Video-related problems

No video input

The UVC-02 does not support copy-protected

video.

Might the video you’re inputting be in interlace

format, such as 1080i? (The UVC-02 does not

support interlace formats.)

Video input from a computer is

distorted.

If video is being input from a computer, the

image can sometimes be skewed, flickering, or

otherwise distorted.

This is a phenomenon called “tearing,” and is not a

malfunction.

Audio-related problems

No audio is output.
Audio volume is low.

Is the volume turned down on the UVC-02?
