Hi, I have this grabber.

When I turn off the hdmi source, the capturer automatically enters some color bars or typical adjustment chart. This is possible to remove, I understand that it is not a matter of hyperion and if the capturer, since I have tried in vlc and when there is no hdmi signal, it puts the color bars and I would like a black one so that the lights go out.
Thank you
