Hello,

The lightberry order has arrived, I bought the grabber recommended by the user @AmbiMod , but the result is exactly the same, I only have a black screenshot, and the LEDs do not respond to the signals sent by the hdmi ... what else can I do? Why does not it work for me?Do I have to configure some other parameter that I do not know?Do I need some different hardware? I am open to any idea.

Thank you very much.

Oks, I'll buy the Lightberry one, when I arrive I'll try it and I'll tell you if it works.
Thanks.

How can I know which is the HDMI2av chip?

This was the one that I bought.
