Grabber issue, Genki Shadowcast 2 Pro

Hey all,

Looking for some insight here. I recently picked up the Genki Shadowcast 2 Pro capture card due to its ability to capture hdr and vrr. When I have my laptop as the input my ambilights work absolutely fantastic, but when I switch over to my shield tv pro the lights do not do anything. When going into the web interface the live view shows a black screen. I’m trying to figure out why the input of my laptop would work fine but not my shield pro.

My setup goes like this, hdmi matrix with two outputs, one output directly to my tv and one output to my capture card, then capture card into a raspberry pi. All my devices go into the matrix; my shield pro, laptop, Nintendo switch etc.

I’m very lost have tried a bunch of different things;

With the Shadowcast 2 pro I tried

1: a cheap hdmi splitter that had no hdcp protocol in hopes it would allow a signal from the shield to the capture card

2: changing resolution on the shield

Then tried the elgato 4k x capture card and got the same results works beautiful using my laptop but then when switching to the shield it shows a “no signal” screen when viewed from the web interface.

Unless like you said it’s due to signals the grabber can not process.

So now I need to figure out how I could achieve what I have achieved with my laptop but also be able to have Hyperion work with my shield again too. Maybe a second grabber? I’m up for ideas.

Okay, I found a fix. On the nvidia shield tv in developer options you can change the hdcp option. This got the grabber to instantly work.
