Decklink Studio 2 HDMI INPUT

Hello, I am new to the forum however I have been using the above device for years.

I have a Decklink Studio 2 which is about 10 years old. Been working great but today I have been trying to INPUT via the HDMI. No matter what settings I use or change, I get no signal coming in from the HDMI. I have tried 2 different sources of HDMI and verified there is signal coming out, put when I plug it into the hdmi and set the desktop video app to hdmi I get nothing. Even when I load Resolve, it comes up with a message telling me there is no source?

I have tried everything I can think of for the past 3 hours and I cannot find any information or people having this issue?

Any idea what I might be doing wrong?

Thanks in advance.

What were the HDMI sources that you tried? They might be HDCP protected which wouldn't allow the Decklink to see them.

No one is just a camcorder, the other was a VHS deck going through a converter. But neither shows up?
