Switch Recording from TV

Hi, I'm new to using OBS and Video Capture. I'm trying to record my Switch off of my TV to my MacBook Pro. I have an HDMI connection from the Switch to the TV. I have an HDMI connection from the TV to the Video Capture Card (input). I have a USB 3.0 connection from the Video Capture Card to my MacBook Pro. I've downloaded the OBS software, but when I try to create a video, the screen shows up as black. The USB 3.0 connection is selected within the Video Capture Device in the OSB software. I am running MacOS 12.7. Can anyone share how to get the input to recognize in the software so I can record what is on my TV screen?

Your wiring order is wrong.
HDMI ports on your tv are one-way, and will not send video to your capture device.

You need to connect your switch to the HDMI IN on the capture device, then the HDMI out from the capture device connects to your TV.

HDMI ports on your tv are one-way
HDMI ports on *everything* are one-way.

The Audio Return Channel (ARC) might cause some confusion here. It's audio only, as a special add-on to allow a home theater system to play content from the TV's internal tuner, or to feed the TV from a Blu-Ray player, both using the same cord. But it's only the sound that comes back the other way, not the picture.

To really understand this stuff, you really need to keep the picture and sound separate, and handle them separately. Sometimes they run together on the same cord, sometimes they don't, and they may even run different directions on the same cord, but they're always completely separate concepts:
- Blind sound
- Silent picture

A wire itself, or a passive cable, is bidirectional (and analog, even if it carries digital signals that are corrected as such at the receiving end), but the things it plugs into are not. An active cable becomes uni-directional because of the *electronics* in the cable, not because of the wires.
