Hardware Is it possible to output docked mode video through a laptop?

[AkiraKurusu]

I want to be able to run my launch-model Switch's video output (docked, through HDMI) through my Macbook Pro, since I don't have a TV or monitor handy at times - and I cannot stand the reduced resolution and sound quality of handheld mode, ugh, or the bloody JoyCons.

It is possible to do such, and if so, how? I've got a HDMI-to-USB-C adapter, and plugged it into my Macbook Pro, but...nothing. Do I need to fiddle with display settings or something?

If a device doesn't have a display input port, it's not going to display it.

Wrong

streaming it to the computer isn't entirely the same as just wiring it up to a screen, but sure, it works

3 main options if the laptop does not have a video in option (which are super rare, and I don't think I have ever seen on a mac)

1) You hack the Switch and do the network video thing. Not ideal really.

2) You get some kind of video capture device for the laptop. Could be a bit pricey for one that operates at a suitable resolution and latency but people have done this before you.

3) Internally most screens are going to be probably embedded displayport in their protocol, though you will have to check. The same things people do to wire up otherwise nice working screens of dead laptops also work to create a video pass through if you get really crazy. This is quite the engineering feat on a normal laptop, for something as anti user serviceable as the average piece of apple nastiness then if you are asking this question you are probably nowhere close. The screen will only display what is coming in via the cable (I guess you could buy further devices to blend in footage/do picture in picture and you are also back to network or buying capture devices if you wanted to do that.

That Genki one looks a whole lot faster then my cheap usb capture thingy (bought for like $15).
And by the way: Can you post a pic of your "HDMI-to-USB-C adapter"?
