HDMI Input AND output on my computer.

Since I bought my computer a few months ago, I have always wondered how the HDMI Input on my computer would be useful. I'm of course using the HDMI output to connect it to my monitor, but an input?
Like, can I download some kind of software that would allow me to plug in my PS4 and capture some footage?

Yes you can.

Google up the Black Magic HDMI capture card to see what you are getting into.

No one I know uses that system due to the cost. Google "PS4 video capture" to see how folk do this.

External hardware is required?

Plugging in my PS4 directly to the HDMI port won't do the trick then?
If so, that's a bummer.

It might but

You didn't reveal what your PC is made out of. 99.9999999% of HDMI ports on PCs are output only. There were a few machines with HDMI inputs but that's rare.

In fact, it's never a good idea to plug an output to an output!

Output to Output? hell no!

You might have read my thread wrong, but I have an HDMI INPUT, not output...
I'm currently using my OUTPUT to display my computer on a monitor.

My computer is an i7 Alienware Steam Machine, with x1 HDMI output and x1 HDMI input.

Until this post I didn't know it was such a model.

If the input is failing you have a warranty and support issue.

Well you have to have a PC that has HDMI in and out.

My Alienware 18 has HDMI in and out but I've never used the HDMI in. On the Alienware there is a function key that's controls whether it's in or out. The 18 was discontinued by AW and I believe the 17, 15 and 13 I don't come with HDMI in ports.

Re: HDMI in

So I assume the documentation or FAQ for this model from Dell will tell how to use it. If not, Dell Customer Service might know.

How vague can Dell chat representatives be?

Logs of my chat with a Dell guy:

Them: HDMI output is used to connect to an external monitor

Me: I know that. Not sure about the input, though.

Them: the HDMI in is used to connect a console to a different device say like a computer to run games on it

Them: also the HDMI in is mandatory on all the consoles as they need to run the games with full HD resolution

Me: So I would connect my Alienware to another computer?

Me: Or would I connect my Alienware to, let's say, a Playstation 4 console?

Them: yes you can do that

Them: yes any computer that comes with an HDMI in you can connect it to that.
the play station as well

Me: So.... What is the usefulness to connecting a PS4 to my computer?

Them: well JF there are certain games that can be stored on a Microsoft console but not on the Alien ware and there are some games that can be stored on play station but not on the there are certain games that are especially designed for PS4 and if you wish to play those games you can connect it to this.

Me: So..... I can connect my PS4 to my Alienware to play PS4 games on it?

Them: yes

Chat ended.

Remember you didn't lead with your Dell specs.

So I didn't go and research what this Dell can do.

It appears it's not going to record HDMI since HDMI is protected content and I will upset some that want to repeat/rehash all that.

If you want to record PS4 play, you should research how folk do that. Then copy what they found to work.

Specs don't mean you can record.

HDMI is that way and upsetting to those that want to record.

There is no way Dell can put out a HDMI recorder without breaking rules or laws.

At best it should allow input to show on the display. Not record.

So obviously at this point in time...

YOU have no uses for the hdmi input but that doesn't mean in the future it may not come in handy. You will know, when you need it. Have fun.
