Using the HDMI Input on a Dell 7700 All in One

Explain the "thing" you are plugging into the hdmi port. It must have an HDMI output port. 

Ignore that, found the tiny second button... .However, does anyone have any suggestions on how you adjust the volume when using the monitor just as a 'tv' for the input?

So, what was your solution, Adam?  What is the "tiny second button" you speak of?

Much Thanks!  

Having exactly the same problem trying to connect an Xbox one. Any help gratefully appreciated!

I got the same problem just with xbox 360 xD

Right next to the power button at the bottom edge of the monitor, there is a small button called BIST (built-in self-test) When you press it may show video input select source on screen, which allows you to choose an external video. 

See: 

2. Display Built-in Self Test button/Input-source selection button 

Well, updated graphics card, bought new HDMI cable and still doesn't see the other monitor. It worked fine for a year now it doesn't see it? any suggestions?

@Janypat  Are you talking about an Inspiron 7700 AIO or some other PC model?

The graphics card in the Inspiron 7700 AIO can't be removed/replaced by the user.  So provide more details, including your exact PC model, version of Windows, and what graphics card you installed...

Ok so i really need help with changing the source on my dell 7700 there is a button next to the power button when i press it, it doesn't change the source so i do not know how to change it.

Did you end up figuring out controlling audio ?

I have connected firestick to it and both video and audio is working but only issue is that I am not able to control audio (volume up/down).

thanks in advance
