How do i get the drop down box for multiple display option to appear in the display setting?

I cannot get the drop down box for multiple dispaly to appear. I'm using a HDMI cable. I plugged it up to my TV and nothing happens. I did the steps to shut down my computer, then turn the tv on first, and then my computer, still nothing. I even pushed the button on the bottom left hand side of my computer, it goes black for a secong the says Game Mode No Video Signal. Even when i click on the detect button it says, Didn't detect another display. in the display example box it only shows one blue window with a 1 in it.

I tried following the guide, but the icon does not show up when i click on the volume controls. I tried connecting my laptop to the computer and I'm able to do dual screens through my laptop only.
