PC to HDTV (via HDMI) issues

This issue seems to be a bit too difficult to google for some reason but I feel like it's a simple fix...

I have an LG TV. Not sure if the model is important here.

The Comp is running windows 7 and has an hdmi port on it. Connecting it to the TV with the appropriate hdmi cable has no effect. The computer doesn't detect anything, the TV will act as though something is happening for a brief moment, then nothing.

The PC won't recognize it. I've clicked around the display settings, clicked "detect", looked around, nothing.

HALP!

How ya doing, buddy?

It's actually an Asus laptop. Not sure on the model number.

Also those suggestions didnt work

There's nowhere I can't reach.

wow, deni, that... actually worked.

I mean, it was strange. I was hitting the f keys and knew, yes, KNEW it wasn't going to work because I knew what each one did. Brightness, wlan on/off, keyboard lights bright/dim, then a key with a Zz on it. I hit it, knew it was going to go into standby, but when it came back the TV was suddenly connected.

AMAZING, PROBLEM SOLVED!

This thing is sticky, and I don't like it. I don't appreciate it.
