Installed 14.04, new, and system will not discover my LG tv as second display using a hdmi connection. Can anyone help me to troubleshoot this problem? Also cannot get any sound out of system.

Switch everything off. Plug HDMI cable from computer to TV. Switch the TV on and set to the correct input (HDMI 1 or whatever). You should be getting 'No Signal' message on the TV. Switch computer on. Wait. Anything? The picture should come up on the TV or you should get a message once you are at the desktop on the computer that there is another monitor plugged in and do you want to use it (and how).

You may also want to try tweaking with arandr. It is in the repositories.
