ok so you have a macbook pro with minidisplayport and you can see your desktop on your LG screen?
go to system preferences>displays>arrangement and turn off Mirroring (if it's on). This will give you two separate areas and look similar to this.
If you want quick access to this setting click the "show displays in meny bar"
a little pointer, you see on my setup that there is now one screen with no white bar at the top and one with. This marks where your main screen is (and where the menu bar and dock appear) you can click and drag this white bar to your new LG tv.
Most new tv's have a setting to fit the screen to the tv size. This is a setting that allows for edge to edge persision instead of overlapping which you'll see in older tvs. Take a look at your tv's manual for more about this sort of connection.
