the laptop's VGA output is controlled via the Fn key + one of the function keys (F1-F12) that has a monitor symbol on it.
hold down the Fn key and repeatedly depress that key until you get the proper kind of output you want, because there are multiple modes.
maybe what you want is 1+2. I don't know because I've not used 2 monitors before. I am only familiar with the keyboard switching.
you should make sure all your equipment (TV/monitor, laptop if that is what you are connecting) is on the same branch circuit of your house!!!
It can also cause ground loops which cause noise, etc.
wired ethernet cables I have used at home have not worked properly when I have plugged in my WiMAX modem on one side of the room and my router on the other side of the room with the rest of the equipment. I figure it was due to 60Hz hum or ground loops or some other electrical noise caused by being on a different branch circuit.
I was concerned for destruction of my equipment when it was acting up (at the request of technical support - I know you are supposed to play stupid!).
It would have been interesting to get out my DMM and actually measure what was going on across those wires.
Whatever it was, it was radical, and it went away when I put it all on the same wall.
one guy I know has a printer which went up in flames because he connected it across the room via cable (many years ago). could have been a house wiring issue, but I have had issues with networking across the room (noise). not a good idea.
