You can select the monitor buy Pressing Fn (function control key) and one of the Function key (F1 to F12) at the same time. Keys combination depends on the manufacturer. For Toshiba laptop it is Fn + F5. You can check the symbol on the function key or refer to a manual.



Please note that it will take few seconds before monitor selection is effective. Therefore, you should press the key combination, wait couple of seconds and press again if necessary. Monitor selection will toggle between built-in, external, built-in + eternal etc. in a sequence with graphic indication on the monitor. When you get the right monitor or monitors combination stop there. Then you may change the display properties.How do you configure your computer to use your T.V. as a monitor?
Check if your TV's specifications say if it has a VGA port or not. If it does look at the sidepanels of your laptop where you may find a VGA port too. Now you just need a VGA cable to connect between your laptop and TV/External Monitor.

Next you must go to Display properties and select the option of extended display.
