Extend/External the Desktop to a second display

I have two displays attached to my system.

The majority of the time, I just use one display, but several times a week, I require the second display.

Thus, I have created the following Aliases to easily expand/external the displays;
r:\>eset extend external
extend=displayswitch /extend
external=displayswitch /external

When I type extend at the TCC prompt, I have two active monitors.
When I type external at the TCC prompt, I just have my one primary monitor.

(Yes, my second screen is my main screen, not a normal setup.)

Typing DisplaySwitch.exe by itself will present you with the GUI method of projecting your monitors.
