Continuing with the installation, it is good to know that each screen you can assign a fund of screen different, just open the system preferences, and in desktop / screensaver you can select a custom image for each of the monitors.
Rejoice, because now you have a lot of space, the detail is in knowing how to organize it, the first step is to optimize it. When placing the portable next to the monitor, you will notice that it is "very low" and when working, the fact of having to look at such different levels is really uncomfortable, a suggestion would be to raise the portable about 10 centimeters will help you deal with both screens comfortably.
Logically, having the monitor connected you will use it as screen main and leaving the laptop screen as secondary, in these screens you can leave the palettes of the programs that fill space in the main monitor and that they do not allow us to see documents well (mainly the very large ones) and in the screen auxiliary you can put the controller iTunes, Mail, iChat, etc, a scale of programs that are not used daily, but if they are checked very often or as a second space for a utility with which you are working as support for the main application, you will save a lot of time by not having to eye or move windows to access them.
mouse locator is the solution if you frequently lose the pointer on the new screen, this application is pertinent to use to learn to control the position of the cursor, until you adapt to the large space you have now ... Very soon you will think about how you could work without two screensWell, now, the uncomfortable tasks of before will be the easiest.
