In the app store, a few bunch of paid apps turn free for a day or two.
Today we take a look at one such app. This one's special! Especially because of the purpose it serves! The app we're gonna tell you about is Splashtop Wired XDisplay.
It basically Turns your iDevice into a secondary monitor. It is ideal for those who need more screen real estate in a pinch.

Using the iPad as a screen extender can serve several purposes.  For instance:
  • Fill your iPad screen with widgets, folder shortcuts, an IM buddy list, Skype, Twitter, Photoshop palettes, and other utility apps.
  • Display one screen to the audience while reading notes from the hidden iPad screen.
  • View spreadsheets across monitors so that all columns can be seen without scrolling.
  • Park background entertainment windows such as Netflix, Hulu, or social games (FarmVille) on the iPad while working.
  • Edit an HTML page on one monitor while viewing the rendered web page on the iPad.
  • Play Flash movies and videos on your iPad in bed or on the couch and avoid the hassle of transferring or converting.
