+ Configuring your PC for cable TV output
To configure your PC for TV output, do the following: Right-click on a blank part of your desktop and select Properties.
Select the Settings tab. If your TV is properly connected as a second monitor, Windows will recognize this and show two monitor icons, numbered 1 and 2.
Change the Screen resolution by moving the slider all the way to the left.
Enabling External Monitor
Press the Function (FN) key and your computer’s corresponding F-number key — the external monitor key. (This may be FN+F2, F3, F4, F5, F6 or F7; the combination will depend on your computer.)
+ Connecting a laptop to a digital projector
Connect the projector cable to the laptop cable, then turn them both systems on. The projector should automatically display what is on your computer screen. You can switch between Laptop only, Projector only or Projector and Laptop modes. To do this hold down the FN (function) key and press F4 (on some laptops this is F10. Look for the proper icon).
+ Changing your screen resolution
Open up your PC’s “Control Panel” Start > Settings > Control Panel Double click the “Display” icon. Select the “Settings tab”, and then you will see the area to control and “Apply” the new resolution.
