How To Switch Between Monitorsby Perry Piekarski ; Updated September 28, 2017
All PCs are capable of connecting to multiple monitors at a single moment. And with the development of LCD TVs and downloadable media, connecting your computer to your television set becomes both easier and more of a necessity. While it's possible to connect your PC to another monitor in order to extend the display and make it larger, you may want your display to appear strictly on the second screen. Thankfully switching between monitors is a breeze and can be done in mere seconds.
Click the "Start" button on the taskbar and open the Control Panel.
Click "Appearance and Themes" and then choose "Display" if you are using Windows XP. On newer versions of Windows, type "Display" into the search bar at the top of the Control Panel window and then click "Display" when it appears. Then click "Change display settings".
Choose the display you want to switch to and click "Apply" to confirm the changes. In newer versions of Windows, click the drop-down box next to "Multiple displays" and choose "Show Desktop only on..." for the corresponding monitor. Then confirm the changes. After confirmation, your computer will now display on the other monitor.
Click the Apple icon on the Desktop and open the System Preferences menu.
Select "Displays" under the "Hardware" section.
Click the "Detect Displays" button. Your Mac automatically detects the additional monitor and "mirrors" it on both your primary and additional monitor. By clicking the "Arrangement" tab, you can further adjust the settings for this feature in the Display menu. Using the "Arrangement tab", you can switch between a mirrored desktop or an extended one.
