How to Use an iPad as a Second Monitor in Windows
Using your iPad as a second monitor to extend your PC's desktop onto its touch screen creates an ideal parking spot for the content you frequently have to move around your workspace, like cumbersome toolbars or streaming lecture videos. Both Air Display and Splashtop's XDisplay, for example, use your Wi-Fi network to share your desktop's real estate. For a solution that gives you remote access to your PC's desktop from anywhere in the world, try Splashtop's Remote Desktop instead.

- Information in this article applies to PCs running Windows 8 and iPads running iOS 7. It may vary slightly or significantly with other versions or products.
- There are a number of apps and software solutions that promise to stretch your computer's desktop onto your iPad, but be cautious if choosing a solution not listed here. While Air Display and both Splashtop apps are compatible with Windows 8, most other tools only promise to support Windows 7 and prior versions. Be sure to investigate the system specifications before committing to an alternative solution.
- When using Air Display or XDisplay, use your PC's Control Panel -- press the "Windows-X" keys, and then select "Control Panel" from the available options -- to configure your display settings. You can, for example, modify which device is the primary display or adjust the screen resolution.
- While Splashtop developed both the XDisplay and Remote Desktop applications, they are not identical products. XDisplay is designed to extend your desktop to the iPad, but is entirely controlled with your PC's mouse or trackpad. Remote Desktop, on the other hand -- which mirrors your PC's desktop instead of stretching it -- allows you to control your PC using the iPad's touch screen instead of your computer and mouse.
