What third-party apps are best for using an iPad Pro as a second monitor

Duet Display

**Duet Display is often considered the best app for turning an iPad into a second monitor. Developed by ex-Apple engineers, it offers high performance and display quality with zero lag, making it ideal for multitasking and productivity. The app supports both wired and wireless connections, with the latter available through the Duet Air plan, which costs $48 per year. Duet Display allows you to interact with your computer using touch and gestures on your iPad, including two-finger scrolling and zooming. Additionally, Duet Pro offers features like pressure and tilt sensitivity for artists using the Apple Pencil[1][9].

Splashtop Wired XDisplay

**Splashtop Wired XDisplay is another popular option, especially for those on a budget. It requires a USB connection to work and is available for free on iOS, though there is a $7 charge for the Android version. While it may not be as smooth as Duet Display, it provides a decent experience with some noticeable latency. It's a good choice for those who don't need advanced features but want a basic second monitor setup[1].

Air Display

**Air Display is another app that allows you to use your iPad as a second monitor. It supports both Mac and Windows computers and offers a smooth experience, even over wireless connections. However, it has seen fewer updates since macOS Catalina, which introduced Sidecar, a built-in feature for using iPads as second screens on Macs. Air Display costs $9.99 and also supports Android devices[4][11].

Luna Display

**Luna Display is a hardware-based solution that turns your iPad into a second monitor for your Mac. It offers a seamless experience but is more expensive than software solutions. It's ideal for those who prefer a dedicated hardware setup rather than relying on apps[4].

Each of these apps has its strengths and weaknesses, depending on your specific needs and preferences. Duet Display offers the best performance but at a higher cost, while Splashtop Wired XDisplay is more budget-friendly but with some limitations. Air Display provides a smooth wireless experience, and Luna Display offers a hardware-based solution for Mac users.
