Can iPad Be Used as a Monitor A Practical Guide for Creators
Explore how to turn an iPad into a second display, when to use Sidecar, and how third party apps can extend your workflow across Mac, Windows, and more.
iPad as a monitor refers to using an iPad as an external display to extend or mirror another device's desktop. It is not a replacement for the iPad’s own screen.
What It Means to Use an iPad as a Monitor
Using an iPad as a monitor means treating the tablet as an external display for another device's desktop. It can be used to extend your workspace or simply mirror what’s on the primary screen. For many creators and productivity users, this setup lets you keep reference material, palettes, chat apps, or code on the iPad while you work on a larger screen. According to Tablet Info, the practicality of this approach depends on the ecosystem you’re using (Mac versus Windows or other devices) and the level of latency you’re willing to tolerate. The iPad’s high resolution and touch capabilities add value when the display is used for drawing with an Apple Pencil or for touch-enabled workflows, but they also introduce considerations around color accuracy, refresh rate, and frame timing. This guide explains the options, setup steps, and best practices so you can choose the method that fits your workflow.
Native Options With Mac: Sidecar and Universal Control
If you’re in the Apple ecosystem, macOS Sidecar is the built-in way to use an iPad as a second screen. You can extend or mirror your Mac desktop, drag windows to the iPad, and even draw with Apple Pencil in compatible apps. Sidecar works over Wi Fi or USB, but performance improves with a wired connection. Universal Control lets you move your cursor and files between Mac and iPad as if they were one workspace, but it does not turn the iPad into a separate display in the same sense; instead, it creates a seamless cross-device workspace. For best results, ensure both devices are updated and logged into the same Apple ID. This native route offers low latency and deep integration, and it doesn’t require third-party software, but limited to supported macOS and iPadOS versions.
Using iPad as a Monitor for Windows or Other Devices
Windows PCs and other devices do not natively support Sidecar, so you’ll rely on third-party apps. Solutions like Duet Display or Astropad connect the iPad to a Windows or Mac computer to extend or mirror the display. Some apps require a wired USB cable to minimize latency, while others can work over a reliable Wi-Fi network. Always verify system requirements and device compatibility before purchasing. You’ll typically install the companion app on your computer and the companion app on the iPad, then choose the iPad as the target display in the app settings or on your OS. These tools enable real time drawing, coding, or productivity on the larger iPad screen without replacing your main monitor.
Third-Party Apps That Turn the iPad into a Second Screen
There are several popular utilities that transform the iPad into a second display. Duet Display, Astropad, and Splashtop Wired XDisplay are common choices, each with different modes for extend and mirror. Many apps offer tuned settings for resolution, frame rate, and touch input to balance performance and battery life. When evaluating options, consider whether you want wired stability or wireless convenience, how well the app handles high DPI content, and whether it supports drawing with Apple Pencil or stylus input. Some apps also include companion software for Windows or macOS that improves compatibility and reduces lag. Tablet Info suggests trying a free trial when available to gauge performance before committing.
Wired vs Wireless Connections: Pros and Cons
A wired connection through USB-C or Lightning usually delivers lower latency, higher reliability, and better color throughput, making it preferable for real time tasks like video editing or design work. Wireless connections offer freedom of movement and easier setup, but can introduce latency, hiccups, and occasional color shifts depending on network stability. Your choice should reflect your environment: a quiet desk with a fast USB-C cable is ideal for professionals; a laptop-only or couch setup might benefit from a robust Wi-Fi network and a quality wireless display app. Battery usage on the iPad is another consideration: prolonged streaming via wireless ties into charging needs. In all cases, keep the iPad within reasonable range of the host device and avoid congested or crowded networks.
Important Display Considerations: Latency, Color, and Calibration
Latency affects how quickly actions on the host computer appear on the iPad. High latency can disrupt drawing, gaming, or precise editing. Color accuracy and brightness on the iPad may differ from your main monitor, which matters for photo or video work. If color fidelity is critical, look for apps that allow correct color spaces (like P3) and consider calibrating the iPad’s display with built-in tools or external hardware calibrators where available. The iPad’s touch input adds interactivity that is beneficial for certain tasks, but for color-critical work you may want to disable touch input in the app or use a dedicated drawing tablet when possible. Keep an eye on frame rate (60Hz is common) and adjust the host's resolution to avoid overtaxing the connection.
Step-by-Step Setup for Mac with Sidecar
To use Sidecar, update to compatible macOS and iPadOS versions, then sign in with the same Apple ID on both devices. Open the AirPlay menu in macOS and select your iPad from the list. Choose Extend Desktop to turn the iPad into an additional display, or Mirror Display to show the same content. You can arrange the display order in System Settings > Displays. For maximum performance, connect the iPad with a USB-C cable instead of relying on wireless AirPlay. You can customize sidebar and touch bar behavior in the Sidecar preferences. If you’re using Universal Control, simply place the iPad next to your Mac and move your cursor onto it; no separate display is created, but you can drag and drop content directly.
Step-by-Step Setup for Third-Party Apps on Windows or Mac
Install the chosen companion app on the host computer and on the iPad, then launch and follow on screen prompts to connect. Most apps offer USB or Wi-Fi connection options; for USB, you may need a supported cable and the app may prompt you to trust the computer. After pairing, open your display settings to arrange the iPad as an extended or mirrored screen. Adjust resolution and frame rate within the app or OS settings to optimize performance. Ensure you meet system requirements and keep the app updated to minimize lag or compatibility issues. If the connection drops, troubleshooting steps typically include restarting devices, re-pairing, updating drivers, and verifying firewall permissions.
Real-World Scenarios, Pitfalls, and Alternatives
Consider using an iPad as a monitor for reference work or as a drawing surface, rather than as a full replacement for a primary monitor. For coding, design, or video editing, a dedicated large display is still often better. Some pitfalls include touch input interference, increased battery drain, and occasional lag when networks are busy. If you frequently need extra screen real estate, evaluate a traditional external monitor or a dedicated portable display that connects via USB-C. Alternatives include using a dedicated drawing tablet or a portable monitor designed for laptops, which may offer better color accuracy and ergonomics. Tablet Info’s testing across various setups shows that you can achieve satisfying results with careful setup and realistic expectations about latency and color consistency.
