Apple Sidecar is helpful—but not perfect. If you’ve ever had it disconnect, lag, or simply not work on your device, you’re not alone. Many users are looking for reliable Sidecar alternatives to use their iPad (or other device) as a second screen.
Here are the top second monitor apps in 2025—and why Duet Display is the best pick for most users.
Why Look Beyond Sidecar?
Sidecar is limited to newer Apple devices and requires the same Apple ID. It also:
- Doesn’t support Windows
- Can be laggy with large files
- Sometimes won’t connect or stay connected
- Doesn’t support business or mixed-device setups
If you want more flexibility, performance, or platform support, check out these alternatives.
Best Sidecar Alternatives in 2025
1. Duet Display – Best Overall
- Works with Mac, Windows, iOS, and Android
- Wired + wireless modes for low-latency use
- Touchscreen and Apple Pencil support
- Great for remote work, education, and creative pros
- Options for individuals and teams (Duet Business)
Why we recommend it: Duet is built by ex-Apple engineers to solve Sidecar’s biggest flaws—and it shows.
2. Astropad Studio – Geared toward Artists
Great Apple Pencil support, but only for Mac users and not ideal for general second screen use.
3. Luna Display – Best Hardware Option
Uses a dongle to extend displays. Reliable but pricey and lacks cross-platform support.
4. Splashtop Wired XDisplay – Budget-Friendly
Free and wired, but less stable and no touch input support.
Final Thoughts: Duet Is the Best Sidecar Alternative
If Sidecar isn’t cutting it, Duet Display gives you more compatibility, smoother performance, and the ability to work across Mac, PC, and mobile.
Whether you’re a student, creative, or remote worker—Duet turns your iPad into the second screen you actually wanted.
