I need some advice on using my iPad as a second screen for my MacBook Pro. I have two options: Luna Display and Sidecar. Luna Display is a wireless device that connects the iPad to the Mac via Wi-Fi or USB, while Sidecar is a software feature of macOS Catalina and later that works with compatible iPads.

How do they compare in speed, stability, compatibility, and functionality? Has anyone tried both and can share their experience? What are the advantages and disadvantages of each option? Which one do you prefer and why?

Also, what is touchbar on iPad screen? How does Luna Display's LIQUID technology work? Does it really make a difference in image quality and latency? How does Sidecar handle touch input and Apple Pencil support? Can I use either option with any Mac or iPad model?

For more information from Astropad, you can check out this link: Luna Display vs. Apple Sidecar
or this table:

I appreciate any input. Thanks!

Why not just try Sidecar yourself? You have the hardware, and it’s free. If it doesn’t do what you want, consider investing in Luna.
