I am looking for a gratis program that can allow me to use my iPad as a second monitor for my computer (Microsoft Windows).

I'm aware of:

  • Duet Display: costs between 10 USD for the basic version and 20 USD for the "pro" version. Received 17.4k ratings, and the average rating is 4.3/5.
  • Air Display: costs around 10 USD and ratings aren't positive.
  • iDisplay: costs around 15 USD and ratings aren't positive.
  • Splashtop: costs around 5 USD and ratings aren't positive.

I have crossposted the question at:

You can use spacedesk:

  • gratis for personal use
  • requires the computer and the iPad to be in the same network (e.g., same Wi-Fi network)
  • also works for Android
  • good ratings on Play store and iOS App store but not many ratings.

You can use Splashtop Wired XDisplay HD – Extend & Mirror 4+:

  • gratis but might become non-gratis in the future ("**** LIMITED TIME Launch Special (Regular Price: $19.99 USD)" according to the iOS App store)
  • works with macOS and Microsoft Windows
  • iOS App store ratings: 3.8/5 (186 Ratings)
