Nice app!

Have been using TwoMon for a while, with Windows 7 and a 2012 iPad, and currently with an iPap Air 2 and Windows 10. Very happy with it. Works great. Sometimes it can be laggy, but that has been usually a conflict with some other app on the PC side of things. Most annoying thing is having to install iTunes on the PC to connect the iPad (I don’t use iTunes), but there are drivers you can install so the iPad is recognized by Windows without having to install the entire iTunes app (and yes, this is an Apple thing, not MS). Thumbs up TwoMon!

Look no farther for a windows extended monitor solution. This is a *great* app and works well on wifi or USB. I own them both. My Ipad Pro 12.9 works perfectly. Great resolution options (I like 1280x1024 on my 12.9 pro), great options for using ipad to make a nearly native touch solution for windows! Tremendous value and you can use an older Ipad 1 or 2 too.

USB works great

I just bought USB and am very pleased. I was using Duet, but they couldn’t get it to work with Win10. Twomon has more features though. I would like to use Twomon Air. I am having a connection problem. I’ll figure it out.
