Nice app, with a few kinks

This app works as described by extended your computer display on a second monitor. I used this to add an additional monitor while traveling using my laptop and iPad Pro 12.9 display. The dimensions of the screen as others have mentioned you may have to adjust, but it works well with added benefit of touch screen from the iPad. Only glitch or kink is when connected I can not print documents. Not a major issue but enough of a hassle that I’ve decided to test out a portable monitor for at home and use this app primarily while traveling.

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.
