1024x768 resolution is completely unacceptable

I literally just bought this app, got everything installed and it connected perfectly... Then I noticed that my iPad pro is stuck displaying in 1024x768 resolution... everything is cropped and looks terrible. They said its windows 10 compatible, but I guess thats just not correct... Dont waste your $15 unless they fix it...

a Fan! about iDisplay, v3.3.0
