This app does not work well, way too much lag, stay away, don't waste your money – iDisplay Review

I thought this would be the solution to working only with a laptop screen, giving me a boost in display real estate as well as productivity, silly me. My gut instinct told me to steer clear, and the shocking price twisted my insides into a knot. Despite this, my teeth gnashing, and flecks of foam forming at the corners of my mouth I pulled the trigger. After much evaluation I have to report that this APP does not have the ability to display anything except notepad and have a reasonable refresh/update/lag time. Try and move a browser or other application into the display and it never updates. Never. It should get zero stars. You have been warned.
