I can't seem to find a concrete definition of what the cut off point is for a desk top screen size.
There is a report in Adobe Analytics which allows you to breakdown visits by screen size. But I'm having trouble deciphering which screen sizes are from desktop, does anyone know what the cut off point is for a desk top screen size?
I would do a custom implementation to capture both platforms (desktop, mobile web, iOS, Android) and screenSize in all platforms. Use DTM to capture (desktop and mobile web) and proc rule (iOS and Android).
