Hi there, I've never seen a 4k monitor screen set up as a working monitor. Would you mind posting a pic somewhere of what it looks like full of application windows? I'd just like an idea of how much I could fit on one. I've been considering about buying a third monitor, but I think that a single larger monitor would be easier to deal with. In my work, I frequently have 10+ windows open for editors, graphics, other references resources, and finally the application I document might need 5-6 of its own.
