Back in the early 90's I had a "Sony News" newspaper layout monitor with hardware that displayed a full 2-page newspaper spread at 16 grey-levels. I got addicted and mourned the loss of viewing giant amounts of source code and terminal/app windows. When 4K came out, my dream returned. I'm currently working with four 4K monitors, no scaling, that is also Input Director linked to a second system with two more unscaled 4K monitors, but those are portrait (tall). I'm in heaven, again.
