Posted this b/c I'm surprised to learn that the much-ballyhooed $699 Dell 4K monitor maxes out at 30Hz refresh rates when running at full resolution (3840x2160), even if you have a DisplayPort 1.2 card capable of pushing that many pixels at 60Hz.
... just cancelled my order.
I was thinking about ordering and I need accurate color.
Now I'll wait until the color is accurate before ordering the 4k monitor.
