The 27-inch (diagonal) TFT active-matrix LCD has a resolution of 2560 by 1440 pixels, the standard for displays of this size and price. Its 12 ms response time and 16.7 million colors, however, fall short of the 6 ms response time and 1.07 billion colors of Dell's comparable display.

We might be splitting hairs here, but those hairs would be viewed with 1,053,300,000 fewer colors on Apple's display. Just saying.
