E.g. MacBook Pro 15" (June 2009)
Dual-Link DVI adapter - required if using resolution higher than 1920 x 1200, e.g. 30" monitor. For (e.g. modern variants, 2009-) of MacBook, MacBook Pro, and Mac Mini.

Examples:
1 | A modern 2560x1440 27" monitor (watch out the the 1080 HD screens...) has 60% more pixels than a 1920x1200 24" screen |
2 | The same 2560x1440 27" monitor has 78% more pixels than a 1080 HD screen |
3 | A 1920x1200 WUXGA has 125% more pixels than a 1280x800 WXGA screen |

Ok, the higher-resolutions 27" screens from (e.g.) Apple and Dell come with a higher price tag but don't buy cheaper 1080 HD screens even it's a "27 in big screen". The increased number of pixels of 1440p / 2560x1440 makes a huge difference for professional work.

Example: A standard 15" Mac laptop has 1296000 pixels and adding a 24" external monitor gives a total of 3600000 pixels, and increase by 178%.
