2.3 million pixels of perfection.
With the high-resolution LED-backlit widescreen display on the 17-inch MacBook Pro, you get desktop-quality color in an Apple notebook for the first time. The moment you open your MacBook Pro, youre greeted instantly by full, corner-to-corner screen brightness. The 1920-by-1200-pixel resolution (133 pixels per inch) means you can view more palettes and windows or watch HD video in its native 1920-by-1080 resolution. Perfect whether youre working in the studio or out in the field, the display offers a 60 percent greater color gamut than previous generations for richer, more vibrant colors and a 700:1 contrast ratio that makes whites brighter and blacks blacker. In addition, the seamless glass enclosure makes the display stronger and more durable. Because its power efficient and the glass is mercury- and arsenic-free, its greener than ever. And now you can choose a standard glossy display or an optional antiglare display, depending on your needs.
That sounds - to me - like you get the newer gamut screen but anti glare.
