1280x800 (16:10) widescreen wallpapers for notebook computer with 12.1-inch, 13.3-inch, 14.1-inch or 15.4-inch widescreen LCD monitors.
Widescreen is becoming the norm against standard aspect ratio in notebooks, partially because a widescreen will effectively add a lot more reading space to a screen with a minimal amount of increase in size. More than that, widescreen is fairly logical for humans, since our eyes are not jammed right next to each other.
