You would think such a question would be relatively simple to answer. However, it would seem that the standard aspect ratio and resolution have yet to be set.
More info at Digi Times.To date, only three notebooks have been released with a 14-inch widescreen display, and they all use a 14.0-inch screen with 1280×768 pixels (15:9 aspect ratio). However, the coordinators of one of the bodies involved in defining standards for the industry is proposing the standard should be a 14.1-inch screen with a 16:10 aspect ratio (at resolutions of 1280×800, 1440×900 pixel, 1680×1050 and 1920×1200), and sources suggest that notebooks adopting this size should be available soon.
