left = 16:10 aspect ratio right = 16:9 ratio
The right one turns out to be wider and not as tall.
When moving screens from one to the other, they don't match. If I try to make them match in the resolution of the right to that of the left, I get blurrier display and vertical black bars on the left and right and a smaller display.
I like having matching resolutions for my dual monitors.
This table from http://www.prismo.ch/comparisons/desktop.php is a useful guide.
Desktop LCD Monitor Comparison (Pixel Table)
This table shows the screen resolution, pixel density (pixel pitch in pixels per inch, ppi), size of one square pixel, aspect ratio of the screen, number of pixels (megapixels or MP), and pixel area gain compared to a 1024 by 768 pixel XGA resolution for various display sizes (measured by the viewable diagonal).
