You'll get distortion when the video adapter resolution is set to a resolution with a 3:4 aspect ratio (800 x 600, 1024 x 768, etc) and stretch mode is enabled in the BIOS. With a 1024 x 768 video mode, stretching maps the 1024 horizontal pixels to 1152 LCD panel pixels to match the 1152 x 768 (6:9) panel's resolution. Drawing a square produces a rectangle on the display. You see the same effect on HighDef TVs with a 6:9 aspect ratio that display a normal 3:4 broadcast. Commonly recognizable objects (people especially) look squashed.

With stretching off, the panel displays the screen as-is, producing (1152 - 1024) / 2 = 64 pixel side bars.

LCD panels exhibit bluriness when the size of a pixel produced by the video adapter doesn't match the size of panel pixel. CRTs don't have this problem, the phosphor dots on the screen automatically interpolate a changing electron beam's intensity. An LCD panel pixel however can only display one distinct color. When the video adapter generates 1024 pixels and the LCD panel controller needs to illuminate 1152 pixels, the controller must interpolate the video signal. Occasionally, one video pixel illuminates 2 LCD panel pixels. Actual interpolation algorithms in the LCD panel controller are a bit more refined than that though. The higher the native resolution of the panel, the less noticeable this blurring. While an interpolated resolution can look quite acceptable, switching back and forth between an interpolated resolution and the native resolution can show a remarkable improvement in sharpness and contrast.
