Most laptops sold today (2008) have a measly XGA (1024x768) display.

Top-end laptops may have as much as QXGA, or quad-XGA, which is double the width and height (in pixels), or 2048x1536.

Many laptops are now coming in "wide-format". The width-height ratio is 16:10 instead of 4:3. For example, WXGA is 1200x768. Most laptops sold today (2008) have a measly XGA (1024x768) display.

The main difference is in the screen resolution (that is, the number of pixels on the screen). The more pixels you have, the more detail the monitor can display. Some standard formats and the number of pixels (width x height) are: VGA: 640 x 480

SVGA: 800 x 600

XGA: 1024 x 768

SXGA: 1280 x 1024

SXGA+: 1400 x 1050

UXGA: 1600 x 1200

QXGA: 2048 x 1536 Another minor difference is the "aspect ratio" which is the ratio of width to height of the screen. Most standard formats have an aspect ratio of 4 to 3, except for SXGA which has a ratio of 5 to 4. Wide screen formats are prefixed by a "W" and have an aspect ratio of 16 to 10 or 16 to 9. For example: WSXGA: 1440 x 900

WSXGA+: 1680 x 1050

WUXGA: 1920 x 1200
