Dell U2211H 21 inch Monitor - Specs

Traditional TVs have an aspect ratio of 4:3 (squarish), which represents the ratio of the width of the screen to the height. Widescreen TVs have an aspect ratio of 16:9 (also known as "letterbox", a rectangular shape). If you plan to watch a lot of DVD movies on your TV, you might want to consider a widescreen TV, as many DVDs support the 16:9 aspect ratio. If you have a widescreen TV and are viewing standard programming, the picture will appear in letterbox format, meaning that the picture will appear with black boxes on either side or the top and bottom of the screen.

Brightness, also known as luminance or photometric brightness, is the luminance intensity of any surface in a given direction. It is measured per unit of projected area of the surface as viewed from a single direction.

Color depth is how many colors a PDA is able to display. The more colors, the crisper the image will appear.

Contrast Ratio is the difference between the whitest white and the darkest black colors the display can show. The greater the contrast, the better the screen and the subtlety of colors it can display.

Dot pitch is a measurement used to describe the quality of the display. The lower the number, the sharper the image and vice versa.

Maximum Screen Resolution indicates the maxiumum possible sharpness and clarity of an image that a monitor can display, measured in number of dots (pixels). For example, a screen with a resolution of 640 x 480 pixels can display up to 640 distinct dots on each of 480 lines, or about 300,000 pixels. The resolution translates into different dots per inch (dpi) measurements depending on the size of the screen. For example, a 15-inch VGA monitor (640 x 480 pixels) displays about 50 dots per inch. The higher the monitor's resolution, the greater the sharpness and clarity.

Displays come in a few different types. A standard CRT is the most common type of monitor and widely used. They are also the most cost-effective. LCD and TFT monitors have a flat tube so they take up less desk space. They are more expensive than CRTs, but have recently dropped in price.

Response Time is an attribute that applies to LCD monitors. It translates to the amount of time it takes for a liquid crystal cell to go from active (black) to inactive (white) and back to active (black) again. It is measured in milliseconds or (ms). Lower numbers mean faster transitions (eg. 16 ms is faster than 25 ms.) and therefore less visible image artifacts.

Analog Video Inputs, which also may be known as D-Sub inputs, allow a monitor to receive analog (VGA) video signals. Analog inputs accommodate connectors with three rows of pins, with a total of 15 pins. With a higher the number of Analog Video Inputs, more analog input devices can be connected to the monitor.
