Screen size (inches)

The size of a display is typically indicated by the distance (in inches) between two opposite corners. One problem with this method is that no distinction is made between aspect ratios although the area decreases with the same diagonal the less square the display is. For example, a 21" 4:3 aspect ratio display has an area of approximately 211 square inches, while a 16:9 21" monitor has an area of only approximately 188 square inches.

Image resolution

Image resolution is a colloquial measure of the image size of a raster graphic. It is indicated by the total number of pixels or by the number of columns (width) and rows (height) of a raster graphic.

Colour depth

The color depth determines an essential property of raster and vector graphics: the differentiation of all brightness and color values.
The maximum possible number of (color) gradations is given in bits and thus designates the color depth of an image. These gradations represent a scale on which the actual color information is stored. The color depth is therefore the mathematical basis of the actual color information. In practice, an image never has the amount of colors that the range of this scale (color depth) provides.

A color depth of 1 bit would mean that in one color channel (usually red, green and blue on the computer screen) exactly two states would be possible. As an example, this would be black and red for the color channel red. With a color depth of 2 bits 4 states would be possible, for example black, dark red, medium red and light red. With the usual color depth of 8 bits, 28 = 256 states and thus just as many individual red tones are possible.

Pixel pitch

Pixel pitch is a specification for a computer display or other pixel-based device that describes the distance, for example, between dots (sub-pixels) of the same color on the inside of a display screen. In the case of a color display dot pitch is a measure of the size of a triad plus the distance between the triads.

Tiltable

Capable of being inclined.

VGA

A VGA connector as it is commonly known (other names include RGB connector, D-sub 15, mini sub D15 and mini D15) is a three-row 15 pin DE-15. There are four versions: original and DDC2 pinouts, the far older and less flexible DE-9 connector, and a Mini-VGA used for laptops.
The common 15-pin VGA connector found on most video cards, computer monitors, and other devices, is almost universally called "HD-15". HD stands for "high-density", which distinguishes it from connectors having the same form factor but only 2 rows of pins. However, this connector is often incorrectly referred to as a DB-15 or HDB-15.[citation needed]
"VGA connectors" and their associated cabling are almost always used solely to carry analog component RGBHV (red - green - blue - horizontal sync - vertical sync) video signals along with DDC2 digital clock and data.
Where size is a constraint (such as laptops) a mini-VGA port can sometimes be found in place of the full-sized VGA connector.

HDMI type A receptacle

The High-Definition Multimedia Interface (HDMI) is a compact audio/video connector interface for transmitting uncompressed digital streams. It represents a digital alternative to consumer analog standards such as Radio Frequency (RF) coaxial cable, composite video, S-Video, SCART, component video, D-Terminal, and VGA.

DisplayPort

DisplayPort is a digital display interface standard (approved May 2006, current version 1.1a approved on January 11, 2008) put forth by the Video Electronics Standards Association (VESA). It defines a new license-free, royalty-free, digital audio/video interconnect, intended to be used primarily between a computer and its display monitor, or a computer and a home-theater system.

Power consumption (standby)

In electrical engineering, power consumption refers to the electrical energy over time that must be supplied to an electrical appliance to maintain its operation. The power consumption is usually a result of power used to perform the intended function of the device plus additional "wasted" power that is dissipated as heat, vibration and/or electromagnetic waves.
