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.

Aspect ratio

The aspect ratio of an image is the ratio of the width of the image to its height, expressed as two numbers separated by a colon. That is, for an x:y aspect ratio, no matter how big or small the image is, if the width is divided into x units of equal length and the height is measured using this same length unit, the height will be measured to be y units. Aspect ratios are mathematically expressed as x:y.

The kind of the surface of the screen. Examples are glossy or antiglare.

Contrast ratio

The ratio of the intensity of the brightest bright to the darkest dark.

Refresh rate

The refresh rate (most commonly the "vertical refresh rate", "vertical scan rate" for CRTs) is the number of times in a second that a display hardware draws the data. This is distinct from the measure of frame rate in that the refresh rate includes the repeated drawing of identical frames, while frame rate measures how often a video source can feed an entire frame of new data to a display.

For example, most movie projectors advance from one frame to the next one 24 times each second. But each frame is illuminated two or three times before the next frame is projected using a shutter in front of its lamp. As a result, the movie projector runs at 24 frames per second, but has a 48 or 72 Hz refresh rate.

Brightness

Brightness is an attribute of visual perception in which a source appears to emit a given amount of light. In other words, brightness is the perception elicited by the luminance of a visual target. This is a subjective attribute/property of an object being observed.

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.

Viewing angle (H)

In display technology parlance, viewing angle is the maximum angle at which a display can be viewed with acceptable visual performance. In a technical context, this angular range is called viewing cone defined by a multitude of viewing directions.

Viewing angle (V)

In display technology parlance, viewing angle is the maximum angle at which a display can be viewed with acceptable visual performance. In a technical context, this angular range is called viewing cone defined by a multitude of viewing directions.

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.

VESA Flat Display Mounting Interface

The VESA Flat Display Mounting Interface (FDMI) is a standard for mounting flat screens on walls, ceilings, tables or vehicles. Depending on the size and weight of the screen, it has at least 4 threads for screws: Until October 2002, this standardization was known as the Flat Panel Monitor Physical Mounting Interface (FPMPMI).

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.

HDMI version

HDMI devices are manufactured to adhere to various versions of the specification, in which each version is given a number and/or letter, such as 1.0, 1.2, or 1.4b. Each subsequent version of the specification uses the same kind of cable but increases the bandwidth and/or capabilities of what can be transmitted over the cable.

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.

Input voltage

Voltage (sometimes also called electric or electrical tension) is the difference of electrical potential between two points of an electrical or electronic circuit, expressed in volts.

External AC adapter

A linear or switched-mode power supply (or in some cases just a transformer) that is built into the top of a plug is known as a "wall wart", "power brick", "plug pack", "plug-in adapter", "adapter block", "domestic mains adapter" or just "power adapter". They are even more diverse than their names; often with either the same kind of DC plug offering different voltage or polarity, or a different plug offering the same voltage.
