Name of the company-manufacturer.

Name of the series, which the model belongs to.

Designation of the model.

The year in which this model was announced.

Size class of the display as declared by the manufacturer. Often this is the rounded value of the actual size of the diagonal in inches.

Approximate diagonal size of the display. If the manufacturer does not provide such information, the diagonal is calculated from the width and height of the screen.

Approximate width of the display. If the manufacturer does not provide such information, the width is calculated from the diagonal and the aspect ratio.

Approximate height of the display. If the manufacturer does not provide such information, the height is calculated from the diagonal and the aspect ratio.

There are various panel technologies. Each has its own specific features – viewing angles, color reproduction, response time, brightness/contrast, production cost, etc. The image quality depends directly on the type of the display panel used.

The most widely used panels are those with 6, 8, and 10 bits for each of the RGB components of the pixel. They provide 18-, 24-, and 30-bit color, respectively.

Frame Rate Control (FRC) is a method, which allows the pixels to show more color tones. With quick cyclic switching between different color tones, an illusion for a new intermediate color tone is created. For example, by using FRC, a 6-bit display panel is able to show 16.7 millioin colors, which are typical for 8-bit display panels, and not the standard 262200 colors, instead. There are different FRC algorithms.

The maximum number of colors, which the display is able to reproduce, depends on the type of the panel in use and color enhancing technologies like FRC.

The ratio between the horizontal and the vertical side of the display. Some of the standard and widely used aspect ratios are 4:3, 5:4, 16:9 and 16:10.

Information about the number of pixels on the horizontal and vertical side of the screen. A higher resolution allows the display of a more detailed and of higher quality image.

The pixel pitch shows the distance from the centers of two neighboring pixels. In displays, which have a native resolution (the TFT ones, for example), the pixel pitch depends on the resolution and the size of the screen.

Information of the number of pixels in a unit of length. With the decrease of the display size and the increase of its resolution, the pixel density increases.

The percentage of the approximate area, taken by the active part of the screen, to the total front area.

The backlight is the source of light of the LCD display panels. The type of backlight determines the image quality and the color space of the display. There are various backlights such as CCFL, LED, WLED, RGB-LED, and etc.

sRGB is a color space, developed jointly by Hewlett-Packard and Microsoft in 1996. It is used in different devices such as printers, displays, TV sets, cameras, etc. The sRGB color space covers about 72% of the NTSC color space.

Information about the brightness of the screen. It is measured in candela per square metre (cd/m²).

The static contrast shows the ratio between the brightest and the darkest color, which the display can reproduce simultaneously, for example, within one and the same frame/scene.

The dynamic contrast shows the ratio between the brightest and the darkest color, which the display can reproduce over time, for example, in the course of playing a video.

Information about the maximum horizontal viewing angle, within which the image on the screen is of acceptable quality.

Information about the maximum vertical viewing angle, within which the image on the screen is of acceptable quality.

Information about the minimum amount of time, in which the pixels change from one color to another. Very often the manufacturer provides the response time for transition from grey-to-grey (G2G).

Information about the type of coating of the display. There are different types of matte and glossy coatings, each of which has its own advantages and drawbacks.

Information on whether 3D is supported or not.

The horizontal scan rate/frequency shows the number of horizontal lines, displayed by the monitor per second, when it is plugged to an analog source. In CRT displays the horizontal scan rate is the frequency, at which the CRT moves the electron beam from the left to the right of the display in a cycling manner, thus specifying the number of horizontal lines displayed per second.

The horizontal scan rate/frequency shows the number of horizontal lines, displayed by the monitor per second, when it is plugged to a digital source.

The vertical frequency is also called refresh rate and shows how many times in a second the image on the screen is refreshed.

The vertical frequency/refresh rate shows how many times in a second the image on the screen is refreshed.

Permissible voltage tolerance in a 110-volt electric system.

Permissible voltage tolerance in a 220-volt electric system.

Requirement regarding the alternating current frequency in the electric system.

Information about the colors, in which the specific model is offered to the market.

Information about whether there is a possibility for wall mounting according to the VESA Mounting Interface Standard (MIS).

There are many various interfaces under the VESA standard, which differ in the size of the brackets, the distances between the screw holes and their number.

Information about whether the stand can be dismounted. Usually, this is required for wall mounting.

Information about whether the stand allows height adjustment.

Information about the extent to which the stand allows the height to be adjusted.
