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.

HDR expands the contrast ratio (peak luminance and minimal black levels) and color palette to achieve more details across the whole image - from the darkest parts to the brightest ones, which results in more realistic and life-like image.

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.

The operating temperature shows the safe temperature range (from minimum to maximum), within which the display will function flawlessly. Outside this range it might operate improperly and/or fail entirely.

The software instructions are performed by the CPU cores. The higher number of cores allows for the parallel (simultaneous) processing of more instructions and achieving higher performance. There are various processors equipped with 1, 2, 4, 6, 8, and more cores.

Information about the available connectivity ports, slots and interfaces such as USB, infrared port, SD card slot, audio/video and network interfaces, etc.

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.

The energy efficiency class/label provides general idea about the power consumption. There are different energy efficiency classes and each sets its own requirements regarding the power consumption. Some of the existent energy efficiency classes are A+++, A++, A+, A, B, C, D, E, F, G.

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.

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 frame interpolation value as provided by the manufacturer. This value must not be confused with the refresh rate of the screen.

Display: 42.5 in, LED, 3840 x 2160 pixelsViewing angles (H/V): 178 ° / 178 °Dynamic contrast: 1000000 : 1Refresh rate: 50 Hz / 60 HzFrame interpolation: 800 AM (Active Motion)TV tuner: DVB-T, DVB-T2, DVB-C, DVB-S, DVB-S2, Analog (NTSC/PAL/SECAM)Cores: 2Dimensions: 961.9 x 558.1 x 94.8 mm

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.

Advanced Illumination LED Pattern Projectors are compact illuminators designed for applications requiring structured illumination. These illuminators can be used with any C-mount compatible imaging lens and negatively patterned 21mm reticle to achieve specific structured illumination geometries. When used without a reticle, these illuminators can be adjustable spotlights. Advanced Illumination LED Pattern Projectors are ideal for 3D reconstruction and mapping. The illuminators are available in blue, green, red or white.

Some manufacturers name commercially the measurement unit of their own interpolation technologies as to denote the degree of interpolation. Very often the measurement unit is an abbreviation of the frame interpolation technology in use.

Most displays have the ability to be tilted forward and backward as to provide a more comfortable viewing position for the user.

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.

The speaker is a device, which converts electrical audio signals into acoustic vibrations resulting in corresponding sounds.

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.

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.

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 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.

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.

The operating systems of the smart TV sets feature user interface technologies for navigation and other ways of interaction with the smart TV - installing applications, internet browsing, video calls, sharing content with other users, playing videos and music, etc.

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

Information about the network technologies and standards supported by the model, which allow for it to connect to and communicate with other devices.

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