The type of technology used in the display.

Response time is how long it takes for a display to change the state of pixels, in order to show new content. The less time it takes to respond, the less likely it is to blur fast-changing images.

The size of the screen (measured diagonally).

Resolution is an essential indicator of a screen's image quality, representing the maximum amount of pixels that can be shown on the screen. The resolution is given as a compound value, comprised of horizontal and vertical pixels.

Pixel density is a measurement of a screen's resolution, expressed as the number of pixels per inch (PPI) on the screen. A higher pixel density translates into more clarity and sharpness for the images rendered on the screen, thus improving the quality of the viewing experience.

The type of adaptive synchronization technology supported.

Anti-glare helps to reduce the external reflections of light coming from outside the display.

The frequency at which the display is refreshed (1 Hz = once per second). A higher refresh rate results in smoother UI animations and video playback.

Horizontal viewing angle is the maximum angle at which a display can be viewed with acceptable visual performance.

The type of monitor.

Total tilt adjustment is the ability for the monitor head to move up and down. Tilt adjustment enables a user to change the viewing position of the display, creating a more comfortable view of the screen.

A swivel stand allows you to adjust the position of the display left or right, so you can position it to the desired angle.

The VESA mount is a standard used by most manufacturers. A device that supports the VESA mount can be mounted on many different supports, from arms to wall mounts.

The height represents the vertical dimension of the product.

The width represents the horizontal dimension of the product.

The thickness (or depth) of the product.

We consider a lower weight better because lighter devices are more comfortable to carry. A lower weight is also an advantage for home appliances, as it makes transportation easier, and for many other types of products.

The screen can be turned into portrait mode which is better to view isolated images like documents, photos, etc.

A nit is a measurement of the light that a display emits, equal to one candela per square meter. Brighter displays ensure a screen's contents are easy to read, even in sunny conditions.

A properly calibrated screen represents colors as they are and i.e. you can conduct a photo shoot while verifying your photos in real time. An internal sensor and/or colorimeter is usually included for trouble-free calibration.

Number of colors that a display can accurately reproduce.

Bit depth is the number of bits used to indicate the color of a single pixel. The more bits, the more color range a panel displays. An 8-bit panel uses 256 levels per channel and displays 16.7 million colors, while a 10-bit one reaches 1024 and displays 1.07 billion colors.

Contrast ratio is the visual distance between the lightest and the darkest colors that may be reproduced on the display. A high contrast ratio is desired, resulting in richer dark colors and more distinctive color gradation.

This shows the percentage of Adobe RGB covered by the device.

The percentage of the sRGB color space that the device covers. sRGB is an RGB color space that HP and Microsoft created to use on monitors, printers, and the Web.

More HDMI ports mean that you can simultaneously connect numerous devices, such as video game consoles and set-top boxes.

Thunderbolt is a connection over cable that carries both data and display signals over a single cable, while simultaneously providing power.

Allows you to connect to a display using DisplayPort.

With a standard mini jack socket, you can use the device with most headphones.

Devices that have a DVI connector (usually computers and notebooks) can be connected to the TV set.

With more USB ports, you are able to connect more devices.

Newer USB versions are faster and have better power management.

The USB Type-C features reversible plug orientation and cable direction.

Newer versions of HDMI support higher bandwidth, which allows for higher resolutions and frame rates.

How much power the device consumes when it's switched on.

The power consumption in standby mode, also called energy-saving mode, measures the amount of power the device consumes when shut down but still plugged in.

The more power per year a device consumes, the less energy efficient it is, making it more costly over time.

Devices supporting PiP and PaP - Picture in Picture can show two images from different sources at the same time by splitting the viewing window or creating a smaller window inside the bigger image.

Devices with stereo speakers deliver sound from independent channels on both left and right sides, creating a richer sound and a better experience.

Devices with built-in smart TV features (such as Android TV or webOS) allow you to access popular streaming apps without the need to purchase/connect a separate smart TV device.

A remote control allows you to control the device remotely. The remote control can be included or optional.

If the device supports Dolby Digital it can deliver up to six different audio channels (sides) for a much better sound quality.

If a device supports Dolby Digital Plus it can deliver up to fourteen different audio channels (sides) with improved bitrates, for a much better sound quality.

DTS Surround is a high-quality audio codec that supports up to six audio channels, with good bitrates and audio quality.

An ambient light sensor adjusts the luminance of the device according to the amount of natural light that surrounds it.

A front camera, also called secondary camera, can be used for video chats/selfies.

You can output high definition video and audio to a display. This could be through an HDMI port, Mini HDMI port, or a USB-C port that supports HDMI.

Devices with height adjustment provide a full range of height possibilities resulting in maximum comfort.

A curved screen is designed to better fill a user's field of vision, giving the viewer a sense of being immersed in the image. As our eyes have a natural curvature, these displays can also help to reduce eye strain.

BFI - Black Frame Insertion means that the display will add black frames between real frames in order to help the human eye better perceive the image.

All DLNA-certified products are compatible with one another. When different devices are connected to the same network, data can be transferred easily between them.

More audio input ports mean that more audio devices such as microphones and keyboards can be connected at once.

It supports displaying 3D images from devices such as a 3D-compatible Blu-ray player, allowing you to watch films in 3D when using suitable glasses.

A child lock enables adults to prevent or restrict children’s use of the device.

The device can display 3D images without the need for wearing special glasses. The display's special construction allows viewers to get a sense of an image's depth by tailoring its position to fit the user's perspective.
