Display
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

Unknown. Help us by suggesting a value. (HP E231)
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.
Adaptive synchronization
Unknown. Help us by suggesting a value. (HP E221)
Unknown. Help us by suggesting a value. (HP E231)
The type of adaptive synchronization technology supported.
Anti-glare helps to reduce the external reflections of light coming from outside the display.
refresh rate
Unknown. Help us by suggesting a value. (HP E221)
Unknown. Help us by suggesting a value. (HP E231)
The frequency at which the screen is refreshed. Higher frequency results in less flickering (less noise) and more natural movement representation in action-intense scenes.
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.
Colors
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.
display colors

Number of colors that a display can accurately reproduce.
bit depth

Unknown. Help us by suggesting a value. (HP E231)
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

Unknown. Help us by suggesting a value. (HP E231)
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.
Adobe RGB coverage

Unknown. Help us by suggesting a value. (HP E231)
The more power per year a device consumes, the less energy efficient it is, making it more costly over time.
Features
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.

audio output power
Unknown. Help us by suggesting a value. (HP E221)
Unknown. Help us by suggesting a value. (HP E231)
Audio output power is based on the number of speakers and their power in watts. High audio output power results in loud, clear sounds.
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.
Miscellaneous
