Display resolution The number of distinct pixels in each dimension that can be displayed. It is usually quoted as width × height, with the units in pixels: for example, "1024 × 768" means the width is 1024 pixels and the height is 768 pixels. The higher the number of pixels, the sharper the image.
3840 x 2160 pixels
Display brightness Brightness is the amount of radiating light emitted from the screen. The brightness rating is measured in candellas per square meter, commonly known as 'nits'.
Response time The response time is the time difference between the moment that a source (for example a video card) sends a signal and that equipment (for example a monitor) receives or display the signal. (Used abbreviations: R/F = Rise and Fall.)
Contrast ratio (typical) The difference in light intensity between the brightest white and the darkest black.
Dynamic contrast ratio marketing name
Viewing angle, horizontal Maximum horizontal angle at which a display can be viewed with acceptable visual performance.
Viewing angle, vertical Maximum vertical angle at which a display can be viewed with acceptable visual performance.
Pixel pitch This is the parameter of a picture tube, which specifies the shortest distance between two dots of the same colour. The principle is: the smaller the dot pitch, the better sharpness of image.

Ports & interfaces
HDMI ports quantity The number of sockets (ports) for HDMI connections. HDMI (High-Definition Multimedia Interface) is a compact audio/video interface for transferring uncompressed video data and compressed/uncompressed digital audio data from a HDMI-compliant device ("the source device") to a compatible computer monitor, video projector, digital television, or digital audio device. HDMI is a digital replacement for existing analog video standards.
DVI port Digital Visual Interface (DVI) is a video display interface to connect a video source to a display device, such as a computer monitor.
DVI-I ports quantity This is the amount of DVI-I interfaces. Digital Visual Interface (DVI) is a video display interface developed by the Digital Display Working Group (DDWG). The digital interface is used to connect a video source to a display device, such as a computer monitor. DVI-I is DVI integrated, which means it can support digital and analog.
DisplayPorts quantity Number of DisplayPorts. A DisplayPort is a digital display interface developed by the Video Electronics Standards Association (VESA). The interface is primarily used to connect a video source to a display device such as a computer monitor, though it can also be used to carry audio, USB, and other forms of data.
USB ports quantity
Ethernet LAN An Ethernet LAN (Local Area Network) interface is present, for a wired conection via a cable.
Ethernet LAN (RJ-45) ports Number of Ethernet LAN (RJ-45) ports (connecting interfaces) in the device. Ethernet LAN (RJ-45) ports allow a computer to connect to the ethernet.
