Display brightness (typical) Display brightness, measured by its Luminance, presented as a figure in candela per square meter (cd/m2). Typical brightness ratings for monitors range from 250 to 350 cd/m2 with a target value of between 80 to 120 cd/m2 being suitable for most displays in a normal viewing environment.
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.
1920 x 1080 pixels
Native aspect ratio The aspect ratio is the ratio of the width of an image to its height. The native aspect ratio is the one which the projector/display is particularly designed for. Images shown in native aspect ratio will utilize the entire resolution of the display and achieve maximum brightness. Images shown in other than native aspect ratio will always have less resolution and less brightness than images shown in native aspect ratio.
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.)
Supported graphics resolutions The graphic resolutions that can be displayed by the device. The graphic resolution describes the width and height dimensions of a display, such as a computer monitor, measured in pixels.
1920 x 1080 (HD 1080)
Aspect ratio The aspect ratio is the ratio of the width of a shape to its height. For example, 4:3 is common for standard displays and 16:9 is the ratio for Widescreen TV.
Contrast ratio (typical) The difference in light intensity between the brightest white and the darkest black.
Contrast ratio (dynamic) A property of a display system, defined as the ratio of the luminance of the brightest color (white) to that of the darkest color (black) that the system is capable of producing.
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.

USB Type-A downstream ports quantity
VGA (D-Sub) ports quantity Number of VGA (D-Sub) ports (connecting interfaces) in the device. The VGA (D-Sub) connector is a 15 pin connector between a computer and a monitor. It was first introduced in 1987 by IBM.
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-D 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-D means DVI digital, which means it can only support digital, but not analog.
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.
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.
HDCP High-bandwidth Digital Content Protection (HDCP) is a form of digital copy protection to prevent copying of digital audio and video content as it travels across connections.
