RFB AOC 27B2H 27"FHD IPS Monitor
68.6 cm (27")
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)
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.
Maximum refresh rate
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.
Display number of colours
16.78 million colors
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.

Horizontal scan range
30 - 83 kHz
Vertical scan range
50 - 76 Hz
Viewable size, horizontal The viewable size is often somewhat smaller than the actual size of a monitor, because there is a border around the image.

sRGB coverage (typical)
Adobe RGB coverage
AMD FreeSync The product includes AMD Freesync Technology for the dynamic synchronization of the graphic card and the monitor in order to avoid screen tearing.
Low Blue Light technology
Market positioning Under which category can the device be positioned in the market, e.g. camera phone.
Feet colour The colour of the feet, which are the projecting part on which a device/piece of furniture, or each of its legs, stands.

RoHS compliance The Restriction of Hazardous Substances (RoHS) Directive aims to restrict certain dangerous substances commonly used in electrical and electronic equipment. Any RoHS compliant product is tested for the presence of Lead (Pb), Cadmium (Cd), Mercury (Hg), Hexavalent chromium (Hex-Cr), Polybrominated biphenyls (PBB), and Polybrominated diphenyl ethers (PBDE). PBB and PBDE are flame retardants used in several plastics. For Cadmium and Hexavalent chromium, there must be less than 0.01% of the substance by weight at raw homogeneous materials level. For Lead, PBB, and PBDE, there must be no more than 0.1% of the material, when calculated by weight at raw homogeneous materials. Any RoHS compliant component must have 100 ppm or less of mercury and the mercury must not have been intentionally added to the component. In the EU, some military and medical equipment are exempt from RoHS compliance.

Ports & interfaces
Built-in USB hub Whether or not the device features a USB hub to connect more than one other device via USB.
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.
HDMI 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.
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.
Headphone connectivity How headphones connect to a device e.g. wirelessly or via a cable and connector.
Cable lock slot Holes on the edge of devices through which a cable lock can be passed, so the device can be locked to a desk etc.
