|In display technology parlance, viewing angle is the maximum angle at which a display can be viewed with acceptable visual performance. Viewing angle is another important spec that marks the performance a display device. Beyond the viewing angle on either side, the image becomes distorted and lacks colour saturation and contrast. In a technical context, this angular range is called viewing cone defined by a multitude of viewing directions..|
|VESA Standards||Industrial Displays|
|Source:ERGO in Demand|
|The initials, VESA, stands for Video Electronics Standards Association. This is an international non-profit corporation, which represents more than 300 corporate members worldwide. The standards provide specific guidelines of the mounting hole pattern placement, screw size, and guidelines for the mounting pad or mounting apparatus to be utilized by equipment manufacturers based on a the size of the screen and monitor's weight.
A great number of monitors are compliant with the VESA standard. Manufacturers of monitors have agreed on a industry interface standard, which means a hole pattern on the back of the monitor, screen or display that fits any mounting device whether for VESA wall mounts, desktop or ceiling mounts. The following summarizes VESA standard mounting hole patterns that are used today: For smaller and medium flat panels, LCD monitors and screens from 12" to 22.9" diagonal, and falling in a weight range up to 30.8 lbs (14 kg): 75 x 75 mm or 100 x 100 mm (2.95" x 2.95" or 3.94" x 3.94")

|VGA D-sub Connector||General|
|A VGA connector is a three-row 15-pin DE-15 connector. The 15-pin VGA connector is found on many video cards, computer monitors, and some high definition television sets. On laptop computers or other small devices, a mini-VGA port is sometimes used in place of the full-sized VGA connector.
DE-15 is also called RGB connector D-sub 15, mini sub D15, mini D15, DB-15, HDB-15, HD-15 or HD15 (High Density, to distinguish it from the older and less flexible DE-9 connector used on older VGA cards, which has the same shell size but only two rows of pins).
VGA connectors and cables carry analog component RGBHV (red, green, blue, horizontal sync, vertical sync) video signals, and VESA Display Data Channel (VESA DDC) data. In the original version of DE-15 pinout, one pin was keyed and 4 pins carried Monitor ID bits which were rarely used; VESA DDC redefined some of these pins and replaced the key pin with +5 V DC power supply.
