Kelvin(K), of a light source. The higher the color temperature, the
bluer the light. The lower the temperature, the redder the light.
Benchmark color temperature for the A/V industry include 5000°K,
6500°K, and 9000°K.
 "Contrast ratio": The radio of the high light output level divided by
the low light output level. In theory, the contrast radio of the
television system should be at least 100:1, if not 300:1. In reality,
there are several limitations. In the CRT, light from adjacent
elements contaminate the area of each element. Room ambient
light will contaminate the light emitted from the CRT.
Well-controlled viewing conditions should yield a practical
contrast ratio of 30:1 to 50:1.
 "DVI": Digital Visual Interface. The digital video connectivity
standard that was developed by DDWG (Digital Display Work
Group). This connection standard offers two different connectors:
one with 24 pins that handles digital video signals only, and one
with 29 pins that handles both digital and analog video.
 "EDID": Extended Display Identification Data – EDID is a data
structure used to communicate video display information,
including native resolution and vertical interval refresh rate
requirements, to a source device. The source device will then
output the optimal video format for the display based on the
provided EDID data, ensuring proper video image quality. This
communication takes place over the DDC – Display Data Channel.
 "Ethernet": A Local Area Network (LAN) standard officially known
as IEEE 802.3. Ethernet and other LAN technologies are used for
interconnecting computers, printers, workstations, terminals,
servers, etc. within the same building or campus. Ethernet
