AMX Device Discovery is a technology developed by AMX to facilitate AMX control systems for easy operation of the target equipment. Epson have implemented this protocol technology, and have provided a setting to enable the protocol function (ON).

The ratio between an image's length and its height. Screens with a horizontal:vertical ratio of 16:9, such as HDTV screens, are known as wide screens. SDTV and general computer displays have an aspect ratio of 4:3.
A method that separates the video signal into a luminance component (Y), and a blue minus luminance (Cb or Pb) and a red minus luminance (Cr or Pr).
A method that combines the video signal into a luminance component and a color component for transmission down a single cable.
The relative brightness of the light and dark areas of an image can be increased or decreased to make text and graphics stand out more clearly, or to make them appear softer. Adjusting this particular property of an image is called contrast adjustment.
An abbreviation of Dynamic Host Configuration Protocol, this protocol automatically assigns an IP addressgto equipment connected to a network.
This is a server (router) for communicating across a network (subnet) divided according to subnet maskg.
HDCP is an abbreviation for
An abbreviation for
•Vertical resolution of 720p or 1080i or greater (p = Progressiveg, i = Interlaceg)
•Screen aspect ratiog of 16:9
Transmits information needed to create one screen by sending every other line, starting from the top of the image and working down to the bottom. Images are more likely to flicker because one frame is displayed every other line.
A number to identify a computer connected to a network.
Projects information to create one screen at a time, displaying the image for one frame. Even though the number of scan lines is the same, the amount of flicker in images decreases because the volume of information has doubled compared with an interlace system.
An abbreviation for Standard Definition Television that refers to standard television systems which do not satisfy the conditions for HDTVgHigh- Definition Television.
An abbreviation for Simple Network Management Protocol, which is the protocol for monitoring and controlling devices such as routers and computers connected to a TCP/IP network.
