Each DVI sink (e.g. monitors, projectors, plasma displays, and switcher inputs)

must support the EDID data structure. Source BIOS and operating systems are

likely to query the sink using DDC2B protocol to determine what pixel formats and

interface are supported. DVI standard makes use of EDID data structure for the

identification of the monitor type and capabilities. Most DVI sources (VGA cards,

set top boxes, etc.) will output DVI signal after accepting the connected sink's EDID

information. In case of EDID readout failure or missing EDID the source will not

output DVI video signal.

DVI-TP-TX200DL provides Lightware's Advanced EDID Management function that

helps system integration. It stores and emulates 99 EDID plus the EDID of the

display device which is connected to Monitor Output. Memory addresses from 01 to

50 are factory presets, while memories from 51 to 99 are user programmable. DVI-

TP-TX200DL stores the EDID of the monitor or projector connected to Monitor

Output in a non-volatile memory.

The EDID emulated on the input can be copied from the DVI-TP-TX200DL's

memory (static EDID emulation) or from the attached monitor (dynamic emulation).

For example, the DVI-TP-TX200DL can be set up to emulate the device, which is

connected to MONITOR OUTPUT, and the EDID automatically changes if the

monitor is replaced with another display device (as long as it has a valid EDID).

Info

The user is not required to disconnect the DVI cable to change an EDID as

opposed to other manufacturer's products. EDID can be changed even if a source

is connected to the input and it is powered ON.

2.6.

DVI-TP-RX100DL reclocks the signal on its output using Lightware's sophisticated

TMDS Reclocking technology. Signal reclocking is an essential important

procedure in digital signal transmission. After passing the reclocking circuit, the

signal becomes stable and jitter-free, and can be transmitted over more equipment

like processors and event controllers. When transmitting the signal through long

cables without reclocking on the receiver side, sparkles, noise and jaggies can be

seen on the image.

Info

TMDS stands for Transition Minimized Differential Signaling. It is the electrical and

encoding specification used by the DVI standard for the transmission of the video

signal.

resolution but nothing happens."

Some graphics cards and video sources read out the EDID only after

power-up and later they don't sense that EDID has been changed. You

need to restart your source to make it read out the EDID again.

EDID. I would like to be able to choose from different resolutions, but

my source allows only one resolution."

Most Lightware factory preset EDID allow only one resolution, forcing

the sources to output only that particular signal. You need to select the

Universal EDID (address 49). It supports all common VESA resolutions.

Additionally it also features audio support.
