projectors). It contains information about the capabilities of the display, such as supported resolutions,
refresh rates (these are called Detailed Timings), the type and manufacturer of the display device, etc.
After connecting a source to a display (DVI, HDMI, DP), the source reads out the EDID to determine the
resolution and refresh rate of the image to be transmitted.

must have CEA extension, but not all devices with CEA extension are HDMI capable.

Solution: If you want to see the image on both displays, you need to select the resolution of the smaller
display (in this case SXGA), otherwise the smaller display may not show the higher resolution
image.

Each DVI sink (e.g. monitors, projectors, plasma displays, etc...) 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 uses EDID data structure to identify the monitor type
and capabilities. Most DVI sources (VGA cards, set top boxes, etc.) will output DVI signal after accepting the

output DVI video signal.
Lightware devices provide the Advanced EDID Management function that helps system integration. The
built-in EDID Router can store and emulate factory pre-programmed- and User programmable EDIDs. The
EDID of the attached monitors or projectors for each output are stored in a non-volatile memory. This way
the EDID of a monitor is available when the monitor is unplugged or switched off.

the Lightware device can be set up to emulate a sink device, which is connected to one of the outputs. In
this case, the EDID automatically changes, if the monitor is replaced with another display device (as long as
it has a valid EDID).
EDID is independently programmable for all inputs without affecting each other. All inputs have their own
EDID circuit.
INFO:  The user is not required to disconnect the video cable to change an EDID as opposed to other
