2.5. Understanding EDID
2.5.1. Basics
EDID stands for Extended Display Identification Data. Simply put, EDID is the passport of
display devices (monitors, TV sets, projectors). It contains information about the display’s
capabilities, such as supported resolutions, refresh rates (these are called Detailed
Timings), the type and manufacturer of the display device, etc.
After connecting a DVI source to a DVI display, the source reads out the EDID to
determine the resolution and refresh rate of the image to be transmitted.
Figure 2-3. EDID communication
Most DVI computer displays have 128-byte long EDID structure. However, Digital
Televisions and HDMI capable displays may have another 128 bytes, which is called
E-EDID and defined by CEA (Consumer Electronics Association). This extension contains
information about additional Detailed Timings, audio capabilities, speaker allocation and
HDMI capabilities. It is important to know, that all HDMI capable devices must have CEA
extension, but not all devices are HDMI capable which have the extension.
2.5.2. Common problems related to EDID
Problem: „I have changed to a different EDID on an input port of the matrix to have a
different resolution but nothing happens.”
Solution: 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.
Problem: „I have a UMX-OPT-TX150R and I’m using a Lightware factory preset EDID. I
would like to be able to choose from different resolutions, but my source
allows only one resolution.”
Solution: Most Lightware factory preset EDIDs allow only one resolution, forcing the
sources to output only that particular signal. You need to select a Universal
EDID. It supports all common VESA resolutions. Additionally it also features
audio support.

Section 2. General description Page 13 / 107
2.6. Advanced EDID Management
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. HDMI standard makes use of EDID data structure for the identification of the
monitor type and capabilities. Most DVI sources (graphic 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.
UMX-OPT-TX150R provides Lightware’s Advanced EDID Management function that
helps system integration. The built in EDID Router stores and emulates 36 EDID data
plus all monitor's EDID that are connected to the output connectors. There are 20 factory
preset and 16 user programmable EDIDs. The router stores the EDID of all attached
monitors or projectors for the output in a non-volatile memory. This way the EDID from a
monitor is available when the monitor is unplugged, or switched off.
An emulated EDID can be copied from the EDID router's memory (static EDID
emulation), or from the last attached monitors memory (dynamic EDID emulation). For
example, the router can be set up to emulate a device, which is connected to the output.
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. EDID Router can be controlled via USB or serial port.
Info: The user is not required to disconnect the video cables 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.
Info: When EDID has been changed, the unit toggles the HOTPLUG signal for 2 seconds.
Some sources do not observe this signal, so in this case the change is not recognized by
the source. In such cases the source device must be restarted or powered OFF and ON
again.
2.7. HDCP management
Lightware Visual Engineering is a legal HDCP adopter, and has developed several
functions that helps to solve HDCP related problems.
2.7.1. HDPC key caching
Lightware introduced the HDCP key cashing technique in early 2009 that validates all the
display keys in an AV system during system boot up and keeps them constantly available
for sources. This method eliminates the HDCP handshake at every switch and keeps all
sources sending uninterrupted signals.
Without this function the sources should re-authenticate HDCP after each crosspoint
switch which makes the displays to drop the signal and go black for 5-8 seconds. The
HDCP key cashing technique avoids this and allows instantaneous switching between
two encrypted signals.
2.7.2. Avoiding unnecessary HDCP encryption
Many video sources send HDCP protected signal if they detect that the sink is HDCP
capable –even if the content is not copyrighted. This can cause trouble if a HDCP
capable device (e.g. repeater or matrix router) is connected between the source and the
display. In this case the content can’t be viewed on non-HDCP capable displays and
interfaces like event controllers.
Rental and staging technicians often complain about Apple laptops, who always send
HDCP encrypted signals if the receiver device (display, matrix router, etc.) reports HDCP
compliancy. However HDCP encryption is not required all the time (e.g. computer
desktop image) MacBook and MacBookPro still do that.

Page 14 / 107 Section 2. General description
To avoid unnecessary HDCP encryption, Lightware introduced the HDCP
enabling/disabling function: the HDCP capability can be disabled on each input port
separately. If HDCP is disabled on an input port, the connected source will detect that the
sink is not HDCP capable, and turn off authentication. The source will not be able to
communicate with any of the devices (displays, repeaters, etc.) that are connected to the
routers output, therefore it could not see if they are HDCP capable or not.
Note 1: If a source detects that the input port is HDCP disabled, it will send only unprotected
content.
Note 2: If a source detects that the input port is HDCP enabled, it could send protected or
unprotected contents as well.
Note 3: HDCP protected content will not be sent to any input port with disabled HDCP setting.
Note 4: HDCP protected content will never be sent to a non HDCP compliant display.
Please note that if HDCP capability is disabled on an input port, the connected source
cannot send protected content to any display. If HDCP function is enabled on an input
port and the source sends encrypted signal, the non-HDCP compliant devices cannot
display the video. This new feature does not remove the encryption of an encrypted
signal, and does not void HDCP standard at all.

2.8. Pixel Accurate Reclocking
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, or event controllers. Without reclocking,
sparkles, noise and jaggies can be seen on the image.
Lightware’s sophisticated Pixel Accurate Reclocking technology fixes more problems than
general TMDS reclocking. It removes not only intra-pair skew but inter-pair skew as well.
The Pixel Accurate Reclocking circuit eliminates the following errors:
Intra-pair skew: skew between the + and - wires within a differential wire pair (e.g.
Data2- and Data2+). It’s caused by different wire lengths or slightly
different wire construction (impedance mismatch) in HDMI cable. It
results in jitter.
Inter-pair skew: skew between two differential wire pairs in a cable. It’s caused by
different wire pair lengths or different number of twists in the HDMI
cable. Too much inter-pair skew results in color shift in the picture or
sync loss.
Jitter: signal instability in the time domain. The time difference between two
signal transitions should be a fix value, but noise and other effects
cause variations.
Noise: electromagnetic interference between other electronic devices such as
mobile phones, motors, etc. and the HDMI cable are coupled onto the
signal. Too much noise results in increased jitter.
The Pixel Accurate Reclocking circuit completely regenerates the original video signal
and outputs a strong, high-quality digital signal that conforms to the HDMI specification.
