2.4. Understanding EDID
2.4.1. 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 2-2. 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.
2.4.2. Common problems related to EDID
Problem: „My system consists of the following: a computer, a Lightware UMX4x4-Pro
matrix, a WUXGA (1920x1200) LCD monitor, and an SXGA (1280x1024)
projector. I would like to see the same image on the monitors and the projector.
What EDID should I chose on the monitor and the projector?”
Solution: If you want to see the image on both displays, you need to select the resolution
of the smallest display (in this case SXGA), otherwise the smaller display may
not show the higher resolution image.
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.

User’s Manual
Section 2. General description Page 13 / 129
Problem: „I have a UMX4x4-Pro 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.
2.5. 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 (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. UMX4x4-Pro provides
Lightware’s Advanced EDID Management function that helps system integration. The built
in EDID Router stores and emulates 150 EDID data plus all monitor's EDID that are
connected to the output connectors. First 100 EDID are factory presets, while memories
100 to 150 are user programmable. The router stores the EDID of all attached monitors or
projectors for each output in a non-volatile memory. This way the EDID from a monitor is
available when the monitor is unplugged, or switched off.
Any EDID can be emulated on any input. 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 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. EDID Router can be controlled via serial port or Ethernet.
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.
Info When EDID has been changed, the router 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.

2.6. HDCP management
Lightware Visual Engineering is a legal HDCP adopter, and has developed several
functions that helps to solve HDCP related problems.
2.6.1. Mixing encrypted and unencrypted signals
Complex AV systems often have both HDCP and non-HDCP components. Lightware
hybrid modular routers allow to use HDCP encrypted and unencrypted signals in the same
system.
HDCP and non-HDCP I/O boards can be used in the same matrix frame. The router will be
still HDCP compliant as it will never output an encrypted signal to a non-HDCP compliant
display device. If an encrypted signal should be switched to a non-compliant output, it will
show a red screen alert or will be muted.
2.6.2. 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.
2.6.3. 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.
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.
2.7. 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.

Page 16 / 129 Section 2. General description
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.

3.3.2. DVI outputs
29 pole DVI-I connectors for outputs have only digital pins internally connected. This way,
users can plug in any DVI connector, but keep in mind that analog signals (such as VGA
or RGBHV) are NOT available on the outputs.
Fiber Cable powering
DVI outputs are able to supply 500 mA current on DDC +5V output (pin 14 on output
connectors) which is sufficient to supply power to fiber optical DVI cables. Standard DVI
outputs usually supply only 55 mA current on +5V output, thus unable to directly power a
fiber optical cable.
Info The matrix switcher does not check if the connected sink (monitor, projector or other
equipment) supports Hotplug or EDID signals but outputs the selected signal immediately
after switch command.
