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.

graph TD
    A["PC or Mac"] -->|Who are you?| B["Display"]
    C["PC or Mac"] -->|I am a monitor. Here is my EDID.| D["Display"]
    E["PC or Mac"] -->|Now I know what I can send.| F["Display"]

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 PC, then a Lightware DVI-TP-TX200, a WUXGA (1920x1200) LCD as local monitor, then a DVI-TP-RX100 connected to a SXGA (1280x1024) projector. I would like to see the same image on the monitor and the projector. What EDID should I chose on the DVI-TP-TX200?" (see typical application in section 2.8)

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.

Problem: „I turned the rotary switches on the DVI-TP-TX200/TX300 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 DVI-TP-TX200/TX300 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 the Universal EDID (address 49). It supports all common VESA resolutions. Additionally it also features audio support.

2.5. Advanced EDID Management (DVI-TP-TX200/TX300)

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-TX200/TX300 provides Lightware's Advanced EDID Management function that helps system integration. It stores and emulates 99 EDIDs 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-TX200/TX300 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-TX200/TX300's memory (static EDID emulation) or from the attached monitor (dynamic EDID emulation). For example, the DVI-TP-TX200/TX300 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. TMDS Reclocking (DVI-TP-RX100)

DVI-TP-RX100 reclocks the signal on its output using Lightware's sophisticated TMDS Reclocking technology. Signal reclocking is an essentially 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 to transmit the video signal.

The TMDS 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 DVI cable. It results in jitter.

+ - Intra-pair skew

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.

Diagram illustrating a twisted cable with polarity indicators and a jitter symbol, likely from an electronics or signal processing context.

Noise: electromagnetic interference between other electronic devices such as mobile phones, motors, etc. and the DVI cable are coupled onto the signal. Too much noise results in increased jitter.

Diagram illustrating a twisted cable with positive and negative terminals, alongside its corresponding noise waveform diagram.

Info

TMDS Recklocking technology does not eliminate more than on bit of Inter-pair skew.

2.7. Fiber Cable powering

As a special feature, DVI-TP-TX200/TX300 (MONITOR OUTPUT) and DVI-TP-RX100 (DVI OUTPUT) are able to supply 500 mA current to power fiber optical transmitters like Lightware DVI-OPT-TX100 (Pin 14 on DVI OUT connector). Standard DVI outputs or VGA cards supply only 55 mA current on +5V output, thus unable to directly power a fiber optical transmitter.

Info DVI-TP-TX200/TX300 and DVI-TP-RX100 do not check if the connected sink (monitor, projector or other equipment) supports Hotplug or EDID signals but output the input signal immediately after it has been applied to the input.

3. Operation of DVI-TP-TX200/TX300

3.1. Power

When building an electronic system, make sure that all of the devices are powered down before connecting them. Powered on devices may have dangerous voltage levels that can damage sensitive electronic circuits.

1. After the system is complete, connect the output of the +5V Power Adaptor to the DVI-TP-TX200/TX300 (further on TX200/TX300) The unit is immediately powered ON.
2. After being powered on, the TX200/TX300 displays its firmware version using the EDID Status LEDs.
   The following example shows this process for a firmware version of 1.3.7
   RED blinks once → Short pause → GREEN blinks three times → Short pause → GREEN blinks seven times → Short pause → The normal function of the LED is in effect.
3. After indicating the firmware version, the red EDID status LED lights up for 2-3 seconds, then turns green if the selected EDID is valid, or remains red, if the selected EDID is invalid (or the selected memory is empty).
   After the TX200/TX300 is initialized, the attached DVI source and monitor can be powered on.
4. If a display device is connected to MONITOR OUT, the TX200/TX300 reads the EDID from the attached monitor's EDID memory.
   If the read process is successful, the GREEN LED blinks several times then the EDID Status LEDs show whether the selected EDID is valid (green) or not (red) on the DVI INPUT connector.
   If the read process is unsuccessful, the RED LED blinks several times then the EDID Status LEDs show whether the selected EDID is valid (green) or not (red) on the DVI INPUT connector.

Info If none of the LEDs light up upon power-up, the unit is most likely damaged and further use is not advised. Please contact [e-mail]

3.2. Learning the EDID

The factory preset EDIDs cannot be changed by the user. Only addresses from 51 to 99 are user programmable.

1. After connecting the sink device to MONITOR OUT, use a screwdriver to select an empty memory address. EDIDs are stored in a multiple programmable non-volatile memory.

If the red EDID status LED is illuminated, then the memory slot is empty and ready to be programmed. If the green EDID status LED is illuminated, the memory was already used before, but still available for programming.

1. Push the LEARN button on the front side of the TX200/TX300 and hold it down for approximately 3 seconds.

Once the button is pushed the EDID status LEDs go dark. If the EDID storing was successful, the green EDID status LED blinks five times and stays illuminated. Now the stored EDID is automatically emulated.

If the storing was unsuccessful, the red EDID status LED blinks five times and either the red or green EDID status LED becomes illuminated, depending on the previous status of the selected EDID address.

3.3. Switching the EDID

1. Use a screwdriver to change the memory address on the front side of the TX200/TX300.

After either one of the rotary switches has been rotated, the unit waits approximately 2 seconds before the selected EDID becomes active. If the EDID status is unchanged the EDID status LEDs do not blink, but stay continuously lit.

1. The address 00 (zero zero) has a special function. If a monitor is connected to MONITOR OUT, then its EDID is copied to the DVI INPUT connector. If no monitor is connected to the output then the EDID transmitted to the DVI INPUT connector is the EDID of the last connected monitor.

Info If an invalid EDID is selected, the TX200/TX300 does NOT give a HOT PLUG signal to the source connected to DVI INPUT.

Info

After every EDID change, TX200/TX300 toggles the HOT PLUG signal for approx. 1 second. Some graphic cards or DVD players do not sense the HOT PLUG signal, and even if EDID has been changed, the set resolution is not affected. In this case the source device must be restarted, or powered OFF and ON again.

3.4. Factory preset EDID list

Lightware factory pre-loaded EDIDs are specially provided to force graphic cards to output only the exact pixel resolution and refresh rate.

Universal EDID (address 49) allows multiple resolutions including all common VESA defined resolutions. In addition, it also features audio support. The use of universal EDID is recommended for fast and easy system setup.

4. Operation of DVI-TP-RX100

4.1. Power

When building an electronic system, make sure that all of the devices are powered down before connecting them. Powered on devices may have dangerous voltage levels that can damage sensitive electronic circuits.

1. After the system is complete, connect the output of the +5V Power Adaptor to the DVI-TP-RX100 (further on RX100). The unit is immediately powered ON.
2. After being powered on, the RX100 displays its firmware version using the EQ mode status LEDs.

The following example shows this process for a firmware version of 1.3.7

RED blinks once → Short pause → GREEN blinks three times → Short pause → GREEN blinks seven times → Short pause → The normal function of the LED is in effect.

1. After indicating the firmware version, either the red or green EQ mode status LED stays continuously lit, depending on the last selected mode.

After the RX100 is initialized, the attached monitor can be powered on.

Info If none of the LEDs light up upon power-up, the unit is most likely damaged and further use is not advised. Please contact [e-mail]

4.2. Adjusting the input equalization

The amplitude of high frequency signals decreases after they pass through long distances in copper cables. To counter-act this phenomenon, RX100 amplifies the signal while maximizing the amplitude at a certain level, which is defined by the DVI 1.0 standard. This process is called equalization.

The RX100 offers two equalization modes: automatic and manual. Automatic mode usually provides perfect transmission but at longer distances and higher resolutions, manual equalization may be necessary.

1. Select the equalization mode by pressing and releasing the EQ mode selection button once. The two EQ mode status LEDs show which mode is currently active.
2. Use a 2-3 mm flat head screwdriver to manually adjust the equalization level. Turning the knob clockwise increases the EQ level, turning it counterclockwise decreases the EQ level. The knob of the potentiometer does not stop at the end positions, but rotates indefinitely. After reaching the end position, a clicking sound can be heard at every full turn of the knob.

IMPORTANT! When installing the RX100 in a system, always check which equalization mode is selected, because a previously set manual equalization level may not be suitable for a different system. It is always advised to use the automatic mode and only adjust the equalization manually if the auto mode does not give a good result.

4.3. Maximum twisted pair distances

The following table shows the maximum twisted pair distances. The actual achievable distances may differ, depending on the topology of the whole system. Unshielded Twisted Pair (UTP) cables are susceptible to EMI coming from surrounding devices (cables, mobile phones, motors, etc.). Noisy environments substantially decrease the usable length of unshielded cables. Hence the use of shielded Category 6 cables or Category 7 cables is always recommended. Category 7 cables are screened and foiled by standard.

5. Troubleshooting

5.1. There is no picture

Check the cables

Due to the high data rates, the cables must fit very well. DVI connectors have to be locked with screws, no tensions or breaches are allowed. If your source or display has more connectors then make sure that the proper interface is selected.

Check if the CATx cables are connected properly between the transmitter and receiver.

Check the source equipment

Check the Source Connected LED on the front side of the DVI-TP-TX200/TX300. This LED indicates the presence of the +5V signal coming from the DVI source. If it is not illuminated, then your DVI source is not working properly. Please refer to the user's manual of your DVI source.

If the source is a computer, then verify that the DVI output is selected and active. Try restarting your computer; if you get a picture during the booting process, you have to review the driver settings.

Check the incoming signal

Check the Signal Present LED on the front side of the DVI-TP-RX100. This LED indicates the presence of an active incoming DVI clock signal. If it is not illuminated, then no DVI clock signal is present at the VIDEO INPUT connector.

Make sure that the proper equalization mode is selected and if manual mode is active, the right amount of equalization is set.

Check if there's an outgoing signal on the Monitor Output connector of the DVI-TP-TX200/TX300 (also check the Monitor LED on the front panel). The input signal is always routed to the DVI and RJ45 output connector(s). If there is a signal on the

Monitor Output connector, then the problem is not EDID related. Check if the CATx cables are connected properly.

Check the display status

Check the Monitor Hotplug LED on the front side of the DVI-TP-RX100. This LED indicates the presence of the Hotplug signal coming from the attached display device. If it is not illuminated, then your display is not powered or not configured properly.

Check EDID related problems

Check the EDID Status LEDs on the front side of the DVI-TP-TX200/TX300. These LEDs indicate whether a valid EDID is selected. If the red LED is illuminated, then an invalid EDID or an empty memory address is selected. Please select a valid EDID.

If the green EDID Status LED is illuminated, then maybe your display device is not capable of receiving the sent video format. Try emulating your display device's EDID to the source. You will find help to this process in section 3.3. If you get a picture now, you have an EDID related issue, please read chapter 2.4 for more details.

Check the EDID

Maybe the data rate is too high for that type of cable. Try switching another EDID to the inputs with lower resolution. If the source is a computer and you are an expert user, you can try modifying the refresh rate, so you would be able to get it to work at higher resolutions over a noisy connection.
