EDID management: Modular 4×4 and 8×8

EDID (Extended Display Identification Data) is information provided by a display to describe its capabilities to a source. It contains information including resolution, audio formats and frame rates. Modular has the ability to ‘Fix’ the EDID profile to allow a source to always pass video with a fixed resolution and/or specific audio output (i.e 1080p 60Hz, with 5.1 multi-channel audio)

If the system is functioning as normal, then no EDID management is required, however if you have a source that will not output the correct resolution/audio type, this can be resolved by following the instructions below

Please remove the SD card from the unit and connect it to a PC (Please do not use a MAC). On the route of the SD card is a file called ‘settings.ini’, this is the file that will be edited. Open the file in a text editor such as notepad, then scroll down to the bottom of the file

Enter one or more the following lines where required

edidprofile1 = x     ; sets the EDID profile for source connected to input 1
edidprofile2 = x     ; sets the EDID profile for source connected to input 2
edidprofile3 = x     ; sets the EDID profile for source connected to input3
edidprofile4 = x     ; sets the EDID profile for source connected to input4
edidprofile5 = x     ; sets the EDID profile for source connected to input 5  (8×8 only)
edidprofile6 = x     ; sets the EDID profile for source connected to input6 (8×8 only)
edidprofile7 = x     ; sets the EDID profile for source connected to input 7 (8×8 only)
edidprofile8 = x     ; sets the EDID profile for source connected to input 8 (8×8 only)

where x equals:
0 – Presents the source with the 1080p template EDID
1 – Fixes the EDID
2 – presents the source with the 4K template EDID
3 – presents the source with the 1080p template EDID with 5.1 enabled
101  – presents source with the EDID of the Sink connected to Output 1
..

108  – presents the source with the EDID of the Sink connected to Output 8

 

Once all editing has been done, save the settings.ini file, and reinsert the SD card back into the Modular unit.

Also please reboot any source where the EDID profile has been modified to allow the new EDID data to be passed.

Modular and IR Control

Modular units have the ability to receive Infra-red(IR) commands in two different ways; Code-based IR and Contextual based IR. Code-based IR uses unique codes for each room/output, whilst Contextual IR uses a single set of codes, with the unit determining where the IR command originated.

If you wish to revert the unit to Code based IR control please edit the settings.ini file on the SD card (Please use only PC based systems to edit the SD card contents) and remove the following information.

cir1 = 0x00ff9867
cir2 = 0x00ffd827
cir3 = 0x00ff8877
cir4 = 0x00ffa857

cir1 = 0x00ff807f
cir2 = 0x00ff00ff
cir3 = 0x00ff30cf
cir4 = 0x00ff906f

Using a multi-channel 5.1 / 7.1 amplifier receiver AVR with a matrix

Using multichannel 5.1 / 7.1 amps AVR with matrix systems

Essential Knowledge
To understand how multichannel (5.1 / 7.1 etc) audio/sound is routed via a HDMI or HDBaseT matrix system, it is important to firstly acknowledge that all HDMI source devices (Blu-ray players, set-top-boxes, media servers, PCs etc) can only output a single audio format type at any one time. This is a limitation of HDMI itself.

For example, the HDMI port on a Blu-Ray player cannot simultaneously output HDMI with 2.0ch stereo as well as HDMI with 7.1 DTS Master audio. It is always one or the other.

arctical

With only displays connected to the matrix
When a matrix has only displays connected, with no AMPS/AVR in your set up, routing audio is relatively easy. This is because displays generally only have two speakers, and so a single HDMI format of HDMI+2.0ch can be routed to all displays. This gives you video and audio at every display.

Adding an AVR/AMP the matrix
When adding an AMP/AVR to the connected device mix, you are adding a component that can accept a multichannel audio format, such as 5.1 or 7.1.

You now have a situation whereby some connected devices (displays) can only accept HDMI with 2.0ch stereo and some (the AVR/Amp) can accept HDMI with multichannel audio.

What to expect in a mixed display / AVR setup
Video matrixes operate on a “lowest common denominator” rule. This means that the matrix will exchange information with your displays and AVRs to decide on the format of audio to get from the source device; choosing the format that will ensure audio is output in all of your locations.

One of two things can happen: If the AVR is turned on first and the matrix set to send a source capable of multi-channel audio to the AVR, the source will deliver multi-channel audio to the AVR. If a stereo TV is then turned on and the matrix then set to send the same source going to the AVR to the TV, the TV will be unable to play back the multi-channel audio. The result would be no sound from the TV.

In the reverse, if a TV is turned on first and the matrix is set to send one of the connected sources, the source will deliver stereo audio to the TV via the matrix. If the AVR is then switched on and the matrix set to deliver the same source going to the TV, the AVR will only receive stereo audio.

It is important to re-iterate, this is not a product limitation of HDanywhere matrixes. This is a limitation of HDMI technology itself and its specification.

A solution is therefore required whereby the source device always sends multichannel audio to the AMP/AVR and 2.0ch stereo audio to the displays.

Solution options
There are many ways to solve this problem. Some complicated, some easier. Things will depend on the location of your equipment and the number of AVRs. We are always happy to help you build a specific solution that meets your setup. Here we can only cover some of the more common setup examples and a single solution to those.

I have a single AVR located beside / local to my source devices and the matrix e.g. in a cupboard / AV rack.
In this type of setup, where the AVR for the multi-channel room is located with the sources and matrix itself, one solution is to deliver the audio to your AVR via alternative connectors to the HDMI where possible. For example, Sky HD boxes and Blu-Ray players usually have a digital audio output that can be connected to the AVR** via optical cabling. This can deliver multi-channel audio to the AVR over the optical cable, whilst the HDMI output from the source device can deliver 2.0 ch stereo audio to your matrix and therefore your other TV (stereo) locations in your setup. If this setup is located away from the room with multi-channel speakers fitted, say an under-stairs cupboard, there are solutions to keep IR control of your AVR that we can help with.

AVRs located in the room with the displays
In this type of setup, where AVR(s) are located in the rooms local to the displays, make sure the HDMI device is set to output 5.1 / 7.1 channel audio. This audio format will be sent over the Cat cable to each display location. In order to get audio out of your HDTVs (in say three rooms) and the AVR (connected to HDTV in a fourth room), some additional hardware is needed. HDanywhere sell a signal manager. Place 1 x signal manager at each TV that needs 2.0 channel audio aka. each TV that does not have an AVR.  Use a HDMI cable to connect the HDMI output port of the matrix’s display receiver to the HDMI input port of the Signal manager. Then use another HDMI cable to connect the HDMI output port of the Signal Manager to the HDMI port on the HDTV. So, the Signal Manager sits in between the display receiver and the HDTV.

The Signal Manager has a box labelled “Audio”. The little switch on this audio section needs toggled to number 2: LPCM 2.0 before you connect up and turn on all your HDMI source devices and displays. Do not switch toggle the switch from no. 1 to no. 2 whilst displays and HDMI sourced devices are on. If you do so, you will need to power down the re-power all source devices and displays.

Once the signal manager is set up and in place it will take 5.1 and output it as 2.0, ready to be accepted and then output by the HDTV. This should hopefully resolve your issue and deliver 5.1 to your AVR and 2.0 to your HDTV.

**When using alternative audio connectors other than HDMI, support for DTS-HD Master Audio and Dolby True HD is lost.

Troubleshooting: Green screen

Important:
In most cases, if you are experiencing green screen on your display then this is often down to the HDMI cable in between. A quick way to test to see if this is the case is to replace your existing HDMI cable with our range of 4K or 8K HDMI cables. If that doesn’t work, move your HDMI source to another display in your property (use a different HDMI cable), connect it up and observe to see if the same behaviour follows the box. This will help you determine if the issue is the cable or the HDMI source.

The article below describes how to troubleshoot a green screen when using a HDANYWHERE product, if you are having green screen issues and you do not own a HDA product then we recommend you buy our 4K or 8K HDMI cables and give that a go first – they come with free shipping!

Symptom:

There is no picture or maybe a green screen following standby or when switching between source devices via a matrix. Most often this problem occurs once the TV goes to standby, and when brought out of standby to an ‘on’ state, it will not handshake properly and green screen instead of video appears.

Green screen flashes generally indicate a HDCP (Digital Content Protection) handshaking issue, or a HDMI hot plug detect issue between that particular source device and display.

HDBaseT Wiring Guidance

HDanywhere video distribution systems require a single network cable to be run from each HDTV location, back to a central point. Some single wire systems use HDBaseT technology to transmit over 1 x Cat5e/6/7 cable up to a 100 / 328 ft metre distance.

This article is designed to give you a good overview of the standard of wiring needed for a HDBaseT system. For a detailed, official set of guidelines issued by HDBaseT click here.

Troubleshooting: “No picture on one of the TVs connected to my matrix”

In order to effectively troubleshoot this problem, we need to deduce whether or not the matrix, the HDMI cables, extender set, or other connectivity accessories such as wallplates, repeaters or cable joiners are at fault.

Troubleshooting Step 1

Swap the outputs over on the matrix to see whether the problem follows the cable run, or stays associated with the HDMI port. This will help us decide whether it is the cable run or the matrix at fault.

Outcome 1: Problem follows the cable.

You have isolated the issue to be associated with that particular cable run and TV. If possible, try an alternative HDMI cable (such as the one connected to another TV on the matrix) to deduce whether a known to be working cable solves the issue. If it does, there is a good chance that the original HDMI cable is at fault and requires replacing.

Outcome 2: Problem stays with the port on the matrix.

You have isolated the issue to be associated with that particular HDMI port on the matrix. This issue could be hardware or software related.

Firstly, to rule out whether it is a software issue, follow the hard reset procedure (described in manual) to reset the matrix software. If this does not revive the troublesome HDMI port, it is likely that there is a hardware fault with the matrix.

In this case, Contact Customer Services. for a replacement unit.
