easier than component or coax cable. Furthermore,
lead quality varies dramatically, particularly in lower price
brackets. Swap your HDMI leads and check operation –
damage to or quality of your leads could be the problem.
If in doubt, swap them over. Always take care inserting
and extracting your HDMI from matrix ports so as not to
damage the connectors or ports.
13) Picture snow/HD ‘noise’ – represents a poorly
established signal that may be caused by poor quality
terminations or excessive cable lengths. Try swapping the
display adaptors from a location you know is functioning
properly or swapping the outputs of the matrix switch
used.
If the problem remains on the same screen this may be
caused by a connection problem between matrix and
display – turn off all equipment and swap the signal
carrying cables at both ends to ascertain if the cable or
termination is at fault.
14) Blu-ray: Deep Colour – make sure Deep Colour is
turned on in your Blu-ray settings and displays.
15) Blu-ray: Resolution – if a reduction of resolution to
720/1080i produces an image, cable issues such as
interference, patch panels, wall outlets, stranded cable
use or excessive cable length are likely restricting
transmission of a full 1080p signal.
16) Blu-ray: 3D – is the equipment used 3D enabled/
compatible? Is a 3D disc being played in a 3D enabled
Bluray player or through a compatible amplifier?
17) Colour distortion – a pink or green screen indicates
an incompatibility between colour spacing formats – the
commonly used RGB or YUV used by older displays.
Some sources allow switching between RGB and YUV
which may solve any colour problems. If not, try changing
the HDMI cable between the source and the matrix to rule
out defective cabling.
Audio is transmitted within the video signal – there
is no separate audio track – so generally a problem
with sound will be accompanied by a problem with
picture. However, if technical issues with audio are
experienced, the cause is typically communication
between sources, displays and/or AV receiver
settings.
No sound or poor quality audio
1) If using an AV receiver, check your source input
assignment – do you have specific speaker sets or zones
enabled? Some AV receivers allow individual speaker
selections assigned to specific zones in the set up so
check the speakers used are fully connected to the
amplifier and correctly assigned within the system set up.
Note: If you experience problems when an AV receiver is
used, the cause is usually the settings of the AVR itself.
Refer to the AVR manufacturer’s guidelines on the correct
settings to use for your requirements.
2) Consistency of audio output between devices – Is
there any discrepancy between the audio output of the
source, the audio or zonal settings of the AV receiver and
the speaker configuration used needed for successful
audio replication? If you are outputting 7.1, make sure all
devices connected are also outputting 7.1
Note: Occasionally with some sources, the device
settings allow the specification of audio output through
a TV or an HDMI port. If using an AV receiver, check the
HDMI output option is selected.
3) Do all the local sources work through the AV
receiver?
Check the operation of each source individually.
Bandwidth
1) If using a graphics-based source (such as a PC/Mac/
media server), make sure the source resolution is set to
a maximum of 1080p, 50Hz. Higher resolutions available
for graphics-based systems require higher bandwidth
that may affect transmission of signals as well as
incompatibility with devices.
IR
1) Check you are using emitters at the IR TX
transmitter end and receivers at the IR RX receiver
end – are they connected to the correct ports on the
matrix and display receiver.
2) Is the emitter correctly positioned on the source?
Fix the emitter directly over the infrared sensor of the
source and attach using the adhesive backing.
Note: Locate the infrared source sensor by using a
flashlight to find s small sensor within the facia of the
source display. If necessary, secure the emitter over the
sensor with a small amount of contact adhesive.
3) Is your remote powered and sending a signal?
Note: IR is invisible to the naked eye, so use a digital
camera/ phone camera to check the remote signal – point
the camera at the remote control when pressing a button.
You should see the remote transmitter flashing to indicate
