14) Blu-ray: 3D
– is the equipment used 3D enabled/
compatible? Is a 3D disc being played in a 3D enabled
Blu-ray player or through a compatible AV receiver?
15) 4K
- Are you trying to pass a 4K signal? Ensure
connected devices are 4K enabled, correctly configured
and outputting compatible transmissions.
4K resolution -
ensure all connected devices are
compatible with the UHD or DCI resolutions being
transmitted. See Specification section for more details
1080p
- 1920x1080p, 60Hz (if problems are experienced
at 60Hz, try lowering to 50Hz)
Combined 4K / HD distributions - a WyreStorm EXP-SCL-
DAC-4K scaler may be required between receiver and
display to scale down 4K transmissions to 1080p 24fps
for HD screens and upscale 1080p to 4K 30Hz for UHD
displays
16) 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.
No Sound or Poor Quality Audio
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.
1) Have specific speaker sets or zones been
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.
It may be an EDID issue in that the source reads the audio
EDID from the display and only requests two channel
audio.
The EXP-EX-HDBT-50 features automatic internal
handling of EDID between devices so in EDID disparity
cases, inclusion of a compatible device enabling manual
EDID management to copy EDID from the AVR may
be required. Contact WyreStorm Tech Support for
assistance.
Note:
If problems are experienced 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 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 correctly
set to the maximum capabilities of the devices:
4K
- Supported screen resolutions - consult the
Specification section of this manual for details on
supported UHD and HD resolutions.
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 emitters at the IR TX transmitter end
and receivers at the IR RX receiver end –
are they
connected to the correct ports on each unit.
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 the sensor within the fascia of the source
display. If necessary, secure the emitter over the sensor
with a small amount of contact adhesive.
