TROUBLESHOOTING
Should you encounter installation difficulties or issues with device communication, the following checklist of
common issues and causes should help resolve your issues If you still continue to experience issues, please
contact your local representative for further assistance
No or Poor Picture Quality
• Connected and powered? Double check all HDMI, Ethernet and power cables are firmly connected into the
correct ports and all devices are correctly powered
• Cable length? Are you approaching the maximum distance of the CAT cable (eg 100m) if so, try adjusting the
picture resolution/format, or try using an additional extender kit on the HDMI output to go further distance
Cables bundled together may cause cross-talk and further degrade signal quality
• Signal strength? The use of cable joins, stranded patch panels, wall outlands and stranded patch leads as
interconnects between them can significantly reduce signal strength. Use solid core straight through connections
wherever possible
• If you reduce the resolution of the source (eg from 4K to 1080p), do you get a picture? If so, this suggests a
conflicting resolution between source and display or a bandwidth capacity issue with your cable. Check all inputs
and outputs share the same resolution capabilities
• The neo:4Pro can support a maximum HDMI input TMDS clock of 340 MHz, which is equivalent to 102 Gbps Any
video format above this datarate, such as 4K@60Hz 4:4:4 or 4K@60 HDR, is not supported
• Picture ‘snow’ / HD ‘noise’ signifies a failure to fully establish a signal and can often be caused by poorly terminated
RJ45 connectors or excess cable lengths Ensure your cable is correctly wired to 568B standards
• Pink or off-colour picture? This could be caused by an invalid EDID or the source device failing to read the EDID
from the matrix Try re-booting matrix and all source devices to force the re-reading of the EDID
• Cable quality and condition - HDMI cable/connectors can easily be damaged and the quality of material can vary
Always use good quality leads and cables and try swapping cables that are known to be working into the solution
to see if this improves your image
No Sound on Speaker
Make sure that you are wiring the matrix to the amplifier correctly.
If connecting to a stereo amplifier, please ensure that you are using a suitable HDMI (digital) to analog converter
with downmix (eg P8-HDMIDAC)
EDID Handshake
There may be times you will need to perform an EDID Handshake on your Matrix This is often
after a new piece of equipment has been introduced to your setup or any changes have occurred
To do an EDID Handshake:
1 Turn off the Matrix and all Sources
2 Turn on all TVs, and make sure these are not set to standby
3 Wait 45 seconds
4 Power on Matrix and wait for x3 Green Lights on the front panel
5 Wait a further 45 seconds
6 Turn on all sources
