HDMI Connection Issues
•
3D requires a substantial data throughput therefore use a good quality High
Speed HDMI cable – with or without Ethernet.
•
Avoid using excessively long HDMI cables as this contributes to poor
connection issues.
◦
Cable lengths over 10 m are not recommended.
◦
Avoid using HDMI cables that have illuminated plugs or active systems
that draw on the 5 V supply rail. If the 5 V drops lower than 4.7 V you will
not get any picture!
•
Sparkles of random color on screen. This usually means that the cable doesn’t
have the bandwidth capabilities to handle the signal.
◦
Try changing the cable or use a shorter cable.
◦
Try using a lower resolution for example if you are using 1080p try
switching to 1080i. If this solves the problem the cable is the likely culprit.
•
When switching inputs on either the projector or the AV Receiver/Processor
sometimes the picture is either green or pink. This usually means the
incorrect color standard has been selected. This is sent automatically every
time you switch HDMI inputs but sometimes the information is not received
by the display.
◦
Reselect input, if problem persists disconnect the HDMI cable to either
the display or output of the receiver and reconnect – this instigate a hot-
plug detect and should resolve the issue.
◦
If the problem persists check with your AV receiver/processor/Blu-ray
manufacturer for the latest software updates.
◦
Try a different HDMI cable.
•
Snowy picture. This means that the HDCP system has not authorized the
playback of the material.
◦
Usually re-selecting the input will resolve the problem.
◦
If the problem persists then it is more than likely to be cable related. Try
other cables.
◦
Try bypassing other product in the system chain. For example connect the
Blu-ray player direct to the projector.
