3D content is displayed as two near-identical images
• If they are next to each other, press the 3D key on the remote control and
then choose Side by Side 3D Input Format.
• If they are one above the other, press the 3D key on the remote control and
then choose Top and Bottom 3D Input Format.
3D image lacks depth
• Press the 3D key on the remote control, highlight the 3D Left/Right setting and
then choose the value (either Normal or Swapped) that restores the correct
sense of depth in the image.
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 connec-
tion 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 switch-
ing 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 incor-
rect 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 play-
back 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.
