Why does my HDLink Pro 3D output show lots of green color with 3D Stereoscopic video?
If you are working with 3D Stereoscopic video, and your left and right eye cameras are out of sync, you will
often see half of your video image replaced with green color. This green image will appear on both the
monitor attached to the DisplayPort output of your HDLink and also to the 3D Muxed Video on the loop-
through SDI output.
The first three images, on the left of this page, show how this problem will present itself depending upon
which 3D stereoscopic output format has been chosen in the HDLink Utility. The last image shows the
correct image with no unexpected green color.
This problem is easily overcome by attaching a sync generator, to both cameras, such as the Mini Converter
Sync Generator or OpenGear Sync Generator from Blackmagic Design. The sync generator should support
high definition tri-sync signals.
Why does my HDLink Pro 3D output show lots of green color with traditional non-3D video?
Unless you are working with 3D Stereoscopic video, make sure that the setting “3D Stereoscopic”
is disabled.
If “3D Stereoscopic” is accidentally enabled, you will often see half of your video image replaced with
green color when working with traditional non-3D video. This green image will appear on both the monitor
attached to the DisplayPort output of your HDLink and also to the 3D Muxed Video on the loop-through
SDI output.
The first three images on the left of this page show how this problem will present itself depending upon
which 3D stereoscopic output format has been chosen. The last image shows the correct image with no
unexpected green color.
This problem is easily overcome as follows. Open the HDLink Utility, click on the 3D tab and disable the
option named “3D Stereoscopic”.
3D Stereoscopic Side by Side enabled
3D Stereoscopic Line by Line enabled
3D Stereoscopic Top and Bottom enabled
