Section 3: Operation
3D Sync Output: This option defines whether the 3D Sync is output and controls how it is processed. It is only
valid when an optional cable is used to connect stereo 3D signals to the projector via the GPIO port. When
there is no 3D signal, Sync Output should be 'Off'. Typically only the last projector in the 3D Stereo cable
chain is connected to the emitter and should specify 'To Emitter'. All other projectors should select 'To Next
Input' if other projectors are used in the chain.
3D Stereo Sync Delay: Adjust the output 3D emitter delay (in milliseconds) to match the active glasses to the
L/R frames of the projector. Proper adjustment of this delay will eliminate cross talk and odd colors caused by
timing differences between the glasses and the projected image. Your specified delay is added after sync
locking.
3D Test Pattern: Enables a 3D test pattern for diagnostics. The scrolling diagonal lines indicate how well left
and right are synchronized. If ghosting is occurring the input may have to be switched or inverted. Adjustments
to the emitter delay can also help correct the synchronization. To verify that your 3D is setup correctly, a small
set of "L"s will be visible when you close your right eye and a small set of "R"s will be visible when you close
your left eye.
Frame Locking: Enable or disable Frame Lock. When set to Frame Lock, if possible
output image frames are locked to the input. When Locked, the output is always locked
to the primary input and never the secondary image, when using Dual input 3D. Free
Run sets the output to close to 60Hz for all sources. This control must be set to locked
if a 3D-Stereo signal is used.
Set Frame Delay: Delays the output signal timing relative to the input signal timing by a fraction of a frame,
and up to several frames. The minimum latency can vary based on the amount of scaling applied to the image.
When using keystone or warping, an additional latency is required, depending on the amount of warp. The
control is only available when the input signal is frame locked. In free run mode, or in cases where the signal
cannot be frame locked, the minimum latency defined by the scaling and keystone/warp is applied to the
signal.
Actual Frame Delay: Displays the actual frame delay reading.
Full Screen Eye-Motion Filter: Check this control to apply the Eye-Motion Filter to the entire screen, rather
than applying just to the edge blending regions. Helps with posterization effects, sometimes seen in color
ramps when viewing stereoscopic images.
Eye-Motion Filter: Adjust this filter to reduce saccadic eye-motion artifacts, sometimes noticeable in edge
blending regions. Too much filtering may result in loss of detail. For best results, adjust this setting while
positioned at the nominal screen-viewing distance.
Edit Secondary Channel Settings: When using Dual Input 3D, this allows you the option to independently
control primary and secondary channel settings, or to use the same setting for both links. By default, this
control is unchecked, meaning any settings applied to the primary input will also be applied to the secondary
input. In this case, the secondary channel settings cannot be set. When checked, the secondary channel settings
become editable.
Main Input: Select an input from the drop-down list.
Secondary Input: Select an input to be used as secondary input in a Dual Input 3D setup.
Display 3D Message Boxes: Enable/Disable message boxes that are triggered by 3D setup.
message box is shown in "Off" and "Valid" state.
