12. Stereoscopic multichannel setup
12.1 AS3D modes
About
The F50 supports four different 3D modes : frame sequential, side-by-side, dual-head 3D and embedded 3D formats defined for
HDMI only.
When the source has 3D signal information embedded in the signal the projector will automatically switch to 3D and pr ocess the
signal correctly. T his will happen regardless o f the 3D m enu setting. When the signal doesn’t include 3D information, the us er
manually chooses the 3D mode in the menu that m atches the se tup.
In frame sequential 3D every other frame is interpreted as the left eye frame and the other input frame is interpreted as the right
eye frame. To ensure that the projector ch ooses the c orrect frames as the left eye and right eye frames, a 3D sync signal s hould
be c onnected from the IG’s display adapter DIN connector to one of the pr ojector ’s sync connector.
If such a signal isn’t pr esent (or
the 3D input sync is set to source), the projector will choose the first input frame as the left eye frame and the next input frame as
the right eye frame. This will be wr ong half the times the s ignal is a cquired.
In side-by-side 3D each input frame is divided in half and the left half of the frame is used as the left eye frame and the right half of
the input frame is used as the right eye frame. This makes the output width become half of the input width. If, for example, the input
is 1920x1200 @ 60 Hz, the output will be 960 x 1200 @ 120 Hz . As eac h input frame contains both left- and right-eye information
there is no need to synchronize the signal input in this mode.
In dual head, side-by-side 3D the projector will c hoose what is defined as the dua l-head 3D source 1 as left eye signal and dual-
head 3D so urce 2 as right eye. N ote that not all source com binations are poss ible. The projector will use source 1 to synchronize
the input. If the two input sources are not synchronous image artifacts will occur. The projector is only cap able of dis playing up to
120 Hz output, therefore it does not make sense to have individual sources faster than 60 Hz in this mode.
For so u rce s with embedded HDMI 3D signals the projector will a utomatically switch to 3D and process the signal correctly. The
projector will do so regardless of the 3D mode menu s etting. T his option is not visible in the 3 D mode menu.
