6. Passive 3D Display
7.1 System Configuration:
7.2 AF5D Setup for Stereoscopic 3D Display
7.2.1 AF5D should not be set at the side of the projector where the ventilation hot air comes out.
7.2.2 Two projectors can be installed at side by side or Top/Bottom position. Closer lens position will
reduce [4 corner] adjustment range and reduce the loss of the image resolution and brightness.
7.2.3 Setup the polarized film and glasses so that RH/LH eye can only see the scene for one eye.
7.2.4 Use [4 Corner] or [Warp] adjustment Menu to align the images from two projectors completely
together. Place the polarized film in front of the projector before geometry adjustment
Activate [Image Properties] Menu by Front
Panel keypad or Remote Controller.
5 items in the menu.
AF5D-20 can decode 3D format from different
3D video sources, including Blue Ray DVD,
STB, Media player, Game and PC… 3D signal
will be decoded by AF5D-20 into signal for Right
or Left eyes. One AF5D-20 can only provide
signal for one projector. RH/LH 3D signals need
be displayed through two projectors. Each
projector will display signal only for one eye.
User needs to set a polarized filter in front of the
projector and also wears polarized glasses. The
glasses need to match the polarized filter in front
of the projectors so that the right eye can only
see the scene for right eye and the left eye can
only see the scene for left eye. A 3D screen is
also required to preserve the polarization of the
image for 3D display. It is possible to use optic
spectrum method similar to Dolby 3D display
using normal 2D screen.

7.3 Procedures for 3D Display Setting in AF5D
If still can’t verify “R” & “L” characters in both eyes, please check below again:
1. Is the screen for 3D display?
2. Are the Glasses and polarizers the same types and paired for the RH & LH eyes?
3. AF5D for RH eye should connect to RH eye projector and LH AF5D should connect to LH eye projector.
Please check from [Output Format] menu and make sure to have correct settings. If the connection is
incorrect, please use [Output Frame] setting to change the connection for RH/LH eyes. Don’t change the
connection cables. Otherwise geometry settings should be re-aligned again.
4. Is the Blue Ray player set to [Auto 3D] or [1080p @24Hz] mode to deliver 3D signal out?
5. If Side by Side or Top-Bottom 3D formats are used, please check the aspect ratio in video source output
to make sure AF5D will receive full screen image.
6. Is there any DVI/HDMI or signal source compatibility issue and only one projector shows image?
7. Are the DVI/HDMI cables qualified and the length not too long?
7. Warp and Geometry Correction of the Image
Each function in OSD menu may not co-exist. [4 Corner] adjustment can replace [Keystone] function. Inside
[Warp] menu, there is [Shift] function for 4 corner position adjustment. When [Warp] Menu is activated, [4
Corner] function will be disabled. While curved display is required, please activate [Warp] menu to adjust 4
corner positions by [Shift] menu and image curve by [Corner], [Edge] or [Center] Menu.
1. After image alignment, to activate [3D Properties]

2. Select [Automatic] if the 3D signal is standard 3D
formats from Blue Ray player or sources with 3D
index inside the signal.
3. Select [Side By Side] or [Top-Bottom] based on
user’s 3D input source.
1. Activate [Identify] menu to show “R &
L” characters on the screen
simultaneously to verify the final 3D
settings in the system.
2. RH eye should see only “R” and LH
eye should see only “L”.
1. To set [Output Format] and set RH eye AF5D
with [Right Eye Frame] and LH eye AF5D with
[Left Eye Frame] output format.
2. If the input is 1080p 24Hz and the projectors can
also support this signal, please select [Enable] in
[1080p 24Hz Output] menu in both RH/LH AF5D
to get the best 3D performance

8.1 [Keystone] Correction
If the projection direction from projector is not perpendicular to the screen, the image on the screen will have
keystone as below. In order to compensate, Keystone Correction is required. [4 Corner] adjustment can also
correct this kind of image distortion.
8.2 Image [Rotation]
Image Rotation is to compensate the misalignment between projector and screen. User can activate [Rotation]
under [Anyplace].
Image Rotation direction can be clockwise or anti-clockwise. The rotation angle is limited to ±30 degrees
under 1400x1050 output resolution and ±7 in full HD.
8.3 [4 Corner] Adjustment
Activate [Anyplace] Menu for Warp and Geometry
correction of the image.
[Warp] & [4 Corner] short cuts are available in
remote controller.
When Rotation menu is activated, Pin-Barrel
function will remain functional and all the other
functions in [Anyplace] will be disabled.

[4 Corner] can adjust each corner position of the image independently and is the simplest way for the
alignment in multiple projector applications, such as Edge Blending, stacking & 3D display.
1. Use OSD MENU to activate [4 Corner] adjustment or Press [4 CORN] hot key in Remote Controller
2. Maximum adjustment range for each corner is ±256 pixels horizontally (max. 300 pixels in Left + Right)
and ±200 pixels vertically (Top + Bottom).
3. Example for [4 Corner] adjustment:
Activate [4 Corner] menu then select the corner for the adjustment Press [OK] activate [PATTERN]
key to show Grid pattern and start [4 Corner] geometry adjustment. After finishing the first corner
adjustment, press [OK] select next corner press [OK] then Grid pattern will appear again
automatically and then start further adjustment.
Before [4 Corner] adjustment After [4 Corner] adjustment
8.4 Image [Edge Blend]
8.4.1 Projector with higher contrast ratio is recommended. It will reduce the light leakage in overlap region.
This light leakage will be more obvious in dark environment. it can’t be fixed by external signal control.
8.4.2 Use the same projector model and settings.
8.4.3 To align the grid patterns between two images all together with the same size.
8.4.4 To set video wall function through PC display card, AF5D-21 or other video wall controller.
8.4.5 Select the correct edge for image Blending, e.g. LH edge for RH image and RH edge for LH image.
8.4.6 Set [Edge Blend] value based on the overlap pixels (each overlap grid represents 50 pixels).
8.4.7 After above procedures, user can see the result of the edge blending. If the performance is not good
enough, then below procedures can be tried.
--Select different [Gamma] values and check video performance.
--Set right [Offset] value to compensate black level difference between Transition area and
--Non-transition area.
--Eliminate the banding effect via [Shift] blending position.
--Fine tune color from projectors or AF5D if necessary.
[Edge Blend] is to eliminate the banding effect in
overlap area between two images. Enough
pixels in overlap region (about 10%~20%) are
required to get good result. Before [Edge Blend]
setting, the image should be split and cropped
the right range. Geometry adjustment is also
required. Please see more detailed in
Application note in VNS website.

8.5.4 [Shift] adjustment (4 Corner adjustment)
8.5.5 Order
8.6 [Edge Mask]
Edge mask is a function to adjustment the display range of the image. It can mask each image edge up to 250
pixels with black background. The major purpose is to fit the image into the screen especially in the edge
blending application. In edge blending, if user applies geometry adjustment function, it will change the Grid
pattern size and aspect ratio in the whole image and affect the edge blending result. Edge mask is one
function to adjust the positions of the edges but still maintains the aspect ratio and location of the Grid pattern
without change. It will simplify the system installation.
The axis center can be adjusted horizontally and
vertically with the range of ±256 pixels in
horizontal position and ±200 pixels in vertical
position if the output resolution is under
1400x1050. In full HD output resolution, the
adjusting range is H±200 & V±150 pixels.
[Shift] function is to adjust the corners of the
image before or after Curved adjustment. It can
co-exist with other functions under [Warp] Menu.
The menu under [Shift] is the same as [4
Corner] adjustment to allow the adjustment of
the position in each edge independently in
curve image.
The response time in corner position
adjustment under [Shift] will be slower than [4
Corner] for flat screen display.
[Order] function is to decide the order for both
[Shift] and [Curve] adjustments.
For the correction of image distortion from
source side, user can select [Curved First].
For normal curved screen projection, [Shift
First] is defaulted and user can start with 4
corner adjustment.

10 Two projector image stacking procedures
1.1 Image stacking is a cost effective solution to increase the brightness of the projection system. User can
use two low cost projector with 4,000 lumen to stack up to 8,000 lumens easily at much lower cost.
1.2 One projector should be connected through [DVI Loop Back] port with native raw signal without
processing by AF5D and the other projector should be connected to AF5D output port.
1.3 To do geometry adjustment in the first projector to let the image match the screen borders through
keystone correction or lens shift function inside the projector, then to use [4 Corner] adjustment to align
the images from the 2nd projector onto the first one. External Grid pattern shall be applied from video
source.
1.4 For curved screen stacking, each projector shall be connected with one AF5D and user needs to align
the images through [Warp] function in AF5D unless the first projector can support curved screen
display.
1.5 If the screen is not flat enough, the image sharpness will be reduced in misaligned regions.
[Profile] is to save and load AF5D settings
including input port, output resolution and all
the settings in AF5D.
Five indexes can be chosen to save AF5D
settings in each AF5D and can be recalled
by IR remote controller or RS232
RS232 interface is designed with DB-9
connector. The UART Protocol between
AF5D and a Host computer can be
provided.
Detailed RS-232 protocol can be
provided as needed.
