Outlook and Functions
Minimum Equipment required for 3D display
Installation process for 3D display
1. Install projectors & screen to let projection images a little over the screen. Make sure to avoid heat
ventilation interference in the setup.
2. Connect all the cables. GeoBox RH output connects to RH projector and LH output to LH projector.
3. Reset GeoBox to factory default settings via [Option] menu to eliminate no unexpected settings.
4. Set polarizer into RH & LH projectors before geometry alignment. Make sure the RH/LH polarizers are set
in correct projector, direction and angle with distance of 5-15cm to the lens to avoid thermal damage.
5. Blue Ray player shall be set at AUTO 3D (or 1080p@24Hz) for 1080p frame packing 3D display.
6. For 2D to 3D conversion display, disable @24/30Hz output in Blue Ray player.
7. Turn on all devices. Some projector will search input source several times due to input timing change and
HDCP validation. GeoBox will automatically connect to input source. Then the screen will show up with
double images. To set HDMI as projector input may reduce the time for input searching. If no input source
is detected, GeoBox will go into power saving mode. The screen will show [Power Saving Mode] message
and GeoBox front panel LED will turn to yellow.
8. Select correct input source and set output resolution same as projector native resolution.
9. Make sure two projectors are in good focus and have the same settings.
10. Use [OSD Time] hot key in remote controller to set OSD Time Out to [Off] to show OSD & grid pattern all
the time during image alignment and 3D settings period.
11. Align two projector images together via [4 Corner] adjustment.
12. Use [3D Properties] to get correct input format and 3D settings for the best performance.
13. Test the final result and 3D performance.
1. 1x GeoBox
2. 2x Projectors (Native resolution above XGA
with HDMI input connector)
3. 2x polarizers (For RH & LH eyes)
4. 1x 3D screen (silver matte)
5. 3D glasses (Paired with polarizer)
6. 3x HDMI cables
7. Video source with 3D content

Two projector Image alignment procedures using remote controller
1. Power on the system after installation, double
images should appear on the screen. This is to
check if complete system is connected correctly.
2. Disconnect input signal during geometry
adjustment is recommended for easy Menu view.
3. If no signal is applied to the system, blue
background image is displayed.
1. Press [Pattern] key to show Grid pattern in CH-
A.
Continuously press [Pattern] key will change the
grid color.
2. Press [CH A/B] key to switch to the 2
nd
channel,
then press [Pattern] key again to show grid
pattern in the 2
nd
channel.
3. Left example shows CH-A in Red and CH-B in
Green color.
1. Activate [4 Corner] key to show [4 Corner] OSD
menu in one channel and another channel still
retains grid pattern.
2.
Select the corner to be adjusted by OSD direction
keys.
3. While full HD output from GeoBox, grid pattern
will show up with 50 x 50 pixels in each grid for
accurate alignment.
4. Each grid pattern size will be 50 x 100 pixels if
GeoBox is in 3D display mode in full HD output.
1. After press [OK] key, a Green Mark will be
showed at the corner to be adjusted.
2. The figure shows CH-B [Top Left]
corner is under
adjusting.
3. Use OSD direction keys to move the position of
the corner into screen border.
1. When finish the adjustment in Top Left corner in
CH-B, don’t press [OK] key.
2. Press [CH A/B] key to switch to CH-A.
3. [4 Corner] OSD menu for CH-A will be showed,
then press [OK] key, a RED Mark will be showed
at the corner to be adjusted.
4. If grid pattern disappears, press [Pattern] & [CH
A/B] keys to activate grid patterns in both
channels.

The above [4 Corner] alignment process can be applied to both 3D alignment and Image
Stacking in flat screen display. If curved screen 3D display is required, user needs to use
[Warp] function in OSD menu to align the images from two projectors together. [Warp] function
includes [Shift] (4 Corner adjustment), [Corner] curve, [Edge] curve and [Center] curve
adjustments.
Use OSD direction keys to adjust CH-A [Top Left]
corner to match CH-B, then press [OK] to go to next
step.
1. After press [OK], it will show [4 Corner] menu
again in CH-A.
2. Select the second corner to be adjusted.
3.
Press [OK] key, then it will show Red Mark at the
selected corner.
4. To adjust the position of the corner to match the
screen border by direction keys.
5. Press [CH A/B] to switch to CH-B and do the
same corner adjustment process.
After all corner positions have been aligned together
with the screen. The grid patterns from CH-A & CH-
B
will overlap together and show only one grid pattern.
1. Press [Exit] in remote control to turn off grid
pattern in one channel.
2. Switch to 2
nd
channel by [CH A/B] key, then press
[Exit] again to exist from the 2
nd
channel.
3.
User will get clear image after this process, if not,
please fine-tune the alignment. Then user can
start [3D Properties] setting.

Procedures for 3D display setting in GeoBox
To use [Swap] key to swap output connection if the connection is not correct. Don’t
change cable connection between GeoBox and projectors, otherwise all the
geometry adjustment shall be re-worked again.
After the above procedures, apply 3D signal source and wear 3D glasses, then user
can enjoy the most comfortable and healthy 3D system. It is the best solution for
children with minimum harm to the eyes.
1. After [4 Corner] adjustment, use hot keys in
remote controller to select 3D formats.
2. Select [3D/Auto] if the 3D signal is standard HDMI
1.4 3D formats from Blue Ray player.
3. Select other items based on user’s 3D input
formats: [2D to 3D] conversion, side by side [SBS]
or top-bottom [T-B] formats.
1. If [2D to 3D] format is selected for 2D to 3D
display, 3 setting items can be adjusted based on
personal preference: [Convergence], [3D Depth]
& [3D Offset]
2. Hot key shortcuts are available in the remote
controller for [2D to 3D] settings.
1. Press [L/R ID] hot key in remote controller to show
“R & L” characters on the screen simultaneously to
verify the final 3D settings in the system.
2. After wear 3D glasses, RH eye should see only
“R” and LH eye should see only “L”.
If it is not the result, press [R/L Swap] key in remote
controller to swap RH/LH signal. If it still can’t show
correct 3D, then review all the connections and
settings are required.
