PC hardware and software installation using Nvidia display card
1. Nvidia display card with [3D Vision] support is required for high performance
1080p @120Hz active 3D display.
2. Insert Nvidia IR emitter to the PC and make sure the green light on emitter is on.
If no IR emitter, Nvidia card will not send out 120 Hz 3D signal.
3. Connect with DualLink DVI cable between PC Nvidia card and GeoBox.
4. Update new Nvidia display card software driver if necessary.
5. Install Nvidia 3D Vision Video Player with version 1.7.5 or above. Stereoscopic Player] software also can be
used for the playback of video content.
6. Both “Nvidia 3D Vision Video Player” and “Stereoscopic Player” may not support some video format. In this
case, to install “Video Codec” is required.
7. GeoBox can decode any frame sequential active 3D signal from Nvidia or AMD HD3D display card. Even
mother board embedded display can also output frame sequential active 3D signal but only with lower
resolution or only 60Hz refresh rate.
PC settings
1. Nvidia 3D Vision IR emitter is required in GeForce 3D Vision display card.
2. EDID Override: User needs to do EDID override setting to let Nvidia card output the right 3D signal. This
EDID will determine the output resolution from Nvidia display card no matter which output resolution is set in
PC Display Panel. After update .INF file in display driver, user needs to re-boot PC.
3. User needs to set the right display timing (same as projector native resolution and @120Hz refresh rate),
aspect ratio and 3D setting in both Display Resolution setting menu and also in Nvidia Display Control Panel.
4. If not full screen is found, there are three possibilities:
a.
PC Nvidia card output doesn’t set to full screen.
b.
GeoBox aspect ratio is not set to full screen.
c.
The projector is not set to the right aspect ratio.
5. User can press [Info] shortcut key in GeoBox remote controller and check the input and output timing modes.
No matter what kind of output resolution is set in Nvidia card, user will see the [Input Mode] remain the same
as the EDID override setting (should be @100/120Hz) and the [Output Mode] is set by GeoBox (should be
@50/60Hz).
Other helpful tips in active 3D display
1. The major 3D format that GeoBox can support from active 3D is “Frame Sequential”. Once this 3D format is
detected, no matter it is 60Hz, 100Hz or 120Hz, GeoBox will decode it into R/L outputs. Through the passive
3D system, users will see stable 3D effect without flicker.
2. When playing 3D video from PC, the sequence of R/L image may be swapped. User can swap R/L outputs
from GeoBox by [R/L Swap] shortcut key on the remote controller.
3. Nvidia IR emitter may interfere with other IR remote control devices.
4. If user can’t see 3D effect, one of the reasons is that “3D view” in the Player is not activated (as showed
below). Click the icon to active 3D view.
