with the 3D option installed. When the 3D submenu appears, select 3D1, 3D2, or turn
the 3D off.
NOTE THAT FOR 3D, YOU WILL WANT TO INCREASE YOUR REFRESH RATE TO 85
or 100Hz. Do this prior to activating the 3D.
Using the 3D Function
The i-glasses SVGA 3D supports two 3D modes. In both modes, full resolution frame
sequential images are required.
Mode 1: DDC line protocol-The DDC line protocol is used principally by the nVidia stereo
drivers. If nVidia stereo drivers are active and outputting a 3D signal, the unit will
automatically detect the DDC line and stay locked to this signal. Note that this is the
highest priority 3D function. If this signal is present, the unit will automatically make the
corrections to maintain a stereo image. Thus, it does not matter whether you select 3D1 or
3D2 for this application.
Mode 2: Frame sequential stereo-the user can select 3D1 or 3D2 to activate the frame
swapping function. If the images are reverse stereo, switch between 3D1 and 3D2.
The i-glasses SVGA will also support line interlace 3D if the line blanking is done by IOD’s
Cruiser or MMGamer dongles or other similar hardware. Contact IOD to get more detail
on how to do this.
Note that if the HMD is 3D mode, the user cannot change the refresh rate or resolution of
the HMD-this function is temporarily disabled. If you wish to change these settings, exit
the 3D mode, then change the settings.
Troubleshooting and FAQs:
Q: I don’t get an image on the screen. What can I do?
A: Confirm that the resolution and refresh rate on your computer are set to 800 x 600 @
60Hz. If you are connecting to a laptop, make sure that the VGA out port is enabled.
Usually this is done with “FN-F5 or SHIFT-FN-F5” simultaneously. If you boot the laptop
with the HMD attached to the VGA out port, then the laptop should detect the presence of
the HMD.
If you still do not have an image, contact IOD.
Q: The image rolls, is jumpy, or has static on the screen. What can I do?
