Connect the power cords
Two power cords shipped with the unit. Use only the power cords supplied
with the unit.
1. Plug the 10-foot cord into the AC power jack of the top monitor. Plug the
6-foot cord into the bottom monitor. Then plug the power connectors
into a grounded outlet.
2. Turn on the soft power switch located on the front bezel of the two
LCD monitors.
3. Power up the computer.
Check the alignment
Although the SD2220W unit is aligned during manufacturing, it may require
realignment after reassembly at your site. There are two fine adjustment
screws located on the mirror support arms. Rotating these screws raises or
lowers the beamsplitter mirror. Adjust the screws so that the corners of the
reflected image of the upper monitor are aligned with the corners of the
transmitted image from the lower monitor.
You may want to use a test image during the alignment process. A sample is
available at www.planar3d.com.
Perfect alignment between the two images is not required for stereo viewing.
The human visual system is typically adept at "fusing" two images that are
slightly shifted relative to each other. This is especially true for horizontal
alignment. In a careful manner, try to achieve vertical alignment as closely as
possible. Coarse vertical misalignment can cause eye fatigue or headaches
since the eyes are accustomed to seeing stereo images from the same vertical
position.
