Planar SD2420W User Manual

8 | SD2420W 

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. 

Although the SD2420W 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

.  

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.
