Planar SD2420W User Manual

6 | SD2420W 

The SD2420W unit requires a dual-output graphics card to drive the two 
monitors with a DVI signal.  For professional applications that use OpenGL 
quad-buffered stereo, the graphics card should support OpenGL stereo as 
well.  Typically, the two monitors should be in clone mode for these 
applications.   

There are several compatible graphics card families.  The 

NVIDIA Quadro FX 

line and the Matrox Parhelia line have all been tested and are compatible 
for OpenGL stereo applications. The 

NVIDIA GeForce line offers dual-DVI 

output graphics cards that work well for PC gaming and DirectX applications.

configuration, and using side monitors with the SD2420W unit. 

 

Proper ESD (electrostatic discharge) handling precautions should 
be exercised when installing the mirror-flip PCI card.  Consult the 
computer manual for proper installation of graphics cards. 

Because the viewer will see a reflection of 
the top monitor, this image needs to be 
flipped on the horizontal axis.  A mirror-
flip PCI card is included with the SD2420W 
unit.  Plug this card into a free PCI slot in 
your computer.  There are no drivers to 
load with the card. 

1.  Remove the blank bracket from  

an available PCI slot. 

2.  Insert the mirror-flip PCI card into  

the slot, align the connector pins,  
and press the board down until it is 
firmly seated. 

 

3.  Secure the mounting bracket.
