Chapter 3: Installation
• You can cascade to more than two "layers" of VGA Video Splitters; that is, you
can begin plugging tertiary Splitters into the MONITOR ports of secondary
Splitters when you run out of MONITOR ports on the primary splitter. However,
the more VGA splitters that come between your computer and your monitors,
the more signal degradation you will get. Try not to go to a third layer of
splitters unless you absolutely have to—if you have to send VGA output to more
than a hundred monitors, for example.
