CHAPTER 4: Operation
The ServSwitch Jr. will support SVGA (Super VGA) video, but with original Serv
cables the video quality for SVGA and Mac video will decrease markedly at higher
resolutions and distances. Table 4-1 illustrates this. The distances in the table are
total cable lengths measured from the CPU to the monitor.
Table 4-1. Video Quality vs. Distance for Original Serv Cables
Resolution
Distance
5' (1.5 m) 10' (3 m) 15' (4.6 m) 20' (6.1 m)
25' (7.6 m)
640 x 480 333 3 3
800 x 600 noninterlaced 333 2 2
1024 x 768 interlaced 332 2 2

Quality 3 = Near perfect; screen defects are not conspicuous
Quality 2 = Good to very good; images are clear; there are small reflections around
text lettering depending on the color; screen defects are sometimes
conspicuous
Quality 1 = Fair to poor as distance increases; images run from slightly fuzzy to
badly smeared; text runs from fuzzy but readable to completely
washed out
