Just got second machine. Stayed w/ one monitor (Trinitron). Bought an A-B switch to share monitor. Switch works but I get a blur - enough to be annoying. Any suggestions on trouble-shooting? Have moved switch well away from the PC. Cables seem a little cheap. -Thanks, Brian

Extension Cables and switchboxes are notorious for causing ghosting or streaking on the screen. This is almost always due to an impedance mismatch at the cable connection to the extension cable or switchbox.

This type of problem usually gets worse as you increase resolution or refresh rates.

Impedance miss matches will send small video ripples (for lack of a better term) up and down the video cable. These ripples are amplified by the monitor and show on the screen as very small ghost images or streaks particularly after a bright to dark, or dark to light transitions.

I would recommend you avoid switch boxes for video. Many monitors these days have dual video inputs specifically so you can connect two computers to one monitor. This is the best way to go.

Good Luck
