Try this - join two cable together, bypassing the kvm. See if it still
looks bad. Some video cards don't have good output stages, and don't
withstand being extended. The same can go for the output stages on the
kvm. Use the shortest practical leads, where possible.
There's no way to do that. These are custom cables that have
single/special D-Sub connectors on one end that pick up the video and
vga signals, and breakout cables on the other end for plugging into the
connections on the computer. The strange thing is, this is a much more
expensive KVM than the one I replaced, which worked perfectly. I was
only trying a replacement because of a different issue I'm having with
some strange interference between my phone and my computer wiring. (When
I sit down at my desk, the device that picks up my handset and switches
to my headset, picks up the handset without being asked to, and at the
same time, the mouse and keyboard freeze on my computer - but, I digress)
Arrived at work this am and found three computers running, but none of
the LEDs on the KVM were lit, and I faced blank screens, and a
completely non responsive KVM. Reboots, keystrokes, and mouse movements
had no effect. Since this new KVM didn't solve the main problem I was
trying to fix anyway, I saw no reason to persist with what is obviously
a flaky or poorly designed product. My old IOGear KVM which cost half of
what I'd paid for the new one, is back in the mix, and works perfectly.
