#Monitor ghosting
5 messages in this thread
For various reasons, the main one being the need for capable business software
running on a computer for which spare parts are still available, I finally had
to buy a 486 computer.
In order to use my 17 inch monitor with both machines (my Amiga is a 3000 with
the built in de-interlacer), I purchased a switch box and two db15 cables (6
feet long) to connect to both my computers.
I now have a ghost image on my screen. When I connect my Amiga or 486 directly
to the monitor the problem disappears.
Has anyone solved this problem or does anyone know how I can solve this problem
without having to plug the monitor directly into each computer every time I
switch between them?
Thanks for any help.

Try a new switchbox (a different brand would be best). You seem to be getting
some interference through the switchbox.

You're best bet is to get a better quality switch box — you're losing signal
somewhere in its innards.

The ghosting is being caused by an impedance mismatch somewhere along the
monitor cabling (most likely at the switchbox connections). This mismatch
causes a reflection of the signal and hence the ghost. A better switchbox may
help or at least reduce the intensity of the ghost.

Thanks for your (and Rick Green's) suggestion to replace my monitor switchbox
to clear up the ghosting. Although it turned out the switchbox was not at
fault, your messages did put me on the right track.
Since I purchased a decent quality switchbox in the first place, I thought I
would try and contact switchbox manufacturers to see what they had to say. I
eventually reached someone at Belkin Components who knew exactly what the
problem was and that she had helped a couple of other people with the same
problem. All I had to do was purchase a couple of special cables. When she said
they were expensive I figured 20 or 30 dollars a piece. They were $72.95
each!!! And on top of that she wouldn't guarantee results and since they were
custom made they were not returnable.
Since she sounded pretty confident the cables were the problem and I had no
other choice (and the ghosting was driving me crazy), I decided to give the
cables a try. They arrived yesterday. They were pretty beefy looking and
besides the model numbers, printed on the cables was "Space shuttle low voltage
computer cables." Well, if they didn't clear up the ghosting I would at least
have the coolest, most expensive cables in the neighborhood.
Fortunately, they worked perfectly. My picture is now crystal clear from both
computers. If anybody wants the Belkin lady's address and phone number please
feel free to email me.
Thanks again for your help.
