[comp.sys.cbm] Commodore 2002 : Monitor motion sickness

dar@cblpf.ATT.COM (David A. Roth) (08/16/87)

I upgrade my C64 setup. I bought a C128, 1571 disk drive and a
Commodore 2002 monitor.

I have some problems with the monitor that is going to be hard to
convince the place I bought it from.
I mostly use the monitor in 80 col mode and have noticed that the
display at times is jumpy it makes no difference what software I am
looking at. So far I use Pocker Writer 2 and Big Blue Reader. 
This is kind of hard to explain but it
reminds me of looking out the rear view mirror on an old shakey car. I
have used the monitor in 40 col mode but have not experienced the
problem. It may have just not surfaced in 40 col mode since I don't
use it as much. 
Sometimes it is just fine and then the display looks like it is
shaking up and down. Just enough to cause motion sickness for me.

Anyone from Commodore out there got any suggests? All this stuff is
new and I don't want to bring it back to the place I got it from only
to show them that is looks fine. The tech over the phone suggested it
might not be the monitor but something wrong in the C128.

Thanks in advance.

Sounds like you have some kind of EMF somewhere near. A flourescent light or
electric motor can do that. Or there may be a problem with your cabling or
some such... remember what floating O-scope probes look like?!

Try re-arranging your equipment, keep the disk drive away from the monitor,
and if you have a fan or florescent light, if you must have them, at least
keep them away from the monitor and power them from another plug.
