"Sparkles" in image with GeForce Ti4200

I have a PC with a GeForce Ti4200 that I use with a KVM DVI/USB switch to
share an LCD monitor, USB keyboard and mouse that I use with another PC with
an ATI X800 XT Platinum.

With my PC with the GeForce (call it my "work" PC) I get "sparkles" in
graphic images. Essentially they almost look like LCD spots that are always
on (white). However, when I switch to my PC with my ATI card (call it my
"game" PC) everything looks fine when viewing the same image. The ATI
control panel has an option for "Alternate DVI mode" and "Reduce frequency
for DVI" which has eliminated any corruption that might have existed (next
to none).

I have tried swapping cables between the two PC's and to the monitor, and
tried all new cables altogether with no success. Same thing happens with
another KVM switch for DVI and PS/2 devices. So I feel it has to do with the
GeForce video card.

Has anyone had any issues like this and/or how to fix it?

If I can't eliminate it I may have to go with an ATI card since it seems to
work fine on my other PC. I hate to spend the money however, and my Ti4200
works just fine otherwise.

Thanks for any assistance!

Where are you getting the sparklies? 3D stuff or what? If you're
looking at a web page with a picture on it does it look weird? Texture
seem sparklies in 3D games, especially newer games, are sometimes just a
fact of an older card not having the hardware to render everything
without errors. Sometimes it's caused by heat. If you're seeing
artifacts in regular video or imaging software, the 4200 may be in trouble.

No, actually, just in Windows. My wallpaper exhibits it. Funny thing is, if
I switch to 16bit instead of 32bit or a lower resolution, it disappears. On
my other PC with the ATI, I realized I do get it there too, but just select
the "reduce DVI frequency" and all is well. I guess I could just run in
16bit, but I hate it. It causes banded colors on everything since everything
is now done in 32 bit color. My thought is that the KVM is at its limit. It
is rated for maximum 1600x1200 which is what I run at. Problem is I cannot
find another DVI / USB KVM on the planet besides this one and the Belkin
one. And the Belkin was even worse! Damn thing was so finicky, half the time
my screen wouldn't even display.

sigh

If anyone knows of another quality DVI / USB KVM, I would appreciate any
links where I can buy one.

Thanks!

My monitor has two DVI inputs and 1 VGA, no need for a KVM switch. Sell
your monitor to someone who doesn't need to plug multiple PCs into it
and buy one like mine, happens to be a Sony. Then just use the KVM
switch for the K and M.
I'm constantly hooking up various different computers to this monitor, I
had no idea when I bought it how useful the extra two inputs would be.
Wasn't even a selling point, turned out to be a necessity.
You just hit a little input button on the front of the monitor to cycle
between the three inputs.

This monitor supports one DVI, VGA, S-Video, and Composite input which can
be cycled by a button in the front. Unfortunately I've been spoiled by DVI,
otherwise I could connect one PC to the VGA input, but I hate to say it,
there is a significant difference in image quality, especially on an LCD.
DVI is so crisp and clear. VGA looks so blurry when compared to it. It would
be nice to have dual DVI inputs and an S-video becauase I hook my XBOX up to
this as well via S-video. So it is the perfect monitor for me (almost,
except I'd prefer dual DVI

By the way, what is the model of your Sony? All the Sony's I've found have
only a single DVI input with one or two D-sub (VGA) inputs.

What happens when you plug them directly into the monitor, bypassing the
KVM switch, does it go away? I understand your preference for DVI but
if it was me I'd just plug the 4200 into the VGA input on the monitor.
I'd think that even with the slight loss of signal going VGA would cause
it would be preferable to that.
Oh and it looks like I just have a DVI adapter plugged into a VGA slot
on the back, just one DVI input two VGA, I was just looking at the two
empty cables sitting on the floor, forgot how I'd connected them.

Well, I'm just returning this KVM and reverting back to my trusty DVI/PS2
KVM. Picture looks great and works great. I found another keyboard that I
like that is PS/2 and my Logitech Mx518 works fine with a PS/2 adapter.
