Shaking Picture

[webstar]

I have a S3 Savage 4 and a ATI All-in-Wonder on a Win2k system. The Monitor on the S3 card the picture starts shaking for no reason at random times but when it does it makes the monitor next to it shake. What can be making the picture shake???????

Is your s3 your primary adapter? If not set it to primary. Read about s3 and secondary adapter not working right. I think it was in list of fixes in sp2.

It's all setup right it has just started doing this lately.

Small fans or other electronics can effect a monitor in this way. If you are in a cubicle, look at your neighbors desk, they might have something that interferes with monitors.

Are you experiencing a color shift when the screen shakes or does it look like the picture is just vibrating? Is the monitor an older model?

[webstar]

Monitor is about 14 months old, No Colour shift just just looked like the picture is vibrating.

Is the shaking accompanied with a click from the monitor, it could be a degauss? Also, have you switched the monitors to different cards. You know, move the monitor that was on the S3 to the Ati and vice-versa. Also, there are a few things that can cause a shake like the one you are describing. The oddest I've ever seen is an elevator. When it passes this user's floor, her monitor degaussed, very wierd.

It could also be that one monitor is better "shielded" while the other remains sensitive to interference.

A nasty source of interference can be fluorescent lighting. I'v seen a user scrap 3 monitors before we found out that the source of the problem was flourescent (tube) lighting in a desklamp!

Thats right, check if your office has switched brand of flourescent lights. Had to redo a conference room because of bad lighting, projector shook like an earthquake and the TV/monitor kept changing channels and volume because of the infrared output of the lights.

If the S3 needs to be the default to work properly with a dual display setup Webstar has a problem. The ATI All-in-Wonder TV tuner won't work if it isn't the primary adapter. Also with a dual display setup make sure the two monitors are set to different refresh rates or they will have some interference problems between themselves. I have my primary set to 100Hz and the secondary at 85Hz.

how close are the monitors sitting next to each other?.. when I was runnin dual monitors they were too close and when I would bump my desk the image would shift, and shake....

A friend of mine has a similar situation. He has a TV next to his monitor, and whenever the TV is turned on, the monitor starts shaking. Turn the TV off, and the monitor is rock solid.

We think it's some sort of shielding problem. We tried putting a sheet of metal between the two, but it didn't seem to help.

The monitor is seperated from the TV by an isolation transformer which should block any RF through the power lines.

Does the monitor input cable have a cylinder shaped bulge on either end? These are magnets which are supposed to stop funky interference. I saw an ATI card that came with ones you could install if your monitor didn't have them.

Try putting the two on different circuits, or maybe changing the refresh rate.
