I thought it was me at first - too much real ale - but no, my monitor image is wobbling slightly. Its just as if the picture was made of jelly, a sort of trembling motion. Its just started over the last couple of days, and whilst the monitor works fine otherwise, I'm curious as to the cause. The monitor is a middle-aged HP7500, 17inch, being pushed along by an HP534a running XP Home. Monitor drivers are up to date, and I haven't touched any settings. Most curious!

Any ideas?

Cheers,

George

Do you have a large power adapter near it.
I find if you have like a cellphone charger or something near some computer monitors then the screen will wobble a bit

Otherwise i agree with stevonz and the monitor is on its way out.

Perhaps drinking some ale will cancel the effect?

Explode?? Yikes!!

(*Claps on steel helmet and rushes out to buy more real ale!*)

Sounds like an excellent excuse to get me one of them nice flat-panel LCDs!

Thanks for the replies, and watch for the mushroom-cloud over inland Hawkes Bay!!

increasing screen refresh rate has helped me fix that a few times, 60hz refresh rate is same as AC mains supply so more EMI at that freq is present.

try unplugging other devices (especially cheap 9-12v power supplies aka "plugpacks" like cordless phone power supplies) these are a common cause of interference. I have a few of these that need to be kept well away from my monitor or I get the same thing

Hi Barf, tried bumping up the refresh rate, but no diffeence. I don't have any power adaptors close to the screen, so maybe its just getting old and tired, like me!! Thanks for the ideas, though.

(Sigh! *Reaches for steel helmet again*)

I would suggest it may be dieing, or at least the video cable part of it perhaps.

Perhaps try plugging it into another computer and see if it does the same with that?

On the upside, like you said, it is a good excuse to get yourself a new LCD. Now days you can get something pretty good for under $500
