Windows 7: Wobbly screen

Hi,

am typing from a Windows 7 with a wobbly screen - as in 'trembly' monitor screen. The pc was renewed from an XP P4 to a Win 7 duoCore, new tower, monitor, the lot: the earlier setup also had a faintly wobbly screen. Is this then something to do with regional connectivity (West Country UK)? It's obviously not a pc problem. Perplexed

Thanks,

Ric

What do you mean by "wobbly"? Is the full on-screen image shaking, distorted, or is it partial?

And seeing as you new rig also has a new monitor, and the problem is persisting, you need to look at other sources of the problem.

1. Are there any cell towers in close proximity to you?
2. Any wireless communications technology, such as 2-way radios?
3. To you have any refrigerators or microwave ovens connected to the same circuit (i.e. the same breaker) as the one to which you PCs are connected?
4. Are there any industrial equipment, like electric welders and such nearby?
5. Is you power outlet delivering a clean stream of electricity?
6. Are you using a surge protector?

Thanks Dzomlija,

Good reply

This is an intermittant thing, the screen sort of 'trembles' slightly now and then, most noticeably at the edge of the screen and on lettering.

No, a surge protector is not used, is this a good idea?

Thanks again,

Ric

What is the 'refresh rate' set at?

AS you ask if it might be a connectivity problem (which I doubt but) does this only happen when you are connected to the internet. If you have a Modem/Router switch it off to try without a connection!
I'm nearly as far west as you can get without getting wet and have no connectivity problems at all. Where are you exactly?

59 Hertz

59? I thought they were typically 60.

near Blandford Forum

thanks - i used the term 'connectivity' in its broadest, loosest sense since i simply do not know what is causing the screen jitters :-o

says 59

But what about this?
