Monitor's image shaking like jello..Why?

[Gyurza]

I got a 21 Inch Trinitron wich right before my moving was working properly.
After the Moving and set up my computer, i can not have a stable image..it is shaking like Jello..I use 1280x1040 with @ 75HZ before.. and now i have to keep it @ 60HZ wich makes it more stable but the glare is killing me..Any solutions please Help.
Is it my Monitor?

Thank you.

I ussually slap things that dont work. Except my wife and children of course. Try it, soft at first, then progressively harder till it fixes the problem. Even if it doesnt fix it, it does allow you to show your power an inanimate object quite nicely. My computer always runs quieter after i slap it. lol

Couple of thoughts:

You aren't by chance putting your cell phnoe, beeper, PDA, or other device on top of or under the monitor, causing interference?

Might try degaussing, it's in the menu on the front monitor buttons somewhere. Magnetic fields are sometimes altered when you move a monitor. Ususally causes discolorations, don't know if it will cause instablilty, also.

I would investigate what else was on that circuit. I had a window A/C unit that would mess mine up.

Placing monitors againsts certain walls with large amounts of wiring in them will cause the same effect. I had that happen when I moved my pc out of the living room into another room. The monitor started acting crazy. Someone suggested moving away from the wall and see what happens... I did and the problem was solved. Something in the wall was causing the monitor to flip out.... shake, etc.
