Your computer screen or monitor may have wiggling images when it is too close to electronic interference, such as a power supply, cell phone, non-shielded speakers, a fan or electric motor.
Here's some tricks I would try...
1. Verify the monitor's power cord is plugged firmly into the wall outlet and the back of the monitor.
2. Verify the monitor cable is firmly connected to the computer and the monitor.
3. Verify that you have turned the monitor power switch on.
4. If the power light on the monitor is not on, test the wall outlet (plug in a light or something you know works).
5. If the power light on the monitor is not on, try a different power cord.
6. If the power light is on and yellow or orange or flashing, but nothing displays, or the display is incorrect, borrow a monitor from a friend. If that works, your monitor probably needs replaced.
7. Also, you could try your display on a friend's computer. If it doesn't work, your monitor probably needs replaced. If it works properly on your friends computer, the problem may be with your computers video output port, motherboard video chip (or video card, if you have one), or drivers.
Good luck.

well it's not the computer going to sleep but the monitor is (sort of) because your computer is telling to. it has to do with the Power Options (title dependent on OS - this is what it's called in Vista)
Go to Control Panel>>Power Options - on the left hand column click Choose when to turn off the display - I'm guessing you are set to 15 or 20 minutes for the Turn off the display dropdown - change it to something longer to satisfy your needs (Never is an option).
If you're not running Vista write back - it's slightly different but similar path.
Cheers.

I took the advise of someone who wrote in and checked my refresh rate. I found it was at 60 and was advised to change it to 75. So far I haven't experienced any fluttering or wiggling so am hoping this will do the trick. I also checked all the plug in's that were connected to my power strip to make sure they were o.k. I still have one year left on my warranty so may have my monitor checked out just in case I've missed something. Thanks for your offer. I'll be sure to save your website for future questions.

try unplugging and replugging the monitor cable back in, and the connection to the computer, often this fixes the problem

It sounds like there is a cold socket on the internal power input of your monitor. Have a repair technician take a look at it. It should be relativley cheap fix if that is the case.
