It is possible that the source of your problem is electromagnetic interference. This type of interference can cause your Dell M992 monitor to be wavy or "oscillate" in the manner you have described.
Please follow the steps below in order, moving from one to the next only if the previous step did not resolve the problem:
Environmental Checks
Eliminate all power strips and UPS boxes and connect the speakers and computer directly to the wall outlet. Remove magnets and large electronic devices at the very least three feet away from the computer and speakers. Fans, neon lights, fluorescent lights, power transformers, and power poles should also be away from the speakers and computer. If there are any large electrical appliances on the same circuit as the plug that the speakers and computer are connected to, then you may want to try a different outlet.
Relocation
Relocate the computer and monitor to another room or location for at least 24 hours to confirm if the environment causes the problem.
