AC/Mains powered phone? The transformer will radiate 50Hz, and it's quite
likely that your monitor is running a different frame rate (60+Hz). The
difference between them shows up as a beat freq, wobbling the picture
gently. My printer causes this in one corner of the picture when switched
on.

A regular phone-line powered shouldn't cause rippling, maybe some
bending of colours due to speaker magents ...
