Yes! As a matter of fact I had my monitor exchanged because I couldn't stand 
the distortion (the screen displayed rectangles as pillows). The monitors of
my collegues, who bought their NeXTs at the same time, are STARTING to show
simular symptoms, that is, these monitors were quit good at first but now seem
to "burn-in". I don't know what NeXT has done to the monitors but those that
came with the cubes didn't show this effect (at leas not here in Basel).

As to adjusting: the service technition (and I) tried everything he could
(there are a number of controls "under the hood" at the back of the monitor)
but to no vain. It is easy to adjust the position and size of the active area
but quit impossible to adjust deformations (you would have to tamper with the
alignment magnets on the tube, which I strictly recommend NOT to do!).
