SUMMARY
I bought the monitor Philips 278E1A, and from time to time the shared desktop
is not shown properly: quite difficult to explain. Basically, the image is
shifted right (or left) and the part that is outside the frame is shown at the
opposite side. See the attachment. Please not that the image refers to a
different monitor: I changed to a different one, same issue.

It seems that changing the frequency from 60Hz to 50Hz (or vice versa) fix the
problem temporarily. The issue occurs randomly, with no intervention.
