OK, this sounds like it's had some magnetic interference (as suggested
above). If the monitor is a decent one it will have a 'degauss' button
which will correct and misplaced gas inside the tube. Other than that, get
a magnetic screwdriver and starting from one corner of the screen make
circular movements around the screen, making smaller circles as you go
towards the centre of the screen, then pull the screwdriver away from the
screen quickly. This sometimes works.
Also, ensure that the screen is well away from and magnetic fields (such as
speakers). The magnets in speakers will pull the electrons around the
screen and create the phenomena descried.
The only other thing that I can think of is that the monitor has been run
at the wrong settings (resolution or refresh rate) and the screen has been
damaged. The only way to asses this is to put the monitor on another
computer (well away from magnetic sources) and see if the problem is still
there.
Cheers,
Bob.
