I changed the background display to rotate between a number of different images instead of being fixed on the seagull. In about a month the seagull outline and icon images were gone.

At least some "stuck" pixels can be fixed, but it depends on the construction of the display and the nature of the failure.

I've got the same seagull image on my laptop and there is no sign of burn in whatsoever. I think the moral of the story is not to buy inexpensive displays.

Stuck pixels are a different phenomenon from screen burn-in. The former is caused by a manufacturing defect that permanently turns on one of the sub-pixels (red, green or blue). Screen burn-in is caused by phosphor deterioration in CRT and plasma screens, and something else in LCDs, the science of which is lost on my brain (liquid crystal rotation inelasticity)!
