My PowerBook 540c has a grid on the screen. It's as if there is a white border around every single pixel, so the overall effect is a "screen" or white grid. The PowerBook seems completely normal otherwise, and the whole display does seem to be visible with no other artifacts. Having no experience with early color LCDs, I kind of just assumed this was a normal feature of that vintage of LCD. I almost feel stupid for asking, but is this normal?

Peace,
