filmscanners: monitor shadows lines

["Paul Graham" <peegee@btinternet.com>]

Hi all,

when I look at my monitor (Sony F520 21") with say Photoshop opened at full
screen, but no image, just a grey background, any vertical black line has
ghostly repeats of that line echoing away to the right side, they get less,
but perhaps have four or five diminishing echoes.

I've tried all the controls, but not diminished it at all.
It doesn't happen with horizontal lines, or off to the left side of
verticals, just the right.

any ideas?
or is just a faulty monitor?
