There is nothing wrong ... the 'line' you see is a tension wire in the Sony
Triniton tube to keep the aperture grill from flopping around (and your image
converged) as it heats up.  ALL Trinitrons have it (the larger ones have
a pair) - it's just easier to see on the Mac2 since the screen is mostly
white.  Apple specifically had the tube installed UPSIDE DOWN so the wire
would be nearer the bottom of the screen (outside the 'peak' viewing area)
so it would be as invisible as possible.  Once you see the wire(s), you
will forever see them in EVERY Trinitron you happen to look at (they tend
to jump out at you once you know they are there ...).

*** THERE IS NOTHING WRONG WITH EITHER YOUR MONITOR OR VIDEO CARD ***
