My 17 inch CRT sometimes gets ...

light-colored horizontal lines
a couple of inches above the bottom of the screen
usually just one or two of these
the picture size too *sometimes* seems to get a tiny bit smaller
when these lines are present.

I have tracked this down to the signal lead going from PC to monitor.

This d*mn lead seems quite sensitive because slight kinks and bends
in the lead can create this effect. So can gently moving the plug as
it goes into the video card. Why can't they design a better lead
than this? It is already the most inflexible lead on my whole
system!

MY QUESTION IS ... is this lead usually as sensitive as this or is it
related to the design of my particular monitor and PC interface.

Can I do anything to improve the situation? I have lowered the
screen refresh rate a bit but that doesn't seem to have help.

Is there a "magic bullet" like something to clip onto the leqad or
some screening.

Changing the lead means some tricky messing around inside the monitor
to terminate the leads it in the screened cage sitting on the cathode
parts of the CRT itself.

Any ideas?

[Please don't say buy a secondhand 17inch monitor for next to nothing
because cleaning it and dusting out its internals to sharpen up the
image and all that stuff takes time, and so does fetching a checking
over monitors which turn out to be crap.]
