Well, I finally stumbled across what seems to have fixed it. After trying
to fiddle with every adjustment on the monitor's front panel menu buttons, I
finally looked at the last menu choice, which included color temperature and
something called "color return". Just out of curiosity, having tried
adjusting brightness, contrast, and about every other choice available, I
tried "color return", not having the faintest idea what that is. Well, the
screen went dark for a few seconds while I thought "oh s**t, what have I
done now?". Then it popped back on, and the faint little diagonal lines
were gone (at least for now). Not sure what that might have changed, but it
seems to be fixed. Hopes this helps another poor soul with the same
problem.
