Mu metal would solve that - but does cost serious $$ per pound (It acts
as a magnetic field blocker.)  You could try sheet steel, first, see if
it improves things;  Don't block the air ventillation, of course.  (A
vertical "wall" between monitors should improve things, I'd hope.)  I'd
bet the flicker's from magnetic coupling between monitors.

Graham:  Those connectors are "DB-15HD" connectors aka High Density
15-pin D-style connectors in the "B" shell;  Look in Mouser or DigiKey,
among others, I'm in the midst of ordering some and am pretty sure that
they're both carrying those in both solder pot and PCB mount versions,
if you bug me I can definitely give you parts numbers and etc., all
that's in the other room right now though.

I'm pretty sure the usual 15-pin to 15-pin cables are straight through,
not so for the NEC etc. 9-pin to 15-pin cables (there are at least 3
differing variants of those!).  The Hardware Book has pinouts,
