I’m trying to get my dual monitors to work but the problem is
the dislplay properties don’t show the second monitor.
Like This.
Any ideas?
Anyone?
do you have your video card drivers up to date with the most recent version.
Sure do buddy.
Plus all the latest XP updates, program patches, service packs and so forth.
All sorted now 
Turns out, it was a faulty monitor so it wasn’t being detected.
Hooked up a different monitor,booted up the machine and hey presto,
two displays!
