I finally got a sweet Panasonic 1760 production monitor for my workbench so I designed and printed a cable holder in ABS which mounts on the side. It will also work with the 1710 monitor (and probably others) and you can download and print your own via my Thingiverse page
I also have these for sale at Shapeways
if you don't have a printer. See below for pictures.
This has worked so well that I printed one at Shapeways
in their strong and flexible nylon material. I have them up for sale so check it out.
