I'm looking for something like an ergotron LX wall mount arm. I have 6 24 inch dell ultra sharp monitors. Problem is that I cant get a good aligned setup on my outside monitors. They are either two far away or i'm left with a good viewing angle but gaps between the bezels. The ergotron lx arm seems like it would do the trick because I need the full range of motion, but the arms need to be about half that size to make it work. Any suggestions on an alternative? 3x2 setup and must wall mount as I have a glass desk and cannot desk mount.
