@shogun:
Sticking a metal or aluminium bar to the desk is something i thought about myself too at first. And i came over a slightly problem with that solution. Let's say you arrenged 4 TFT's very well to 2 aluminium bars, but a half yeah later you are switching from 19" to 22", they won't fit anymore. You have to rearrange them on the desk, that would leave some ugly holes at the old place. Or what if you only want to change position on the side of the desk? It would be to unflexible without a movable arm attached to each monitor.

A workaround would be:
Stick the Ikea leg upside down on an extra 4-6mm thick woodplate (or better a metal plate) with nuts and bolds. The size of the plate must have a minimum size of 25x25cm. Put 4 small foot's unter the plate from a hi-fi system (you can buy them at every store where they selling hi-fi systems).
Same goes with the wood example, but before you use that one of that you've postet, get a normal 20x20mm woodbar from the store and attach it to a woodplate with bracket's.

This solution was my last option too, if the company would have rejected my order or if they would have been too expensive as well.

@Hec130:
I found that too, when i was looking for a solution, for 4 TFT's it was good, but not for 6. And after all it has the same problem as mentioned above. It is to unflexible in arrangement (on the desk) especially with 6 TFT's.


Well an other option is to combine both examples
What i mean is, using the 4 moveable arms (shown on Hec130 picture) on an extra metal bar, attached to a wood or metal plate.
