Does the Ergotron DS-100 quad-monitor stand need to be bolted down? Or does it stand on its own? I can't seem to find an answer to that question, and I assume that means it needs to be secured. Are there any quad stands (square arrangement) that stand on their own?
I think this one is better and cheaper: http://www.atdec.com.au/Content_Com...Solutions_VISIDEC-Focus-Freestanding-Quad.seo
