Have 3 monitors side by side, now I need one over the top of the center monitor. How?

I traded in a room where monitors were mounted on a pole, with a heavy flat base. But forgot the name of the product. Any other ideas?

 

I just got a email from Judy at EMC Tech a fe days ago about this stand setup. Actually, I think they are running a special with 4 24" Samsung displays. They have a 1 over 3 stand configuration - http://www.shop.emcworkstations.com/4-Display-Monitor-Mount-1-over-3-413P.htm?productId=10

 

or this one - http://www.shop.emcworkstations.com/2-Display-Vertical-Monitor-Mount-230P.htm?productId=7. I think they have a higher pole also, for 3 monitors high.

 

ergotron? i use atdec visidec for the cooler looks. anyway, they both cost around $150-200. I don't know why you'd need a stand for horizontal

 

I use the box the monitor came in.

 

Thanks.
