Purchased the Ergotron Neoflex LCD arm from Fully. The arm holds two 2x Dell S2318H monitors attached to a Jarvis Sit-Stand Desk. In the corner of each monitor comes out around 15″. My desk is 26.5″ and so I find that my fist reaches the monitor snug. My only wish would be that I had a deeper desk to push the monitors back slightly.
