I use two monitors, with the smallest (19") placed over the largest (27"). See photos. This ONKRON G75 was the only monitor arm mount/stand I could find with the height I required. Otherwise I am impressed with the build and material quality, and very thorough instructions. Everything about it has been well thought through. Stands to reason since it's an American designed product (and USA based company), and not Chinese. I can highly recommend this product.
