I was looking for a stronger monitor mount as my trusty D7L just didn't fit my 49" X800E. Having recently decided to upgrade to the LG CX 48 OLED, I decided that "It was time we finally got a monitor arm that wouldn't sag under the weight of a large display. Ergotron HX is in fact one of the few solutions when you need more than 40 pounds of lifting capacity. And that's how I took it. The design is solid as you'd expect from an Ergotron.Assembly is simple, instructions simple and clear.Note that you can adjust the spring tension on the arm section with a VESA plate as I've found it to be quite difficult after that to adjust them I also had to buy a VESA adapter for the CX 48 as the brackets that come with it only support mounting up to 200 x 200. In general i st the mount is very impressive. It's very smooth and smooth in motion, and it didn't show any sign of sag (after adjusting the spring tension). The only downside, and a big one, is the price. If you don't need that much cargo capacity, the next best option (and the one I'd recommend) is the Locktek D7L (up to £33) for over $100 less.
