I have two Ergotron 33-296-195 LX Triple Display Lift Stands. Yes they are triple, but unless you use 21 inch and smaller screens you can only fit two. I used them side by side for a total of 4 curved screens. These are very nice and you can dial and adjust the weight of the springs so that no matter what monitors you use, they will carry the weight and you can adjust them easily. There are used but work great. 100 a piece, or 175 for both. Thanks!
