I used this for my 28" Samsung UHD display, and it worked great.If your monitor is within this mount's acceptable range and the mount doesn't seem to be able to hold up the monitor's weight, try adjusting the upward tension.At the hinge between the two sections of the mount, there is a Allen screw with a +/- sign engraved around it. Tightening it towards the + (counterclockwise) will allow the mount to hold up a heavier monitor.The instructions do not seem to explicitly state this, and it is not terribly intuitive, which is a failure of the product, but not enough for me to dock a star.I debated springing for a more expensive mount (this was 35 dollars for me), but decided to take a risk, and it works perfectly for me.If your desk is tight against a wall, and you don't want your monitor 3/4 of the way across your desk up against your nose, you can adjust the arms so that the monitor is also up against the wall (arm swivels at the base, have both segments one on top of the other)
