I really like this swivel monitor/TV mount, it allows me to place the screen where I need it and out of the way when I dont. The arm extends across my desk so I can have it right in front of me sitting on the desk or move it back and have it raised up, whatever position you want, this can almost certainly do it.
Now I say this is almost perfect because when raised up, it just takes a slight bump or finger touch to make it drop a little. Yes you can tighten the tensioner screw, which I did and it still drops, so it's a little bit of a let down in that aspect. But I would still buy this again in a heartbeat
