Sorry if this is in the wrong place. I have my computer in the left hand corner of the computer room/office and would like to mount a spare 19" widescreen monitor on the left wall. When fitted I would like the monitor to be pushed back against the wall out of the way. When I need it I would like to pull it away and position it next to the existing monitor. I know that there are plenty of these wall mounts about. I do however wish to use the second monitor in portrait when reviewing docs. I have found a few that rotate, but they are rather expensive. Any leads on a good brand. Ideally I would like to keep the price below £60 but will extend to £80 if I have to.
