A:AnswerHi there, the depth of the wall mount while this one is completely closed is the following: 3.16" Please keep in mind Best Buy provides a 15 days time frame in which you will be able to exchange or return the product if you determine it will not fit your needs. - John Rocketfish Support
A:AnswerHello! The VESA configuration specifications for this mount are: 75x75, 100x100, 100x200, 200x100, 200x200. As a result, you should have no problem with a 100x100 VESA configuration with your monitor. Daniel T. - Rocketfish Support
A:AnswerI would not use this bracket for a tv that big. Unless I just have a defective bracket I have only a 32" tv and this bracket struggles to hold it straight. I straighten it and by the next day it has slipped tilting toward the floor again.
A:AnswerThis will angle as far as 90° left or right, as long as there is sufficient wall clearance. It could probably angle even farther if the tv is small enough and there is no wall blocking it.
A:AnswerYou will have to buy a larger mount, which "Rocketfish" makes. I have 40' tv which worked well, no problems. The instructions were very simple for mine, I believe the larger mount will be the same!!!
