A:AnswerYes it will however the motion up and down is limited somewhat so depending on how much you want it you may want to go to a Best Buy and see the display.
A:AnswerIf you have room to swing the TV out from the wall, you could probably install it pretty close. To remove TV from mount is simple; just one screw removal and it's free.
