A:AnswerYes, this will fit your TV. Your TV requires VESA compliant 100x100 standards. this mount fills in for VESA 75mm x 75mm, 100mm x 100mm and 200mm x 200mm.
A:AnswerIt appears heavy duty enough to work with a 40" . You will lose a small portion of the swivel motion because the arm will not extend far enough from the wall to produce a 90 degree movement. (It would need to extend only 1" further to get the full 90 degrees.)
A:AnswerAbsolutely. Vertical or horizontal configuration are instantly switchable. The mount is strong and secure. The TV easily rotates and tilts. The are some knobs that you can twist to adjust the amount of tension in the tilt or rotation. Tighten them just enough and the TV will stay in exactly whatever position you choose.
A:AnswerIt has various size bolts like m4, m6 in various lengths with spacers. Just put one up with no problems. You can go to the Sanus website and look at the instructions to see all the parts. Hope this helps.
A:AnswerThe wall mount now comes with the extenders, I used on my new 32" Samsung . If you don't have the extenders, maybe you can contact the manufacturer and get them.
A:AnswerJust a solid stud that will support the weight. Mounting hardware was included. Need drill, Phillips screwdriver, and wrenches ( socket, combination, or adjustable).
