Question: What is the configuration of the screws? Are they side by side 1 set on top, the other bottom? Are they going down a straight line top to bottom?
Document: Make sure you hit a stud, line the included template and drill some pilot holes. I used a socket set to drive the screws in and we had the 42 inch lcd hanging in less than an hour (60 lbs)...most of that time spent locating studs behind the plaster wall and figuring out how high we wanted the tv.I had seen in some reviews there was an issue with the tilt.
At first I thought it was not going to work, I have 32 in TV Insignia. It is kind of on the heavier side. So I immediately thought that it wasn't going to work. It was fairly simple to install. 2 people needed for perfect results. Only problem I had was that the screws that I needed did not come in the package. So if you have your TV's original screw, you can use those with washers. Once every thing is up and tight, it is nice and solid.
Luckily I did not follow the instructions in order and put this on my wall right away. There are supposed to be 4 extension brackets, 2 each of 2 different types. I got 4 of the same so I sat for 1/2 hour trying to figure out how to get them to line up right.
This is overall a really well built unit. Installation was pretty straight forward and there was plenty of caution about how to install it such that it won't fall and drop your TV on your cat.My only criticism is that the TV is not mounted directly in-line with the wall connection plate. If you find the center of your wall and screw in there, your TV will then be off by a few inches. I wish I would have known that before I finished the installation.
Quick delivery, easy set up. We have a 55&#34; Samsung LED LCD TV (44lbs) and I wanted to get something I was confident would not only hold the weight, but also allow us to manuever the TV in any direction we wanted. This is much heaftier/stronger in person than it looks online, it is not cheaply made at all. Our walls are about 1&#34; drywall and then brick (older house), so that thing is on there super snug.
Bought this to mount my new 42 inch Insignia LED and it works like a charm. I was skeptical because of the low price and the pictures made it look like it might be a little flimsy and cheap but it is decidedly solid all around! Easy as pie to set up for anyone able to handle a drill and screwdriver.Took off  1 star for not including the paper template that was supposed to be there, but would be 5 otherwise. Don't spend $100+ at the store! Get this today!
If you are looking at this Mount for a 26&#34; tv, buy something else.This product did not come with screws to mount a smaller tv. (26&#34; TV). The mounting holes line up perfectly  with the mounting holes on the back of my TV. (the inner square).
I am pleased with this product. Just as others commented, there is a slight tilt at the top which isn't a big deal. Just a matter of using different screws. Couldn't believe this price vs. what store prices wanted to accomplish same thing. Product arrived on time. I recommend this product to others.
Easy to put together, I thought mounting was going to be alot more difficult. added the screws for 400x400. screwed into a stud in the wall, seems sturdy. Its been up for a few weeks now and No issues at all, moves where I need it.
I mounted a 42&#34; LCD to this wall mount. It simply screws into a wall stud. The bracketry and rotating arms are appropriate for my size/weight TV. The universal &#34;X&#34; mount for the back of the TV didn't block any of my connections but I could see how it possibly could on another configuration. My only real complaint is the tilting mechanism. There is no way to lock it down so my TV would travel to the down most position.
Answer: Your question is either about the screws going into the wall or the flat screen TV set back.  The screws going into the wall are in a line, with two screws at the top of the bracket slightly offset from one another.  Correct placement of the bracket over a stud is crucial for the units ability to hold up a heavier flat screen TV.  On the TV side, the receiving screw holes in the back of most all flat screen TVs form a box, or even two boxes.  For my Samsung 40 inch LED, I did not use the arms (sticking out of the four corners of the plate extending from the wall.  Use of the arms was not necessary.  For larger sets, connect the arms and secure the set to the appropriate holes in the extended arms.  The larger the set, the more likely you are to use the holes at the end of the arms.  You will use four (4) screws to hold the set against the wall and the set against the plate extending from the wall.
