This is what i bought for mine, i highly recommend it.

I wanted mine to be adjustable, set it to 8 degreees down and mounted it, but once on adjustment is a pain. Not only that you don't need to adjust it and the adjustable ones sit further from the wall.
If its a modern LCD, it doesn't matter anyway, i can see mine from any angle with complete clarity as i'm sure you can. Get a non adjustable one that sits parallel to wall at a distance of about 22mm as opposed to 70+mm.
