I bought this mount for a 37 LG flat-panel. Even though it states it will fit up to a 37-incher, the wall plate and the mounting brackets fell about 4-6 short. I don't know if the LG is wider than standard but make sure you measure the mounting holes on your screen before purchase. This in no way takes away from the quality of the product. I'm still giving it a 10/10 because the cheapest I've seen a comparable mount is $90, and the metal wasn't as solid on that one. This compares with the $150-200 ones.
I have a Olevia 542i 42 LCD which weighs in around 85-90lbs w/o the stand. I ordered this one from Monoprice.. the bolts that come with it will work M6 but you have to use the nylon washers included. I went to Lowes and got smaller M6 which work perfect. Mount was easy to put on wall and is perfectly hidden behind my LCD. I priced similar wall mounts local.. over $100 everywhere I went.. I looked in the boxes.. almost identical in manufacture. Highly recommend this mount.. A+++
