I was able to use a standard VESA mount. The tricky part was finding the correct mounting screws. I believe that M4-0.7mmx10mm was the one that ended up fitting the lugs on the T.V. It sure would have been a lot easier if the screws had been included.
One is a gloss black finish, one is the brushed finish. The gloss finish has been out of stock since I think December (I had it on order). I cancelled that order and placed an order for this on on Sunday. It arrived on Tuesday.
