How to wall mount a Bravia KDL55W805CBU

[Dabast]

Hi,

I have just purchased a Bravia KDL55W805CBU , on the Tesco website where I purchased it from it says that the stand can be used as a wall mount ,but there is nothing that states this in the manual.In the box I can see the stand(the manual doesn't tell you how to attach it even if you wantto use it as a base) ,two neck stand assembly brackets (which I don't know what they are for or how to attach them) .Two bolts that look a bit like batteries(i believe these are so that you can attach the SU-WL450 wall mount bracket which Sony seem don't sell anymore and on Amazon they are over £200 !   .But that bracket is a fixed one and I would like a wall mount that I can move around.can I  go by the vesa measurements and buy a wall bracket or do I need some kind of adaptor first ? If so which one please .

Thanks
