OK, figure this is a good place for knowledge about a lot of different things.
I recently moved to a new house, the prior owner left behind a wall bracket, similar (though perhaps not exact) to this:
As you look at the picture, they only left behind the part that actually connects to the wall. The parts that connect to the TV and then mount on the bracket are presumably with them (or in the trash somewhere, they certainly weren't left behind for me).
anyhoo, under my current setup, I have a 36" or so TV that is a few years old, my plan is to move that upstairs into the bedroom where we no longer have a TV and replace that one with something bigger (I'm thinking somewhere in the 48" to 60" range). Now assuming that the bracket left behind is long enough to support a TV of that size (right now I'm guessing that it is, but haven't actually measured it to compare the size to the specs of different sized units yet) does it matter which manufacture I purchase the pieces from that hook on to the TV than hook on to the bracket already mounted on the wall? I can't find a listed manufacturer anywhere on the bracket, so I have no clue who actually made it.
I guess what I'm getting at, is how universal are the arms that attach to the TV then are mounted on the bracket? Will any company do or do I need to match the same manufacturer as the bracket current sitting on the wall, short of changing out the bracket. My fear is that getting a new wall bracket will prove to be difficult or at least time consuming so if I can just use the arms from a new set, mount them to the TV then hang it on the existing bracket it would go pretty smoothly. This isn't something I plan on doing this weekend, but probably in the next 6 months, so I figured I might as well prepare myself as much as I can. If anyone has any advice, I'd greatly appreciate it. TIA.
