Hi I need to mount this 50" TV on a corner. Only thing is it will be offset a little rather than coming out an equal amount from both sides. See photo HERE The wall to the left is made of concrete blocks and the wall to the right is a stud wall. I was going to use a 'corner mount' - something like this But I am not sure if it will work as I need unequal amounts on either side (if you see what I mean). I am also worried about adjustiability as I would like to be able to move it a little to get the final position perfect after screwing the bracket to the wall. Only other alternative is to get a really long articulated arm from the left side but I wonder if this would be putting too much strain on it.
