I have a 296bhs but it looks like the same bedroom/bathroom layout as yours.
I installed a Samsung UN22F5000 22-Inch
. The limitation you have is not wanting to take up too much space because of the walkway between the foot of the bed and the wall. Too big of a tv or at least one that sticks out too far will interfere with that walkway.
I mounted mine up towards the ceiling so that my shoulders and body would not be able to bump it (be careful because the board for mounting the tv inside the wall does NOT go all the way to the ceiling as I found out). I should note that this TV leaves maybe 2 inches on the bathroom door side and maybe 3 inches on the hallway side. I also had to add two mounting points for a strap to hold it down while traveling.
I probably could have gotten it tighter to the wall but I put it on this articulating arm.
