What ever you decide to buy....be sure to see it ON in a store first.
Then walk up to it and then 'walk to the side' and see if the screen looks gray. We are using flat screens quite differently in an RV than in a home setting where you sit right in front of it.
SOME brands the screen goes gray or black when viewing them from below or to the side.
I got burned on my first flat screen for the MH. You had to be seated right in front of it and at eye level. Just like you do when you are at 'home'. Which is what they are designed for.
I had mine mounted up high in the MH so sadly when you sat on the couch when you looked up the screen was all dark or when you moved off to the side the same thing. :(
Best thing to do is go to Walmart or best buy where they have all of them mounted on shelves and move to the side to see if the view changes before you buy.
