A:AnswerWell it depends how you attach te holding plate to the TV. There are metal extensions provided in the package that allow you center the TV wherever you want. Some scenarios will need the position tv a little upper or lower depending of your needs and is when you have yo use those extensions, that's why the mount doesn't move up or dow itself.
A:AnswerIt clearly specifies up to 39" tv However check the weight capacity in the specifications and if you Tv is below the
max weight you should be fine
A:AnswerMy guess is that you could make it would work, but you should probably go with the larger option. I would never recommend a TV larger than the specification for the mount. The extra little bit you spend could save you in the long run if the mount fails.
A:AnswerThe description states 19 - 39 inches so while it's possible it may fit, I wouldn't suggest trusting it to hold the size that it's not approved for.
