TV on screened in porch....

[CharlestonLion]

As part of our renovations at the house, we are adding on a 12' x 12' screened porch. We are having an electrical outlet and cable outlet installed in one corner of the porch.....they will be elevated about 8 feet up on the wall. Our hopes are to have a TV installed in the near future. Has anyone ever done this before? What TVs will be best for this? It will be elevated enough so that the TV is well up in the canopy of the porch (the ceiling gets taller the closer you get to the house), so I don't think we have to worry about driving rain getting it. I do live in South Carolina however, so humidity may be a factor. Any help or pictures on what you have done is appreciated. Thanks!
