Quoted from PoMC:Outdoor TV? Those are called iPad/tablets. Run the app or site from your TV provider and access all TV.
Definitely want to have a 55 inch screen to watch sports and then still use a tablet to surf during commercials!!
As for the OP question, don't buy an outdoor tv. I've had my 55 inch samsung outside for over two years now and no issues at all. Now it is covered by a roof but the sides of the room outside are completely open (it doesn't get directly hit though with rain, etc). No issues yet!
