Have a medium sized flat screen outdoors, it's under the lanai roof line and I've had no problem with humidity. It's been out there about three years. Cable boxes don't seem to fare well, at least on our lanai. Have had a couple and they just go "bad" so to speak. Comcast doesn't seem to have any problems with them being outside, protected from rain because the last time the box outdoors went belly up, the Comcast repair technician worked on it on the lanai and finally replaced the one that "died." When that one passed on, we decided we weren't watching that much tv outdoors so we just stayed with the basic channels and whatever HD channels the tv picked up. Also have a DVD player outdoors and it doesn't seem to be bothered by the humidity.
