I'm setting up a room where there's 2 samsung ln52b550's on the wall and i was wondering if in the harmony setup i needed to have 2 tv devices or would one suffice? I want them to both show the same thing at all times and think one would be enough but figured I'd ask. Thanks guys.

As long as there is a direct line of site to both TVs, 1 remote will do the trick. Reason being is because they are running on the same i.r. codes.

Edit: Sorry read your question wrong. You only have to set up 1 device while programing the remote. My previous explanation still applies.

The problem I see arises when one of the sets inevitably gets out of sync with the Harmony. Hitting help won't really "help." :)
