I'm looking at buying this Westinghouse 42" 1080p monitor (Model # LVM-42w2). I've noticed there is no TV-tuner, which i am assuming is needed to watch regular tv. I have DirecTV satellite....what would i need to get to make watching my satellite on this tv possible. The reason i am getting this monitor, even though there isn't the ability to watch tv, is because of my PS3 and the new Blue Ray technology. I want to use the maximum ability this wallet robber has in it. Thank you.
