I just got my Sammy on Saturday and I am not sure I am as blown away by the PQ as I had expected to be. How would I know if I have a defective one? Everything appears to be working properly. HDNet is not blowing me away. ESPN HD Vikes/Bears looked mediocre to me. Source is a Sony HD-200 via DVI. Any tips to decide if my sammy is working properly would be appreciated! FYI - Software is dated July, 2003. I don't recall the version.
