I'm looking to get an HDMI cable for my Xbox 360. I've never needed one before so I don't know anything about them. I would appreciate some help with my questions before I make a purchase. In parenthesis I've related my questions to TVs to better explain the question I'm asking. 1. What features or attributes differentiate HDMI cables? (TV ex: screen size, resolution, refresh rate) 2. Of these features, what is considered good and bad characteristics?(TV ex: 720p, 1080p, 100,000:1) 3. What are good brands? What are the best brands? Thanks in advance for any help!
