At what size screen can one notice the difference between 720P vs. 1080p?
Screen size isn’t the only thing that determines whether you can distinguish a 720p from a 1080p image. The distance you sit from the screen also comes into play. For example, with a 50-inch display, you’d have to sit less than 10 feet from the screen to hope to notice a difference. So, in general, it’s not likely to be an important issue in your home theater unless you’re using a front projector.
Current programming sources available in 1080p include HD-DVD and Blu-ray Disc. What comes next? Probably, eventually, 1440p, 2160p, and 4320p. But I certainly wouldn’t base ANY buying decision on availability.
