Yes indeed. The sticker shock you're experiencing usually does translate to better performance. The priciest TVs are full-HD 1080p (the highest resolution). Less-expensive 720p sets still deliver an outstanding picture, and most high-def TV service is 720p or 1080i, but 1080p is your best bet for watching Blu-ray movies and for smoother up-close viewing. Telltale measurements such as contrast ratio (the range of bright to dark colors — look for at least 3,000:1) and the refresh rate (which reduces motion blur) can also improve demonstrably as the price increases. A 60-hertz refresh rate is common, but 120 hertz provides smoother fast-action rendering for sports.
