1. Did I get a good deal? http://www.bestbuy.com/site/olspage...CategoryId=pcmcat95100050044&id=1134703181720 $575 for display unit with two dead pixels. 2. The TV says its highest resolution is 1366 × 768 yet it is capable of 1080i. I thought 1080i had 1920 × 1080 resolution, or is it more complex than that since it's interlaced? 3. There is a single USB port on the side labeled "service." What is this for, and what sort of cool things could I do with it? (ex: run programs or video off USB drive, install new firmware, etc.) Thanks!
