Hello folks, After I purchased an HD Camcorder, I'm looking for a HD TV... yesterday I went to Costco to see what they've got. I found an LG 1366 X 768 42" at a good price (2,200USD) but also a Sony bravia 40" 1920 × 1080 (3,500USD), I'm located in Mexico City, so prices are always higher compared to US. Is there a real difference between the resolutions? is the full 1080 worth the price difference? I plan to use the screen for watching Blu-Ray discs and my HV20 movies.
