It is officially football season, and whether you host regular game parties or just want to relax and enjoy your favorite team getting absolutely trounced yet again, it's best to make sure your TV and the rest of your system are at their best. Consider this a fall tune-up for your A/V system. It's also a good time to consider upgrading. Some of our best TV picks are bigger, brighter and often have better image quality than TVs from just a few years ago. They're often cheaper, too.
