This TV has an excellent picture and sound. What sets it apart from other HDTVs is features that make it adapt well to varied lighting conditions. We use the TV in a sunroom where bright light comes from all sides, but the 40XV648's Autoview setting handles it beautifully, boosting the brightness enough to compensate. It also has a less-reflective screen with Crystal Coat, a feature to enhance contrast under those conditions. The Autoview dims automatically at night, but I prefer the standard or movie settings under those conditions. The TV is easy to set up without a lot of mumbo-jumbo. It handles fast action really well, too. Overall an excellent choice!
