Summary: Sony's EX640 series is one of the better deals from the company, with decent picture quality and features for the price.
Pros: The relatively affordable Sony EX640 offers deep-enough black levels for the money and commendable color saturation. The design is attractive and the menu system is easy to use.
Cons: We detected a couple of uniformity issues, black areas can look blue under lights, and shadow detail isn't up there with the better TVs. The wireless dongle takes up a USB port. The SEN portion of the Smart TV interface is so slow that it's kind of a waste.
