Sony KDL-EX640

The Good 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.

The Bad 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.

The Bottom Line Sony's EX640 series is one of the better deals from the company, with decent picture quality and features for the price.

Review

Sony KDL-EX640

When it comes to buying a TV, no matter how attractive the shiny flagship models may be, it usually makes the most sense to buy the midrange products. While you'd naturally assume that the more advanced models have better picture quality this isn't always the case. Sometimes you're just paying for more features and a worse picture.

If you're considering a Sony LED TV and the excellent KDL-HX850 is too rich for your blood, your choice comes down to the KDL-HX750 or the KDL-EX640 I'm reviewing here. After comparing the two directly I'd say it's a pretty easy decision. The EX640 wins because its picture is actually better than that of the more expensive HX750. Despite its spot as Sony's least expensive LED TV, the EX640 offers a very tidy picture for the money, with better blacks than the HX750 and the Samsung UNES6500, and well-saturated colors. Design is a high point, unusual for a midrange model, with a nicely textured finish. The only significant feature it misses is 3D, which should actually please some people.

While the Vizio M3D0KD is better in nearly every way, if you're looking for a TV by one of the "big four" TV makers, the Sony EX640 is a good buy.
