Value Comparison Summary


The Vizio SV471XVT is one of Vizio's top of the line models, which explains the price that is almost twice that of the Sony KDL-40S5100. It's also a larger television at 47 inches, versus the KDL-40S5100's 40-inches. In addition to the size difference the Vizio model brings 240Hz refresh rate and USB connectivity. The refresh rate make a big difference with motion, and for those who love fast action movies this alone might be worth the price difference. In other areas of performance, however, the Sony KDL-40S5100 offers quality as good as or better than the Vizio, so unless motion performance is very important to you we'd call the Sony KDL-40S5100 the better value here.

Blacks & Whites


This is one area where the Sony KDL-40S5100 clearly outperforms the Vizio model, it's black level is more than four times deeper than the Vizio television, which means that despite the brighter display on the Vizio the Sony KDL-40S5100's contrast ratio is almost three times better. We'll take those deep blacks and wider contrast ratio over brightness you probably won't use any day.

Color Accuracy


Both televisions did a reasonable job with color accuracy, although the Vizio SV471XVT did slightly better with RGB performance and significantly better in staying true to the appropriate color gamut. The difference here isn't great, however.

Motion


This is the area where the Vizio SV471XVT simply blows away the Sony KDL-40S5100. That 240Hz refresh rate on the Vizio makes a huge difference for motion blur, whereas the KDL-40S5100 is blurry mess. What's more the Vizio accomplishes this feat with only minor motion artifacts, whereas with the Sony KDL-40S5100 we saw things appearing on the screen due to poor processing all over the place. A clear win for the Vizio here.

Motion Smoothness 4.50 8.50
Motion Artifacting 4.00 8.50

Viewing Effects


The Sony KDL-40S5100's viewing angle was poor. That's not to say that the Vizio's viewing angle was good, it wasn't, but it was definitely better.
