Color Accuracy Summary
Editorial Note: This is a review of the Vizio SV470XVT1A. Test results are for this model, but should indicate the general performance of other sizes in the SVxx0XVT1A series. The SVxx0XVT1A series includes the following models: SV420XVT1A and SV470XVT1A. Read here for more details on series differences.
• Excellent color temperature consistency
• Decent RGB curves
• The blue channel peaks too early
• Testing done using DisplayMate Software
Color Temperature (9.87)
The color temperature test measures how well a TV can maintain a consistent color temperature across the signal range, from shadows to highlights. From the graph below, you can see that the Vizio SV470XVT1A barely strayed into a 'perceptible' error until the signal was very, very bright. This is an excellent performance.

RGB Curves (7.96)
The color curve test is a fairly long and comprehensive. In a nutshell, we go through each of the three channels – red, green, and blue – and produce every level in that channel, from 0 to 255. Measurements are taken to determine the accuracy of the TV's performance, so that we can see how smoothly a TV can ramp up.
From the graph below, you can see that most of the Vizio SV470XVT1A's color range is smooth. Yes, we see some flattening out in the lower left, meaning you're going to see some loss of detail in the shadows (several other tests confirmed this weakness). Then there's the more obvious problem in the upper right side. The blue channel peaks up pretty early, ceasing to retrieve any detail after a certain brightness level. The red channel is only a little better. Only the green channel produces smooth detail all the way up to the brightest possible signal.
Overall, the mid-tones are smooth, but the score was hurt because of weaker performance in the shadows in highlights.

Color Gamut (5.92)
The Vizio SV470XVT1A performed reasonably well when its color performance was held against the rec. 709 color standard. The green point is a little oversaturated, as is the blue. The red channel, however, matched up well. The white point, that circle in the center is quite a bit off, shifted too far into the blue.

Samsung UN32D5500 LED LCD HDTV Review
The D5500 has a rather high MSRP of $699, considering it’s only a 32-inch TV. There are some “premiums upgrades,” a term we use with some dubiousness, knowing that these features can be far less valuable than they appear. Nevertheless, at its core this is a good television. If you can find it a significantly reduced price it would make a great addition to a home theater. Read More...
