Color Accuracy Summary
Editorial Note: This is a review of the Samsung UN46B8500. Test results are for this model, but should indicate the general performance of other sizes in the UNxxB8500 series. The UNxxB8500 series includes the following models: UN46B8500 and UN55B8500. Read here for more details on series differences.
• Consistent color temperature
• Smooth color curves
• Testing done using DisplayMate Software
Color Temperature (9.35)
This test measures how well the TV can maintain a consistent color temperature, regardless of how intense the source signal gets. In the best of cases, you'll see a chart like the one below. The picture gets a little warm or a little cool, but it rarely strays into the range of 'perceptible' to humans. Only at the end, in the very brightest signal, does the temperature spike.

RGB Curves (8.07)
This test looks at how well the TV can produce every shade of green, then red, then blue. What we're looking for here is a smooth curve, Every little stair-step is an instance where, in real life, you could expect to see color banding. And that flat bit at the top on the right-most edge... that's the Samsung UN46B8500 peaking out, unable to produce detail in the very brightest values.
Overall, this is a very good performance and a high score, compared to the top performers from other manufacturers.

The color strips below are digital recreations of how the televisions performed when required to produce the entire range of the red channel, green channel, and blue channel. What you want to look for here is evenness and enough detail in the shadows. Clearly, none of these TVs match the ideal response, but theSamsung UN46B8500 stacks up very well.

Color Gamut (4.22)
The Samsung UN46B8500's performance was matched up a popular color standard called rec. 709. As you can see from the chart below, the TV could match up to the red point of the triangle, but the green and blue were noticeably off. Also, the white point (circle in the center), leaned towards the greens.

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...
