Color Accuracy Summary
Editorial Note: This is a review of the LG 47LH90. Test results are for this model, but should indicate the general performance of other sizes in the LH90 series. The LH90 series also includes the 42LH90 and the 55LH90. Read here for more details on series differences.
• Good color temperature.
• Average color representation.
• Accurate color gamut.
• Testing done using DisplayMate Software
Color Temperature (8.47)
In our calibration, we try to set the TV's color temperature to the ideal 6500K benchmark. While it's important to establish an accurate color temperature, it's significantly more important for the TV to maintain this level throughout the greyscale. If the temperature shifts around, it makes calibration less about achieving perfect picture quality and more about minimizing inaccuracies.
The TV had a pretty solid color temperature overall. About halfway through the color gamut, the temperature starts to rise, but doesn't exit the perceptible range by a distracting amount.

RGB Curves (7.94)
Since red, green, and blue make up each other color on your display, their individual performances are quite important. Because of this, we test them separately. In the below graph, we've plotted each color's performance throughout the greyscale.

The 47LH90 did well on this test, but didn't exactly wow us. As you can see above, the lines weren't particularly even. This means fine details are getting lost, due to the inadequate differentiation between similar colors. The colors' slopes also don't leave enough room for progression in the middle of the spectrum.
Below we've compared the 47LH90's red, blue, and green performances alongside the performances of several competing televisions.

Color Gamut (4.65)
The colors a television displays are supposed to follow an international standard, rec. 709. Very few do, however, which is why we perform this test. Typically the issues we see involve the TV overemphasizing certain colors, but it looks like the 47LH90 under-saturates its green and red.

Below is a chart of the rec. 709 points for RGB and white, along with where we measured these points on the TV. Chances are, if you aren't a cinephile, you won't care that much about this chart.

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...
