Color Accuracy Summary
• Good color temperature.
• Above average color representation.
• Slight issues with gamut accuracy.
• Calibrated using DisplayMate.
Color Temperature (8.52)
When we calibrate our TVs, we try to get their as close to the 6500k ideal as we can. On this test, we measure how the color temperature fluctuates along the greyscale. Ideally, it'll remain as close to 6500k as possible throughout the spectrum.
On the graph below, the green area shows the limit of perceptibility. Unless you have superhuman color detecting skills, you won't notice any changes that occur in that green area. The degree to which the line veers outside the green is indicative of how obvious the color shift will be.
The 37LH30 didn't have any major problems with this test. There were some minor fluctuations along the way, but they were so minor that they're not really noticeable.

RGB Curves (7.94)
Overall, the LG 37LH30 had good color representation.

Reds had some minor issues. They don't have much of a low-end, intensify too quickly, then hit a slight peak.

Green is a bit choppy in its representation, but doesn't peak. Like the reds, however, it also doesn't have much presence in the low end, followed by too much emphasis too quickly. As with the reds, these issues are minor.

Blues take the worst aspects of both the reds and greens and combine them. The graph is a bit choppy, it peaks, it doesn't bottom out in the low end, and it increases in intensity too fast. Again, however, none of these issues are particularly significant.

Color Gamut (6.17)
The 37LH30 had a fairly accurate color gamut. The greens and reds are close to Rec. 709, which is the international standard. The blues are slightly off and a bit oversaturated.

For those who like such things, below are the measured coordinates of the Rec. 709 gamut and the 37LH30's measured gamut.

| Red | 0.4488 | 0.5236 | 0.0020 |

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...
