Color Temperature (7.1)

The Samsung LN40B530 produced an even color temperature from very bright light down to fairly dark shadows. But, as the chart below illustrates, when the picture got too dark, the color temperature became quite warm. Because this unevenness happened at the extreme end of the scale, we did not penalize it much. You probably won't notice the issue.

RGB Curves (8.23)

The Samsung LN40B530 produced good, smooth RGB curves. Practically speaking, this means that color gradations will appear smooth and unbroken. A poor performance – one with lots of bumps or stair-stepping in the curves – would appear as color banding on your screen. The Samsung LN40B530 is not the best of the comparison models (that award goes to the Samsung LN40B650), but we were satisfied.

Color Gamut (5.75)

The color gamut test measures how well the Samsung LN40B530 holds up to the international standard, Rec.709. Just so you know, we've never seen a TV that can perfectly match the standard, and we probably never will.If you look at the tips of the triangle in the chart below, you'll see that the Samsung LN40B530 undersaturated the greens, but matched the blues and reds extremely well. The white point – the circle in the center – leans slightly towards the reds, but only slightly.
