Science Introduction

The Samsung LN40D630 may be a no-frills, entry-level LCD, but its color and contrast scores were nonetheless impressive. It displayed with smooth motion performance and its only real drawback (which is only a drawback if you're overtly picking at nits) was its viewing angle, which was still about average. The D630 is a prominent performer in basic display areas.

Contrast Ratio

A very real contrast ratio that's impressive

For an LCD TV, the Samsung LN40D630 tested with an impressively deep black level of 0.07 cd/m 2 (very bright)—by its black level. We'll save you the mental meth: The D630 tested with a contrast ratio of 5274:1. While that may not sound impressive next to gobbledy-gook numbers like "One Million-to-One," those advertised numbers exist only in the minds of marketers totally removed from reality. As an actual result based on measurable data, 5274:1 is excellent.

Color Gamut

The Samsung D630 tested with a very accurate color gamut.

A television's color gamut is a visual representation of the millions of colors it can produce. Like most consumer products, televisions have set standards for their operation and one of those standards determines the ideal setting for their color/light saturation, i.e. how their color gamut should appear.

The Samsung LN40D630 met this ideal with a high degree of accuracy, matching the primary points of red, green, blue, and white almost perfectly to the ideal gamut. This is a very good thing—one we rarely see—which means the D630 produces objectively accurate colors that will be neither oversaturated (too colorful) nor undersaturated (too light-full).
