Samsung LN40C630

Color AccuracyBlacks & Whites
Decent contrast ratio. The dynamic backlight hurt the TV’s performance here.
Black Level (8.77)
We measured the Samsung LN32C630’s black level at 0.07 candelas per square meter (cd/m2). This is a very deep black level, especially for an LCD. More on how we test black level.

Peak Brightness (9.04)
According to our instruments, the LN32C630 is capable of outputting a maximum luminance of 369.15 cd/m2. This is bright enough to ensure your picture doesn’t get washed out by external lights, and also a high enough ceiling to allow for subtle details in very bright scenes. More on how we test peak brightness.
Contrast (9.28)
With a great black level and a high peak brightness, the LN32C630 has a very high contrast ratio. We measured the contrast at 5273:1, which is incredibly high—especially for an LCD, which typically have higher than average black levels. Our eyesight is based on contrast, so a high contrast ratio is essential for ensuring a high level of detail in your picture. More on how we test contrast.
Tunnel Contrast (9.49)
It looks like the TV has an automatic dimming feature that kicks on when the over 90% of the screen is black, but otherwise the TV maintained a very consistent black level. More on how we test tunnel contrast.
White Falloff (8.58)
As mentioned above, when the majority of the screen is dark, the screen will dim. This has an effect on the peak brightness as well. While this feature is a bit annoying and can cause a loss of detail in bright areas, the TV has a very consistent brightness elsewhere. More on how we test white falloff.
Uniformity (8.25)
We only saw minor issues with the LN40C630’s screen uniformity. On an all-black screen, you can clearly see some lighter blotches scattered around, and the corners and sides have some flashlighting. An all-white screen looked pristine. More on how we test white falloff.
Greyscale Gamma (6.65)
The LN40C630’s greyscale gamma is a bit too aggressive, meaning dark greys brighten too quickly. An aggressive greyscale gamma can result in fewer visible details. This is especially true for the dark end of the spectrum: that flat little tail at the bottom means dark colors will all be crushed into flat black. More on how we test greyscale gamma.
