Samsung UN55C7000

Black Level (7.27)

We measured the Samsung UN55C7000’s black level at 0.14 candelas per square meter (cd/m2). This is a decent black level, but it isn’t great. Our standard for a solidly good black level is 0.1 cd/m2, mediocre is towards 0.2 cd/m2, and anything in the 0.3 cd/m2 area or beyond is pretty bad. You shouldn’t have any problems with your UN55C7000 not showing deep enough blacks. More on how we test black level.

Peak Brightness (8.57)

We measured the UN55C7000’s peak brightness at 322.52 cd/m2, which is more than bright enough for normal use. Not only should you get some brilliant whites, but you shouldn’t have any issues with external light washing out your picture. More on how we test peak brightness.

Contrast (7.49)

The TV had a decent black level and a decent peak brightness. The result? A decent contrast ratio. We measured the UN55C7000’s contrast at 2303:1, which should be more than good enough for the average viewer. Our eyes discern details based on contrast, and while contrast ratio isn’t the only factor controlling a TV’s level of detail, it is important. More on how we test contrast.

Tunnel Contrast (9.75)

We didn’t see any real issues here with tunnel contrast. For the most part, it doesn’t matter how much of the screen is black: the TV will output a fairly consistent luminance level regardless.

The one caveat is when the screen is nearly 100% black. At this point, some kind of automatic dimming will kick in, which can’t be turned off. We’re not a fan of dimming features, because they don’t actually increase contrast ratio: anything that’s supposed to be bright will lose its luster. More on how we test tunnel contrast.

White Falloff (7.28)

The TV’s auto-dim reared its head again on this test. When the peak brightness down by about 30% when there wasn’t much white on screen. Again, this isn’t ideal because it sacrifices detail in the brights in order to somewhat bump up detailing in the darks. More on how we test white falloff.

Uniformity (6.75)

This TV didn’t have the best uniformity, which is likely due to its edge-lighting. On a dark screen, the corners have some serious flashlighting issues, and the rest of the screen is really blotchy. A white screen, on the other hand, looks fine. More on how we test white falloff.

Greyscale Gamma (8.10)

We measured the TV’s greyscale gamma at 2.52, which was a bit aggressive, but not by much. If you look at the curve below, you can see it’s a bit bumpy towards black, which means there isn’t nearly enough differentiation between dark colors. Elsewhere, however, the TV performed quite well.
