Black Level

We measured the Sony KDL-46EX700's black level at 0.11 candelas per square meter (cd/m2). This is pretty solidly good. In fact, 0.1 cd/m2 is our current benchmark for 'pretty solidly good,' so the KDL-46EX700's black level finds itself in good company. More on how we test black level.

Peak Brightness

We measured the KDL-46EX700's peak brightness at 460.06, which is plenty bright. Not only is its luminance enough to give the TV a great black level, it's also bright enough to combat the reflections of external light. More on how we test peak brightness.

Contrast

With a good black level and a high peak brightness, the KDL-46EX700 wound up with a great overall contrast ratio: 4182:1. Our eyes sense detail based on contrast, and a high contrast ratio is a good chunk of what gives an HDTV good detailing. The other chunk is greyscale gamma, which is covered below. More on how we test contrast.

Tunnel Contrast

We didn't see any issues with the consistency of the KDL-46EX700's black levels. They'll remain fairly even, regardless of how much black is on the screen. More on how we test tunnel contrast.

White Falloff

We also didn't see any issues with the KDL-46EX700's whites. The TV will have the same peak brightness if 5% of the screen is white, or if 100% of the screen is. LCDs typically don't have issues with tunnel contrast or white falloff. More on how we test white falloff.

Uniformity

We didn't really see a lot of uniformity issues on the KDL-46EX700. There was some flashlighting at the corners of a dark screen, and some dimming around the corners of a bright one, but otherwise our model looked great More on how we test white falloff.

Greyscale Gamma

We measured the TV's greyscale gamma at 2.65, which is a bit more aggressive than we'd typically like to see. As you can see in the handy graph below, the greyscale (when plotted logarithmically) is more or less a straight line. This is good: it means there aren't any areas that progress along the greyscale unevenly, which leads to lost detail. There's a bit of a flat tail towards the darker end of the spectrum. More on how we test greyscale gamma.
