Black Level
None of the LCD TVs we've reviewed from LG for the last year have done well in the black level tests. The LG 32LK330 measured a deepest black of 0.41 cd/m2. As you can see in the chart below, the slightly more expensive LG LK450 series didn't considerably better, and the Toshiba smoked them all (though the Toshiba failed to show any detail in those deep shadows). More on how we test black level.
Peak Brightness
The LG 32LK330 has an incredibly bright peak brightness of 395.77 cd/m2, which beat all the TVs we pulled in for comparison. More on how we test peak brightness.
Contrast
The LG 32LK330 has a rather mediocre contrast ration of 956:1. That pales next to the three TVs in our comparison pool. It's also quite a bit less that the 50,000:1 contrast that LG advertises, though those numbers are always grossly exaggerated. To give you a sense of scale, the best LCDs we've reviewed tend to fall between 4000:1 and 5000:1. More on how we test contrast.
Tunnel Contrast
The LG 32LK330 has no trouble maintaining a consistent black level, no matter how much or how little black is on the screen. More on how we test tunnel contrast.
White Falloff
The LG 32LK330 produces a perfectly level peak brightness, regardless of the screen content. More on how we test white falloff.
Uniformity
We were quite pleased to see that the LG 32LK330's screen is perfectly uniform in regards to luminance. There were no hotspots or dim corners. More on how we test white falloff.
Greyscale Gamma
The greyscale gamma test measures how well the LG 32LK330 transitioned from black to white within the greyscale. Look at the chart below. What we're looking for is a smooth response curve with an upward slope between 2.1 and 2.2. In regards the smoothness, the LG 32LK330 did pretty well. There are a couple very small hiccups in the lower left. This indicates that the gradients in the shadows may not be perfectly even, but we've not seeing any major problems. Secondly, the measured slope was 2.76, which is too steep. It means that the TV is missing some of the finer gradations. Overall, though, it's a good performance. More on how we test greyscale gamma.
