LG 47LK520 LCD HDTV Review

Color Temperature

Keeping a consistent color temperature was difficult for the 47LK520. There are two major peaks that take up most of the spectrum, showing significant error. The darkest end of the spectrum will be noticeably tinted orange because the temperature of the light gets too warm at this brightness. As your picture goes from the dark end to the middle range of the spectrum, the error switches, and your picture will take on a blueish hue.

Though there is perceivable error over most of the spectrum, neither of these peaks are strong enough to ruin your watching experience, but you may notice tinting in some images. More on how we test color temperature.

RGB Curves

Great curves on this model, is something you might say at a fashion runway, but it definitely applies to the LG 47LK520. All three graphs of the primary colors are in line with each other, fairly smooth and reach from 0 to 100% luminance with only a little bit of a flat line near the brightest end of the spectrum.

This shows us that the colors are consistent, not one brighter than the other, that the entire range is being used to produce pictures due to the smoothness of the line, and that there is very little peaking where colors cannot be any brighter. More on how we test RGB curves.

Below are graphical representations of the color curves above, matched against the ideal response.
