Panasonic TC-L37X2 LCD HDTV Review

Color Temperature

The Panasonic TC-L37X2 showed some slight issues with maintaining a consistent color temperature. As you can see from the chart below, as it dips into the shadows, the color temperature cools considerably. But because it's only a small portion of the spectrum, we didn't score it too harshly. More on how we test color temperature.

RGB Curves

As we stated earlier in the review, the Panasonic TC-L37X2 forces you to choose a poor contrast ratio in order to get acceptable color performance, or better contrast ratio with terrible color performance.

Look at the charts below. This first performance chart is the result of using the default contrast setting, which was relatively high. The red and blue channels are awful, and can display no details between the mid-tones and the peak brightness.

RGB Curves with Contrast Set Higher

The second performance was taken with the contrast setting fairly low, and as you can see, the curves are smooth and uniform. More on how we test RGB curves.

We consider color performance to be more important that contrast ratio, though manufacturers may try to convince you otherwise with unrealistic, million-to-one contrast ratios. But at least you now know what your options are with the Panasonic TC-L37X2, should you choose to purchase it.

The color strips below are digital recreations of the performance (based on the better color performance).
