LG 55LE5400

Blacks & WhitesNext: Page 4
MotionColor Accuracy
Outstanding RGB color curves. Minor color temperature consistency issues.
Color Temperature (7.72)
The LG 55LE5400 showed some minor problems with color temperature consistency. As the signal intensity decreased, the colors warmed, as you can see in the chart below. However, the problem was not egregious. In fact, it only occasionally strays into the realm of ‘human perceptibility.’ More on how we test color temperature.

RGB Curves (9.36)
The RGB curve test determines how well the TV transitions from shadows to highlights in each of the color channels. On the whole, the LG 55LE5400 showed a strong performance. The curves are extremely smooth. LG has a history of excellence in color testing (though offset somewhat by the poor black level).
There’s clearly some lack of detail in the shadows, but that’s normal. There’s also some very minor loss of detail in the highlights, which we call peaking. Again, though, the LG 55LE5400 did much better in this test than many TVs. More on how we test RGB curves.
The strips of color below are digital recreations of the test data above, compared with the results from other TVs.

Color Gamut (6.07)
The LG 55LE5400 performed rather well in the Color Gamut test, which matches its performance up to the rec. 709 color standard. The red and green point align almost perfectly. The green point is a little off, as is the white point (the circles in the center). More on how we test peak color gamut.
The table below contains all the numeric details of the LG 55LE5400’s color gamut performance, compared to the rec. 709 standards.
