MotionColor Accuracy
Solid color temperature. Inaccurate RGB curves.
Color Temperature (9.39)
The LG 60PK750 did a great job with maintaining a consistent color temperature. There were barely any perceptible shifts at all. More on how we test color temperature.

RGB Curves (6.48)
The graph below describes how the LG 60PK750’s red, green, and blue channels perform across their full spectra, from most intense to black. As you can see, the curves aren’t very smooth at all. There are lots of little bumps along the way, each of which indicates a loss of detail. The curves themselves also indicate a poor performance: this should be a smooth, convex curve, not a diagonal line. The curves’ flatness indicate middle-intensity colors have too much differentiation between them and the high-intensity colors don’t have enough differentiation. This being said, neither of these flaws is pronounced enough to indicate a horrible picture quality. We’d say the LG 60PK750’s color representation was a bit below average compared to other top-of-the-line HDTVs. More on how we test RGB curves.
Below we’ve graphed the LG 60PK750 along with some competing HDTVs. Keep an eye out for any instances of vertical banding, which indicate a loss of detail. Also, make a note of how smooth or sudden the transition to black is, and where the black point seems to occur: the larger spectra offer the greatest amount of detail.

Color Gamut (5.26)
Each TV’s color gamut is supposed to adhere to an international standard, called rec. 709. Even though adherence to this standard is mandatory, TVs rarely emulate it perfectly. The LG 60PK750 came close on the red and green points, but the blue point is both undersaturated and shifted out slightly. The white point, on the other hand, is nearly spot on. The 60PK750’s performance is about in line with other TVs in its class. More on how we test peak color gamut.
The table below contains all the numeric details of the LG 60PK750’s color gamut performance, compared to the rec. 709 standards.
