Sony Bravia KDL-40NX700

Blacks & WhitesNext: Page 4
MotionColor Accuracy
Good performance, overall. R, G, and B channels out of sync.
Color Temperature (9.89)
The Sony KDL-40NX700 maintained a solid color temperature across the range of signal intensities. As you can see from the chart below, the whites turn a little blue, but these blues barely poke their head into the range of human perceptibility, so you probably won’t notice. More on how we test color temperature.

RGB Curves (8.22)
The Sony KDL-40NX700 showed a relatively strong performance in its RGB curve test. You can see in the chart below that the channels do not move in perfect unison. The red channel shows a little more detail in the shadows, but it peaks out early, losing detail in the highlights. The blue channel is the darkest, but also peaks out early. Only the green channel had a smooth curve from bottom to top. More on how we test RGB curves.
The strips below are digital recreations of the color curves in the chart above. They’re an approximation of what you’d see on the screen if there was a red or green or blue strip running the gradient range across the TV’s screen.

Color Gamut (4.18)
The Sony KDL-40NX700 matches up only decently to the rec. 709 color standard. You can see in the chart below that the green measurement point matched up quite well, but the red point was a little undersaturated, as was the blue point. The white point – those two circles in the center – were pretty closed matched. More on how we test peak color gamut.
The table below contains all the numeric details of the Sony Bravia KDL-40NX700’s color gamut performance, compared to the rec. 709 standards.
