Insignia NS-42L780A12 LCD HDTV Review$599.00
The color temperature of the Insignia NS-42L780A12 was nearly perfect, spiking out of the margin of perceptibility at one small area only. In theory, you should be able to see it, but since it's so close to the margin and only happens for the brightest white, it's going to be unnoticeable. More on how we test color temperature.
The individual RGB curves of the Insignia NS-42L780A12 were very smooth. This indicates a smooth transition during gradients, which can show color bands in lower quality TVs. Each of the colors ends in a peak, which means that detail will be lost in the brightest shades, which will display as a flat color. The problem is not too bad, however. Additionally, the saggy nature of the curve means that darker shades of color are crushed into black. More on how we test RGB curves.
Below, we have reconstructed examples of what the individual RGB gradients would look like on the Insignia NS-42L780A12. You can compare these results with those of a few competitors. Note the effects of black crush and peaking discussed above.
