Ideally, this display would essentially result in a waveform showing identical
RGB components corresponding to the grayscale monochrome bar spectrum
being fed to the set monitor. However, as shown in Figure 3-7 with no
correction applied, the waveform monitor shows imbalance between the RGB
channels due to the reasons discussed above. Note the excessive offset, level,
and deviation from an ideal gamma curve for the blue channel.
