Sample reports are shown below. Each is based on an actual case (or
job), though the name was withheld. These reports are shown for
informational purposes only. Please keep in mind each television has it's
own personality and limitations. So your display may not exactly match
what is shown below. In most cases the Pre-calibration performance will not match your
Interpreting the sample reports:

Grayscale comes down to x and y coordinates in a 2D space. The
target is x=0.313 and y=0.329. This specific coordinate is called D65.
Grayscale is usually calibrated in a bright screen and dark screen, though the
grayscale performance is measured over the entire 0-100 IRE (black--> white)
range. The calibrator considers performance over the range when making
adjustments. As you can only adjust it in two places, compromises must
usually be made. The art involved and experience of the calibrator
determines where to make these compromises. In general you work to
Color temperature is derived from the x,y color coordinates. So you
can actually have correct color temperature 6500K but the wrong color
coordinates! Anyway a value above 6500K is considered cool (blue) and a
value below 6500K is considered warm (red). Think of color temperature
as the symptom and color coordinates as the cause.
Delta E is a measure of color error. A Delta E<=4 is considered
Gamma is a measure of the rise in brightness going from black to white.
A gamma value range of 2.2<Gamma<2.5 is considered good. Personally I
like to shoot for 2.2<Gamma<2.35 if possible.
Contrast ratio is a measure of white/black contrast. The higher the
number the more apparent contrast.
