Started this thread for calibrating the Viewsonic Pro8200.
Farthest Throw Native On/Off 2,304:1
Native On/Off maxes out around 2000:1 to 2500:1 at best case, but generally is in the ranges of 1500:1 to 2000:1 in most peoples' setups.
FACTORY DEFAULTS - PRE-CALIBRATION MEASUREMENTS (2600 Hours on Lamp, only changed saturation, brightness, and contrast)
By looking at the PRE-CALIBRATION charts above, we can see by default that the image is too cool but the reason it is has gotten this cool is because of my LAMP wear (2600 hours on a lamp is a lot different than a new lamp). However, it's not as bad as the graphs make it appear to be. Too cool of an image is easily the most bearable compared to say too warm. Furthermore, the gamut is not bad at all, because the three primary colors (Red, Green, Blue) are very close by default. The secondaries (Cyan, Magenta, Yellow) are a bit farther off. The white point error is off because the gray-scale is off. The default GAMMA is still impressive, even with 2600 hours on the lamp, the Gamma Preset 1 measures almost exactly 2.22, with a slight bump up between 70-95 IRE (which many would argue is beneficial anyhow). Only Magenta and Cyan are off enough on the Gamut to really worry about calibrating the gamut (well yellow as well a tiny bit). Even though the image is too cool, it still doesn't look bad at all in the default mode overall when watching it (given that the luminance, gamma, and gamut is pretty good, though gray-scale is too blue).
Now let's look at the POST-CALIBRATION (editing, adding in one sec)...
Pretty Close to Perfect even after 2600 hours on the lamp. Post-calibration the gamma has a couple bumps in it, but as long as it does not drop below 2.1 (which it does not), then it is fine. Keep in mind these charts are showing only TINY errors overall because the range of error it shows is very small. Some of you may need to calibrate to an image with a bit more blue in it to overcome Red/Green. I took my time with this one and the GAMUT is really good (most colors are perfect).
