Pro8100 Calibration and Benchmark Video Testing
I would classify the
"out of the box" performance of the ViewSonic Precision Pro8100 as good,
but not excellent. We were, however, able to get an excellent result after
calibrating the system with our datacolor ColorFacts
software.
Of first note, the CIE chart looked very good on this projector, with solid performance on red and blue and only a slight deviation (towards yellow) on green. This is a better color response than I've seen from many competing products in this price range and above.
Comparing Calibrations Results Before and After
When performing calibration it's important to turn off any Auto Iris functions. The results will not be consistent, nor correct if you leave it on and what will invariably occur is a resulting S-type gamma curve. Looking below we see the before and after gamma measurements.
Before we measured a Gamma of 2.42 (left); After calibration yielded a Gamma of 2.33 (right)
If you leave the Auto Iris on (don't do this), this is what you will end up with following calibration:
Holy
wiggly line, Batman!
Color temperature wasn't awful before calibration, but got much better with a custom RGB calibration:
Before calibration (left); After calibration (right)
Color temperature dialed in nicely as well:
After calibration we dialed in the color temperature much closer to our 6500K
target.

We didn't have much to say about the results, but the on-board HQV Reon-VX system did what we would have expected it to. We were happy to see noise reduction that worked, though if you overuse it you're clearly going to run into some potential issues. What nice about a decent score in this area is that you can safely feed it interlaced standard definition television/cableTV content and know that it will do its best to render it efficiently.
