JVC DLA-RS20 Projector Calibration and Settings3

JVC DLA-RS20 Post Calibration Grayscale

Here’s what we ended up with in measuring the grayscale. All the Color Temp and CMS settings are listed further down. Since then I have made minor changes to the color temp settings. I have not remeasured, but these should be close to our most recent best settings.

That’s not by any means exceptional tracking of the color temp, but it is a very reasonable one. More importantly oversaturation of individual colors has been dealt with, and the bottom line is a much better image than you will see on other projectors that track a little closer to 6500K.

Gamma settings

The gamma controls on the RS20 allow for detailed customization, including different gamma curves for each primary color! So far I’ve only tinkered there. I have found the provided gamma presets B and C to do a very good job, although I definitely prefer B for most content, C seems to work well for the rest. My personal favorite overall, is the B gamma setting. It provides a little extra pop to the image in most scenes, and looks great, doing it, while still maintaining a very film-like image.

Overall, Mike reports that the B gamma is very close to the ideal 2.2 over most of the IRE range. C averaged a bit high at 2.32 gamma, which gives you a bit darker image in the mid-range IREs.

JVC DLA-RS20 RGB Settings

These are the adjustments we made to Red, Green and Blue for the grayscale balance of Cinema 2 mode. This is accomplished by placing these adjustments into one of the three Custom settings (1, 2, or 3)
