JVC DLA-RS20 Projector Review
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.
|20 IRE||6418K (very dark gray)|
|30 IRE||6540K (dark gray)|
|50 IRE||6792K (medium gray)|
|80 IRE||6557K (light gray)|
|100 IRE||6423K (white)|
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.
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)
|Red||H= -2||S= -23||B= 9|
|Yellow||H= 3||S= -25||B= 15|
|Green||H= -10||S= -25||B= 18|
|Cyan||H= -1||S= -30||B=12|
|Blue||H= 0||S= -10||B= 15|
|Magenta||H= -1||S= -12||B= 10|
That’s it folks. If these combined settings work as well in your JVC DLA-RS20, as they do in this one, you should be most pleased! A most impressive picture! Once again though, please consider that, with a projector in this price range, the cost of a good calibration is not a significant additional expense. More to the point, proper calibration will really deliver improved performance!
