JVC DLA-RS10 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	6553K (very dark gray)
30 IRE	6489K (dark gray)
40 IRE	6538K
50 IRE	6695K (medium gray)
60 IRE	6595K
70 IRE	6582K
80 IRE	6544K (light gray)
90 IRE	6470K
100 IRE	6472K (white)

Now that's pretty impressive, with a range of only 225K from 20 to 100 IRE! It is, by the way, even slightly better than we were able to get out of the RS20

Gamma settings:

The gamma controls on the RS10 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. B 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. In fact, it averaged 2.19 in his measurements.

JVC DLA-RS10 RGB Settings

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

Color Temp settings:
Gain
Red	0
Green	-9
Blue	-50

Offset
Red	0
Green	0
Blue	-1

Adjustments for Dynamic Mode

Dynamic offers a bit less control, with only Offsets. Mike's results recommend these:

Offset
Red	0
Green	-2
Blue	-5

Post calibration brightness is not much different than before. In Cinema 1, we measured 740 lumens, up slightly from 710 lumens. In Dynamic mode, brightness dropped, also insignificantly, from 814 lumens to 799 lumens.

Dynamic mode above shows color saturation at +10. That assumes you are fighting ambient light. Dial down as needed. With no ambient light issues, you might find yourself back at 0.

If these combined settings work as well in your JVC DLA-RS10, as they do in this one, you are going to love your RS10! As much as I've enjoyed my RS1 (with even less color control), this RS10, now adjusted, definitely looks better (not drastically, but better, none-the-less! Once again, 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 deliver improved performance!
