JVC RS15 Gamma settings:

The A setting lifts the brightness in the very darkest areas, making dark shadow detail more visible, but, by doing so, removes a small amount of the punch on very dark scenes. B setting mostly lifts brightness in the 40 to 80 IRE range. It adds punch and also makes those sunny days seem sunnier. Gamma C is much like B, but a little less push in those brighter ranges, and a little push added at the low end to bring up the very darkest shadow detail. In other words, C, is very much like a cross between A and B, and personally preferable to either. Gamma D lifts the mid-tones only slightly. It is closest to Normal, but “brightens” the mid-range just slightly.

Basically I tend to favor D over Normal, but it’s not uncommon of me to change a gamma setting once I start watching. C is my choice when I want to make the image more dynamic looking. B will also do that but is often “over the top” and typically “distorts” the original too much for my taste. (when I’m being an image snob)

And of course, you can create your own, similar to any of these, with your own preferences, if you like to play.

JVC DLA-RS15 RGB Settings

These are the adjustments we made to Red, Green and Blue for the grayscale balance. Mike placed these settings into User 1. Calibration settings for User 1: Quick cal settings for User 2: Gamma on Normal, Color on –12 Gamma on D, Color on 0

Brightness Post Calibration

If you wish, you’ve got everything you need to copy our calibration efforts on your shiny new JVC DLA-RS15 projector. Keep in mind, there will be slight variations due to the lamp (and lamp performance will change over time). We calibrated with the lamp virtually brand new, as opposed to waiting a couple hundred hours, which is generally considered more ideal. There will be a continuing very slight shift in color over the life of the lamp. Bottom line: With these settings, this DLA-RS15 projector puts a really impressive image up on the screen.

JVC RS15 Projector Screen Recommendations

This section on projector screens for your JVC DLA-RS15, is essentially the same as the versions for the RS25 and RS35 projectors, due to their similarity. In reality, even the RS15 here, who’s blacks aren’t as good as the RS25/RS35 is close enough that the same “arguments” hold for all three projectors.

Great projectors tend to look great on any good screen. The trick with the RS15 is to match the screen to your room, and your viewing requirements.

For example, the RS15 does’nt have the best black levels around, but is so close to the best that you really don’t need to consider a high contrast gray screen, (like the Firehawk G3 I use in my main theater), unless it is to deal with some (side) ambient light. For those with a fully light controlled room, for example, the StudioTek 130 G3, or other moderate gain white surfaces should be an excellent match. Mind you, some of you with smaller screen sizes may want to lower overall black levels so might choose a high contrast gray surfaced projector screen. I had only minor issues with the black levels when switching to my Carada Brilliant White 106″ screen (gain 1.4), in terms of black levels.

The RS15 projector filling my 128″ screen has black levels only slightly noticeable on dark scenes, when looking at the letterbox area. Not bad at all. Personally, I like that, and probably favor a screen like my Firehawk over a tyical white surface. That said, a lot of that, is my personal preference. I’m willing to give up a little corner roll-off for those even blacker blacks.

Thanks to the RS15’s brightness in “best” mode, the RS15 has plenty of horsepower to handle the full 128″ diagonal size of my Firehawk G3.
