JVC DLA-X70R Calibration and Settings

NOTE: We adjust the general controls and perform a grayscale calibration of the DLA-X70 projector. We do not do a full individual color CMS calibration. Note, this JVC X70 projector, unlike the lower cost JVCs, does have a full color management system. Still, we leave adjusting the individual colors for your calibrator. If you aren't into calibrating your DLA-X70R - either yourself (hobbyist), or hiring, then we strongly recommend you try plugging in our settings, and seeing if you like them better than the defaults.

Color Temperature

Lumen Output and Color Temp at 100 IRE (mid zoom):
Cinema	674 @ 7972
Film	643 @ 6897
Natural	813 @ 7562
Stage	832, switching to color temp 7000 yields 855 @ 8096
Animation	796 @ 9201
3D	781 @ 9631
THX	820 @ 7623
User 1-5	820 @ 7634

Essentially the User modes, and most of the others, are the same, but for some variation in which color temp is used.

Color Temp over IRE Range, Best mode (Film - Pre calibration):
30 IRE	6869
50 IRE	6869
80 IRE	6858
100 IRE	6897

Basic Settings

Tint = (0)	(0)	(0)	(0)	(0)	(0)	(0)	(0)	(0)
Color Temp =	(6500)	(Xenon2)	(Xenon1)	(7500)	(7500) 7000	(8000)	(8500)	(6500)
Gamma =	(Normal)	(A)	(Film)	(Normal)	(D)	(C)	(A 3D)	(Normal)

In addition to calibrating Red, Green and Blue for a correct grayscale balance (6500K), there are a number of other settings that come into play. Typically Contrast and Brightness (white balance and black balance), need to be done first. Color saturation and gamma also need adjustment.

Settings for measurements (default values are in parenthesis):

All other settings at default. Color Profiles are not in parenthesis but are the defaults.

Color Profiles: THX Cinema1 Film1 Video Stage Anime1 3D Video

Unlike the less expensive JVC projectors, the DLA-X70R has a THX mode. It also has a number of different Color Profiles that can be selected (in addition to the Modes), shown above.

Post Calibration Grayscale - User 1 "Best" mode

Average gamma= 2.19

Best Mode: Lumens at 100 IRE: 748 @ 6528K (mid zoom)

Brightest Mode: Lumens at 100 IRE: 855 (mid-zoom), 949 (wide angle)

Calibration settings for User 1:

Lumens at 100 IRE: 748

No "brightest mode" was "created" due to Stage (with Color Temp set for 7000), being only about 100 lumens brighter than a calibrated "Best". Short translation. Use either the calibrated mode, or when you want a little brighter, Stage, with color temp to 7000.

Mike's comments (same as on the Performance page): Grayscale calibrated very well, with an average Delta E of only 0.9 (same as the HD250). As Stage (the brightest mode) is only 12 lumens more than THX mode, there’s no need for a quick cal of a “bright” mode. Unfortunately, THX mode cannot be calibrated and has too much blue in the RGB balance. I see that the projector has an ISF designation, so presumably it could be calibrated in a service menu. Gamma was too low in any of the presets (Normal was the high with an average gamma of 1.96), so I used the custom gamma.

JVC changed things again with a variety of color profiles (ie: gamut). They all vary mostly by how much green is oversaturated. The THX and Standard color gamut (see CIE charts) are the best. One oddity which doesn’t really show up much in regular viewing is that if you put up a 100% blue screen in anything but THX color profile, it looks like a bluish magenta. Something’s not right there.

Here is the CIE chart showing the Gamut, that Mike mentions.
