As has always been the case with JVC's entry level home theater projectors JVC DLA-HD250 home theater projector lacks the full CMS - color management system - found on their over $5000 JVC's. This means that you can calibrate the standard items - brightness, contrast, color saturation, and also do a grayscale balance, to get the color temperature to 6500K.
The JVC DLA-HD250 also lacks the rather excellently pre-calibrated THX mode found on the JVC X7 and X9, RS50 and RS60. Those THX modes are excellent whether on a JVC projector or one of several other brands that provide them. Runco was first, now JVC, Epson and Optoma, others, mostly on their higher end models. While you can improve on a THX mode with an individual calibration, it would be slight. On the other hand, this HD250 while not bad out of the box, definitely improves noticeably with calibration, even without a Color Management System.
JVC DLA-HD250 Color Temperature
All of the JVC presets offer a bit cool white, with white (100 IRE) at 7142K or higher, instead of our "optimal" 6500K.
That said, the JVC HD250's color temperature gets warmer, as we go down the grayscale, until it's actually very warm by 30 IRE.
These are the measurements, taken "right out of the box."
Color Temp over IRE Range, Best mode (Pre calibration):
30 IRE 7123
50 IRE 7054
80 IRE 7110
100 IRE 6934
For your convenience, these were the starting measurements:
Lumen Output and Color Temp at 100 IRE (mid zoom):
Cinema 1= 801 @ 6934
Cinema 2= 743 @ 5942
Natural= 803 @ 6948
Stage= 865 @ 8036
Dynamic= 934 @ 9064
User 1, 2 or 3= 803 @ 6955
JVC DLA-HD250 Post Calibration Grayscale
Here's a look at the results of Mike's calibration (saved to User 1):
Color Temp over IRE Range (Post calibration):
20 IRE 6636
30 IRE 6667
40 IRE 6593
50 IRE 6517
60 IRE 6592
70 IRE 6561
80 IRE 6565
90 IRE 6460
100 IRE 6402
Average gamma= 2.23
Mike's comments on the HD250 calibration: Grayscale calibrated quite well, with an average Delta E of only 1.1. The RGB balance was actually better than the RS15 we did earlier this year. It's unfortunate that the custom color temp starting point is so far off from 6500K (it's something more like 8000K) at higher IREs. This requires big reductions in Green and Blue Gain to get things balanced. The color gamut (see the CIE chart) is the usual JVC expanded gamut and without a CMS like the more expensive models have, all you can do is turn down the Color control to reduce the "sunburned" look in skin tones. Grass and other green items can still be almost a "neon" green however.
Art's comments: regarding sunburned and neon, we're talking "first degree burns here, not 2nd or 3rd... As to neon, Mike's getting colorful! "almost neon" naw. rich, oversaturated yes, but really dayglow or close, no... Even on my images which as a group are oversaturated, none of the greens -even grass, is close to "neon"... And all of this typical of JVC's lowest cost projectors. All that said, it looks real good! -art
