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

JVC DLA-HD250 Basic Settings

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.

Our final settings (the default settings for Brightness, Contrast, Saturation and Tint are all 0, in all modes). Mike made adjustments to these, and the Color Temp settings for each of the seven modes:

Cinema 1 Cinema 2 Natural


Dynamic User
Contrast = (0) -1
Brightness = (0) 1
Color Sat. (-3)
Tint (-3)
Color Temp -6500
(High Bright)
Gamma (B)
(Normal) (C)

To get the very most out of the DLA-HD250, a calibration is recommended. You can try our settings, which should definitely improve on out of the box performance.

It seems to us, that going with the default settings for Cinema, will not get you the kind of color quality/accuracy, needed to rationalize a $3000 projector spend, for this projector. Once color has been "corrected" this projector is definitely worth its price.
