JVC DLA-X70R Performance 2

Post-Calibration Brightness

Art’s NOTE: The JVC X70 R doesn’t exhibit the slight blue shift in the very dark regions that the RS45 had. 
                                                
Mike’s NOTES: 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.

The Calibration page provides the settings we used. That includes basic settings as well as gain and offset.

Sharpness

The JVC DLA-X70R starts out “typically sharp” for a 3 chip or 3 panel projector. All else being equal, single chip DLP projectors have a sharpness advantage as they don’t have to align and converge separate Red, Green, and Blue light.

But this is JVC with their “4K” e-shift technology, which I discussed on the first page of this review. While I don’t buy into their marketing of 4K, e-shift does bring things to the party.

For most viewing, the DLA-X70 seems to be at least as sharp as any other 3 panel/3chip type projector I’ve seen, at least if we exclude some many times the price 3 chip DLP projectors (with optics that probably sell for more than this projector). The Epson 5010 I have here for reference for black levels, seems to be very sharp for a 3LCD projector, and at no point, did the JVC not seem every bit as sharp. Overall, I’d say the JVC is a tad sharper than the Epson. It will take a good DLP to look visibly sharper/crisper.
