JVC LX-NZ3 4K Laser DLP Projector Review – Advanced Calibration

JVC LX-NZ3 4K Laser DLP Projector Review – Advanced Calibration: CMS Calibration, Calibration Charts

CMS Settings for Best SDR Mode calibration- Cinema Mode

Each picture mode offered independent CMS adjustments. In fact, the Natural and Cinema modes come with their CMS settings preadjusted from the factory.

Once the projector White Balance was fine-tuned, the CMS tracking was decent out of the box. Prior to CMS calibration, the Natural Picture mode (which I chose for SDR calibration), the color and CMS performance were good with just blue and magenta color points being notably off their targets.

RGBCMY Hue Gain Saturation
Red 172 196 202
Green 202 176 168
Blue 159 146 187
Cyan 126 184 195
Magenta 246 180 164
Yellow 140 185 176

During CMS adjustment, I had to sacrifice achieving the widest color gamut in order to reproduce more accurate color at lower saturations. Increasing Color Enhancement setting under the MoviePro menu increased maximum color gamut but also results in overly saturated lower color tones.  With Color Enhancement set to 0, after SDR CMS calibration, most colors below 80% saturation had a DeltaE below 2.

CMS Settings for Best HDR Calibration – HDR Mode

In the best 4K/HDR Mode, pre-calibration CMS measurements showed similar tracking errors to those found in SDR prior to calibration. Just like with the SDR mode, CMS tracked better after white balance was calibrated.

Since the JVC LX-NZ3 doesn’t have the color filter found on more expensive home theater projectors, it can’t reproduce 100% of DCI-P3. The JVC LX-NZ3 color gamut measured at 75.67% of DCI-P3 and 57% of BT.2020.

RGBCMY Hue Gain Saturation
Red 167 286 225
Green 274 174 256
Blue 117 115 251
Cyan 138 180 342
Magenta 334 175 240
Yellow 107 224 169

To maximize the LX-NZ3’s overall color gamut and increase color saturation, when viewing HDR, I returned the Color Enhancement setting to its default of 12.

Using the CMS adjustments, I could only improve the lower color tones, so I focused on below 50% saturation. I was able to achieve a DeltaE of less than 2 for all the colors at 50% saturation except for green.

Overall, the DCI-P3 color performance could have been better but after calibration, the JVC LX-NZ3 still delivered a good HDR picture.
