HD/SDR

Full-on/full-off contrast ratio (SDR): unmeasurable

These measurements and charts were produced using Portrait Display's Calman software, together with X-Rite i1Pro 3 and Klein K-10A color meters and a Murideo test-pattern generator. The measurements were taken on a 96-inch-wide, 1.3-gain Stewart Filmscreen StudioTek 130 screen. 

The standard dynamic range (SDR) peak white reading for this measurement (with the projector's iris on manual and wide open) was 27.6 ft-L (94.7 nits). The black level was 0.000 ft-L. These numbers were read from the Stewart screen using the Klein meter. While the black level in SDR was barely visible to the naked eye in a totally dark environment on a full black screen, it was unmeasurable with the Klein meter.

The charts shown here are for SDR. Before calibration in the SDR Cinema Picture Mode, with some minor adjustments but no color calibration, grayscale Delta E figures ranged from a minimum of 1.15 at 100% to a maximum of 3.83 at 40%. After calibration with the Color Temp controls, the minimum and maximum grayscale Delta E figures were 0.7 at 80% and 1.6 at 20%, respectively. The color Delta E figures were all so low out of the box (a low of 0.13 for yellow and a high of 1.46 for cyan) that no color-management calibration was applied with the Color Profile controls.

The results of a saturation test, as color saturation increased by 20% steps, were good, though slightly undersaturated at less than peak output in red, magenta, and blue. A color checker test, which checks for the accuracy of a wide range of real world colors, was satisfactory but not exceptional, with an average Delta E of 3.4 and a maximum Delta E of 5.3.

The JVC passed the 3:2 HD, MA HD (motion adaptive HD), and 2:2 pulldown in our HD/SDR video tests. It won't accept a native 480i input; you have to upconvert older material such as DVDs externally — most Blu-ray players can do this. The RS1100 also passed both luma and chroma resolution tests.

(Delta E is a figure of merit indicating how closely the result matches the target value. Delta E figures below 3 — some experts allow for 4 — are generally considered visually indistinguishable from ideal.)

HD/HDR

Full-on/full-off contrast ratio (HDR): 19,797:1

Our objective results when calibrating the JVC using Calman calibration software were poor. JVC's recommendations involved the use of special JVC calibration software that we didn't have — software that, in any event we were informed (independent of JVC) isn't compatible with our color meters. I soldiered on using JVC's recommendations for setting brightness and contrast, but proceeded from that point using Calman. The results were still clearly unusable.

At that point, I determined that the subjective settings I had used early on for HDR were my best option. The results with these settings were excellent, as described in the main text of the review. (These settings will appear in the online posting of the review on soundandvision.com.) If you choose to have the JVC calibrated by an Imaging Science Foundation (ISF)- or THX-trained technician — something we certainly recommend — make sure you put at least 200 hours on the lamp before calibration. (For most of the results in this review, subjective and objective, the lamp hours exceeded 200).

This largely subjective setup process limited the objective HDR measurements available to us.  As measured off the screen using a Konica Minolta LS-100 luminance meter, the peak luminance was 136.6 nits and the black level 0.0069 nits, resulting in the full on/full off contrast ratio shown above. The peak luminance didn't vary with window size (unlike a flat-panel TV, the output of a projection lamp isn't affected by the size of the white window). The JVC covered 70.1% of the BT.2020 color space and 93.6% of P3. Virtually all consumer HDR source material uses P3.

7K? This week I can buy a Sony 85 inch 4K TV for 2K. That will blow this away. Okay, not a 120 inch screen which in my opinion is where you need to be for the theater experience, but for less than a third the price, close enough. An 85 inch screen turns any unused bedroom into a theater room. This requires a dedicated huge blackened space. i have that, have had that the 22 years, and I love it, but your Average Joe? projectors, except for the crazy expensive fine glassed lensed on a titanic screen for the 1%, are dead in the water. Just saying. JVC needs to marked this at a third the price, and even then, it is going to be a hard sell.

Would you go with the new line of native 4k projectors or stick with pixel shifting. I have the 790R and its a great PJ, the blacks are super deep which I love and it sits on a 126 inch screen, no 85 inch TV can compare, true you can go OLED or Mini LED for 83/85 inch respectively(If your sitting less then 10ft away), but pic quality will suffer for any TV at $2k. You want a TV that shines, go OLED or Sony MiniLED. All other TVs will suffer off axis viewing and substantial blooming IMHO. Most people who purchase these products are enthusiasts and with the steaming boom, more and more people are getting into this market then ever. You wont see PJs going away until 100 inch plus TVs become available for under 7-8k.....still some time left......

good question..i have the X950R..native contrast its insane, almost 150.000!
rs1100 has just 40.000

Should we remain with pixel shifting, or should we go with the new range of native 4K projectors? It's true that you can get an OLED or a Mini LED for an 83 or 85 inch TV (if you're sitting less than 10 feet away from the screen), but the picture quality will suffer for any TV that costs more than $2,000 regardless of the technology. I have the 790R, and it's a great PJ. The blacks are extremely deep, which I love, and it sits on a 126-inch screen 5 letter words.

Theater Optimizer combined with Frame Adapt HDR results in great-looking HDR10 content while eliminating the hassle of having to constantly make manual Brightness and Contrast adjustments from bright to dark scenes or from movie to movie. The RS1100 also supports Hybrid Log-Gamma Candy Crush (HLG) to ensure that users are ready for live future HDR broadcasts.

If you are opting for an Escorts in Aerocity from an escort agency again the aboriginal affair you should attending for if the aggregation is registered or not. There are assertive laws in India to attainable an escort agency, and if a aggregation does not chase those laws, again the escort bureau won’t get registered.

With the RS1100 having a limited three-year warranty, Quick Draw I think this is a good product to try
