JVC DLA-RS1000/N5 & RS2000/NX7 Owners Thread

[JvcNativeLCOS]

Going to receiving my rs1000 soon, within a day or two, and had a quick question. 

Regarding cinema and the user 1-6 presets. For 3D, it’s recommended to either use 1 of these and set them for 6500k and rec709. I read in a review somewhere that the user presets are 100-150 lumens brighter than cinema in high lamp. 

Now to my question. Since I’m not calibrating my projector, can I still use the user presets?  Same settings regarding color and such as long as both are set for 6500k and rec709

Thanks guys. Never used the user presets before

Ok. Been reading manni’s setting for gamma. For sdr he recommends 2.4 or custom with a +3 correction value. Did that. 

Now for hdr, he recommends a gamma of 2.4. Where do I go to select gamma for hdr?  Is this no longer an option since firmware 3.10 as its dynamic now?

Gamma is used with SDR. Many use SDR2020 to display HDR material as it works very good with the external processors such as MadVR and the Lumagen Pro. If you are using the JVC for DTM select HDR10 and use the frame by frame tone mapping.

While waiting for the next batch of NX7's to arrive, I've decided to replace my screen.  Can you help me decide?  Currently I have a 108" diagonal 16x9 screen.  Throw Distance is 15-feet.  I'd like to project CIH on a 2.35:1 screen. My choices are a 133" or a 115" diagonal Draper screen.  The 115" is actually less square feet than my current 108".  The 133 is 25% more area than the 108. 
Here's my question: will I be able to achieve a sharp image is I use the Zoom method on the 133" screen.  A 25% increase in size seems like a lot, though I'm currently showing a nice bright image at 108" on my DLA-x790r.  My concern is loosing sharpness if I jump to 133".
Also, I'm considering 2 screen materials from Draper's TecVision line: an ALR grey with 0.9 gain, and an ALR grey with 1.3 gain.  Any thoughts or suggestions?  Thanks in advance!

I used the zoom method for years. Yes, the picture will be just as sharp on a 133" scope screen I currently have a 128" diagonal scope screen. As for those Draper materials, I'm not familiar with them.

Why a grey screen? I've always felt a grey screen was a crutch for a low-contrast DLP and not needed with a high-contrast projector.

Are you going to have the projector properly calibrated?

Good Question.  The NX7 has less native contrast than my current x790r.  I thought a grey screen, 0.9 gain, would help restore some of the lost contrast.  At one time I had a Stewart Firehawk (grey) screen and absolutely loved the "pop" it provided.  My thought was to try to get closer to the look of the Firehawk, but without the premium Stewart price.  Does this make sense or should I go for a white screen with 1.3 gain?  In some ways, choosing a screen is harder than choosing a projector.  Most of us keep our screen longer than our projector.   Yes, once the projector reaches 100+ hours, it will be calibrated by an ISF certified calibrator.  I still like using JVC Auto Calibration, but only for Gamma droop.

Grey screens don't give you more contrast if your room has light control. They may make blacks darker, but they also make whites and colors equally darker. I'd get a StudioTek 130 G4 - at least get samples. We can send you some if you want.

Thanks, Craig, in the past I've found sample size pieces of screen material are not of sufficient size to be terribly revealing (at least to me). The arguments against using Grey material is compelling.  I'm ordering the Draper counterpart of the Stewart 130 (TecVision XT1300X White).  One of my business Client's is an A/V retailer/ISF installer and Draper is the line they sell.  Whenever possible, I try to give business to my Clients, particularly when they are local (and deliver/install).
