Davo1972 Posted February 13, 2019 Posted February 13, 2019 (edited) Hey everyone! I've been fortunate to get one of the first of the new JVC 4K native projectors brought into Australia. Below is a link to my initial thoughts: For all new JVC 4K native projector owners please feel free to post your thoughts, experiences, information or hints and tips regarding the new JVC native 4K projectors! Edited February 13, 2019 by Davo1972 4
Davo1972 Posted February 14, 2019 Author Posted February 14, 2019 A couple of things. There have been reports on the AVS forums of "yellowing" of whites when using the DI. I can confirm that my projector does do this (noted when watching end credits on movies), but's it's easy to get rid of by disabling the dynamic iris. The yellowing doesn't appear to affect other content. Looks like a firmware issue. The DI doesn't have any blooming/pumping artifacts like the e-shift models are alleged to have, as far as I can tell. And I've attached a photo from Lucy below ("I feel everything"). This projector is sharp and detail is good 2
Michael391 Posted February 14, 2019 Posted February 14, 2019 Very nice Davo. Hope to have my N5 up and mounted this weekend so I can start setting up properly.But still enjoying it on the table behind the lounge on top of its box lol 2

It's the image it projects that matters mate But its always nicer when its mounted or installed properly The photo (taken with an iPhone X) of the hospital scene in Lucy that I posted looks a little soft to my eyes. The actual projected image is really sharp! With respect to the yellowing when using the dynamic iris I'll try and get the 1.20 firmware update and see if that improves things. Otherwise it might be a waiting game until JVC release a new firmware update to fix (if it's fixable in firmware). Michael have you noticed yellowing of whites when using the dynamic iris? For me it's mostly apparent when watching end credits in movies. I found if I bring up the projector's menu the end credits turn white immediately, and if I change to manual iris they stay white. Given that behaviour I do think it's something fixable in firmware. Looks like an issue with the gamma control related to the dynamic iris function.

Not seen the yellowing Dave at this point, maybe I dodged a bullet there. 1

Find some end credits on a film that you know are white (I used the credits on the Deadpool 2 4K Blu-ray last night), hit pause on your Blu-ray player and bring up the projector's menu. If you have the problem the credits should change from a slightly yellowish off-white to white. Turning off the dynamic iris will keep the credits white when you exit the projector's menu. I've seen on the AVS forum that the problem has been reported to JVC and there will be another firmware update being released in early March that should hopefully resolve the issue.
Michael391 Posted February 15, 2019 Posted February 15, 2019 Got it up but holy smoke it was heavy.......Currently running 1.18 firmware and needed 1 click red and blue to align.Colors are so bright and the blacks look so good. N7 must be bloody amazing.Plenty of content to look at this weekend and I’ll have a look at the yellow tint that Davo mentioned. 7
Michael391 Posted February 15, 2019 Posted February 15, 2019 Davo no yellow tint on mine that I could notice. 2

Thanks Michael, I'm extremely pleased you don't have the issue I don't think the yellow tint (only apparent when using the dynamic iris on my DLA-N7) is a sign my unit is defective, I think it's a problem in the firmware code for the operation of the dynamic iris. To be honest if I hadn't seen it reported on the AVS Forums I probably wouldn't have noticed it. Hopefully JVC can release a firmware update to fix it, but if they instead come back and say it's working as intended it's not a deal breaker for me. My DLA-N7 is awesome otherwise, the lens is sharp with only the very slightest softness at the very bottom of the screen (which is related to the geometry of my projector and screen setup rather than a lens issue), the Dynamic Iris is completely silent in operation, the picture it throws is incredible with excellent brightness, deeply saturated colours, deep blacks, and sharp detail, and the fan is near silent in low lamp, and still very low noise in high lamp (my old Sharp DLP was louder in high lamp and projected a much dimmer image than the DLA-N7 throws in low lamp/SDR with the iris clamped down to -7). I'm loving watching movies on the DLA-N7. For new movies it's better than going to a commercial cinema to see them, and for movies I've seen before it's like watching them again for the first time! 2
Michael391 Posted February 15, 2019 Posted February 15, 2019 Do anyone know if we are going to get the same deal as the Americans and Canadians and get a free globe like they are........ Would be nice.

Michael391 Posted February 17, 2019 Posted February 17, 2019 Hope they release a new firmware very soon. Takes almost 2 minutes to boot up which seems a little excessive. But still loving it. Certainly messing around with it, and can see the blooming on the end credits if i get a bit closer. 1

Michael391 Posted February 17, 2019 Posted February 17, 2019 Just wondering with other’s running the new projectors. When watching a 4K hdr Blu-ray are you finding low lamp is ample to run these movies. Projector is 4.1 mtrs to a 120” screen. 1.1 gain. 1
betty boop Posted February 17, 2019 Posted February 17, 2019 @Michael391 whether adequate ? Check output level achieving on screen if getting around 30fl on low lamp for HDR that’s great, if less and run out of iris then Might need to run on high lamp 1
Owen Posted February 18, 2019 Posted February 18, 2019 30fl (100nits) is STANDARD DYNAMIC RANGE. HDR is 300fl (1000nits) and up. As Michael391 has discovered we DON'T NEED stupidly high light output to produce a great picture. HDR is utter BS with projectors, unachievable and totaly unnecessary. Native contrast RULES not Lumens. 1 1
betty boop Posted February 18, 2019 Posted February 18, 2019 looks like some good feedback from manni over on abs, looks like posted more extensively in a 2019 calibration thread he has started, will check out when get a chance. seems he is :super happy" with the new rs2000/n7 saying in HDR it is best picture seen in his room and he is prior x series owner. Originally Posted by Manni01 ~ My unit might sit on the low side re gamut cover due to a very sligth undersaturation on red, as I would have expected a bit over 100% of P3 with the filter and around 90% of P3 without. This being said, especially in high lamp where the filter only cuts 10% of brightness to deliver 100% of P3 color volume (vs 85% without) and almost 20% more contrast (30K:1 vs 25K:1 without), my advice to use the filter if you can afford it stands, especially in high lamp, if my results are typical. Even in low lamp, I happily take the 20% cut in brightness to get 100% of P3 and almost 20% more native on/off. With good tonemapping, 120nits (around 40fL) is more than enough to get an amazing picture. This being said, saturations track very well with (BT2020 color profile) and without the filter (HDR color profile), so if one has to eek every ounce of brightness, using the HDR color profile remains a very valid choice and can be done without looking back or losing sleep over it Please could you confirm if your "25%" meant 25% *gain* from the brightness measured with the filter, using low lamp? This means only a 20% *cut* and would start to confirm this theory. Also, if that's the case, if you could report numbers in high lamp that would be great. Same for anyone who has reported filter measurements ( @Chad B , @Cine4Home ) If that's not the case, then I guess my theory is flawed I have posted very detailed brightness, contrast, calibration (including saturation and luminance linearity tracking, gamma/greyscale, and color volume for both rec-709 and P3), recommended settings and first impressions in the new calibration thread for the 2019 models. It's only a data point of one, but I couldn't be happier. I'll answer any questions you might have regarding these measurements there. Despite the slight step back in native contrast (from 40,000:1 with my rs500 to 30,000:1 native in my HDR calibration in low lamp iris fully open), the rs2000 throws the best picture I've seen in my cinema room. Sure, the black floor doesn't go as low as my rs500, but in every single other aspect, it's a significant improvement For those who wonder and want the tldnr: I'm super happy with my rs2000. If you don't hear much from me over the next couple of days, weeks and possibly months, it's because I'm enjoying the projector and watching all the movies I've saved in the last few months. Hopefully the next f/w update (expected in March) will solve a few niggles, especially with the DI that I preferred to switch off for now. But that won't stop me from enjoying the projector in the meantime. It was well worth the wait! 1
betty boop Posted February 18, 2019 Posted February 18, 2019 found manni's more extensive thoughts in the calibration thread (can only find the avs discuss version rather than actual avs, if someone finds do post a link). anyways below are overall impressions and conclusions of RS2000 as previous rs500 (JVCs x7000) owner. "Overall impressions: From every single aspect of picture performance (except native on/off and absolute black floor), this rs2000 is a very significant improvement. The rs500 was a very good projector already, especially with custom curves and then madVR, but it's no match for the rs2000, even with the loss of on/off, except on fade to black. When watching good 4K content from Lucy, or the imax sequences in MI, or about any of the films I listed above, the uptick is significant to very significant. The increased native resolution is clearly visible at 1 screen width. There is a lot more detail, and the picture is much calmer. This is especially visible on scenes where there are fine textures (sand in the opening sequence from Mad Max for example). e-shift does a great job on the older models, at least on my rs5000, but there is bit of added "noise", especially when the film has a strong film grain, such as Mad Max or the 35mm sequences of MI: Fall Out. There, the sky, the clouds, the skin shows with a lot less added noise. We get the film grain (which I like) and only the film grain. This is for me a very significant improvement, and it was one of the few issues with the rs500. That's gone! The drop in native contrast (from around 40,000:1 native on the rs5000 is this calibration to 30,000:1) isn't visible to me with most content, especially hHDR content, unless I'm watching star fields or a fade to black. There is a lot of contrast in the picture (I don't know if the ANSI contrast is increased or not, but it doesn't seem worse than on the rs500, that's for sure). For example, the scenes at the hotel in Lucy with the bad guys in dark suits and the very bright lights, or the opening sequence of John Wick 2, provide an amazing perceived contrast, and very deep, very inky black. Once we can use the DI, this gap should get even closer and improve the darker scenes. The black bars are not inky black of course, but they were not with the rs500 either. I use manual masking on my 16/9 screen, as I shift the picture to the top of the screen and I place a single mask at the bottom (I have two, one for 2.35, one for 2.40 A/R). This definitely helps increase perceived contrast, but I did all my testing without this masking and the black bars were not objectionable. Color looked fantastic, well saturated without excess, very natural. Again, a big uptick to my rs500, although I could only cover around 90% of P3 at 3,000 hours, so I couldn't compare with new. Shadow detail was excellent, even with brightness at -2 for max contrast. It was improved further at -1, with a very minimal hit to black floor/contrast. After watching both, I prefer -2. It's really the first time for me that I had this "looking through a window" feeling that owners of projectors that I can't justify buying keep mentioning. In many cases, breathtaking. In fact, I quickly had to mute the sound when watching the clips, because watching these films, that I know very well, on this projector, made me want to watch them all over again. My main issue with the rs2000 is the DI, which I use only on Auto2. It does produce less pumping (for example with opening/end credits), but there are two main problems with it: 1) There are still some gamma artifacts in tricky situations, such as the underground scenes in MI:Fall Out at around 05:00:57. The DI makes a real mess of the car headlights, turning them into big blotches, instead of the well-delineated outlines that you get without the DI. 2) There is a strong yellow tint caused by the DI when the picture comes out of black. This is very visible for example at the beginning of Mad Max Fury Road, after the Mad Max Logo when we cut to Furiosa's neck. I'm sure the second issue is a bug that will be fixed by JVC (they are aware and apparently a new f/w should land next month). For the first issue, if they can't resolve situations like the MI:Fallout, I would like to see an Auto 3 mode that would only have an effect on fade to black, be faster than auto 2 and would have zero gamma manipulation whatsoever. The current Auto 2 is much slower than on the rs500 (it takes around 4 seconds for it to close fully) and it doesn't close down as much, which means that the black floor remains quite high. For example, with the rs500, I could reach up to 500,000:1 dynamic contrast and more (calibrated to D65), but on the rs2000 the absolute maximum dynamic contrast I could measure is 235,000:1 in high bright (uncalibrated). As with former models, there is no difference between auto1 and auto2 regarding contrast measurements, auto1 only has a more aggressive gamma manipulation. The ceiling is set with the manual iris, so doesn't change much between manual, auto1 and auto2. Auto only changes the black floor. Conclusion I did all the measurements first because apart from the need to have a calibrated picture, I know that if I start to watch content with a new projector (provided it's a good one!) I won't ever take the time to measure. This is exactly what happened with the rs2000! I have kept my rs500 because I was thinking I could run a dual projector setup, with the rs500 for SDR rec-709 content and the rs2000 for 4K HDR content. Not going to happen. I'm going to keep the rs500 as a backup projector, possibly to tie me over in between projectors, but I don't plan to use it, even with SDR content. In low lamp, with the iris closed to -12 to get 60nits, and especially when we'll be able to use the dynamic iris on the rs2000, there is really no need to keep the rs500 active. The rs2000 throws by far the best PQ I've seen in my cinema room. It's very film-like, has great contrast and looks significantly better than our local cinema (proving that size isn't everything). So the rs500 going in semi-retirement, and I'm going to enjoy my rs2000 a lot. If you don't hear from me for a while, don't worry, that's because I'm watching movies!" 1
