Over the last two years I have been extremely pleased with the beautiful, sharp, film-like images with great native contrast from my JVC projectors; I owned a pre-order RS4910 and then moved to a pre-order RS500. I watch on a modest 100-inch wide 2.35 screen and sit about 1x screen width away; the brightness of the RS4910 was good and the RS500 has been very impressive with the bright punchy image (even with the manual iris at -14/-13).
At my seating distance I found that the RS4910 needed CMD on low to improve the motion on many sources (albeit it smoothed a little too much) and now I have enjoyed the new Blur Reduction on the RS500 which seems to have taken the edge off; but I still found it disappointing that the RS500 CMD frame interpolation still has the vertical banding artifacts which are often visible in low-/mid-APL content -- thus making CMD still useless to me as the banding is so jarring that it pulls me out of the content.
The pink JVC elephant in the room for me is the flicker in high-APL image elements
. I'm not referring to lamp flicker (AFAIK
), nor am I referring to dynamic iris gamma flicker. The flicker is (also) present on high lamp, with dynamic iris disabled, all processing disabled (MPC, CMD, Clear Black), on both 24 & 60Hz content. I have used multiple sources, multiple HDMI cables, isolated the power using a UPS running off battery. The flicker is visible (although much less so) on the blue screen when no HDMI input is available. Not only can I see the flicker, my wife can see it, as can several friends, so it is clearly not only an individual sensitivity issue -- although it has only bothered me. My hypothesis here is that it is a combination of the low panel refresh rate (96Hz for 24Hz content and 120Hz for 60Hz content) and the high contrast nature of the panels; see this document of mine for a quantitive evaluation

The flicker is not noticeable to me in all content, particularly when I'm not looking for it -- the flicker is however quite noticeable when the image is of a fairly static scene (for example some of the nice bright desert panoramas in Lawrence of Arabia, but is also visible in almost any paused image with high APL content like overexposed windows). It is incredibly noticeable on the high-APL calibration image of the AVS709 disc for another example. The real problem is that not only is it often noticeable and jarring but that sometimes it is so strong that I feel physically affected by it -- like looking into a muted strobe light
So I sold my RS4910 last fall because I felt the flicker must be a fault of my unit (despite the fact Mendtronix was able to discern the flicker but they were told by JVC that it is normal). Note I did disclose the flicker to the RS4910’s buyer, but I haven't heard back that it was bothersome to them. As I didn’t have a local dealer to demo other JVC unit samples to look for the flicker, I decided that I would give JVC another chance given the otherwise excellent image and so I pre-ordered the RS500.
This week I watched the new National Lampoon Vacation on the RS500 with the wife and barely noticed any flicker; in fact I could barely see it when I looked for it -- except when I paused the movie for an intermission, but even then it was still only modestly obvious. However, I also watched an episode of Game of Thrones the same night and the flicker was quite distracting in the bright snowy scenes -- with no need to pause or intentionally look for it. Finally, I just received a replacement RS500 (due to an unrelated defect in the original RS500) but only fired it up last night for less than an hour because the same flicker was still present.
Due to the (occasional) physical discomfort, I will be returning the JVC RS500. I don’t see any similar kind of flicker on my Mitsubishi HC7900DW DLP. I recently stopped by a Sony dealer and did not see the flicker (on the same content) on either a VW600ES or a HW40ES -- presumably due to the 240Hz panels and/or the lower native contrast.
My current plan is to get an Epson LS10000
. Between the stable laser light source and (up to) 480Hz panels, it seems to be the best option w.r.t. flicker and despite some comments here to the contrary seems to be the second best image to the JVC for the price range. The intent is for the projector to be flipped in 1-3 years for a 4K upgrade of some kind.
I suppose my only hesitation is UHD Blu-ray compatibility, specifically 10-bit and DCI-P3 color. Without HDR and REC2020 container support, it is still an open question as I understand whether I will be able to get DCI-P3 color in a P3 container from the initial (or any) UHD Blu-ray player to fully utilize the LS10k. Given this, I plan to suffer with my low contrast DLP a while until the new players are available in a month, maybe then some questions will be answered.
Any opinions on the flicker and on my choice as LS10000 as the next best option?
