I am often in agreement with you on most things but I totally disagree with you on this position.
I swear this whole thread is like people are living in LaLaLand. I just can’t help but scratch my head at some of the things being said here.
You out of all people should understand that screen selection is just as important as projector selection. You wouldn’t pair a 5000ES with a 100” 2.4 gain screen and then say the projector is “defective” because it puts out too much light. That’s just nonsense. Nor is the RS4500 defective because it couldn’t even properly light up a 13’ wide negative gain AT screen.
Screen selection has ALWAYS been important and can absolutely effect the overall performance of the system. This will remain the case until we finally replace projectors with LED tiles or whatever else.
Personally I don’t know how anyone could watch a 2.4 gain screen. I guess it’s because they don’t know what a reference screen, like the ST100 looks like. The difference is night and day. I would not only consider that screen a compromise for SDR but I would also consider that screen a compromise with HDR, because of all the horrible side effects of a screen like that.
I get that many people are use to fairly dim units. Personally, I don’t understand how anyone can enjoy 14fL for SDR content. 20-25fL should be the absolute minimum target for Home Theater in my opinion. You are the one who pointed out we aren’t just trying to match the pitiful performance of “cinema projectors”
You have made multiple comments that 5000ES owner’s are either too lazy or incompetent to take detailed measurements on their projector. I don’t know why you keep repeating this. There has been plenty of measurements taken. I have taken plenty and I know Ken Whitcomb has as well, along with LJG (Lon Goldstein), and others.
Not only that, but when you said you couldn’t get a 5000ES for review, I personally offered to pay for one and have it shipped to you, so you could do a review on it. Unfortunately S&V declined the offer, and you didn’t have any interest in reviewing the unit independently at the time.
None of the 5000ES owners, at least the ones I know personally, are using dynamic dimming. They don’t want the side effects that come from gamma manipulations, light fluctuations, etc, that come from dynamic tricks. They all pretty much gained a 5x native Contrast Increase from 3-chip DLP, which was the only option prior, so we are satisfied with step up.
We would all welcome better units. We all want brighter and higher contrast units. We want closer to full rec2020. We want them cool and quiet. But we have to work with what we currently have available.
The JVC RS4500 had massive problems on release. It was one of the most disappointing units I had ever bought “Initially”. I was as loud as a 3-chip DLP, with a fraction of the light output. And for people who need a lot of light, the fact remains the native contrast of the JVC chips are 1/3 less than the native contrast of the Sony’s chip. Neither company has been able to make higher contrast native 4K chips.
The RS4500s “Dynamic Dimming” was completely unusable on initial release. It was always adjusting a frame or two to late or something and you would get a quick flash of light between scene changes or at the wrong time. Both units I had, have massive focus drift, and this still haven’t been resolved. I shouldn’t have to touch up the unit every couple days or each week. But the good news is things have improved. But there are still guys like Mark_H who still don’t use or like the dynamic manipulations of the image.
This is one reason I really like my RS600. I get a lot of native contrast and don’t have to use the dynamic iris. I can’t stand it on either of the JVC units, when things like Netflix menus are so dim, you can barely even see them and there is significant color shift. The Netflix white spinning wheel is suppose to be bright white and not a super dull/dim yellow.
Again, I don’t think the 885 is perfect. But I don’t think either of my 5000s are perfect. Nor do I think the RS4500 is perfect. But everyone who bought the 885 knew it didn’t have a manual or adjustable iris. And I still don’t believe one is ever coming to the 885.
I do fully believe they could work on the dynamic laser dimming and release future firmware updates. I wouldn’t solely base the “development” of this for the 885 off the 5000ES.
The 5000ES is built off a commercial chassis, and I don’t think there was ever a huge focus on this, as Sony is the only company to date to offer such high native contrast on such high brightness units. At least I don’t know of any other units that do 4000+ lumens at 15-17k:1 native Contrast.
I’m also not surprised to hear you went back to an E-shift JVC, as you were one of the few people who didn’t just say the RS4500 is perfect and the best at everything. You gave it both praise and critique. It also seemed like you were never completely happy with the step down in native contrast between the two units.
The 20% contrast loss between 0 power and 100 power on the 885 is just not that big of a deal, and not something anyone is going to notice. It would be nice if they could possibly dim the laser down “more” for those who have small high-gain screens, so they can target a lower fL if so desired.
But I think the best solution Sony can provide moving forward is giving some more “dimming range” on the laser, and then working on what is essentially a non-functioning dynamic dimming system. Both of these things could be addressed via firmware and I do believe Sony is likely to do so.
