The last couple sentences are key to what is seen. This goes to what I’ve been saying, that the black in the video is definitely darker than what is seen in things like a 0 IRE pattern, the black bars on 2.35:1, the pond of mirror edges, etc. If you blank those out or ignore them and ONLY concentrate on the active video, it’s absolutely stunning!!! This is why I think an anamorphic lens is best to get those bars out of the viewable area so they don’t destroy your perception of the black reality!
It needs some actual measurements (which I haven't managed to find either); this is all measurable at this level. The only difference in perception of black within scenes would be down to differences in ANSI contrast / ADL contrast for peak white matched, or higher peak white / ambient light biasing the eye differently.
It is hard to see from this quote what he's saying - if it is >measurably< darker on screen, or if his assumption is the projector is that the projector outputting a darker laser level because when outputting the pluge test the power consumption is lower than with the 0IRE screen. There are other reasons the power consumption may vary, so the AC power draw would get you into the vicinity of understanding. To be sure about the laser operation you'd need to be watching the drive for the laser module directly.
I really wish someone would come out with some detailed numbers (I thought I found another of 12GAUGE's posts the other day, but still I couldn't see any actual detail numbers on what was going on. Maybe it made sense to him as he was doing it, but from the post I couldn't really gather anything. Tables of data are much better than sentences). ADL contrast charts would be a start, detailing what the peak white and black measured is for each ADL chart. Probably needs to use the lower level charts that
did, too (between 0 and 1%, and for DI/DD testing). Example scenes picked out which show off the projector strengths and weakness would be good too.
It's also really hard to get a feel for how folk have these units set up for things like peak white in SDR, room layout and lighting, etc as there are so few of them. You can create all kinds of interesting optical effects if ambient light is introduced into a room to bias the eye. This can and does make the black level appear much darker in mixed scenes as the eye gets biased away from being so open. As an example, in my black hole cinema the other day watching Teen Titans the Movie - you could make the black look blacker in mixed scenes by leaving the lights on and door open. If I crank up the lamp mode it starts to >look< positively OLED'esque in those bright scenes set up like this. But any dark scenes look bad with the lights on and door open in this way. Light cannons in rooms which already have poor black floors and ambient light will undoubtedly look better in those rooms than darker projectors with better blacks, once your eye is already biased away from black.
I'm not doubting you in saying it looks great to you, but as yet I can't see any useful information about why this is, and without that it is very hard to make any sort of judgement as to whether it might look good in a given room in a given use. These are not stocked projectors in most places, and so in many cases (like listed in one of the threads) you're already putting yourself in a bit of a "position" in asking some dealer to get one in to show you, and that show you is probably not going to be in a representative room.
In my case I'm not interested in the laser unit as I know full well the RBE will do me in, but the 8060 LED is in the same situation - I know already unless field reports make it out to be the 2nd coming of the Messiah it's not going to be on demo almost anywhere. Ironically in the UK the best option is probably to buy it mail order as you have 14 day right of return under distance selling regulations. However some retailers try and shirk their responsibilities in this respect which makes even that not straightforward.
