In my reply above I quoted
and responded to his concerns about the Optoma HD27E as maybe a better placeholder than the BenQ HT2050A and he was posting with regards to
who was sold on the BenQ HT3550 This was in posts 227 & 228. Tony’s concerns were really where I was directing the comments about the HT3550 loss in brightness when displaying true 4k HDR in all its glory.
So the discussion was started here as he was looking for pros and cons between the HT2050A and the HT3550, seeing as how he is going to be very limited as to how much true 4k HDR he will even be viewing for a relatively long period of time. He streams 1080 he watches BD he now owns and like me he rents BD where we both wonder how long it will be before UHD BD will if ever be in the rental machines. He is hearing correctly I think that the larger DMD dark chip 3 in the HT2050A has some contrast and black level benefits over the HT3550 that the active iris may help improve some.
I was trying to just point out that my understanding was with the HT3550 there was also a brightness hit when doing full on 4k HDR with the DCI-P3 color space, and his screen size may factor in to the equation. If he is going to play 4k HDR media and needs the extra brightness forcing the filter setting that switches to Rec.709 color space it may move the needle a bit more in his comparison.
I guess his real question and maybe he should start a new thread just on this topic is what visual advantages will be seen playing 1080p or lesser media on the BenQ HT3550 compared to the HT2050A. I haven’t seen the HT3550 well none of have for that matter. I assume having the 1080p up-scaled to 4k is an improvement. Will the BenQ’s excellent PRO tone mapping come into play when viewing BD Rec.709 content or will the color, contrast, tone mapping etc be the same/better/worst, between the two projectors?
I’m in about the same boat as Tony. My physical media purchases over the last year have really slowed down. I maybe bought 6 BD’s over the last year. They really have to be something I want to watch fairly often. The last BD I bought I saw came as a combo pack BD/UHD BD and the cost wasn’t much different. I thought here is a way to future proof my collection without diving in to trying to replace it all again. So I own just one piece of UHD media my guess is a year from now I might have 3-4 more. So whatever I do stick with my 1080p dark chip 3 or upgrade to 4k 99% of my viewing will be 1080p or less.
Thanks for the links. They like most I have read deal with flat panel displays where they hit 1000-5000 nits and such. I do understand that the classic gamut charts we see are 2D and real color space is a harder to visualize 3D space where the third direction is luminance. A lot of the expanded gamut is in color luminance and that is getting a bit off topic for this thread or for projectors in general for that matter.
