That content plays well to what's always been DLP's strengths. The Grand Tour would look fantastic on something like my Planar 8150 but 2-5x as bright, and I could definitely understand giving up contrast for that.
For me though, the vast majority of the 4K HDR I have and have, have access to, and actually watch is content that has lots of very dark content, lots of sci-fi/action movies. Those fall apart for me if black isn't black. And while I understand that brightness biases our eyes to improve apparent contrast, but I'm still skeptical that even 2000:1 native (with no DI) at 5000 Lumens isn't going to have a terrible black level in something like the Ministry of Magic scenes in Harry Potter. I mean you're looking at a black level that's at least 30x higher than my Planar's and I already don't find that acceptable. Heck, I'm still skeptical I'd find an RS4500 acceptable, but at least that has a very good DI algorithm to aid it, and 5-10x the native contrast of these DLPs.
I'm not saying your wrong, I'm just trying to calibrate your report/thoughts/opinion to my own experiences. If we watch dramatically different content, as it seems we do, then that's a key factor for me to take into consideration. What I take away from your comments is that for bright, punchy HDR content, these bright laser pumped DLPs throw a great image, and for that type of content, the black level sacrifice isn't too bad.
I agree but what you're not taking into account is how different these are when using the laser phosphor light source and the dual phosphor and color wheels than standard lamps with single color wheels. I am saying that people keep trying to compare these laser models to the old DLPs and the cheap under $2000 XPR DLPs that use lamps still. That was my point.

Have you managed to watch fast action sports on the LK970, does it have the usual judder without a CFI mechanism ?
Any more information on its dynamic contrast/ laser dimming approach ?
I find that question very hard to answer on which one I would choose because there are such positives and negatives with each one. I would say it more is down to what content you watch and whether it is mixed content or just movies. If it's just movies then I would use a Sony or JVC but if you also like to watch sports and TV and other SDR content like that then as I said again the positives far outweigh the negatives and yes I do mean even the black levels. I really do think that the Vivitek DK8500Z will balance this the best since it has native HDR support and laser dynamic dimming as well as 3-D.
I've watched some sports like rewatching the Super Bowl and my Eagles spanking some Brady and it was one of the most enjoyable experiences I've had, but for the content and the quality of the image.
I can't stand CFI.

Have you yet had a chance to take a measurement of the black level on the LK970?
... measured the contrast?
No because BenQ absolutely sucks when it comes to responding to inquiries.
I think what I am seeing on the LK970 is the "feature" called "Constant Brightness" on the Viviteks, described here on page 40 of the DK8500Z manual:
I've taken some measurements but I am not posting anything because it is still a work in progress.

Well I think a lot of the reason is the content one watches and the fact that they have different views, feelings, thoughts and needs in this world than yours! If we all thought and felt the same, this world would really be boring and suck, don't you think?
