The way I read a couple of recent posts that appears to be the case - and rather considerable, IMHO.
But first things, first. On behalf of Kraine I wouldn't discount the possibility that the quoted Chinese Xiaomi UST projectors perform dynamic laser dimming out-of-the-box, mistaken as "native" contrast, especially since the "dynamic mode" didn't yield a noticably better contrast.
It has been suggested that I missed tons of discussions concerning DLP laser which is correct. Given the limited lens shift range of the Optoma UHZ 65 and the extra cost of laser, I wasn't interested at first.
there is no devoted thread here at the AVS (or elsewhere) that discusses the apparently crucial difference between dynamic bulb dimming and dynamic laser dimming.
Instead we have this thread that correctly emphasizes how much native DMD contrast has deteriorated in the past years, but just now (?) also talks about technical evolutions to overcome this particular problem thanks to laser technology.
Why should I care about native DMD contrast when dynamic laser operation in my everyday use will yield better contrast levels and no disturbing operation hickups?
Do I care that the 4K DLP images are the result of XPR pixel shifting? If the objective result gets very close to the native 4K of other projector manufacturers I'd say no.
We might just as well discuss what a horrible, cheating technology DLP is - projection images aren't created simultaneously but sequentially.
