My comment was in relation to what was said.....”calibration on an LK990”. From our long explanation and discussion of how the XPR RGBY laser phosphor Brilliant Color DLPs differ from normal 3 panel technologies like LCD, LCoS, SXRD, etc. it was made clear to me and I tried to pass along to you that you just couldn’t use typical calibration techniques and technologies to see how these perform perceptually and subjectively. This is based on how the whole system is engineered to give the same look on the screen, even if the numbers like color lumen/volume don’t appear to corroborate that visual when measured.
This is what I tried to convey and was explained to me anyway by the Optoma Product Manager through their engineers and the Vivitek Engineer who designs theirs. It is a “trickery “ they use a design into it so to speak when you combine all these attributes of Brilliant Color, dual wheel RGBY laser phosphor, XPR, HDR, BT2020, etc.
This is what was explained to me, I did what they said and that advice has worked extremely well for me and I do not see any of the issues I hear reported from those that don’t take that advice. If you want to know more or prove or disprove this, ask the ones that enlightened me after my UHZ65 fiasco (much the same as what you’re saying here about the LKs), the Product managers and engineers who designed/implemented this technology.
I believe Maestrosc tried my settings and said they looked very good but he just is too sensitive to RBE to keep the LK990, which is unfortunate. Maybe he can comment on the image taking RBE out of the equation?
If it werent for the RBE, I would 100% be ecstatic about the projector and more than happy with it. Its incredibly sharp and bright. Even the lowest/darkest content I could find I thought the performance of the LK was way more than acceptable. I feel like sitting next to a projector that specializes in these scenes, it would probably look comparitively worse? But sitting in a dark room, by itself, the image I saw on even the darkest of scenes, I cant imagine anyone (not on this forum, or who personally owns a darker projector. I mean average movie-goer, friends, family, people who I would invite over to watch a movie - I am just saying, for the average person, who isnt comparing to a referenced image side by side, I dont think they would call the blacks gray or say that everything looked grayed or washed out) complaining and saying that everything "looked gray".
I will say, that I preferred the normal or eco over smart eco. The Smart eco there were a couple times where it couldnt decide whether to amp the brightness up or down, and it was more distracting that you saw it change midway through the scene, rather than if it had amped it up previously or not.
1000% if it wasnt for the RBE, I would be installing the LK990 this weekend. 99% of the time everything looks great, but then RBE from either a chrome or gold metallic hits me and its distracting enough to me that it pulls me out. I brought my brother over to look at the 990's image, and he said he had no problems with it and could only force himself to see the RBE, but it was definitely not enough to distract him or if he was me, to send it back. So its again, RBE is just a personal thing that affects everyone differently.
But the reality is, that I am now looking at spending 30,000 for a 4 year old projector, the only difference being it wont have RBE. I know the image quality simply isnt capable of improving 5-fold, though the cost is increasing x5.
