With all due respect Javs (and Kris), and I mean that wholeheartedly. I just don’t understand the tech involved totally in what these RGBY laser phosphor projectors are doing! I can’t send you any real different numbers than you’ve already posted and that’s the main reasons why I haven’t a lot, other than when I’ve tamed some of the misunderstood issues.
I’ve tried to hint at this numerous times and it’s just glossed over. When I first got a UHZ65 I was absolutely dumbfounded and baffled at the calibration process and measurements. It drove me insane and I trashed the projector just as you guys are doing now with the LKs. It wasn’t until I spoke with the Lead Product Manager at Optoma (who consulted his engineers) and a lead engineer designing XPR DLPs at Vivitek that I got a better grasp on at least how to handle, coax, tweak, what to ignore and what to concentrate on and how to massage these type of DLPs, that I figured out how to get them to perform at their best potential.
I went in circles for many hours scratching my head as you guys did so I totally understand this. I though the UHZ65 was garbage, just look at the thread from back then!
I really think it’s just them not sharing details of how these are engineered to work and produce their image between XPR, RGBY laser Phosphor, Color Enhancer and Brilliant Color.
I remembered we had a discussion about 1.5 years ago regarding the LK970’s clone, the Acer 7860 so I looked it up and Darinp had brought up what is the most likely scenario and cause, being similar to RGBW OLED, here (then a great discussion ensued):
There have been other discussions regarding this that we had already been over but you guys seem to be late to the party so maybe weren’t privy to them, idk.
Here is another I stumbled on which could have relevance here too, from
re: the OLEDs:
I REALLY just think it’s due to a strange and unique technology to get to the same end result “subjectively” (using a technology we don’t fully understand yet, but the engineers do!) when using XPR, RGBY laser phosphor and Brilliant Color for HDR. I recall SPECIFICALLY the Optoma Manager telling me I MUST use Brilliant Color for HDR and to ignore the whacky lumen measurements because they’ll never be right and if you force them it’ll make things worse based on how the technology works. I saw this first hand when I tried to go to extremes on the LK970, with the banding and solarization amongst other things. He said they all worked in conjunction to make it all be subjectively correct on screen. When I pressed them for details they wouldn’t share, so I just can’t tell you why or show you the data you’re looking for, because I get the same thing ON PAPER, but that’s not what I’m watching. I’m watching awesome HDR movies with awesome low APL and detail out the wazoo, not spreadsheets and calibration charts when it comes to these!
Get mad at me all you want, but all I want is for you to listen to what I’m saying and what I was told. That’s all I know and truth be told, the advice they gave me works wonderfully and apparently, based on what you’re reporting, yours (and mine with the UHZ65 initially) doesn’t. Sorry if that offends, but it is what it is.
I don’t really understand it all any more than you guys do yet, but I followed what they said and am more than happy with the results. People will see the truth soon enough when I am back in PA. Until then I will not argue with you anymore other than to say I do not agree with the assessments you and Kris report........at all!
