Ultra-Accurate 4K HDR BlueCore Laser Projection for Enjoying Superb Entertainment Content "
So how is that not spec'ed for HDR or "doesn't do" HDR?? What does "Ultra-Accurate" mean if it doesn't actually use anything resembling ST2084 or something along the lines of BT2390 or some kind of home brewed tone map? How is it ultra accurate if it can't even do 709 color let alone P3 within 2020? If you have to trick it with a HD Fury to even do HDR, the consumer is being LIED to, plain and simple.
It seems there is a little bit of a difference in how we perceive the job of calibration. My job isn't to season a person's display to my tastes, it is to calibrate the image so that it is accurate and faithful to the intended image. From there I can educate a user on options for their own seasoning, or try to inform them of the pros and cons of using different adjustments to get the display to their liking, but it defeats the point of CALIBRATION to take artistic license unless the client specifically says they are looking for something else. I have been calibrating displays for YEARS and I've never heard anyone complain about the images that result. Never comments like dark, dull, washed out, or anything else. If they just want something bright and punchy, there are preset picture modes that can provide that all day long and they can save their money on a calibration. Calibrating images is not only about getting the image the way it is intended, but also educating the consumer on why we do it in the first place.
I completely understand your comments on having to fool around with the settings to get them to work, but you can still apply the same standards in measurements to see if the tweaks you are doing are actually going in the right or wrong direction. That way you can make a more informed decision on whether you're going in the right or wrong direction and what the compromises are in doing so. If you are just shooting in the dark and looking at content to do it, your settings mainly apply only to the content you are watching. Sure that may look good with a good number of items, but it can look equally awful with others. This is why the idea of a single tone map that works across all titles is so ludicrous. But if you are adjusting to a standard that material is actually mastered to (which ALL consumer video is), you have a better chance of making sure that the vast majority of the content looks the way it was intended or close to it. This puts the onus on the material to be right, not the display, and thankfully that is the case more often than not.
Please don't take any of this as an attack. I would LOVE to see your "Harpervision" setup with a bunch of projectors as I've mentioned before. Just because our methodology doesn't necessarily jive doesn't mean that I hold any ill will or don't think you can't enjoy your settings. It is just a difference in approach.

Yes sorry I wasn’t clear Kris. I was speaking of what I do with the LK970. The LK990 isn’t even released yet so I have no way of being able to do any HarperVision fun on it.......yet. I’m not even sure I’ll have to since that model and the L6000 does do HDR natively.
Based on chhanthony’s assessment though, it does appear it needs some tender loving jerking around of the settings, haha!
As far as the calibration info, of course on “normal” displays and projectors that can do full HDR BT2020/DCI I do and will perform a normal calibration. That’s all up to the client and what they want. Sometimes what I’ll do is setup one memory with some tweaks that I may find for a certain model I’ve messed with and then another regular calibration on another memory and then they can choose which to use and when.
I don’t think you’re totally understanding what I’m doing here. This isn’t how I do calibrations all the time. This is just a fun thing I do for certain models. My HarperVision stuff is only for certain model’s for certain reasons, like the Epson 5040UBs and LS10500 models that may complained were too dim with HDR, before this tone mapping craze really hit, especially with the manufacturers like Panasonic on the 820 IHD Blu-ray, etc. Its also been created for models that don’t natively do “HDR” and/or BT2020/DCI-P3 like the LS10000 and now the LK970.
I tried it on the Vivitek DK8500Z and it didn’t work as well though. That may be what your DPI you mentioned was based on. Definitely not as good as the BenQ LK970 for this!
PS - The forum blew out my replies to the other quotes I had, sorry. If anyone has my replies in your email update from AVS about this post, send them to me please or post here. I have to run and don’t have time to rewrite it all!
