Checked this tonight. If I use the test pattern on the S&M disc with the Panasonic UB900 it does add obvious ringing to the stripes on the left side. If you take chroma sharpness down you can eliminate the ringing, but it destroys the chroma resolution in the upper frequencies. If I tried the Oppo 205 it was fine. I fed this through my Radiance Pro (4:2:2 out of the Oppo and out the Lumagen, as per Lumagen's recommend setup) and no issues at all. Resolution patterns looked fine and no ringing.
It has equal effect on 1080P and UHD, i set chroma sharpness to -4 with all content. But with 1080P upscaled to UHD it also adds luma ringing, so there you also need to take the luma sharpness down on both settings. I know there has been some recomendation to set edge correction to 1 for BD to UHD upscaling, however that just remove some ringing and introduce another.If playing with the S&M chroma multiburst you should start checking straight out of the player to the display, no processing if possible, so eshift off, and go turn things on off and adjust see how it behaves. Just be carefull not to put to much attention to 1 specifik pattern, use multiple patterns to make sure you dont introduce distortion or artifacts in other type of content.
I would also think the XBOX, OPPO or Pioneer would be the best BD/UHD player to feed a Lumagen, would be interesting if you could share the Lumagen Pro chroma loss, if its identical to the previous models or different, if it have game mode, try flip that on off with the S&M chroma multiburst, and ill think you see some Panasonic effect, on the older Lumagen it boosts chroma and adds a slight ringing with game mode on.I prefer 422 in 422 out game mode off and accept the moderate chroma loss in my Lumagen processors.I can imagine that the -4 chroma sharpness with the Panasonic, adding some chroma loss in the player plus whats in the Lumagen will be a bit dull to look at.
The new Radiance doesn't have a game mode, but there is no issue with ringing. I'm fine with the limitation of 4:2:2 though, reduces bandwidth requirements, enables 12 bit to the display and all the other benefits I'm getting from the Radiance (LUT calibrations for SDR and HDR, tone mapping, scaling, etc.).
As Kris mentioned before, at this point in time, you really need proper tone mapping to get a great looking image from UHD Blu-ray on a projector. I suspect the Lumagen Pro is out of reach for most people. A very cheap (relatively) solution would be to use madVR for UHD blu-rays. You could piece together a PC powerful enough for around $500-$600. I suspect the chroma upscaling (and resolution upscaling) that madVR uses is better than what can be found on the Lumagen Pro. madVR has the unfair advantage of having a much more powerful processing solution than what is inside the Lumagen. If I lived closer to Kris I'd invite myself over and we could do a little shootout. If there was enough interest, I'd be more than happy to build HTPCs for people who've never done it before.
Chad B calibrated it for me, not sure exactly what he uses to be honest. I saw it last weekend watching Hotel Artemis. It's loaded with instances from start to finish. I attached a log from Chad's calibration. he uses 7500K to color from for HDR he said and created a custom 2020 profile so to not engage the color filter I believe.
Hotel Artemis is a 4K movie but it is not HDR or 2020 color. So you’re artifacts are probably due to using the wrong picture setup with this disc. Just FYI.
Like the " Brawl in Cell Block 99 " 4K Blu-ray ? Interesting.
Correct. I still do have the Artemis 4K release, but I saw someone did the dump on the disc info and it is 4K 709 non-HDR. So if you were using a mode you had setup for HDR, it should obviously look really weird (from not only the gamma but the wider color gamut).
Went back and viewed a few scenes of Hotel Artemis and changed some of the gamma settings and color profiles and the noise I was seeing appears to be related to the very high saturation of this particular film as you mention above. There is a scene in the beginning when Jodie Foster answers a phone sitting up in her bed with a lamp on next to her and the whole scene is low APL w/ lots of red tones. When I switched from Chad's custom gamma to HDR the reds still looked over saturated, but a lot of the shadow detail was gone. In the scene part of Jodie Foster's bed is in the bottom left corner and when I switched out of the custom gamma to the HDR gamma the pattern on her bed cover completely disappears and the entire scene gets significantly darker. It's a testament to Chad's abilities as a calibrator when you A/B the work he does for you. Kris thanks for your help and you can buy Hotel Artemis UHD copy on amazon for $21.00, it seems as though it's loaded with torture material. It's not a bad movie either if you like John Wick type plot lines.
