Only HDR.Can the disc be used to caliberate SDR profiles on a 4k tv? or the disc only enables HDR caliberation?
Thanks
AFAIK, LightSpace doesn't generate metadata at all. It relies on whatever you're using as a pattern generator to do that.Ryan, is there any way to compare Metadata with LightSpace Metadata?
Hi jayraysaiz,What is the difference in the LG OLED patterns compared to the patterns in the ChromaPure sections? I generally use the ChormaPure software to calibrate my OLED. Is it best to use the LG or the ChromaPure patterns?

Hi Pres2play,At present, the Linker is outputting YCbCr, but after reading the LightSpace Connection thread, I think it's just a setting in LightSpace that I've overlooked and it's resulting in the pattern clipping above 235.
I hope to hear from LS on this tomorrow. Thanks.
I don't understand why you would expect an upscaled 1080p non SDR image to be comparable to a UHD HDR pattern displayed through the Oppo?At present, the Linker is outputting YCbCr, but after reading the LightSpace Connection thread, I think it's just a setting in LightSpace that I've overlooked and it's resulting in the pattern clipping above 235.

Thank you Ryan for the generous information.Hi Pres2play,
I'm not quite sure what is causing the difference in readings. All of the 100% stimulus grayscale patches within my pattern suite are true 10-bit 940|940|940 (235|235|235 8-bit) within the limited range for video. Here is a list of spec's and metadata for my patterns:

Just as a point of reference, here was the measured difference between my disc and the AccuPel 6000 on a 50% stimulus patch:
x...............-0.0005
y...............-0.0001
cd/m2........-2.58/-2.4%

Hi Pres2play,Thank you Ryan for the generous information.
I measured both 10% windows using masking tape and found the patterns on the disc are larger (horizontally) than the LS patterns. To match the Nits reading I have to increase LS pattern size to 11%.
I second this. I love how easy and clean the menus are to look at and navigateWow, ok.
BTW, you did a beautiful job. Really like adding the disc to my collection.
Hi Frank,What level is the near black pattern at.
Why no black pattern at reference black of 64
Thanks
Hi northrob,Hi Ryan. I have a question. If Maximum Content Light Level of your disc and digital download files is 1000 cd/m2 how does that effect the test patterns above that (code 721-940)?
You will at least need a colorimeter along with this pattern suite to get started as long as you already have a computer/laptop to load the software. There are some free calibration programs you can download that have limited or basic functionality.Pardon my ignorance on much of this... I'm fairly new to the calibration world. Particularly UHD HDR. Can these patterns be used by a layman like myself to adjust settings and calibrate, or does it require special equipment, etc.? Trying to find best settings for Digital Cinema HDR on my Epson 5040 and looking for avenues to achieve that on my own since I cannot currently afford ISF calibration.
Alas, the Colorimeter takes it out of my affordable price range at the moment. Other suggestions on how I may do some HDR calibration on my 5040 in the meantime?You will at least need a colorimeter along with this pattern suite to get started as long as you already have a computer/laptop to load the software.

i1display Pro is about $239. (Get the 2017 version - it's faster in the Black Regions.) Have a friend in Canada? Get them to buy it, since it will be cheaper when paid with US $s. Postage may be an added factor. Customs - it's a gift.Alas, the Colorimeter takes it out of my affordable price range at the moment.
