As opposed to use a custom color profile with just the W xy target changed. The results are excellent and indistinguishable from using the custom color profile. No CMS required in my case. I have four different RGB gains set (one in 6500K, and then 2 from Custom 1-2). These are for high lamp in 16:9 and 2.40, and low lamp in 16:9, all with BT2020F. I also did a new curve specifically for 16:9 HDR, where I have about 70 nits so significantly more headroom than my 46 nit 2.40 setup. The results are excellent.
Can you post your latest HCFR grey scale mesurements? Hopefully with 20 points. I want to see if my Spyder behaviour is typical.
Thanks.

Sure, here you go. This was done after an autocal at 16:9 zoom setting (unzoomed), measured POST calibration with my i1D3 off the Center Stage XD screen. The only tweaks after the autocal was to the RGB gains at 100%. CMS was off and this was with the standard BT2020F color profile (no custom profile). As you can see, from 5-100 average dE was just 0.39 with a max of 0.90. Two colorcheck results are included (first one in list and the SG skin tones). Everything looks great for the gamut except the usual few rough spots, mainly due to lack of full gamut coverage, I think...

Please let me know your thoughts on these results. Thanks.

Thanks. That looks excellent.
My autocal gives me a more jagged low end. I'll have to renun it to see if it can be improved.

I have a few questions. It has been a long while since I've dabbled with display calibration including HCFR. Recently, I have upgraded my primary display to an UHD/HDR from HD/SDR. I still have an older (probably original revision A) i1Display Pro. From what I have read so far, a newer revision B is required or necessary for UHD/HDR display calibration? Is that the case? If so, how do I differentiate between the older version and the newer version when shopping for the i1Display Pro?

Second, I revisited this thread after several years and found it to be still alive. Does this mean the recent release of HCFR is a fully functional manual display calibration software that'll be compatible with my UHD/HDR display? Years ago, when UHD/HDR was introduced, I seem to remember there was talk that the way we'd need to calibrate an UHD/HDR display would be drastically different from how we had been doing it, equipment included.

Lastly, if HCFR isn't still the pinnacle of this hobby, what is a viable alternative? I stumbled across this https://www.lightillusion.com/manual...ots_guide.html when doing a Google search for "free" manual display calibration software. It seems to me there is a lot of support there but I cannot find a following here on the forum.

How to set contrast?

What is the proper way to use HCFR to set the TV's contrast? I found that when I enable the local dimming on my Sony X900F, the highlights become blown out, similar to how 100-108IRE superwhites are clipped and blank out when they are broadcast. I calibrated my TV contrast with local dimming off, but not sure if I just turn on local dimming, set near white graph, and adjust the TV contrast slider until the dE is lowest, or if there is some better method?

The new meters are certified to 2000 nits, the old ones 1000 nits.

HCFR fully supports HDR10 calibration, and includes BT2390 tone mapping for both the high (knee) end and the low (toe) end.

Feel free to try it out. Personally I don’t see any advantages of that over HCFR.

Thanks for your response Dominic. So, will my old meter suffice? How do I know if my new panel will do over 1000 nits? IIRC, the reviewer of the 2018 Vizio E series suggested my panel will not surpass 400 nits of peak brightness utilizing HDR content. Did I understand that correctly?

Not entirely sure if I understand what is meant by tone mapping for high and low end. Does tone mapping have a relation to manual display calibration?

Tone mapping can be thought of as similar to gamma for HDR. In this case, tone is the "nit" level...in an editing program, you can actually specify the tone mapping by selecting the lowest NIT level as well as the maximum NIT level, and the HDR will be mapped to fit that range...a TV set set to HDR with enough brightness to reach the maximum NIT level of that video would look "correct".

400nit is basically nice looking SDR for all practical purposes...most laptops from the last decade have about 350-400 nits of brightness.

HDR highlights can go up to 1000, 4000 or even 10,000 nits. Tone mapping essentially shoehorns all that brightness into what your display can provide (e.g., 400 nits).

I always referred to my meter as the "i1D3". But in looking at the "i1 Display Pro", they appear to be identical, at least by their physical appearance and labels. Do you know if those are indeed the same meters?

I heard that the latest generation of JVC projectors unofficially support an i1 meter. Is that the i1 Display Pro?

Wherever you heard it from, should’ve also explained that the i1Pro is not the same as the i1Display Pro.

Thanks guys. Yep, I have that meter. It's probably 15 years old and hasn't been re-calibrated by the factor ever. I wonder if its reliable at this point?

Does the i1Pro then work with the autocal in the latest versions/pjs, or does that require the i1Pro2? I'm still not sure how it could accurately do a gamma calibration reading off the screen. From what I really the i1Pro is very poor at low level light readings, especially off the screen. I remember the meter being a pain to work with, since every 10 minutes you had to put it back on the cradle and take a black reference reading. Also I lost my tripod mount for it a while ago. Is the i1Pro2 better? If the i1Pro2 is supported by the autocal in the RS1000/2000/3000 then it may be worth purchasing, if it can give me the best results off the screen, so I don't have to follow up the autocal with manual RGB tweaking...

Is there a way to delete all the Free Measures in HCFR? Sometimes I take lots of measures for example as I tweak the CMS, and it would be good to delete all these extra points accumulating on the CIE chart so I could get a "fresh" chart once in a while.

Also I'm not sure if this is a good place to give the HCFR production suggestions but I'll write this here in case so. It would be great if there was a bit more convenient way to choose the Color Checker of choice. I frequently will run a few different color checker options and its a bit disjointed the way the selection of this is inside the Preferences. Perhaps once you choose the Color Checker in the main screen dropdown, the list of Color Checker patterns can appear in a selection there.

Will my HDMI signal from HCFR be fully HDR10 in nature if I manually switch my TV into HDR10 mode? I know I can watch HDR10 and HLG files from my Windows 7 PC by switching the TV into the appropriate mode, since Windows 10 cannot spit out the HDR trigger, but not sure how the HCFR signal works.

And can anyone point me to the best post or perhaps quickly repost the settings to run a greyscale sweet in HDR10?

Thanks!

HCFR can automatically place the TV in HDR mode if you have the required video card, but that’s not necessary as long as you can manually switch the TV to HDR (ST2084 EOTF, BT2020 colour profile).

The current version (3.5.1.4) already has support for ICtCp.

I just loaded up HCFR to check my calibration and test some stuff and thought of a question. I know colorimeters can have a life and go out of calibration over time, anyone know how long a i1 Display Pro typically should last, is it a couple years or so? Is it best just to replace the meter (since its a cheaper meter) after a certain amount of time?

The eye one display pro is probably one of the most stable colorimeters, As it uses glass dichroic filters instead of organic dye based filters.

Hi, I have an LG OLED55B7V. I wish to calibrate my TV using HCFR software with a Spyder5 colorimeter. I have seen much technical information on this site but can someone please guide me. What are the correct settings for HCFR using Spyder5? I am selecting the OLED B7 2017 as the display type. I wish to calibrate to D65 standard. I am using HD709 setting. All other settings are DEFAULT. Contrary to opinion on here I find the settings for both Warm 1 and Warm 2 produce a white balance well down in the blue. The nearest I can find to adjust is the MEDIUM setting which when adjusted to produce the D65 standard appears a bit blue. All the measurements after calibration are well within specified parameters for D65. Am I missing something here or am doing things correctly? What I am really asking is, what is the starting point, because if that is not right, nothing else will be!

Does the ambient lighting (time of day, room lights,...) affect calibration, and if yes, what are the ideal lighting conditions during calibration? Thank you.
