Thats good to hear i have not made a complete mess of it, yeah all readings were taken using the same settings. Tried to do hdr again last night, not really having luck with this, been told with my particular tv that getting the eotf and 2pt balance tracking is what gets best results, i can gdt them ok but not as clean as i would like, colour wise i am baffled, obviously my tv cannot reach full p3 or bt.2020 so i don't expect it to reach the targets but the measured points are all over the place, worse is, when trying to adjust some of them, hcfr does not register any changes no matter how much i tweak a colour. Im sure i have a option wrong in the preferences options.Looks very good. The red and magenta saturation sweeps look slightly "inconsistent". Were all the readings taken with the same settings?
There’s a thread on using HCFR to calibrate HDR for Epson projectors:hello guys
it's been years since i last used the fantastic HCFR. for calibration and i only used it for for SDR. calibration what i want to ask, can HCFR. do HDR. ? is there any workflow/guide for HDR. that i can start with? in saying that im calibrating a JVC x7900 projector for HDR. mode. and im using the i1 Display pro
Is there any guides for hdr tv's 😂🤣😂🤣There’s a thread on using HCFR to calibrate HDR for Epson projectors:
The same principles apply to JVC projectors, although it’s much easier to use JVC’s own Autocal.There have been some very good conversations past week or so on various other threads regards calibrating the Epson 5040/6040 for HDR. These threads were... http://www.avsforum.com/forum/68-digital-projectors-under-3-000-usd-msrp/2563857-official-epson-5040ub-6040ub-owners-thread.html...www.avsforum.com
Hi,Hi Mike, what settings are available to you when in HDR mode on your Samsung Q90R? What are you having trouble with?
Hi,When measuring, I'm not sure what is good colour results and what is not due to the tv not hitting the reference targets.
It looks like in your screen capture that the color space is set to Rec2020. Your Samsung display is not going to be able to match that. According to Rtings - Samsung Q90/Q90R QLED Review (QN65Q90RAFXZA, QN75Q90RAFXZA, QN82Q90RAFXZA) - the Samsung Q90R comes close to matching the P3 standard.
So, if the Samsung is letting you calibrate via the Custom Color Space in HDR mode then I suppose could try matching the 50% saturation targets instead I would think. There may not be much you can do with color calibration in HDR mode. I would think getting the grayscale balance set is more important.
The colour space should be Rec2020/P3 (P3 in Rec2020), not "straight" DCI-P3. (However, it doesn't make a lot of difference if you're using external patterns.).Hi,
Actually doing the calibration is ok in terms of measuring things, its just im not 100% sure if i have the hcfr options correct.
I have selected manual patterns (which i use spears and munsil uhd disc for) or the hdr10 patterns i downloaded.
Use the 10bit targets (hdr10 bluray)
I selected the st.2084 eotf
Dci p3 colour space
Color checker GCD classic
Master minL 0, Master MaxL 1000, Content MaxL 1000 & Frame Avg MaxL 400.
Color Difference Formula CIE2000.
I just not sure if i have it set correctly to measure hdr correctly, do them setting sound ok? Everything else is at default.
When measuring, I'm not sure what is good colour results and what is not due to the tv not hitting the reference targets.

Hi Mike, what patterns were you using to measure when adjusting the 2 point controls? Or were you doing a full grayscale measurement run after each adjustment to the settings and not seeing any change in HCFR?I give up with hdr, far too complicated to do, 1 minute it seems to work the next it does not, very difficult to try and adjust 2 pt white point if when making adjustments HCFR does not show me any changes. So pushing the red pixel does not increase it, just stays at the same %.
Green is way oversaturated in the HDR calibration. Keep in mind you cannot stretch the gamut beyond the display's gamut limits; attempting to increase the saturation will only make things worse.Here is all my calibrations i have done:
Day & Night mode
Hdr movie mode
Sdr game and hdr game mode
The game modes and hdr mode were the most difficult. I think the day & night files will be ok but not so sure about the game and hdr files.
