So here are the results:
IFS Expert Bright Room (Factory) Oled Light 60

So there a small differences in using the Profile Meters.
The question? Which is the correct one?

Factory default is so accurate?

I don´t see differences between different EDRs, do you see such of small difference in real?
There may be bigger variable between i1D3 unit to unit.

Hi,

The scaling of the charts don't help a lot, can you make them to focus to smaller range? ...to be able to see better the differences.

Also when you compare dE, as dE don't show the direction of the error, don't means that one dE with 0.6 dE and one with 0.7dE, that they have difference only 0.1dE, as if the first error tent to have error in red while the second error tent toward to green, the distance from one color to another it will be larger.

Set RGB balance chart to +-10 range or use a page where we will be able to see xy differences.

Thank you all for responding and testing this. I appreciate the tutorials in letting me calibrate at the amateur level. @WiFi-Spy Thank you.



Just trying to get the most I can for my money. I know there is only so much this meter alone can do.

Those are almost same, so do we know renaming .edr file work or not?
Maby that little difference is just normal variation between different measures?

Actually, the max dE is always about 1 value higher with the OLED EDR compared to the FSI_XM55U (color and grayscale), while the average value is about 0.5 higher.
I've made several measurements to rule out variations.
Especially the blue curve is always significantly different if you compare the two EDRs.

I also am sure CalMAN is using the file (verified by deleting the file while CalMAN is running). However, I of course can't tell what CalMAN is exactly doing with it.

Unfortunately I can't tell which of the three (actually two) modes is the least inaccurate one, I simply don't have the equipment for it. All I can say is that the difference between Raw XYZ and the FSI_XM55U is pretty high.

When you calibrate using the XYZ RAW, when you will verify that calibration using an EDR spectral correction, it will report more errors, since you evaluating the calibration performed with RAW XYZ (which is not enabling any EDR spectral correction).

Your testing confirms that the replacing/renaming EDR method Tyler suggested works in CalMAN.

If you compare the xy reading you have by measuring 100% White using LightSpace ZRO with FSI EDR table vs. CalMAN with modification to use the FSI EDR, it will double confirm that the results from CalMAN are valid.

So no further test will be required, just when we will see a CalMAN user to measure with RAW XYZ or OLED table, other users will have to info him to do that trick, taking the EDR file from LightSpace etc, as that EDR will not go officially supported by CalMAN.

Thanks for confirming that the file replacement method works. Maybe someone that owns both the i1Display Pro and a spectro could do a comparison with that too, so that we can see the difference between RAW XYZ, the replaced WOLED EDR and an individually corrected device?

I think it is better to confirm the reading in lightspace before saying it works, as Ted has already explained above. I have a c6 so I don't think I can confirm the white patch reading using the FSI EDR in calman.

CalMAN with the replaced EDR file indeed does show the same values as LightSpace ZRO with the WRGB OLED profile.
So I can confirm replacing the file does work.

Here's another list of values for 100% white (SDR Rec. 709) showing the variance between the modes:

__ Raw XYZ ___ OLED ____ FSI ___
x 0.3120 | 0.3105 | 0.3109
y 0.3286 | 0.3236 | 0.3253

My C9 is coming next week. I have a i1 Display Pro and usually use HCFR to calibrate. Anything I need to know, or any profiles I need? I've had issues in the past with it not producing an accurate calibrate on my E6 until I loaded someones profile. I've also never attempted to calibrate HDR, and I have no idea if HCFR even supports that.

Is there a recommend preset/settings starting point for calibration anywhere?

Try checking the main HCFR thread. Lots of discussion there.

You know there is internal patterns at C9 and you can do autocal by investing 145$ to CalMAN Home for LG software?

https://kb.portrait.com/help/lg-2018...-autocal-guide
https://calmankb.groovehq.com/help/c...lg-walkthrough
https://calmankb.groovehq.com/help/l...tern-generator

However, there´s some problems with this software, some HDR/DV presets will give raised blacks, I would wait until it´s fixed and then buy it.
Updates are free only first year, after that you have to pay another 145$.

It's also worth noticing that you won't be able to verify the calibration results for the HDR and Dolby Vision modes with the internal pattern generator and CalMAN Home.
Plus the color space calibration for these modes is very limited, to my understanding you won't be able to create a 3D LUT but only a 1D LUT.
Portrait Displays always said sth. like "trust us, we've verified the resuls of the HDR calibration with the internal pattern generator are accurate". The current issues with the raised blacks shows how much this promise is worth ... Just my two cents though.

To be fair: SDR calibration results with CalMAN Home however seem to be good and acceptable.

We are working closely with LG on this issue. The current understanding is that this is an LG FW issue and not a bug in CalMAN. I will provide an update when I have more information to share.
