Calibration reports for Eizo

Hello!

I did a PreLUT Calibration and PostLUT Calibration report and I'm wondering if the readings seem right?
PostLUT it seems the RGB only shows the blue channel and the blacks seems high? But that's within the range of the monitor specs.

https://www.dropbox.com/sh/yn3f7xf7udjsglc/AACrRJTTEWByJU1dcxFsPhmRa?dl=0

I'm using an EIZO CS2420 that's WLED
6500K
Native Gamut
Gamma 2.2

Probe:
i1D Pro

Probe Settings:
Sync Mode: Burst
Extra Delay Time: 0.5
White LED

Resolve 16 as the TPG with Video levels.

I found that using Full Data via HDMI on the monitor and Full on Resolve gives a levels mismatch via the color bars and smpte generator but video and limited does not.

The reports look reasonable, but not the best I have seen.
You don't mention the Integration time setting, and I'me not convinced Burst is the best mode to use for an LCD, and what about Intelligent integration?
See: https://www.lightillusion.com/i1_display_pro.html

And White LED is not the right preset.
PSF Phosphor is - I think?

And RGB Separation shows NOTHING, as you have no viable data with the Quick Profile you used.
(Info in the User Guides in that.)

As for black levels - that all depends on your specific display.
But, at 100 nits, a 1000:1 contrast ratio (as per Eizo specs) would be 0.1 nits black

Thanks for the reply Steve!

—I saw from it's W-LED from a post on Liftgammagain I think?

I reran with these settings:
—Integration Time: 0.75
—Intelligent Integration: 0.03
—Drift comp is 100

—What would you recommend instead of burst? AIO?

The image is warmer than I thought but I'll be doing another profile after adjusting the RGB "high" balance in the guide.

Hey Steve,

I did a few more rounds:
https://www.dropbox.com/sh/wxu8900o3zrp47d/AAAUTVqLNOkylULsWLnOfHkra?dl=0

Integration Time: 1
—Intelligent Integration: 0.03
—Drift comp is 100

The first is:
Pfs-Phosphor (Display's 6500)
AIO

The Second:
W-LED (with RGB High Balance adjustment on the display per the User Guide).
Burst

I'm thinking of running them with different sync settings also.
Both are now just 12^3 but if one seems more correct I'll run it at 21^3. Could you advise on which track to continue?

The display is not 'white led'.
(White LED displays are low gamut.)
It is PFS Phosphor, which is a form of white led... hence the confusion.
And as per the page I linked to, I would use Frequency mode, with Intelligent Integration.

Thanks Steve.

Integration Time: .75
—Intelligent Integration: 0.03
—Drift comp is 100
—Pfs-Phosphor
—Frequency

I'm borrowing the probe and so did a few profilings before returning it (hence the 21^3 difference versus 11^3).
The RGB balance on the 10b looks really off? 10b is a warm white when I'm generating a white solid in resolve whereas 12B is cooler and seems more "white".

When viewing a still on my iPhone 11 Pro (oled) vs the 10b and 12b and it seems more green, which is more in line with what the vectorscopes say? Could it be that the probe is off?

OLEDS suffer metameric failure.
That will be wrong, not the Eizo.

Also, you CANNOT look at white and judge its accuracy.
And a vectorscope has NOTHING to do with calibration.

You must select the correct probe setting, and rely on the reported values.

However, your 10a result is just wrong - as you say, just look at the RGB Balance result.
It is totally inaccurate.
Something in your workflow was done incorrectly.

Ah gotcha. My license has expired so I won't be able to make the new changes currently.

Was the 12a/12b more in line?
The difference there was I adjusted the color temperature via the monitor itself first.

Then do a volumetric profile >>colorspace conversion>>then profiled.

Changing the Colour Temp first will NOT make any difference, unless the change subsequently became disabled!
Basically, something was wrong with your workflow somewhere.
