always confused ... which color mode to select on monitor

[Ruud uit de Graaf]

I'm unsure what color setting to use for a monitor, before I start the calibration.
I fully understand, that once chosen and calibrated, the calibration is only valid in combination with this monitor setting.

This time for a monitor for a friend, which is wide gamut (DCI-P3) monitor, with the options shown in the table below (picture)
Which one should I chose and why ?

I post it here, since there is no separate color management section on this forum.

Thanks!

You want to calibrate the monitor for photo editing? I'd say the only option that makes sense is S-RGB. DCI-P3 isn’t offered, might be under the HDR settings.

hi DirkPeh,

Yes, I want to calibrate the monitor for editing, and make use of the wide gamut (DCI-p3) capability.
There isn’t a mode called dcp-p3 (neither in HDR), but I'm sure one or more of the modes listed are.

Every monitor (this isn’t mine) has different modes and only by experimenting I gain confidence that the one I select is the right one. Most often this is after some unsuccesfull attempts…

For reference, not so much for the OP:

34" LG 34WP85C - Specifications

Manual:

LG 34WP85C-B.AHK Product Support: Manuals, Warranty & More | LG HK

The manual seems to make no explicit mention of gamut.

I might try "custom", in the hope that it will place no restrictions on the gamut.

After profiling the monitor, I'd check the new ICC profile to see whether it's full gamut or not. (I use the "profile info" utility that is included with DisplayCal/Argyll CMS. It'll work with an ICC/ICM profile from any source.)

Thanks Bob,

that is what I do now : I chose one and after characterizing/ calibration I check if it was the right one.
for myself I use the custom and pre tune the monitor as good as possible so the calibration has to make smaller adjustments. This extensive method is not always possible when helping a friend …

I am pretty sure that HDR means DCI-P3, DCI standing for digital cinema initiative.

Makes sense if you compare DCIP3 to sRGB.

https://www.tomshardware.com/reference/what-is-dci-p3-color-a-basic-definition

For HDR it isn’t bright enough (300 cd) like even many professional photo monitors. I would stay with sRGB for calibrating.

On the other hand LG rates the panel as higher quality (the 8 in the model number, they rate the panels 5/6/8) and DCI-P3 95%. I have a UN32880. Same brightness and I don’t use HDR on it.

 

[Ruud uit de Graaf]

Thanks. I’m not planning on using the HDR mode (my cal.kit doesn’t support it, and I do see little use for that. The DCI-p3 gamut might be interesting though ….

I wonder "HDR" in the monitor settings refers to a wide gamut, or an actual HDR mode?

In Microsoft Windows, HDR and SDR modes are distinct.

The monitor I'm looking at now is bring run with 10 bit colors in SDR mode. It lacks a "native" mode, but has a Rec. 2020 setting, which is wider than the monitor can display. I rarely put it in HDR mode. I believe that HDR mode is not recommended for phot work.

Real 10 bit or 8 bit + frc like mine?

Real.

But 8+2 is supposed to be functionally nearly the same. There are expensive monitors for content creation (e. g., BenQ SW321C) that use FRC.

My LG 32UN880 does 8 bit FRC and overly is reviewed very good for photo editing - as always related to the price. Most reviewers seem to agree that with a brightness under 300 it isn’t suitable for HDR.

I'm unsure what criteria they use for declaring a monitor suitable for HDR.

My OLED monitor (Philips 27E1N8900) doesn't have an especially high brightness, but it seems pretty bright in HDR mode in the dimly lit room where I run it. It might not be suitable to function as an HDR TV in a brightly lit room.

AFAIK OLED screens like yours are far superior for HDR than IPS screens like mine. IPS is still better for photo editing at reasonable costs.

IPS can be brighter than OLED.

OLED has "perfect" blacks and less angle of incidence effects than IPS.

Some IPS displays can have a wider gamut than some OLED.

My main gripe at the moment is that Microsoft seems to have made a bug in Windows 11 24H2 that prevents profiling software (Calibrite Profile, DisplayCal/Argyll CMS) from working properly. It appears that the profiling is done to an sRGB default. 24H2 went public around October 1, and builds that have come out since then continue to have the bug.
