Hi, im new to monitor world and confuse how properly measuring SDR and HDR in DisplayCal.
im using Xrite i1 DisplayPro
- are my setting good for measuring SDR color gamut and Delta E in Office&Web (D65, Gamma 2,2)?
- do i need correction in my monitor especially none of my monitor brand are there?
- how to measure color gamut in HDR? do i need fixed nits point to do that, or go full brightness?
- and for verification settings in SDR and HDR are Extended verification testchart are fine?
i1Display Pro on Amazon

2) yes but no data
3) AFAIK gamut volume & coverages through iccgamut or viewgam will rely on relative TRC colorspace comparisons, hence comparisions will be done against a SDR Rec2020 colorspace.
4) Maybe you want HCFR for testing factory PQ tracking like with a TV. It has embebed ArgyllCMS code for measurements.
2022-06-16 at 7:03 #35641what do you mean no data?
can you give me a link or reference to use HCFR properly?

That you provide no data
can you give me a link or reference to use HCFR properly?
There is a very long thread in AVSForum

what data do you need?

Settings (colorimeter correction) is linked to display model, actually its backlight type (+ fancy filters).
With common sRGB SDR display is easy to guess, choose White LED. With P3 displays it may get more complicated to guess if no user uploaded a custom CCSS to database.

Anyway 200:1 contrast ratio means that you have messed up with configuration (GPU, mnitor, not Displaycal). Usually it is a 16-235 range issue but it may be user mssing with OSD controls so a factory reset may help too.

its Mi 23.8″ Desktop Monitor 1C
2022-06-28 at 19:39 #35806Looks like a common LED sRGB monitor so “White LED” family correction. It may modify measured whie point coordinates.
Also check 16-235 vs 0-255 range issue and recalibrate. Try to measure contrast first to ensure that issue is solved before doing full calibration.
