Color differences between reference/GUI monitor for Resolve

[Zachary]

Hi Florian,

Been trying to calibrate both my reference monitor and GUI monitor for resolve without success (following the instructions on the WIKI).

Luminosity and gamma looks perfect and identical, but the colors differ, with the GUI monitor having more reddish tones

What could I have done wrong? Thanks so much!

Here are my settings (mostly identical, differences in Italics):

Reference monitor (Dell UP2516D – Decklink Mini)

Display & Instrument

• Display Resolve, Instrument i1 DisplayPro, Mode LCD (generic)
• Drift Compensation off
• Correction: Matrix: i1 DisplayPro, ColorMunki Display & DELL UP2516D (ColorMunki)
• Override minimum display update delay: 600 ms

Calibration

• Interactive display adjustment on
• Whitepoint: Color temperature 6500K
• White Level: 110 cd/m2
• Tone curve: as measured

Profiling/3D LUT

• Profile quality High, Testchart Auto-optimized with 1553 patches
• Built-in 3D LUT Defaults: Rec 709 Colorspace, Rec 1886 Tone curve, Absolute colorimetric with white point scaling

GUI Monitor (Dell U2312HM – GPU GeForce GTX 1080 TI)

Display & Instrument

• Display DELL U2312HM Primary, Instrument i1 DisplayPro, Mode LCD (generic)
• Drift Compensation off
• Correction: Matrix: i1 DisplayPro, ColorMunki Display & DELL U2312HM (ColorMunki)

Calibration

• Interactive display adjustment on
• Whitepoint: Color temperature 6500K
• White Level: 110 cd/m2
• Tone curve: Rec 1886 (1st attempt) as measured (2nd attempt)

Profiling/3D LUT

• Profile quality High, Testchart Auto-optimized with 1553 patches
• Built-in 3D LUT Defaults: Rec 709 Colorspace, Rec 1886 Tone curve, Absolute colorimetric with white point scaling’
• Apply Calibration (vcgt): Off (1st attempt), On (2nd attempt)

Other Info

Resolve

• Generated 3D LUT for reference monitor loaded in 3D Video Monitor Lookup Table
• Generated 3D LUT for GUI monitor loaded in 3D Color Viewer Lookup Table
• 3D Lookup Table Interpolation: Tetrahedral
• Use Mac Display Color Profiles for Viewers: Tried both on and off. Color remains unchanged, still reddish (Turning it on messed up the gamma though, I assume it’s because it applies the settings twice, once in profile icc and once in LUT)

System Info

• macOS Sierra 10.12.6
• DisplayCAL 3.3.4.1
• ArgyllCMS 1.9.2
• Davinci Resolve 14 Final
• i1Display Pro
• Color Profile Applied: Generated GUI Display Profile

Hi,

I am comparing it to two other calibrated displays that do not show almost any difference after the calibration.

Have a look at the FAQ entry about visual whitepoint mismatch.

Did you create the correction(s) yourself using a spectrometer or are they from the online database?

Use Mac Display Color Profiles for Viewers: Tried both on and off.

I definitely recommend the “off” setting and relying on a viewer 3D LUT instead because Resolve doesn’t seem to support BT.1886 when using the display profile.
