Nvidia Shield LUT Calibration

[jhomeassistant]

I'm using the F3 firmware on my MS2130.

I can't seem to get accurate color reproduction with an SK6812 cold white LED strip when using a Nvidia Shield as the source. I've tried downloading the provided MS2130 LUT table and calibrating my own LUT table both with an HDR windows PC as well as using an SDR browser on my Shield.

In all three cases I have to lower the green and blue temperature to around 160-180 from 255, and the red to around 220 from 255 for somewhat accurate color reproduction. These are just rough ranges and could be better calibrated.

Are there any known issues when using a Nvidia Shield or could I be missing something?

Thanks!

Hi
Which depth of color you are using on Windows (ex. 10 or more bits RGB)? Did you disable all Windows features (mainly Windows 11) that can affect calibration like night colors, auto-hdr, automatic manage color for apps, graphic driver options for colors on default etc ) You can test new calibration feature, completely rewritten:
#896

This is my results using Windows 11, ms2130 (F3, 1080p yuv) and Firefox browser with new LUT calibration:
