What would be the best practice to calibrate the AUO B140QAN02.0 of my ThinkPad X1Y3?
Especially what would be the best .edr or .ccss correction for this panel (using an i1DisplayPro)?
If I understood this right, I’d have to set a brightness level, leave it and then calibrate it. Then leaving the brighness at the set level after calibration or otherwise calibration would be worthless, right? Or maybe calibrate for each of the 10 brighness levels the ThinkPad offers and choose the calibration files accordingly?
I also was digging into dithering on my Intel HD620. There’s a tool (called ditherig, yes ditherig) that can disable dithering on some Intel GPU’s:

I had success on disabling dithering and therefore got rid of that inherent banding my display showed.
Furthermore I hacked my Bios to enable 24bit PanelColorDepth (default 18bit) . So this panel shows now 16.7M colors, which I think is important for a calibration.
Intels GPU LUT only offers 8bit right?
Any advice is appreciated.
Calibrite Display Pro HL on Amazon

Dithering: DWMLUT allows dithe ron al GPUs but in extreme low gamuts like TN 60% sRGB in laptops with 6bit panel… it mat be too difficult.
IDNk about that tool you link.
AFAIK current iGPUs 8bit no dither out of the box.Thank you very much for your reply here. I was hoping for that.
Here’s some more info (in detail) about the panel:
Seems to be a good one (100% sRGB, 99.4% AdobeRGB).
I also found 4 colorimeter corrections for the display (Lenovo B140QAN02.0) in the database

What’s your idea of getting this baby calibrated with DisplaCAL and an X-Rite i1Display Pro?

Any help much. much appreciated, Vincent.

Looks like some crippled WLED PFS without P3 red. There was a sample of this insise “PFS family” set in bundled CCSS… but since review did not plot spectral power distribution (SPD) we cannot now.
It’s TOTALLY USELESS to make a review with an spectrophotometer and do not plot SPD… when will they learn… when…Seems to be a good one (100% sRGB, 99.4% AdobeRGB).
That’s false, Panel can be the most shitty one:
-Backlight type (LED type and chemical composition)Â gives colorspace coverage (& uniformity) <— This is what you mark, coverage, not related to panel type or quality at all
-Panel type gives you some “native” TRC, uniformity, contrast, viewing angles & response times.

Matrices (CCMX) are not portables between displays & colorimeters, the are made for ONE display and ONE colorimeter.
Spectral cprrections (CCSS), which are SPD samples can be shared between i1d3 users for same models or LED typesWhat’s your idea of getting this baby calibrated with DisplaCAL and an X-Rite i1Display Pro?

It’ll try PFS family (PFS_Phosphor_Family_31Jan17.ccss) due to native red being clipped to AdobeRGB red.
If you 2D plot the whole set (4 o5Â displays with 4 WRGB samples each one) you’ll find the cripped one as one that has a hump in shortest red wavelegths… you try without spliting the family.And this is a guess (an edducated guess based on display primaries). Without an SPD plot we cannot know.
If whitepoint is visually very off after calibration, “maybe” that guess was wrong but may be your eyes too… so withput an spectriophotometer is guessing
