if you find a correction for the same screen, similar display or with the same panel use that else the w rgb is most likely the closest.

You mean - i1 DisplayPro, ColorMunki Display & Dell, Dell AW3420DW by 4KM (i1 Pro).ccmx?

I usually use Spectral: LCD White LED family (AC,LG Samsung), but I will try the one from the database.

Thanks, huhn.

It's not white led. well it is white led, but it's got nano-ips, which means quantum dot coating, you need to use one of the quantum dot corrections.

There is only one - Spectral: LCD Quantum dot LED (Samsung QLED Q9).

yea i'm pretty sure that one will work, cuz the q9 has ~98% p3 like the quote on yoru monitor.

they all buy quantum dot from the same place. produced by genetically engineered bacteria.

These are the available corrections from the online database http://imgbox.com/Ddloufch perhaps one of them will work? I imported them in displaycal, when I choose "auto" it selects one of the spectral corrections.

I'm pretty sure the q9 one is lab grade, I mean, it won't make a huge difference visually.

I would use the q9, if you want to use some dude's spectro, it's probably fine.


Did some googling, turns out, yea, you should use those corrections instead of the q9, apparently nanocell is not quantum. it's something else.

I see, on Auto it selects this spectral correction - http://imgbox.com/wlFXMtdZ it is one of the four available for my monitor in the database (2 matrix and 2 spectral corrections).

I'm not sure if the i1pro is better than the colormunki. double check.

This is the other spectral correction - http://imgbox.com/EWS3Rtle

The other 2 are matrix corrections. http://imgbox.com/tm162g4c

run the simulation test on all of them if you want to, but I don't think there's gonna be a huge difference.

Just look out for if any of them have the primaries in a very different location, if they're all in similar agreement, you should be fine with any of them.

These are the primaries of the two spectral corrections http://imgbox.com/t9BJcM5f

They're reasonably close. the white point looks like it's moved a bit, but that shouldn't be a problem. After calibration, if the visual white looks really off, try the other one. I doubt this would happen though.

Will test both of them, but this one http://imgbox.com/t9BJcM5f seems better than the second, right?

We can't know which one is better, unless you also buy a spectro. just because it's closer to some value right now, doesn't mean one is better, there's no point of reference.

Every measurement can also have some level of drift. If you checked it again today, it's not gonna be the same coordinate, because the temperature changed.

Prior to measurements, warm up the device running an rgb pixel fixer video for ~ 1.5 hours. The LED takes approximately 40 minutes to stabilize, some takes a little more than an hour. You want to exercise the LCD pixels as well as the LED backlight using the video, because you get more contrast out of it post exercise. If you leave a monitor in a box for a long time, the pixel gets lazy , and won't flip on all the way, exercise and warmth brings them back. Take care not to let the video get paused by youtube, or the computer/monitor going to sleep.

Leave the meter plugged in during this phase, but do not put it on the monitor.

The only thing you can go by is if there are visual anamalies. such as color casts. Then you know something may be up.
