Why is my calibration too warm?

[FoxAdriano]

Hi, I have to admit that I have no experience with DisplayCAL, and I have no experience with monitor calibration in general. I’m just getting started with DisplayCAL, but I’m having some problems. My monitor is an LG 27UL650 monitor (4K) from a few years ago. I use an old i1 Display Pro to calibrate it. But my colors are too warm. In other words, if I watch videos on TV, they have balanced colors, but if I watch them on my monitor, the colors tend to be red and too warm. This is how I configured DisplayCAL; look at the photos. Where am I going wrong? Thanks for the info.

If this display has 9x% P3 it is not white LED. It could be W-LED PFS phosphor. Also you asume that your TV has whitepoint right, and that may not be true. Measure it and remember to apply the proper colorimeter correction.

IDNK about that display but if it has typical 1000:1 rec1886 is likely to be a wrong choice. Go to 2.2 as an starting point.

“but if I watch them on my monitor, the colors tend to be red and too warm”

Maybe you are watching videos non color managed. Use color managed video players like MPC + madVR or others like that. Youtube on a browser is likely to be non color managed at all, so they mat look weird unless you apply a system wide sRGB simulation by GPU (novideoSRGB, amd driver, DWMLUT) or by monitor (preset or HW cal).

Sorry, I’d like to explain better. I do video editing, but I haven’t watched videos on TV that I created with the warm settings I have on my PC monitor.

In other words: a previously created 4K video, when I watch it on TV, has true (beautiful) colors, but when I watch it on my PC monitor with the profile created with DisplayCAL, I see warm colors with a slight red cast. I don’t understand “white LED,” so where can I find this option?

So in the “Tone Curve” box, it’s best to change from Rec. 1886 to “Gamma 2.2.” Is that right? Please look at my photos in the first post. What else should I change?

Thanks again.

Which content colorspace? which TV setting/preset? Did you measure TV to see if it’s off? (you can use HCFR a DisplayCAL cousin that looks like CalMAN for that task, remember to apply a suitable colorimeter correction for  your TV)

but when I watch it on my PC monitor with the profile created with DisplayCAL, I see warm colors with a slight red cast.

Which player, which color management settings?

Lileky theres is little misconfiguration on your displaycal settings (chosing colorimeter correction, mosty and minor gamma/profile type changed), but lack of color management when playing videos on your computer monitor. Correct settings in DisplayCAL/Calibrite Profiler won’t help you till you fix the later.

I don’t understand “white LED,” so where can I find this option?

1st screenshot, colorimeter correction. IDNK if your LG display is White LED or W-LED PFS, but if it has 9x% P3 coverage it is not “white led” for sure.

So in the “Tone Curve” box, it’s best to change from Rec. 1886 to “Gamma 2.2.” Is that right?

For a general purpose monitor, yes. For video editing you’ll need color management that reencodes Rec709 content g2.4 or whatever you are using to display colorspace.
Adobe suit uses display ICC in OS, Resolve can use ICC in macOS. In windows you’ll need a LUT3D or simulating Rec709 at system level on GPU (novideoSRGB/amd driver DWMLUT)

Please look at my photos in the first post. What else should I change?

Explained before.

Thanks again.

You are a wonderful person: professional, kind, and helpful. I thank you so much. But since I don’t want to waste your time and bother you, please don’t reply to me anymore because I understand very little of what you wrote again. Of course, I will read and study what you wrote, but I don’t have time right now, and I would have preferred if you had replied with the photos I attached in the first post. In other words, I would have preferred if you had chosen the exact text and numbers in the various boxes for me. This is because I don’t have time to study right now. I’m in a hurry. I hope you don’t take offense. Sorry for this post, but I really didn’t understand you very well. Maybe I’ll understand you better in a few days, once I’ve studied. 😉

As a general rule, do not buy things that you do not understand. Learn first, buy after. This helps to avoid “I need this in a hurry but IDNK what to do”.

As said before, a set of “correct” settings  (whatever they be) in DisplayCAL or CalibriteProfiler won’t help you if you lack of basic color management knowledge if you are playing videos on native gamut colorspace.
This happens a lot because almost new multimedia displays are P3 widegamut but your former display usually was sRGB-like.

if i’m not mistaken this screen has 99% P3 gamut
try changing the correction in displaycal to PFS Phosphor WLED and adjust the white point to the coordinates like i usually use xy 0.3125, 0.3313
