How to adjust colors if the color tone is different on two monitors of the same model?

Question

Video cards

There are 2 monitors AOC 2757Fm with IPS matrix. When connecting a second monitor to a video card via an HDMI-DVI adapter (because for some reason there is no second HDMI socket on the vidyuhi ...), a slightly different shade is observed (in the direction of blue-green). By playing with the settings in the monitors themselves, I came to approximately the same denominator (44/45/46 on the first and 43/42/42 on the second). But the difference, although small, is still there = (
I don’t have a Calibrator, but the Windows calibration or on which site, if I understood it correctly, is bullshit, I don’t know at all who can come in handy.

Here’s what I wrote on one vorum people:
"I've been struggling with the problem of the "yellowness" of secondary monitors for a long time, but I haven't been able to overcome it yet. Moreover, the monitors are not only different in temperature, but also in brightness. If the monitors are swapped, the one that was yellow becomes normal, and the normal one becomes yellow. If there are more secondary monitors two, all secondary monitors are equally yellow and you can adjust them to each other.But you can’t match the main one.The problem is described in many English-language forums, but I didn’t find a solution there.I can knock out the results of my research:
1. The problem is present regardless of the brand and model monitor
2. Regardless of the type of cable
3. Cannot be solved by hardware calibration (calibrators from different manufacturers and different classes were used)
4. Does not depend on the model and type of video card
5. I can’t decide if I adjust the brightness and temperature with my hands.

If anyone has a solution, I will be very grateful
