How to calibrate a monitor with multiple points?

Question

Monitors

I got a monitor, warm on the left, cold on the right.
At first I thought that I had glitches, or I was looking at him from an angle. But then I moved the calibrator on the monitor, and yes, Red comes off on the left, on the contrary, Blue on the right.
Is it possible to somehow compensate for this effect? Is it possible to calibrate the monitor at several points and smoothly smooth out the color temperature discrepancy?

Answer 1

Alas, but simply not. Color profiles are not designed for this.
You can slightly "average" by making a calibration with a large number of samples on the whole screen, but even that is not a fact.
Of the complex - writing a shader for the OS shell.

Check if DEMO mode is enabled on the monitor. Many monitors have such a function - when you change the mode, half of the screen changes so that you can compare visually how it was and how it will become. In most cases, this works during setup, when you close the monitor menu, it either returns to the previous mode, or applies a new one. But there are options when it can be left in this form. So first go to the menu in the monitor, and reset to default settings. If it doesn’t help, there is an option to look for the service menu (on different models in different ways, somewhere not at all). Carefully! There are functions in the service menu, the incorrect use of which can lead to the inoperability of the monitor.
