external monitor - Imac anda MacBook Pro M1 - color problems

Hello

I have a MacBook Pro m1 and an iMac late 2020 with color issues on the external monitors. I've already swapped one monitor for the other, and they do the same thing. I've formatted the iMac, and that didn't solve it either. I even replaced the cable with a new one.

Half of the monitors have a slight red tint, but it still affects the color correction of images, and my eyes always get tired.

Since I've already followed all the steps above, I think the problem is with OS Catalina 15.5, as it didn't work before.

This is a very bad Apple bug, even though they're the best for image editing.

You can see the same image duplicated, whether in black and white or color, but the image isn't the same color on both sides of the screen.

Any help?
