Why does the display color look different after replacing the Xiaomi 4K Monitor A27Ui?

The difference in display color between the Xiaomi 4K Monitor A27Ui and your previous monitor is primarily due to variations in the screen’s Color temperature settings. You can restore your preferred color appearance by adjusting the Color temperature in the monitor’s OSD menu.
To custom the color to your preferred temperature, please refer to the following steps:
  1. Press the button located at the lower-right corner on the back of the monitor and push it to the right to open the menu;
  2. Use the same button by pressing it downward to navigate to [Picture mode];
  3. Press the button to the right to select [Color temperature];
  4. Press the button to the right again to select [Custom];
  5. Then adjust the red, green, and blue levels to achieve your desired color balance.
