Win10 how to change the system color default value

A Windows user installed the Win10 system, and changed a monitor, and found that the color of the display has an abnormal situation. This may be caused by a display setup error, or it may be caused by improper Win10 settings. Let's take a look at the solution.
Method 1
Selecting the RGB mode on the display can generally be operated by buttons on the display body.
Method 2
1. Open the Control Panel ("Where is the Windows 10 Control Panel?") and select Color Management.

2. In the Advanced tab, select System Default from the Device Profile drop-down box.

3. Click Close.
When the computer shows a display problem, we can analyze it from two aspects of software and hardware to find the corresponding solution.
