If there is purple or discoloration on the edges around the screen, it may be caused by too high saturation. You can add an ICC file to solve it.
Please refer to the following steps:
Step 1: Open Windows settings, select the tablet display, then click "Advanced display."
Step 2: Click "Display adapter properties for Display 1."
Step 3: Choose the "Color Management" tab
Step 4: Please make sure the display you choose is our pen display and not your computer's primary monitor. Please identify the device as our pen display before you add the ICC file. To request the ICC file, please get in touch with Huion Customer Service at service@huion.com.
Step 5: Go back to the home page and find the .icm file in the color profile.
