The Acer Display Color Controller is a software utility developed by Acer Inc. that is designed to allow users to adjust and manage the color settings of their Acer monitor. This tool is typically bundled with Acer monitors that support advanced color calibration features, such as those used for professional photography, video editing, and design work.

The Acer Display Color Controller allows you to:

• Adjust the color temperature of the display.
• Calibrate the monitor for accurate color reproduction.
• Use preset color modes (like sRGB, AdobeRGB, etc.).
• Manage brightness, contrast, and gamma settings.

This driver and software utility is typically required for Acer monitors that come with special color management features. It's often used in conjunction with the display's built-in hardware calibration, which is common on high-end Acer monitors.
