DPI Scaling refers to the adjustment of the display settings on a computer or device to improve the visibility of text and images. DPI stands for "dots per inch," which measures the resolution of a display. When DPI scaling is increased, elements on the screen appear larger and easier to read, making it particularly useful for high-resolution displays. This feature is commonly used in operating systems like Windows and macOS to enhance user experience, especially for those with visual impairments. By changing the DPI settings, users can customize their display to suit their preferences and improve overall accessibility.
