How to Change DPI Settings on REDMI Note 9 Pro via Developer Options

Accessing Developer Options

• 💡 To change DPI settings on the REDMI Note 9 Pro, you first need to enable Developer Options.
• 🔑 This is done by navigating to 'About phone' and tapping the 'MI UI version' multiple times until you see a confirmation message.
• ⚙️ Developer Options are then found within 'Additional settings', usually located at the bottom of the menu.

Adjusting Display Size (DPI)

• 🔍 Within Developer Options, scroll down to the 'Drawing' section.
• 🎯 The key setting to adjust is 'Smallest width', which controls the display's DPI.
• 📏 The default setting on this device is 3192. Increasing this value (e.g., to 450 or 500) will make icons and text appear smaller.
• ⚠️ Be aware that the minimum possible width is typically 320, and attempting to go lower may not be supported or could cause display issues.

Understanding Display Settings

• 🧐 The standard 'Text size' setting in the regular display options only changes the font size, giving an illusion of a different display size rather than altering the true DPI.
• ⚠️ It's advised not to tamper with the 'Display cutout' setting as it may not offer significant benefits and could potentially cause issues.
