Introduction 

This article explains the use of DPI (dots per inch) scaling to adjust the appearance of the Android user interface and applications on Amino H-series devices.

 

Prerequisites

This article assumes you are working with Amino H-series devices, running firmware version 25.6.2540.10R or later, deploying Android applications where UI scaling is important, and using Orchestrate or USB-based provisioning to configure devices.

 

Summary

This parameter enables customers to adjust the display scale (DPI) using a simple percentage value, allowing for easier control over how applications appear on different screens. It helps ensure that app interfaces scale correctly to fit TVs or digital signage displays, improving readability and usability.

 

Parameter

system.display_scale=VALUE

 

  • The value represents a percentage of the device's default DPI setting.

  • Valid range: 50 to 200

  • For example, 100 keeps the default DPI, 125 increases UI size by 25%, and 75 reduces it by 25%.

  • The change takes effect on boot, when the INI cache is present or updated.

Using a percentage makes it easier to adjust the display size.
