Site Editorial Commentary：Change your device's resolution & density when connected to an external display

SecondScreen is a powerful Android application meticulously crafted for advanced users who frequently connect their Android devices to external displays such as TVs and monitors. It seamlessly integrates with your existing screen mirroring setup to unlock a superior viewing experience. This app empowers you to fine-tune your device's resolution and density (DPI) to perfectly match your external display, enabling you to maximize screen real estate and visual clarity. Furthermore, you can activate always-on desktop mode within Chrome for a desktop-like browsing experience on your TV, and even conserve battery by disabling your device's backlight while it's connected to an external display.

As featured on prominent tech platforms like Pocketables, XDA-developers, Android Police, AndroidHeadlines, Android Community, and Android Beat, SecondScreen has garnered recognition for its robust features and utility.

Before downloading, please take note of the following critical requirements:

* This application necessitates elevated permissions, which can be granted either through root access or via ADB shell commands. The app will remain non-functional without a rooted device or ADB access.
* SecondScreen is designed exclusively for devices running AOSP (Android Open Source Project) or Google experience ROMs. Compatibility with devices using manufacturer-skinned ROMs is not guaranteed.
* This app does not inherently provide screen mirroring capabilities. Screen mirroring functionality may necessitate an MHL/SlimPort adapter or a wireless solution like Miracast or Chromecast.
* The use of a Bluetooth keyboard and mouse is highly recommended, as the app can potentially reduce the size of UI elements on the device itself, making them more challenging to interact with.

Key Features:

* Effortlessly adjust resolution and density (DPI) to fully leverage the capabilities of your external display and enable the Android tablet interface on your phone.
* Employ a straightforward profile-based interface for easy enabling and disabling of distinct profiles tailored to various display types.
* Explore a wealth of configurable options, including:
* Automatic activation of Bluetooth and Wi-Fi for quick connection of keyboards, mice, and/or game conTrollers.
* Automatic enabling of Daydreams for enhanced screen idling.
* Default display of desktop sites in Chrome for a complete web browsing experience on your TV.
* Locking screen orientation to landscape mode.
* Overscan support for older TVs (Android 4.3+).
* System-wide Immersive mode (Android 5.0+).
* Disabling device backlight and/or vibration to conserve battery while connected (compatibility may vary across devices).
* Seamless integration with Tasker for advanced automation.
* Automatic profile loading upon display connection.
* Quick actions for instant execution of SecondScreen features without profile creation or editing.
* Homescreen shortcuts for one-tap profile launching without entering the app.

Permission Explanations:

* Root access or ADB shell commands are essential for modifying resolution/DPI, disabling backlight/vibration, and enabling desktop-only mode in Chrome.
* The app requires "connect and disconnect from Wi-Fi" and "view Wi-Fi connections" permissions to enable Wi-Fi through profiles.
* "Access Bluetooth settings" and "pair with Bluetooth devices" permissions are necessary for enabling Bluetooth via profiles.
* The "close other apps" permission is required to refresh the user interface after resolution/DPI adjustments. Ensure all data is saved before launching a profile.
* The "run at startup" permission is needed to display SecondScreen profile notifications after a device reboot (soft or hard).
* The "modify system settings" permission is required for profiles to lock screen rotation and adjust brightness.

This app utilizes the Device Administrator permission.
