SecondScreen

The essential tool for Android users who frequently pair their devices with external displays, like TVs or monitors, is none other than SecondScreen. This tool enhances the experience of screen mirroring by offering features like custom resolution and density settings to ensure the content fits the connected display perfectly. Moreover, it supports landscape orientation lock, enabling always-on desktop mode in Chrome for improved browsing, and even allows users to switch off their device's backlight to save power.

A nifty advantage of the program is its capacity to display a tablet interface on a phone when connected to an external display, which maximizes usability and provides a more comfortable viewing experience. Another significant benefit is its profile-based system, allowing customization of settings for various display types and switching between them with ease. Additionally, quick actions and homescreen shortcuts afford the convenience of launching profiles with a single tap.

Complementing these features, SecondScreen includes a suite of automation capabilities, such as turning on Wi-Fi and Bluetooth to expedite the connection process with accessories like keyboards, mice, and game controllers. It even integrates seamlessly with Tasker for those looking for enhanced customization and can trigger profiles automatically upon connecting to a display.

The utility of this tool expands with options like automatic Daydream activation, overscan adjustments for older TVs, and system-wide immersive mode. Note that it requires elevated permissions, achievable either through root access or adb shell commands, as it offers profound system adjustments including resolution changes and backlight disabling. Moreover, compatibility is optimized for devices running AOSP or Google experience ROMs, and while the application itself doesn’t offer mirroring capabilities, it works in conjunction with your existing solution, including adapters or wireless tech like Miracast or Chromecast.

To facilitate interaction, a Bluetooth keyboard and mouse are strongly recommended, as using the touchscreen might present challenges due to smaller UI elements. For enhancing productivity and entertainment when connecting an Android device to an external display, this app stands as the perfect choice.
