A free utilities & tools app for Android, by Braden Farmer

SecondScreen is a great tool for people who constantly use their Android devices to connect to external displays. With this application, you will be able to change the resolution and density of your device to suit your TV or monitor.

For SecondScreen to work, your device must be rooted first or has access to ADB. In addition, it is recommended to have a Bluetooth keyboard and mouse for a better experience.

SecondScreen comes with a simple, clean, and user-friendly interface, which makes the application much easier to use and navigate.

You can download it on your Android device completely free.
