Smartphone screens have become much larger compared to a decade ago, but they’re still small when compared to monitors or TVs. However, if you have a capable Android phone and the right cable, you can display content from your phone on a bigger screen.
While most apps don’t change much when connected to a larger display, a few apps offer unique features that make dual-screen use more exciting. Below are some of the best Android apps designed to take advantage of external displays.
What Is a “Capable” Android Phone?
Not all Android phones will show special features when connected to a larger display. Many simply mirror the phone’s screen, such as Google Pixel 9 devices. Others, like the Samsung Galaxy S24 series, offer a desktop-like interface when connected, thanks to DisplayPort Alternate Mode, which sends a video signal through the USB-C port.
When Android detects an external display, some apps can show a different interface on each screen. This is made possible by the Presentation API, an underused feature that allows apps to project a unique UI onto an external display. Though few apps utilize this, the ones that do can offer great experiences.
1. Read Speaker Notes While Presenting in Google Slides
Google Slides uses the Presentation API in a practical way for presentations. When connected to an external display, it allows you to present your slides on the big screen while displaying your speaker notes on your phone. This can save you the hassle of juggling a laptop or tablet during presentations.

To use this feature, tap the cast/present button in the toolbar and choose “present on the connected display.”
2. Play Nintendo DS Games with DraStic
Playing Nintendo DS games on an emulator can be tricky due to the console’s dual screens. DraStic, a popular DS emulator for Android, offers a smart solution. It allows you to display one DS screen on your phone and the other on the external monitor, making games more enjoyable and easy to play.
You can select which screen goes where by opening DraStic’s settings and navigating to Video Settings > External Display Mode.
3. Use a Clean Camera Viewfinder with Filmic Pro
If you’re into professional photography or videography, Filmic Pro has a fantastic feature that utilizes dual screens effectively. When connected to an external display, Filmic Pro shows the camera’s clean viewfinder on the big screen while keeping all the camera controls on your phone. This makes it easier to focus on the shot while having full access to controls.
Filmic Pro’s clean HDMI output can elevate your mobile videography, giving you a clear view of what you’re recording.
Final Thoughts
These are some of the best apps that take advantage of Android’s dual display capabilities. While more apps may support external displays in the future, these apps already make the most of the Presentation API.
