Attaching a second display to your computer is a fantastic way to enhance productivity, allowing you to multitask efficiently and keep your workspace organized. Whether you’re a designer looking to utilize dedicated screen space for your projects or someone who enjoys watching videos while working, a dual-monitor setup can significantly streamline your workflow. However, if investing in a dedicated monitor isn’t feasible, consider turning your Android tablet or phone into a second monitor for your computer.
After spending a day testing various apps recommended by Perplexity AI and other sources, I found that many didn’t perform as expected. Here’s a summary of my experience and some insights that may help you choose the best app for your needs.
Problems I Faced While Using These Apps
While exploring popular second monitor apps in the Google Play Store, I encountered several limitations. Below are some commonly used apps and their shortcomings:

To prevent this, consider using your Android device as a secondary display only when necessary, and monitor your usage to avoid excessive exposure.

Conclusion
Transforming your Android device into a second monitor can greatly enhance your productivity and multitasking capabilities. Both Spacedesk and Duet Display offer viable solutions, each with its own set of features and limitations. If you’re primarily using Windows and seek a free option, Spacedesk is an excellent choice.
