Most gamers want more screen space, whether for tracking live stats, chatting with friends, or keeping guides open during a play session. Luckily, you don’t always need to buy an extra display. You can turn the phone you already own into a useful second screen. Learning how to use your smartphone as a secondary gaming monitor is easier than you might think, and it can give you an edge in your setup.

Why Turn Your Smartphone Into a Second Screen

A secondary display can make gaming more efficient. Instead of switching between tabs or breaking your focus, you can dedicate your smartphone to background tasks. Streamers can monitor chat, competitive players can keep guides or maps open, and casual gamers can use it for music controls. Turning your phone into a small gaming monitor frees up your main screen for the actual gameplay.

The Apps That Make It Possible

The most practical way to use your smartphone as a secondary gaming monitor is through specialized apps. Tools like Spacedesk, iDisplay, and Splashtop allow your phone to mirror or extend your PC’s display. Most of these apps connect over Wi-Fi, though some also support USB connections for lower latency. Once installed, your smartphone can function just like a mini monitor, giving you more space for whatever you need.

Setting It Up

  1. Download and install an app on both your computer and your phone.

  2. Connect both devices to the same Wi-Fi network or use a USB cable if supported.

  3. Adjust the display settings on your computer so that it recognizes your smartphone as an extra monitor.

  4. Drag windows or apps to your smartphone screen and arrange them the way you like.

In just a few minutes, you can transform your phone into a gaming monitor that works alongside your main display.

Optimizing Your Smartphone Monitor

To get the best results, position your phone where it’s easy to glance at without pulling attention from your main game. A simple stand can hold the phone upright on your desk. Lower the brightness slightly to save battery if you are not plugged in. Keep a charger nearby during long sessions, since running your phone as a monitor can drain power quickly.

Creative Ways to Use a Smartphone Monitor

When you know how to use your smartphone as a secondary gaming monitor, you can get creative. Many gamers use it to track frame rates, follow live patch notes, or keep Discord open. Others like to stream music services or keep social media running in the background. You might even use it as a quick reference screen for crafting recipes, walkthroughs, or in-game maps.

Is It Worth It

Using your smartphone as a secondary gaming monitor is not the same as having a large external display, but it’s a budget-friendly solution. It makes multitasking smoother and improves convenience without buying new hardware. For gamers who want to maximize their current setup, it is definitely worth trying.
