You don’t need an expensive projector to enjoy your mobile screen on a big wall! Thanks to modern technology and a little bit of creativity, you can use these amazing methods to project your mobile screen in easy and exciting ways. Whether you enjoy wireless solutions or prefer good old-fashioned DIY, we’ve got you covered. Check out these five brilliant methods to bring your screen to life.
1. Wireless Screen Mirroring (Miracast)
Miracast is like a wireless wizard for your phone’s screen! With this technology, you can mirror your mobile screen onto a bigger display like a smart TV or monitor, no cables needed. First, check if both your phone and the device you’re projecting onto support Miracast. Then, head over to your phone settings and turn on the ‘Cast’ or ‘Screen Mirroring’ option.
Once you pair your device with the display, wohoo! Your screen will be mirrored wirelessly. It’s a super convenient way to enjoy your favorite movies, games, or videos on a large screen.
2. Utilizing A Versatile Streaming Device (Chromecast)
If you’re looking for an effortless way to mirror your phone, Google’s Chromecast is your best buddy. Plug the small Chromecast device into your TV’s HDMI port, connect it to Wi-Fi, and download the Google Home app on your mobile. With just a few taps, you can mirror your phone’s screen to your TV.
And you know what’s the cool part? Chromecast also lets you stream tons of apps and platforms like YouTube and Netflix, making it a fantastic multitasking tool for entertainment.
3. All Hail the HDMI Adapter
For those who want a direct connection, an HDMI adapter is the way to go. This method works perfectly if your phone has a USB-C or Lightning port (depending on your device model).
Here’s what to do:
Buy a USB-C to HDMI adapter for Android devices or a Lightning to HDMI adapter for iPhones. Connect your phone via the adapter, plug the HDMI cable into a monitor or TV, and you’re all set. This method is great for presentations or binge-watching sessions because it ensures a stable, high-quality connection without any lag.
4. Innovative Applications
Love apps? You’ll love this method! Screen mirroring apps like AirServer, ApowerMirror, and Reflector make it easy to cast your phone’s screen onto your computer or TV. Just download one of these apps on both your phone and the display device, connect them to the same Wi-Fi network, and start casting.
These apps often come with bonus features like recording your screen or adding annotations, which can be super useful for school projects or work presentations. Plus, they’re easy to use and compatible with most modern devices.
5. DIY Phone Projection
Feeling crafty? Making a DIY projector can be a fun weekend project! All you need is a shoebox, a magnifying glass, and some tape.
Cut a hole in the box and attach the magnifying glass securely. Then, place your phone inside the box, play a video, and adjust the focus with the magnifying glass to project the screen on your wall.

How To Make A DIY Projector To Project Mobile Screen?
Instead of buying expensive projectors, you can make your own with readily available materials at your home. Someone with a creative mind finds it fun and can add other things too. Before we start, gather the following items needed in the preparation.
- A Mobile phone
- Shoe box or any other rectangular box
- Magnifying Lens (Buy Here)
- Hot glue gun or tape
- X-acto precision knife
- Pencil
- Black paper
- Binder clips
- Paint
Now that you have all the items ready, it’s time to start creating your DIY projector. Follow these step-by-step instructions to turn your regular smartphone into a projector in 2025:
Step 1: Make a Circle in the Box
To begin, you need to create a hole for the magnifying glass. First, carefully cut the handle off the magnifying glass using a hand hacksaw. Then, place the magnifying glass flat on the shoe box (or rectangular box) and use a pencil to trace a circle around it.
Once you have your circle outline, use the X-acto knife to cut out the circle. Be precise so the magnifying glass fits perfectly into this hole.
Step 2: Cover the Interior of the Box
For the projector to work well, it’s important to stop light from reflecting inside the box. Take your black matte paper and cut it to the size of the box’s interior walls. Use glue to stick the paper inside the box, covering all the surfaces completely. If you don’t have black matte paper, you can use black paint instead, but remember it will take a little time to dry.
Step 3: Attach the Magnifying Glass
Now, take your prepared magnifying glass and place it into the circle you cut in Step 1. Use a hot glue gun or tape to secure it in the correct position. This lens will serve as the heart of your DIY projector by magnifying the light rays from your smartphone to create a larger image on the wall.
Step 4: Make a Stand for Your Mobile Phone
Your phone needs a stable stand inside the box. To make this, use a foam card or a piece of hardboard. Measure the dimensions of your box (length, width, and height) and cut the card to fit.
Next, measure your smartphone and ensure the stand allows your phone to rest vertically while fitting snugly in the box.
Attach the stand using a glue gun or binder clips, and for extra support, you can use double-sided tape to secure your smartphone on the stand.
Step 5: Adjust Your Smartphone Settings
Before you use your DIY projector, tweak some settings on your smartphone. Turn off the auto-rotate option so the image doesn’t shift, and increase the brightness to its maximum for better projection quality. If you have a Bluetooth speaker, connect it to your phone for louder sound, giving you a more immersive cinematic experience.

Step 6: Install the Mirror
This step is essential to fix the image orientation. Without a mirror, the projection on the wall will appear inverted. Take a clean mirror and place it at a 45-degree angle inside the box, opposite the lens. This will ensure your projected image or video is displayed correctly. Adjust the mirror until the projection looks perfect on the wall.
Step 7: Add Decorations
Congratulations! Your DIY projector is ready to use. To make it look even more fun and stylish, feel free to add some final touches. Paint the box with your favorite colors, draw cool designs, or stick on creative decals. A beautifully decorated projector will add a touch of personality and make your homemade gadget even more impressive.
Enjoy your new DIY projector and watch your favorite videos or images come to life on your wall like never before!
How Does A DIY Projector Work?
In this handmade projector, the smartphone is placed on the stand, and the box lid is closed so no light from the outside can affect the image quality. Light from the mobile screen is passed to the magnifying glass, which will project a larger image on the wall.
The interior of the box must be black to avoid light reflection. The image quality from this DIY projector will not be the same as other electronic projectors with amazing features to enhance the image quality.
Things To Keep In Mind To Enhance The Image Quality
If you want to get the phone screen on the wall with the best image quality, keep in mind the following things:
- Increase the brightness of the mobile to its highest level. So, the image will be brighter and visible with better quality.
- Ensure that light can’t enter the box and that the material used inside the box must not reflect the light. It will affect the image quality.
- If the image is not visible or blurry, try to move the projector nearer or closer to the wall.
- Ensure that the box is placed at a significant height and distance from the wall.
How Can I Project My Phone Screen On The Wall With A Projector App?
For those who want to project their mobile phone’s screen onto a wall with a projector app, here’s what to do:
Step 1. Download and Install the Projector App
Search your app store for a projector app that suits your needs. Download and install the app on your mobile device. Make sure to read through the app description and reviews to confirm compatibility with your device and requirements.
Step 2. Set Up a Shared Wi-Fi Connection
Both your mobile device and the external display device, such as Chromecast or Roku, need to be connected to the same Wi-Fi network. This is essential for them to communicate with each other. If they are not already on the same network, go to the Wi-Fi settings on each device and select the same network.
Step 3. Open the Projector App
Once installed, launch the projector app on your phone. The app will often guide you through the process with simple on-screen instructions. Follow the prompts carefully to ensure the app is set up correctly.
Step 4. Connect to the External Display
Using the app, connect your mobile device to the external display. The app will usually search for nearby compatible devices. Select your external device (like Chromecast or Roku) from the list when it appears. Confirm the connection, and ensure there are no interruptions during this process.
Step 5. Project Mobile Screen on the Wall
After the connection is made, your mobile screen should now appear on the wall through the external display. The external device acts as the bridge between your mobile and the wall projection, enabling a seamless viewing experience.
Step 6. Customize the Display
Most projector apps offer features like adjusting the aspect ratio, zooming in or out, or even enhancing brightness. Explore the app’s options to make the screen display exactly as you want it. For a better viewing experience, ensure the room is dimly lit and the wall is clean and flat.
