In today's world of mobile technology, we often find ourselves viewing content on the small screens of our smartphones and tablets. However, there are times when it can be useful to mirror that content on a much larger display. Connecting your smartphone to a projector allows you to turn your small screen into a big one, ideal for giving presentations, sharing videos and photos with a group, or streaming movies and TV shows on a large projector screen.

In this blog post, we'll walk through the benefits of connecting your smartphone to a projector, the different options for wired and wireless connections, and tips for troubleshooting any issues that arise. We'll also include a FAQ at the end to cover some of the most common questions about smartphone-to-projector connections.

Project Your Phone to Amplify Experiences

There are several advantages to hooking your smartphone up to a projector:

Share content with a large group. Rather than crowding around your 5-7 inch smartphone screen, connecting your phone to a projector allows you to display content on a much larger projected image that everyone in the room can clearly see.

Business and presentations. For professionals and students who need to give presentations on the go, the ability to quickly connect a smartphone to a projector is extremely useful. It facilitates seamless, impromptu presentations in any setting with a projector, from conference rooms to classrooms. The large projected display ensures your entire audience can easily see and follow along with your presentation slides, graphs, videos, and any other content from your phone.

Watch movies and videos on a big screen. Connecting your smartphone to a projector essentially turns any blank wall into a big screen TV for watching movies, TV shows, sports, funny viral videos, and more. It provides a theater-like viewing experience anywhere there is a projector available, for personal entertainment or for groups.

Display photos and slideshows on a large-scale. Hooking a smartphone up to a projector allows you to easily share photos and slideshows with large groups. Family reunions, parties, events, and more are great opportunities to project your photos large-scale for everyone to enjoy together.

Play games on a big screen. Gaming on a smartphone is made more immersive and exciting when you mirror the gameplay onto a big projected screen. Racing, action, sports, and multiplayer games are especially fun when projected large for a group.

Show instructional videos and tutorials to a class or group. For teaching and training situations, projecting smartphone content is very useful for showing how-to videos, tutorials, lectures, demos, and other instructional visuals to students or trainees. The large display allows everyone to see clearly.

Wired Connection Options

Connecting your smartphone to a projector using a wired connection is relatively straightforward. All you need is the right adapter or cable to connect your specific smartphone model to the projector you're using. Here are the most common options:

HDMI Adapter

One of the most popular wired options is to use an HDMI adapter made specifically for your smartphone model. This connects to your smartphone's charging port to mirror its display in HD resolution. Most new Android devices and iPhones support HDMI output.

- Lightning to HDMI:
For iPhones and iPads, you can use a Lightning to HDMI cable. Simply plug the Lightning connector into your iOS device and connect the HDMI end to the projector port.

- USB-C to HDMI:
For USB-C equipped Android phones, a USB-C to HDMI adapter cable will allow you to connect to the projector's HDMI input. Most new Android phones use USB-C.

VGA Adapter

Some older projectors may only have a VGA input. In this case, you can get an adapter that connects from your smartphone's charging port to VGA. However, video quality will be lower than HDMI.

How to connect:
Identify the right cable. You'll need a cable that has connectors to match both your smartphone's port and the projector's input port.
Connect the cable. Plug one end into your smartphone's charging port. Plug the other end into the HDMI input port on your projector.
Configure your smartphone. Open your phone's Settings and navigate to the Display settings. Look for an option to enable video output through the connected cable port.
Switch the projector input. Turn on the projector and use its remote or menu system to switch its video input source over to the HDMI port you connected the phone cable to.
Mirror your phone's display. Your smartphone screen should now be mirrored and displayed through the projector! Open the photos, videos, or other content you want to share on the big screen.

Wireless Connection Options

If you don't want to deal with cables, there are a few ways to wirelessly connect your smartphone to a projector, offering convenience and flexibility:


One easy wireless option is using a Chromecast device. Just plug the Chromecast into the projector's HDMI port. You can then cast content from smartphone apps that support Chromecast, like YouTube, Netflix, Google Photos and more.


Many Android devices support Miracast, allowing you to wirelessly mirror your phone's display to the projector. Make sure the projector is Miracast compatible. Tap on the "Screen Mirroring" or similar option in your Android settings to connect.


For Apple users, AirPlay is the wireless mirroring protocol. As long as the projector is AirPlay compatible, you can mirror your iPhone or iPad's display to it wirelessly. Swipe down from the top right for the iOS control center and select "Screen Mirroring."


There are also various third-party apps like AirScreen and Google Home that allow wireless streaming from your smartphone to a projector. These may offer more functionality than the built-in options.

How to connect:
Verify projector compatibility. Your projector must have built-in support for wireless projection standards like AirPlay, Miracast, or Chromecast to connect wirelessly. Consult your projector specs and manual to confirm.
Enable wireless projection mode. Open your smartphone's Settings and locate the option for wireless or screen projection.
Connect to the projector. Your phone will scan and display any compatible projectors it finds nearby that are in projection mode. Select your projector from the list to connect.
Adjust projection settings. Your phone may prompt you to set display resolution and orientation. Set them appropriately for your content and the projector's resolution.
Project your smartphone display. Your smartphone screen contents should now display wirelessly through the projector! Play videos, display photos, or show any apps you like on the big screen.

Troubleshooting Tips

While connecting your smartphone to a projector is usually straightforward, issues can arise. Here are some quick troubleshooting tips:

- Check adapter/cable connections. Make sure all cables are plugged in properly on both ends.
- Try an alternate adapter or cable. Faulty cables are a common issue; try swapping for another.
- Check projector source input settings. Input may need to be changed to the port you connected the smartphone to.
- Adjust smartphone resolution. Sometimes matching smartphone and projector resolutions can fix issues.
- Restart devices. Power cycle the smartphone and projector, and try again.
- Update software/firmware. Outdated software versions can cause connectivity problems.
- Disable other wireless connections. Disconnect Bluetooth and other WiFi networks that interfere with wireless casting.

If problems persist, consult your device manuals or contact support for further troubleshooting assistance.


Connecting your smartphone to a projector opens up exciting possibilities for viewing, sharing, presenting, and more on a much larger display. With the right cables and adapters, HDMI and VGA wired connections allow you to directly mirror phone content to the projector.
