How to Connect Your iPhone to a Secondary Display

Share This:

If you’ve been looking for a way to take your iPhone experience to the next level, you’ll be thrilled to learn about secondary display options. With the right adapter, you can easily connect your iPhone to an external monitor or projector, giving you a larger and more immersive display experience. This is great for watching movies, playing video games, or just getting more work done on your iPhone.

The first thing you’ll need is an adapter that works with your device. For newer iPhones with a lightning port (iPhone 5 and later), you’ll need an Apple Lightning Digital AV Adapter. This adapter plugs into the lightning port on your device and provides an HDMI output. For older devices with a 30-pin dock connector (iPhone 4S and earlier), you’ll need a 30-pin Digital AV Adapter instead.

Once you have the adapter, simply plug it into your device and then connect it to the external display using an HDMI cable. You can also use VGA cables if your display supports them instead of HDMI cables. Once connected, open up the Settings app on your device and tap on “Display & Brightness” to configure the settings for the external display or projector.

You can now use the external display as if it were another monitor attached to your computer! You can move windows around between displays, watch movies or play games in full-screen mode, or even use AirPlay Mirroring to mirror what is happening on one screen onto another! The possibilities are endless!

Using an external display with your iPhone is a great way to get more out of your device and make tasks easier than ever before! Whether you want to watch movies in greater detail or do some work from home without having to lug around a laptop, connecting an external display will help make things simpler and more enjoyable.

How to Connect Your iPhone to a Secondary Display 1

Activating a Secondary Display on an iPhone

To turn on the secondary display on your iPhone, go to Settings > Display & Brightness. From there, tap “Duplicate” and then select the device you want to use as your secondary display. You can choose from AirPlay devices such as Apple TV or a Mac computer connected to the same Wi-Fi network. Once selected, the display will be mirrored on both screens.

Using an iPhone as a Projector

To use your iPhone as a projector, you’ll need an Apple Lightning Digital AV adapter. This adapter plugs into your device’s Lightning port and connects to a projector with an HDMI cable. Alternatively, if you’re using an older projector, you may need to use a Lightning to VGA adapter instead. Once everything is connected, your iPhone or iPad should show up on the projector’s display. You can then use your iOS device as a presentation tool or watch movies on the big screen.

Utilizing a Secondary Display

To use your secondary display, you’ll need to connect it to your computer. Depending on the type of display and graphics card you have, you may need a special cable or adapter. Once the display is connected, you’ll need to configure it in your operating system’s settings. On Windows 10, for example, you can open the Settings app and select System > Display. You can then select the new monitor from the list and choose how you’d like it to be used: either as an extended display or as a duplicate of your main screen.

The Purpose of Primary and Secondary on an iPhone

The primary and secondary feature of an iPhone allows you to use two different mobile phone plans on the same device. This means that you can have one plan for voice, SMS, and iMessage while having another plan strictly for cellular data. This is especially useful when traveling internationally, as it allows you to keep your domestic plan active while using a more cost-effective international plan for data. By using a primary and secondary setup, you can save money by taking advantage of different plans that may offer different rates and coverage in different areas.


In conclusion, connecting your iPhone to a secondary display can be a great way to make presentations or watch movies with friends. With the help of an original Apple Lightning Digital AV adapter and/or Lightning to VGA adapter, you can easily connect your iOS device to a projector or other display. Furthermore, having multiple Home screens on your iPhone allows you to store more apps than would fit on one page, making it even easier to access the content you want.
