How to Use Your Monitor Connected to Your Cellphone to Get a Bigger Screen

by Mandy Slake

Most cellular phones do not have the option for displaying the phone's screen on an external monitor because they lack a video outport. Recently some smartphones have appeared with HDMI capability. The iPhone uses a proprietary video cable that connects to the dock port, while Android phones use a micro HDMI to HDMI cable. Depending on the phone, you may need to purchase a separate cable. Some of these devices can mirror the entire screen, while others only play pictures or video from specific applications. Check with the manufacturer for details on your device.

IPhone HDMI

1

Connect the Apple Digital TV Adapter to the port on the bottom edge of your iPhone.

2

Plug one end of the HDMI cable into the HDMI port on the adapter. Plug the other end into the television.

3

Connect the AC adapter or data cable into the input port on the adapter. This step is not necessary for playing back video, but does ensure your iPhone does not drain the battery while it is connected to the monitor.

4

Open an application that supports HDMI playback.

Android HDMI

1

Locate the HDMI output port on the phone. This port is slightly smaller than the power/data port, and is usually located on the left or right side of the device.

2

Plug the small end of the micro HDMI to HDMI cable into the output port on the phone.

3

Connect the other end of the cable to the HDMI input on your monitor.

4

Enable the HDMI output in the phone's menus. HDMI output is an add-on feature not built into the Android operating system. Each manufacturer has their own method of enabling the port. Check your phone's manual for specific details on your device.

5

Open an application on the phone that supports video out.

Tip

  • check On devices that only support HDMI output on certain applications, the monitor screen will remain blank until you open a supported app on the phone.
