- Devices Android: Typically USB-C (most modern) or micro-USB, with support for MHL or SlimPort (this determines whether it can output video directly). To learn how to connect your phone to the projector via cable, also check out this guide.
- iPhone: They use the Lightning connector. Most recent models support video output via official adapters.
Always check the projector and mobile manual. to verify compatibility with video output features. In some cases, only certain models or operating system versions offer support for screen mirroring. Search the manufacturer's website or check your phone's settings menu to confirm these options.
Connecting your mobile phone to the projector via cable: step by step and alternatives
Connecting your mobile phone to the projector via cable is the most universal and stable solution to ensure image and sound transmission without interruptions or latency.There are different options depending on the operating system, the type of port on the phone, and the projector's inputs.
What cable do I need?
- Android: Typically, an MHL (Mobile High-Definition Link) or SlimPort adapter is used, connecting the phone's USB-C/microUSB port to the projector's HDMI port. Some newer Android phones also allow the use of direct USB-C to HDMI cables, provided the "Alt Mode" feature is supported. For more information, see .
- iPhone: They require an official Lightning to HDMI adapter (also called Apple's Digital AV Adapter) to connect directly to the projector.
For older devices or projectors with analog connections, microUSB/USB-C to VGA or RCA adapters are available, but quality and compatibility can vary considerably.
Steps to connect your mobile to the projector via cable
- Check that the mobile and the projector are compatible with the connection method you have chosen (refer to the manual of both devices).
- Turn off the projector before making connections to avoid synchronization failures or damage to the ports.
- Connect the cable or adapter to the mobile phone and to the projector (HDMI, USB-C, Lightning, etc. as appropriate).
- Turn on the projectorThe mobile image should automatically appear mirrored on the screen or wall. It may take a few seconds to sync.
- If the image does not appear: Go to your phone's display settings and look for the option for "External video output," "Secondary display," or "Screen mirroring." Activate it if available.
On most HDMI connections, the sound is transferred along with the image to the projector. However, many projectors have low-power built-in speakers, so it's advisable to connect an external sound bar or Bluetooth speakers to your phone to enhance the experience (see the "sound" section below).
If your phone doesn't support direct video output via cable, another solution is mirroring via a computer. There are programs like TeamViewer, ApowerMirror, MirrorOp, or AirDroid that allow you to project your phone's screen onto your PC, then connect the computer to the projector via HDMI/VGA. This technique is especially useful with older projectors or phones without MHL/SlimPort support.
