One of the simplest methods to display videos, presentations, images, or even mobile games on a large screen is to connect your phone to a projector via USB. This guide covers everything you need to know, whether you're getting ready for a business meeting or organizing a movie night at home.
Can You Connect a Phone to a Projector via USB?
In a nutshell, the answer is yes — but it depends on your projector and phone.
Three Typical USB Connection Situations:
-
USB-C with DisplayPort Alt Mode
(Most contemporary Android phones support this.) -
USB-C with HDMI Adapter
(Preferred and most reliable method.) -
USB-A to USB-A
(Supports file transfer only — no screen mirroring.)
⚠️ Direct screen mirroring with a typical USB-A cable is not supported by the majority of projectors. Usually, you'll need a USB-C to HDMI hub or adapter instead.
What You Need Before Connecting
To use USB to connect your phone to a projector, make sure:
-
✔ Your phone supports USB-C video output (DisplayPort Alt Mode)
-
✔ The projector has an HDMI port
-
✔ You have a USB-C to HDMI adapter or USB-C hub
If your phone can only charge and transfer data — but not output video — a USB connection won’t mirror your screen.

Why HDMI Is Better Than Direct USB
Many consumers believe that their phone's screen may be mirrored with a straightforward USB-A to USB-A cable, but this is rarely the case.
HDMI Provides:
-
Greater clarity (up to 4K)
-
Reduced latency
-
Consistent video signal
-
All-around compatibility
USB-A Ports on Projectors Are Usually Designed For:
-
Playback of flash drives
-
Firmware updates
-
Access to media files
❌ Not screen mirroring in real time.
Troubleshooting: Phone Not Connecting to Projector via USB?
If your screen is not visible:
1. Verify Support for USB-C Video
Video output is not supported by every USB-C port.
2. Verify the Projector Input
Change the HDMI input to the appropriate one.
3. Try a Different HDMI Cable
Cable problems are frequent.
4. Restart Devices
Restart both the projector and phone.
5. Update Your Device
Make sure the OS on your phone is current.
