Yes, you can use USB to connect to a projector, but the process depends on your projector’s capabilities and the device you’re connecting. Many modern projectors support USB media playback, presentations, and even direct screen mirroring from laptops, tablets, or smartphones. However, not all USB ports on projectors function the same way—some are for power only, while others can read files or stream content.
Connecting via USB is often a convenient alternative to HDMI or VGA, especially if your device lacks traditional display ports. USB-C-enabled laptops, for example, can transmit both video and audio signals directly to compatible projectors, making setup fast and reducing cable clutter.
