Using a Projector Without Wi-Fi: What You Need
A laptop, game console, or media player can send video to a projector through a compatible wired connection, so the projector itself does not need to join a Wi-Fi network. Before you settle in, match the device’s output to the projector’s input, select that input on the projector, and make sure the video you want to watch is available without internet access.
Downloaded movies, saved presentations, and locally stored photos can work well when you are traveling, giving a presentation, or setting up a movie night where Wi-Fi is unreliable. Download content ahead of time, then test playback before you leave home: some streaming apps require an internet connection to start a title, renew a download, or verify your account even when the video is saved.

Wi-Fi generally matters when you want to stream from an online service, use an internet-based app, or connect devices wirelessly over a network; it is not a basic requirement for projecting an image. Our guide to the 4K Smart Mini Projector with 3D, Android OS, WiFi & Built-in Battery covers a model with Wi-Fi, but having Wi-Fi does not mean you must use it for every viewing session.
No, a projector does not have to be connected to Wi-Fi to display content from a compatible wired source. You will generally need internet access if the content or app you choose depends on online streaming.
A media player can send locally stored or previously downloaded content to a projector without Wi-Fi if the devices have a compatible connection. Live streaming from an online service still needs an internet connection, whether that connection uses Wi-Fi or another supported method.
