Most modern household and commercial projectors support wired network connection, which is a basic and practical network function for intelligent projectors, effectively making up for the instability of wireless WiFi connection. Many users only use WiFi to connect projectors to the network in daily use, but ignore the advantages of wired network. Wired network connection can provide more stable network transmission, lower delay and stronger anti-interference ability, which is very important for high-definition video streaming, online movie watching, large-file projection and game screen transmission, and is widely used in home living rooms and office scenarios.

Intelligent projectors launched in recent years are basically equipped with independent RJ45 wired network interface on the body, which can be directly connected to home routers or optical modems through network cables to realize wired networking. After connecting the wired network, the projector can stably access the network, complete online video playback, system upgrade, software download and cloud screen projection. Compared with wireless WiFi, wired connection is not affected by wall occlusion, device signal interference and WiFi bandwidth occupation, and the network speed is more stable, without frame drop, stuttering and disconnection during long-term high-bit-rate video playback.

For some old-style ordinary projectors without built-in wired network ports, users can also realize wired network connection through auxiliary equipment. The most common method is to use a network adapter or a wired screen projection box. Connect the network cable to the adapter first, and then connect the adapter to the projector’s HDMI or USB interface, so as to convert wired network signals for the projector to use. In addition, some portable mini projectors with simplified configuration do not have wired network ports, which are mainly oriented to mobile portable scenarios, and can only rely on wireless WiFi and hotspot networking, but such products are few in household large-screen projectors.

Using wired network for projectors has obvious practical advantages in home use. When multiple household devices are connected to WiFi at the same time, the wireless network bandwidth will be crowded, resulting in slow projector network speed and blurred online video images. Wired independent network transmission can completely avoid this problem, ensuring 4K ultra-clear video smooth playback and zero-delay screen projection of mobile phones and computers. Therefore, for families who pursue stable viewing effects, it is recommended to prioritize wired network connection when the network cable layout is reserved in the living room.
