Use Cases & Applications

Classroom Presentations: Connect one teacher laptop to four monitors positioned around a large lecture hall. The UGREEN UG-40202UK ensures every student sees the same presentation content regardless of their seating position, eliminating blind spots in auditorium-style classrooms.

Conference Room Displays: Present from a single source to multiple displays during board meetings or client presentations. The splitter mirrors your laptop screen to TVs mounted at different viewing angles, ensuring all meeting participants see identical content without delay or synchronization issues.

Retail Digital Signage: Broadcast promotional content from one media player to four storefront displays simultaneously. This setup reduces equipment costs and simplifies content management—update one source to change messaging across all screens instantly.

Trade Show Booths: Display product demonstrations or marketing videos on multiple screens surrounding your booth space. The synchronized output creates an immersive viewing experience that attracts attendee attention from multiple approach angles.

Sports Bars & Restaurants: Show the same live sports broadcast or menu content across multiple TVs from a single cable box or streaming device. This eliminates subscription costs for multiple set-top boxes while ensuring consistent viewing experiences.

Training Facilities: Instructors can share demonstration videos or software tutorials to multiple workstation monitors simultaneously. Students at different lab stations see identical content without gathering around a single screen.

Church & House of Worship: Display lyrics, sermon notes, or announcements on multiple sanctuary screens from one computer. The splitter ensures congregation members in different seating sections see synchronized content during services.

Hotel Conference Spaces: Event coordinators can distribute presentation content to multiple displays in ballrooms or meeting rooms. The setup works for corporate events, weddings, or conferences requiring multi-screen visibility.

Important Operational Notes: This is a splitter, not a switch—all four outputs display identical content from the single input simultaneously. You cannot show different content on each display or select between multiple source devices. The splitter requires external power via the included adapter; it will not function on bus power alone. For optimal 4K performance, use high-quality HDMI cables rated for 4K transmission and keep cable runs under 15 meters. The output resolution automatically matches the lowest common resolution among connected displays—if one display only supports 1080p, all outputs will downscale to 1080p. HDCP-protected content requires all connected displays to support HDCP 1.4; older non-compliant displays may show blank screens. The metal housing can become warm during extended operation, which is normal for powered splitters—ensure adequate ventilation around the unit.

What This Splitter Does NOT Do: It does not function as an HDMI switch to select between multiple sources. It does not extend wireless signals or convert to other video formats. It does not upscale lower-resolution content to 4K. For switching between multiple HDMI sources, consider an HDMI switch instead. For showing different content on each display, you need multiple video outputs from your computer or separate media players
