UGREEN HDMI 1 In 2 Out Splitter – UG-40201UK

The UGREEN UG-40201UK is a powered HDMI splitter that duplicates one HDMI source signal to two displays simultaneously. This compact device mirrors identical content across two monitors, projectors, or TVs while maintaining signal quality. Ideal for students presenting to dual classroom displays and businesses running synchronized content in meeting rooms, small retail spaces, or dual-monitor presentation setups.

Key Features & Benefits

• 1×2 Distribution Design: Connects one laptop, media player, or gaming console to two displays at once, eliminating cable swapping during presentations or enabling mirrored content in compact spaces.
• 4K Resolution Support: Delivers crisp image quality up to 4K @ 30Hz (3840×2160) on both outputs simultaneously, ensuring professional presentations and digital signage maintain visual clarity without compression artifacts.
• HDCP 1.4 Compliant: Passes through copy-protected content from streaming devices, set-top boxes, and Blu-ray players to both displays, allowing legal playback of commercial video without compatibility errors.
• Active Signal Amplification: Built-in powered amplifier with external adapter ensures stable output to both displays even with HDMI cable runs up to 15 meters, preventing signal dropout common with passive splitters.
• Zero-Configuration Setup: Works immediately without drivers or software installation—connect your source device, attach both displays, power on the unit, and start displaying within seconds.

Use Cases & Applications

Classroom Presentations: Connect one teaching laptop to both a main projector and a confidence monitor on the instructor’s desk. The UGREEN UG-40201UK lets teachers see their presentation content while students view it on the main screen, improving lecture flow and timing.

Small Meeting Rooms: Display presentation content on two wall-mounted TVs positioned at opposite ends of a conference table. This dual-screen setup ensures all meeting participants have clear sightlines regardless of seating position in narrow rooms.

Retail Point-of-Sale: Show promotional content or pricing information on two customer-facing displays from a single media player. The synchronized output reduces equipment costs and simplifies content updates—change one source to update both screens simultaneously.

Home Office Video Calls: Mirror your computer display to a second monitor or TV during virtual presentations. This setup lets you maintain eye contact with your webcam while viewing notes or slides on a secondary display positioned beside it.

Gaming Tournaments: Duplicate console gameplay to both a player’s monitor and a spectator screen or projector. Tournament organizers can broadcast matches to audiences while competitors play on their preferred displays.

Lecture Recording: Send presentation content to both a classroom projector and a video capture device simultaneously. This configuration enables professors to record lectures showing slides clearly without requiring separate screen capture software.

Restaurant Menu Boards: Display the same menu content on two screens positioned at different ordering counter locations. The mirrored output ensures customers see consistent pricing and offerings regardless of which line they join.

Portable Presentation Kit: Business professionals can pack the compact splitter for client meetings where dual-display setups improve presentation impact. The small form factor fits easily in laptop bags alongside other presentation equipment.

Live Event Production: Duplicate presenter slides to both a main auditorium screen and a backstage monitor. Event coordinators can track presentation progress without disturbing speakers or attendees.

Important Operational Notes: This is a splitter, not a switch—both outputs display identical content from the single input simultaneously. You cannot show different content on each display or select between multiple source devices without unplugging cables. The splitter requires external power via the included adapter and will not function on bus power alone, unlike some passive splitters that work without electricity but offer no signal amplification.

For optimal 4K performance, use high-quality HDMI cables rated for 18 Gbps transmission and keep total cable runs under 15 meters per output. The output resolution automatically matches the lowest common resolution among connected displays—if one monitor only supports 1080p while the other supports 4K, both outputs will downscale to 1080p to maintain compatibility.

HDCP-protected content (streaming services, Blu-rays, cable TV) requires both connected displays to support HDCP 1.4 or higher. Older non-compliant monitors or projectors may show blank screens or “HDCP error” messages when displaying protected content. The metal housing provides heat dissipation during operation and may feel warm after extended use, which is normal for powered electronic devices—ensure adequate ventilation around the unit and avoid blocking air circulation.

What This Splitter Does NOT Do: It does not function as an HDMI switch to alternate between multiple source devices—only one input is available. It does not extend displays as separate screens (extended desktop mode)—both outputs show identical mirrored content. It does not upscale lower-resolution sources to 4K or convert video formats. It does not support daisy-chaining to create more than two outputs. For switching between multiple HDMI sources, consider an HDMI switch instead. For extending desktop workspace across multiple monitors with different content, use your computer’s native multi-display outputs or a USB display adapter.
