🧠🖥️ DVI • DVI Splitter

This splitter takes a single DVI-D output and sends the same digital video signal to two DVI-D displays. It’s used to mirror content across multiple screens—perfect for presentations, signage, or multi-monitor legacy setups.
 
🔧 Splitter Format & Use Case
🔌 DVI-D Male → 2× DVI-D Female
Male end plugs into source device (PC, GPU, media player)
Female ends connect to two DVI-D monitors or projectors
Use Case: Duplicate one video signal across two displays simultaneously
 
🖥️ Compatible Devices
💻 Desktop PCs and workstations with DVI-D output
📺 Monitors and projectors with DVI-D input
🧠 AV switchers and legacy control systems
🏫 Classroom carts, retail signage, and mirrored kiosks
 
✅ Common Uses
🧠 Mirror desktop display to second monitor for presentations
🛠️ Duplicate video signal for kiosk or signage setups
🎥 Send same content to projector and monitor simultaneously
🔁 Create mirrored control stations in legacy environments
🧪 Test multiple displays using one known-good DVI source
 
🧠 Signal Format Notes
⚙️ DVI-D: Digital video only—no analog or audio
🔁 Signal is duplicated—not extended or spanned
📉 Max resolution typically 1920×1200 @ 60Hz (depends on splitter quality)
🔌 Passive splitters may degrade signal—active splitters recommended for long runs
🧠 No HDCP handshake—may block protected content on some displays
 
⚠️ Things to Watch Out For
🚫 No audio passthrough—DVI does not carry sound
📉 Passive splitters may cause flickering or sync issues
🔌 Displays must support same resolution and refresh rate
🧯 Not for dual-monitor extension—only mirroring
🧪 Signal strength may drop—use powered splitter for long cable runs
 
🛠️ Quick Tips for Beginners
🧠 Identify DVI-D by flat pin layout—no analog cross pins
🔍 Use identical monitors for best results
🧼 Clean DVI ports gently—dust can cause signal loss
🏷️ Label splitter ends clearly—easy to confuse with DVI switch
🎨 Use in setups where mirrored video is needed, not extended desktop
