🧠📺 DVI • VGA Splitter

This adapter splits a single analog DVI-I signal into two VGA outputs. It’s ideal for duplicating content across two legacy monitors or projectors, especially in environments where synchronized visuals are key.
 
🔧 Adapter Format & Use Case
🔌 DVI-I Male → Dual VGA Female
Splits one analog video signal into two VGA outputs
Use Case: Mirror a single DVI-I source to two VGA displays simultaneously
 
🖥️ Compatible Devices
💻 Desktop PCs or laptops with DVI-I output (24+5 pin layout)
📺 VGA monitors, projectors, industrial panels
🏫 Classroom, kiosk, or training setups with mirrored displays
🧠 Diagnostic stations or legacy AV rigs
 
✅ Common Uses
🧠 Mirror PC output to two VGA monitors for presentations or signage
🏪 Display identical content on dual screens in retail or kiosk setups
🧯 Connect legacy VGA displays to a single DVI-I source
🛠️ Split analog video signal for testing or duplication
🎮 Use with older graphics cards that support DVI-I analog output
 
🧠 Signal Format Notes
⚙️ DVI-I: Integrated analog + digital; this splitter uses the analog pins
📡 VGA: Analog RGBHV video only—no audio
🔁 Passive splitter—no signal conversion or amplification
📉 Both VGA displays must support same resolution and refresh rate
🔇 No audio support—VGA is video-only
 
⚠️ Things to Watch Out For
🚫 Not compatible with DVI-D (digital-only) ports—requires DVI-I
📉 Only one VGA output may work reliably depending on GPU power
🧯 Not suitable for extending desktop or dual independent displays
🧪 May require manual resolution matching on both monitors
🔌 No HDCP support—won’t work with protected content
 
🛠️ Quick Tips for Beginners
🧠 Confirm your DVI port is DVI-I (look for 24+5 pin layout)
📏 Keep VGA cable runs short to avoid analog signal degradation
🧲 Use gold-plated connectors for better contact and durability
🏷️ Label outputs clearly in multi-monitor setups
🔍 Test with one monitor first before adding second to verify compatibility
