🧠📽️ DVI • M1 (P+D) Cable

This cable connects a DVI-D output from a computer or media device to a projector or display with an M1-D (P&D) input. It’s used to transmit high-resolution digital video in legacy AV setups, especially in classrooms and conference rooms.
 
🔧 Cable Format & Use Case
🔌 DVI-D Male → M1-D (P&D) Male
DVI-D plugs into desktop GPU, laptop dock, or media player
M1 plugs into projector’s M1-D input port
Use Case: Direct cable connection for digital video from DVI source to M1-equipped projector
 
🖥️ Compatible Devices
💻 Desktop PCs and laptops with DVI-D output
📽️ Projectors with M1-D (P&D) input (InFocus, Dell, ASK Proxima, Toshiba, ViewSonic)
🧠 Embedded AV systems using M1-style signal routing
🏫 Classroom carts and legacy conference room setups
 
✅ Common Uses
🎥 Present from DVI-equipped laptop or PC to M1 projector
🧠 Bridge digital AV sources to legacy display infrastructure
🛠️ Enable DVI playback in older boardroom or classroom setups
📦 Simplify cable runs—no adapter needed
🧪 Test legacy projectors using modern DVI sources
 
🧠 Signal Format Notes
⚙️ DVI-D: Digital video only—no analog pins used
🔌 M1-D (P&D): 29-pin connector supporting DVI-D, VGA, and USB (this cable uses DVI-D path)
🔁 Cable uses DVI-D compatibility within M1 to carry digital video
🔊 Audio not supported—M1 does not carry sound
📉 Max resolution typically 1080p depending on projector capability
 
⚠️ Things to Watch Out For
🚫 No audio passthrough—requires separate audio cable if needed
🔌 Cable is directional—DVI source → M1 projector only
🧯 Not compatible with M1 (EVC) shell variants—check connector shape
📉 Some projectors may require manual input selection or resolution matching
🧪 May not support HDCP—check compatibility for protected content
 
🛠️ Quick Tips for Beginners
🧠 Identify M1-D (P&D) by its wide rectangular 29-pin layout
🔍 Use high-quality DVI cables to avoid signal degradation
🧼 Clean M1 contacts gently—dust can cause flickering or sync issues
🏷️ Label clearly—M1 cables are rare and easily confused with DVI
🎨 Use in legacy AV setups where DVI needs to meet old projector standards
