🧠📽️ HDMI • M1 (P&D) Cable

This cable connects a modern HDMI source directly to a projector or display with an M1-D (P&D) input. It’s designed to carry high-definition digital video from laptops, media players, or embedded systems into legacy AV environments.
 
🔧 Cable Format & Use Case
🔌 HDMI Male → M1-D (P&D) Male
HDMI plugs into laptops, desktops, consoles, or media players
M1 plugs into projectors with P&D-style M1-D input
Use Case: Direct cable connection for presentations, classrooms, and embedded AV rigs
 
🖥️ Compatible Devices
💻 HDMI laptops, desktops, media players
📽️ Projectors with M1-D (P&D) input (InFocus, Dell, ASK Proxima, Toshiba, ViewSonic)
🧠 Embedded AV systems using M1-style signal routing
🏫 Classroom carts and conference room setups with legacy projectors
 
✅ Common Uses
🎥 Present from HDMI laptop to M1-equipped projector
🧠 Bridge modern AV sources to legacy display infrastructure
🛠️ Enable HDMI playback in older boardroom or classroom setups
📦 Simplify cable runs—no adapter needed
🧪 Test legacy projectors using modern HDMI sources
 
🧠 Signal Format Notes
⚙️ HDMI: Digital video + audio (Type A)
🔌 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 HDMI 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—HDMI 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 HDMI 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 HDMI needs to meet old projector standards
