📽️🔌 Component • M1 (P+D) Cable

The Component • M1 cable connects projectors with an M1-DA port (also known as VESA Plug & Display) to devices that output analog component video. It translates the RGBHV or YPbPr signal from DVD players, DVRs, and AV receivers into a format compatible with select InFocus projectors and other legacy display gear.
 
🔧 Connector Breakdown
🔹 M1-DA (Source Side)
Form Factor: 30-pin DVI-style connector
Signal Type: Analog RGB or YPbPr + optional USB/serial
Found On: InFocus projectors (SP4805, SP5700, SP7205, X2, X3), some Dell and ViewSonic models
Note: Supports multiple signal types depending on device firmware
🔹 Component RCA (Output Side)
Form Factor: 3 RCA plugs (Red, Green, Blue)
Signal Type: YPbPr analog video
Connects To: DVD players, HDTV tuners, AV receivers
Note: No audio—video only
 
🖥️ Compatible Devices
📽️ InFocus projectors with M1-DA input
📀 DVD players with component output
📡 HDTV receivers and DVRs
🎮 Game consoles with YPbPr output (via breakout box)
🧱 AV switchers and distribution amps
 
✅ Common Uses
📺 Connect component video sources to M1-equipped projectors
🧩 Enable high-quality analog video playback in home theaters
🔄 Bridge legacy AV receivers to older display hardware
🧪 Test projector input modes with analog sources
🧼 Maintain compatibility in retro AV setups
 
🧠 Signal Format Notes
Signal Type: YPbPr analog component video
Resolution Support: Up to 1080i depending on projector
No Audio: Separate cable required for sound
Pin Mapping: M1-DA pins mapped to RCA color channels
Firmware Dependent: Some projectors require mode switching to accept component
 
⚠️ Things to Watch Out For
🔌 Not compatible with HDMI or DVI—analog only
📏 Cable length affects signal quality—keep under 30ft for best results
🧯 Some M1 ports require manual input selection for component mode
🔄 No EDID handshake—resolution must be manually set on source
🧪 Test with known-good source before permanent install
 
🛠️ Quick Tips for Beginners
🔍 Confirm your projector supports component via M1-DA
🧰 Use color-coded RCA plugs to match YPbPr layout
🧪 Set source resolution to 480p or 720p for compatibility
🧼 Route audio separately—use stereo RCA or optical
🔧 Secure M1 connector firmly—some models have locking tabs
