🧠🔌 DVI • M1 (P+D) Adapter
This adapter allows a projector with an M1-D (P&D) input to accept a standard DVI-D cable. It’s used when the projector has an M1 port but the source device uses DVI-D—ideal for retrofitting modern sources into older AV environments.
🔧 Adapter Format & Use Case
- 🔌 M1-D (P&D) Male → DVI-D Female
- M1 plugs into projector’s input port
- DVI-D cable plugs into adapter’s female end
- Use Case: Connect modern DVI-D source to legacy projector using standard DVI cable
🖥️ Compatible Devices
- 📽️ Projectors with M1-D (P&D) input (Infocus, Dell, Toshiba, ViewSonic, ASK Proxima)
- 💻 PCs, laptops, and media players with DVI-D output
- 🧠 AV carts and legacy classroom setups using modular adapters
- 🛠️ AV integrators needing flexible projector-side solutions
✅ Common Uses
- 🧠 Retrofit legacy projectors to accept DVI-D signal
- 🛠️ Use standard DVI cable instead of rare M1-to-DVI cables
- 🎥 Enable presentations from modern laptops to older projectors
- 🔁 Swap adapter between projectors for flexible AV routing
- 🧪 Troubleshoot M1 projector inputs using known-good DVI sources
🧠 Signal Format Notes
- ⚙️ DVI-D: Digital video only—no analog or audio
- 🔌 M1-D (P&D): 29-pin connector supporting DVI-D, VGA, and USB (adapter uses DVI-D path only)
- 🔊 No audio support—M1 does not carry sound
- 📉 Resolution support depends on projector’s internal scaler (typically up to 1080p)
⚠️ Things to Watch Out For
- 🚫 No audio passthrough—requires separate audio cable
- 🔌 Adapter is directional—M1 projector input only
- 🧯 Not compatible with M1 (EVC) shell variants—check connector shape
- 📉 Some projectors may require manual input selection or resolution matching
- 🧪 Adapter 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 adapter clearly—easy to confuse with VGA or USB variants
- 🎨 Use in legacy AV setups where projector has M1 input but source uses DVI
