🧠📽️ DVI + USB • M1 (P+D) Cable
This cable combines a DVI-D connector for digital video and a USB-A connector for control/data, merging both into a single M1-D (P&D) plug. It’s used to connect PCs or media players to projectors that support video and USB input via M1.
🔧 Cable Format & Use Case
- 🔌 DVI-D Male + USB-A Male → M1-D (P&D) Male
- DVI-D transmits digital video
- USB-A enables control features (e.g. wireless presenter, mouse emulation)
- M1-D plugs into projector’s input port
- Use Case: Deliver video and USB control to M1-equipped projectors using one cable
🖥️ Compatible Devices
- 💻 Desktop PCs and laptops with DVI-D and USB-A outputs
- 📽️ Projectors with M1-D (P&D) input (Infocus, Dell, Toshiba, ViewSonic, ASK Proxima)
- 🧠 AV carts and classroom setups using wireless presenters
- 🛠️ Embedded systems requiring combined video/control routing
✅ Common Uses
- 🎥 Present from PC to projector with video and USB control
- 🧠 Enable wireless presenter or mouse control via USB passthrough
- 🛠️ Simplify cable runs—one cable for both video and control
- 🏫 Classroom and conference room AV setups
- 🧪 Test legacy projectors with integrated DVI + USB input
🧠 Signal Format Notes
- ⚙️ DVI-D: Digital video only—no analog pins used
- 🔌 USB-A: Standard USB 2.0 for control/data
- 📡 M1-D (P&D): 29-pin connector supporting DVI-D, VGA, USB
- 🔊 No audio support—M1 does not carry sound
- 📉 Resolution support typically up to 1080p depending on projector capability
⚠️ Things to Watch Out For
- 🚫 Not compatible with HDMI or analog VGA without active conversion
- 🔌 USB must be connected for control features to work
- 🧯 Some projectors require manual input selection or driver support
- 📉 No HDCP support—may block protected content
- 🧪 Cable length affects USB reliability—keep under 10 ft for best performance
🛠️ Quick Tips for Beginners
- 🧠 Identify M1-D (P&D) by its wide rectangular 29-pin layout
- 🔍 Confirm your projector supports USB control via M1
- 🧼 Clean M1 contacts gently—dust can cause flickering or sync issues
- 🏷️ Label both ends—USB and DVI often get tangled in AV setups
- 🎨 Use in legacy AV environments where combined control and video are needed
