By: David Bowdler
Updated: June 14, 2026
Version: 2.00
Samsung MDC Multi-Display
Control up to eight Samsung commercial and signage displays from a single RTI driver instance using the Samsung MDC (Multiple Display Control) protocol — over TCP/IP (port 1515) or RS-232 (9600 8N1). Add a display source per room, or run a whole video wall from one processor.
Key Features
- Up to 8 displays - each with its own IP / port / Display ID; control independently or all at once.
- Two-way feedback - power, volume & mute, input, picture & sound mode, brightness/contrast/sharpness, model/serial/firmware.
- Health monitoring - per-panel temperature with a configurable over-temperature event, plus fan and lamp error flags.
- Management - Safety Lock (lock all keys), Remote-IR enable/disable, Auto Power, Network Standby.
- Video Wall - on/off, Full/Natural, layout & position, broadcast all-on/off.
- Mass & targeted control - All Displays power/mute/input, per-display targeting, Select Display.
- Browse menu, debug console, optional cloud logging, and a Cable/Satellite TV template (keypad / channel / transport on tuner-equipped models).
Requirements
- RTI XP processor - runtime 24+, software / Apex 11.4+.
- Samsung commercial display with MDC support (QET, QBT, QMT, QHT and similar SMART Signage).
- Display on the network (TCP port 1515) or connected via RS-232 (9600 8N1).
How It Works
Set the number of displays and each display's IP and Display ID in the configuration, then add a Display source to each room. A 120-minute trial is included so you can verify compatibility before licensing.
Samsung MDC Multi-Display Driver v2.00

2. Note the display's IP address (Home > Network > Network Status)
3. Set Display ID if needed (Home > ID Settings > Set Display ID)
4. Enter the IP address in driver config. Default port is 1515.
RS-232 Serial:

Number Pad, Channel & Transport Buttons
The number pad (0-9), Channel Up/Down, Guide, and the transport keys (Play, Pause, Stop, Rewind, Fast Forward, Record) are sent to the display as virtual remote-control key commands (MDC command 0xB0). These functions require a model that has a built-in TV tuner / media playback.
Important - tested model: The display used for testing was a Samsung QET-series signage panel (QE65T), which has NO TV tuner. These specific commands are accepted by the panel (the command is valid and acknowledged) but have no visible effect on a tuner-less signage display - this is expected. On Samsung commercial TVs that DO include a tuner, they pass through and operate normally.
If you use these buttons on a different model and they do not work as expected, please let us know at david@smarthomeprogramming.com.au and we will look into it further.
Multiple Displays
Set "Number of Displays" (1-8) in the configuration, then fill in each display's Name, IP Address, TCP Port and Display ID. Add a Display source to each room where a screen lives. Control functions can target a specific display via the Display parameter, or the currently selected display. Use "Select Display" to change the selected display.
Browse Menu
The browse menu provides quick access to common settings with visual icons. Categories can be enabled/disabled in the Browse Menu config section. Active items are marked with a checkmark.
Debug Console
Connect via telnet to the debug port (default 12513) for live diagnostics. Type 'help' for available commands.
Display ID
When daisy-chaining multiple displays via RS-232, each display needs a unique ID (1-254). Use ID 0 for direct single-display connection. ID 254 (0xFE) broadcasts to all displays.
