Windows Multi-Monitor Configuration + RustDesk Auto-Switch

This repo provides:

• display_config.bat — Predefined monitor layouts using NirSoft MultiMonitorTool.
• RustDeskWatcher.ps1 — A PowerShell script that tails RustDesk server logs and triggers monitor configs automatically:
  • On RustDesk connect → display_config.bat config2
  • On RustDesk disconnect → display_config.bat config1
• RustDeskWatcherTask.xml — Importable Scheduled Task that runs the watcher at boot.

---

🚀 Features

• Quickly switch between monitor configs from the menu or command-line.
• Auto-switch layout when RustDesk sessions start/end.
• Lightweight, no external dependencies beyond MultiMonitorTool + PowerShell.

🔧 Configurations

display_config.bat defines 4 monitor layouts:

1. config1 — All monitors (restores baseline)
2. config2 — Only Monitor 3 at 1680×1050
3. config3 — Monitor 1 + 3 only
4. config4 — Only Monitor 3 at 1920×1080

Run directly from the command line:

display_config.bat config1
display_config.bat config2
display_config.bat config3
display_config.bat config4

Run with no arguments to get an interactive menu.

🛠 Deploy RustDesk Auto-Switch

1. Place files

Copy these into:

C:\Users\mail\Documents\000 Development\Three monitor switch

• display_config.bat
• MultiMonitorTool.exe
• RustDeskWatcher.ps1
• RustDeskWatcherTask.xml

2. Import the task

Open an Admin PowerShell or CMD:

schtasks /Create /TN "RustDeskWatcher" /XML "C:\Users\mail\Documents\000 Development\Three monitor switch\RustDeskWatcherTask.xml" /F

Start it immediately (without reboot):

schtasks /Run /TN "RustDeskWatcher"

3. Test

• Connect via RustDesk → layout switches to config2.
• Disconnect → layout reverts to config1.

Logs are written to:

RustDeskWatcher.log

---

🔍 Detection Markers

The watcher looks for these strings in RustDesk logs:

• Connect: Connection opened
• Disconnect: Connection closed

If your RustDesk version uses different wording, update $ConnectRegex / $DisconnectRegex in RustDeskWatcher.ps1.

---

🛠 Troubleshooting

• Error SUBSCRIBER_EXISTS → The script is already running. Use Task Scheduler instead of starting it twice manually.
• MultiMonitorTool.exe not found → Place it in the same folder as display_config.bat.
• Different monitor IDs → Dump your mapping:

MultiMonitorTool.exe /stext monitors.txt

Update \\.\DISPLAYx in the batch file accordingly.
