What it does
TruckDeck Multimon writes ETS2/ATS multi-monitor config for you —
multimon_config.sii and patches config.cfg
(r_multimon_mode / resolution) — so you can run
stacked dual, Picture-in-Picture on MAIN, and more without hand-editing files.
- Bundled with TruckDeck 1.6.6.43 — launch from TruckDeck or the Start menu
- Multimon 1.2.0.8 — PiP on MAIN can be turned off; per-screen surround FOV
- Left window is always left, right is always right (physical layout)
- Built-in presets (dual, triple, quad, five, six-surround, stacked layouts)
- PiP on MAIN — side cameras on your primary monitor at native resolution
- Windows 10/11 · .NET Framework 4.8
What is Picture-in-Picture (PiP)?
PiP means Picture-in-Picture
— an extra camera view drawn as a panel on top of your main driving view.
PiP on MAIN
The game stays at your MAIN monitor’s native resolution.
Center cabin fills MAIN; left/right/mirror views are inset panels on that same screen.
Full-span dual (not PiP)
Classic stacked layout: bottom monitor = center road view, top monitor = split side windows.
The game window spans the whole Windows desktop.
Quick start
- Install TruckDeck 1.6.6.43 from the downloads page.
- Launch Multimon from the TruckDeck window or Start menu.
- Close ETS2/ATS before Apply (blocked while the game is open).
- Pick a preset or PiP on MAIN → adjust cameras → Apply & Launch.
