Output to Multiple Monitors
Multiple monitors are also known as: second monitor, multi-monitors, right monitor, dual monitors, multi-display.
TouchDesigner can send video out to multiple projectors, monitors and recorders. TouchDesigner can run single-monitor or across many monitors.
Laptops all have different multi-monitor capabilities based on the manufacturer's specifications. Sometimes a laptop will have many output connections but still have limitations on the number of monitors it can drive simultaneously. Refer to the specifications for your specific laptop to understand its capabilities.
Spanning Monitors for Best Performance
TouchDesigner will run fastest in Perform Mode if you combine all your panels into one canvas that spans across all your monitors. This can be done easily with Container COMPs, then by assigning this to the Window COMP that is set for Perform Mode in the Window Placement Dialog. Using multiple Window COMPs is not suggested, and will result in poor performance.

- On the Desktop background, rightclick -> Display Settings -> Multiple Displays -> Extend These Displays.
Combining Monitors into a Single Virtual Monitor Even Better Performance
If possible, you should also join your monitors together into a single virtual monitor using Nvidia Mosaic, Nvidia Surround or AMD EyeFinity.
- System Preferences -> Displays -> Arrangement -> Mirror Displays = Off.
To allow monitor spanning on macOS, make sure the following is also set
- System Preferences -> Mission Control -> Displays have separate Spaces = Off
Additional Setup Tips
- Window Placement Dialog can be used to quickly assign Perform mode to different Window COMPs, and adjust parameters, jump to the network, and open/close the windows.
- Perform Mode can be turned On and Off with the Shortcut keys F1 (On) and Esc (Off).
- The Always on Top parameter in the Window COMP forces TouchDesigner to always be the top-most visible window.
