# Expanders VIOSO provides robust solutions for managing multi-projector setups by splitting the graphics card output according to the projector topology. This functionality is critical when using video signal expanders. **Video Signal Expanders:** * **Matrox**: DualHead2Go, TripleHead2Go, QuadHead2Go * **Datapath**: X4, FX4 * **Analog Way**: DPH104 **Switchers:** * Presentation switchers and video matrix switchers are also fully compatible, allowing for the expansion of projector connections from a single graphics output. #### Configuring Graphics Card Output with VIOSO VIOSO provides robust solutions for managing multi-projector setups by splitting the graphics card output according to the projector topology. To effectively utilize video signal expanders in conjunction with VIOSO, it's vital to correctly split the graphics card output. This ensures that each projector receives the intended portion of the video signal, resulting in a seamless multi-projector display. For detailed instructions on configuring your setup in either Free Mode or Project Mode, please refer to the appropriate documentation. This guidance will help you understand the specific steps required to match your projector topology with the graphics card output, ensuring optimal performance of your VIOSO calibration solutions. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
