# Graphics cards The GPU (Graphics Processing Unit) plays a crucial role in multi-projector setups, particularly in workstations, media servers, or multimedia PCs, where the primary objective is to drive multiple displays seamlessly. Professional GPUs from NVIDIA (such as the Quadro/RTX range) and AMD (including the Radeon PRO lineup) are preferred for such applications due to their superior capabilities in managing multiple displays simultaneously. These GPUs excel in critical tasks such as emulating the EDID (Extended Display Identification Data) of projectors and merging multiple physical outputs into a single, extended display, features that are typically lacking in consumer GPUs and onboard graphics solutions. ## GPU Feature comparison | Feature | NVIDIA Quadro/RTX | AMD Radeon Pro | Consumer GPUs | onBoard GPUs | | ---------------------- | ----------------- | --------------- | ------------- | ------------ | | **No. outputs** | 4 | 4 | 4 | 1-4 | | **EDID minding** | yes | yes | no | no | | **Display spanning** | yes (Mosaic) | yes (Eyefinity) | no | no | | **Cross-GPU spanning** | yes (Quadrosync) | no | no | no | | **Warp\&Blend** | yes (NVAPI) | no | no | no | | **Availability** | long term | long term | short term | short term | | **Price** | Highest | High | Moderate | Lowest | --- # 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. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://docs.vioso.com/preparation/gpu.md?ask= ``` The question should be specific, self-contained, and written in natural language.
