Graphics cards
General considerations
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.
