A foldable triple monitor is a portable display setup that attaches to a laptop to provide two additional screens, creating a three-screen workstation. It typically features two 13.3 to 15.6-inch Full HD (1920x1080) IPS panels that fold out from a central unit, and it connects to a laptop via a single USB-C cable. When not in use, the side screens fold inward to protect them, and the entire unit folds up for easy transport, often resembling a briefcase.
