Sliden’Joy is a gadget that can be magnetized in the back of your computer screen (PC or Mac) and it can effectively double or even triple your visual field, in high definition, simply by plugging it into a USB 3.0 port (USB or two 2.0).
The 180-degree rotation of the displays makes it possible for additional screens to be placed in the direction of your choice, thus keeping the display accessible to people around the table! There are two models available, with one screen – priced at 199 € or with two screens, priced at 299 €. You can choose from these three sizes: 13″, 15″ and 174″.
The start-up that designed Sliden’Joy raised the initial money needed for the project – €300,000.
