The product fades bezels and creates a better viewing experience. Thin lenses are placed along the seams where screens meet; they contain optical micro-structures that refract light, bending it inward to hide the bezels underneath.
The lenses are made from a transparent thermoplastic that’s much more durable than glass. This material lets 90% of the light from the monitors shine through, making a more fluid multi-monitor experience.
In an effort to make the product ASUS exclusive, they have made custom clips and allow no extension for the small variation between monitor heights. Despite their best efforts, I expect we will see many knock offs of this brilliant concept.
