Displaylink Exhibits 4x4K monitors over USB
August 16, 2016, Intel Developer Forum, San Francisco—Displaylink showed a single USB 3.0 port driving four 4k p60 monitors. This setup greatly expands the possible screen real estate from a single computer and allows lower-end computers to perform tasks formerly restricted to workstations.
The company produces ships and software for display expansion. Their chipsets for the interfaces go into other OEM products, while their software has drivers and compression to feed the external chips. The external subsystem with their chips handles the USB 3.0 type C or A interface and decompresses the data streams to expand to fill two 3840x2160 displays all at p60, along with Gigabit Ethernet, Audio and USB expansion. The expander systems can be daisy-chained to enable up to 4 x4k displays.
The various OEM developers have numerous configurations for I/O, including USB, HDMI, and DisplayPort and their powered hubs can also run a USB display and charge another device. As a result, the external devices offer good flexibility and scalability for those needing more screen space and extended I/O ports. For a person who wants to travel light, your presentation could be on a tablet device which is connected to a powered DisplayLink hub to a USB display. This configuration eliminates the clutter and weight of a laptop and its accessories.
The docking stations and hubs can be useful in situations where the user needs to view lots of detailed content at up to 4k resolution, yet most of the content is fairly local, as in editing video files. These devices open a wide range of computers to levels of performance, productivity, and expansion formerly available only in very high-end workstations and server farms.
