USB monitor run on linux

USB monitor
Linux users should soon be able to use USB-connected monitors. DisplayLink has released Linux versions of its USB monitor and has partnered with Novell and the Linux Driver Project to develop drivers for desktops and mobile devices. DisplayLink’s chips are embedded in a growing number of USB-connected monitors, such as Mimo Monitors' little Mimo 710 enabling one or more high resolution displays to be connected via a standard USB 2.0 port.

Previously available only on Windows and Mac, the drivers can now be developed for Linux devices now that the source code library has been released under GNU Lesser General Public License v2 (LGPL). The library should enable the development of Linux X Servers, drivers, and other applications that work with the DisplayLink-compatible technology. As a result, USB-to-monitor attachments should be available on Linux devices including netbooks, notebooks, mobile Internet devices (MIDs), mobile phones, embedded displays, embedded devices, and digital signage.

A DisplayLink driver compresses graphics using adaptive compression technology that automatically balances compression methods based on the content, available CPU power, and USB bandwidth. The data is then sent out through the USB port to a monitor or other device with an embedded DisplayLink DL-120 or DL-160 chip, which include a USB port on one side and an analog, DVI, or FPI (LVDS) video port on the other. The chip decompresses the stream and enables instant cloning or extending of a desktop among multiple displays.

To accelerate deployment and development of Linux drivers and other software, DisplayLink has established partnerships with both Novell and the Linux Driver Project (LDP). Company is expecting to launch this USB monitor as soon as possible.
