An RJ-45 Gigabit Ethernet network port (also supports 10/100 Ethernet)
External speaker output jack and a microphone line in
Two USB 3.0 ports for accessories (such as an external hard drive or another graphics port)
Four USB 2.0 ports (great for a keyboard and mouse with two ports to spare)\n\nSpeed and Power\n\nUD-3000 frontal viewPerformance is best when hooking up the UD-3900 docking station to a USB 3.0 port on a PC, allowing SuperSpeed data-transfer rates of up to five gigabits per second between the computer and the dock’s USB 3.0 components and ports. Play full-motion video in 1080p on the monitors attached to the dock’s video ports. Access your Gigabit Ethernet network through the dock’s network adapter without bottlenecks. Open files in lightning-fast time on external drives connected to the docking station’s USB 3.0 ports. The UD-3900 also can be connected to a computer’s USB 2.0 port, though communications between the computer and the docking station will be no faster than the USB 2.0 maximum of 480 megabits per second.\n\nThe UD-3900’s four-amp power supply provides current for attaching bus-powered devices to the spare USB 2.0 and 3.0 ports, like flash drives or additional USB graphics adapters. However, the unit is not a charging hub. It has no functionality for recharging iPads, iPods, other tablets, or smartphones via its USB ports.\n\nThe dock will wake along with your PC from suspend and hibernation modes.\n\nIntegrated Chipsets\n\nThe heart of the docking station is its DisplayLink DL-3900 chipset, which manages dual graphics and audio output and Gigabit Ethernet functions. The integration of these functions on a single chipset means fewer internal components need to be bolted together, leading to increased compatibility and reliability overall. Drivers are installed automatically from Windows Update if an Internet connection is present when the docking station is first connected (a drivers CD also comes in the box).\n\nYou can extend or mirror your primary Windows desktop to a monitor connected to the UD-3900. With DisplayLink technology, graphics processing still is handled by connected computer’s central processor and graphics processor. The DisplayLink drivers on that PC compress and transmit pixels to the DL-3900 chipset, which decodes the data and displays it.\n\nThe UD-3900 can be used in conjunction with any of Plugable’s other USB graphics adapters for adding extra monitors. Please note that USB graphics adapters not powered by DisplayLink technology cannot be used on your PC simultaneously with the UD-3900. Drivers for non-DisplayLink USB graphics adapters must be uninstalled from the PC.\n\nThe internal USB 3.0 components and two extra ports are managed by a VIA VL811 chipset, while the USB 2.0 controller chipset for the four USB 3.0 ports comes from Terminus Technology. USB 3.0 devices must be connected to USB 3.0 ports for proper functionality, but USB 2.0/1.1 devices can be connected to any of the six USB ports.\n\nWhat’s in the Box\n\nThe Plugable UD-3900 comes with a four-amp, five-volt power supply; a USB 3.0 Type-A male to Type-B male cable; a passive DVI-to-VGA port adapter; a quick-install guide; and a drivers CD.\n\nResolutions Supported\n\nThe hardware is capable of supporting nearly arbitrary resolutions, up to its limit of 2560x1440 (HDMI) / 1920x1200 (DVI). VESA standard and widescreen resolutions are supported by most software, including: 2560x1440 (HDMI Only), 1920×1080, 1600×1200, 1680×1050, 1440×900. 1400×1050, 1280×1024, 1280×768, 1280×720, 1152×864, 1024×768, 800×600, 640×480. For all supported resolutions (other than 2560x1440 which has a 50Hz refresh rate), the display is refreshed at 60Hz, and the hardware is capable of 16, and 32bpp color depths. Some operating systems require specific depths, like 32bpp for Windows Aero support.\n\nHardware Requirements\n\nDual Core Intel or AMD CPU, 2GHz or better. Windows GPU should be Intel, AMD, or Nvidia.\n\nOperating System and Driver Details\n\nWINDOWS VERSION COMPATIBILITY:\n\nDrivers can be installed automatically via Windows Update with support for Windows 10, 8, 7, and XP. Not compatible with ARM-based Windows RT/Surface RT. Note that Microsoft limits multiple display support in Windows 7 “Starter” Edition to mirroring screens. Even though drivers are provided automatically, we recommend visiting the Plugable driver webpage for the most recent drivers and other information.\n\nDisplayLink's Windows drivers make use of the main GPU for rendering, and require an Intel, nVidia, ATI/AMD primary graphics driver supporting WDDM to be installed. Most systems since Windows 7 satisfy this requirement.\n\nDifferent USB graphics driver types (DisplayLink, MCT/Tritton, SMSC, Fresco) are not compatible on the same system. In particular, some versions of MCT drivers will bluescreen when other USB graphics drivers are also present. Uninstall other USB graphics driver types before switching types, and stay with a single type (e.g. DisplayLink based) on a single system.\n\nMAC COMPATIBILITY:\n\nMac is not supported due to significant limitations in the operating system.\n\nLINUX COMPATIBILITY:\n\nLinux is not supported for this device.\n\nTOUCHSCREEN COMPATIBILITY:\n\nSome touchscreens are compatible, it is dependent upon whether the touchscreen monitor software supports multiple monitor setups. Please contact your monitor manufacturer to determine if multiple monitor setups are supported.\n\nHDMI TV Compatibility\n\nThe docking station supports HDMI through the 1.3 standard. To use a TV as a monitor via the dock, the TV must support EDID, the extended display identification standard for communicating monitor capabilities to a PC. Many TVs that have a VGA port in addition to an HDMI port assume that computers will use VGA for connectivity rather than HDMI. In these cases, a VGA connection from the PC’s internal video card to the TV might provide the best results.\n\nHDCP protected content not supported.\n\nPerformance Tuning\n\nIf you’re experiencing slowness or latency on your UD-3900 connected display:\n
Make sure your adapter is connected to a USB 3.0 port (if available) on your computer.
If USB 3.0 is not available, play 3D games and videos on a display that isn’t connected via USB.
When all else fails, reduce your USB-connected monitor’s screen resolution via the Windows display control panel.\n\nBy reducing the amount of data that needs to be compressed and sent over USB, you’ll increase responsiveness.\n\nGaming\n\nUSB graphics devices, like the UD-3900, are "virtual" devices where much of the heavy lifting is done by the CPU, by hooking into the graphics stack. The DirectX APIs used by games assume direct hardware access (a PCIe graphics card). DisplayLink's drivers attempt to emulate as much of the functionality as possible, which is why some 3D functionality (like that needed for desktop and apps) works.\n\nWe don't recommend running games with USB graphics, because this emulation cannot be perfect. And even without specific compatibility problems, performance will always be a challenge - the extra CPU work required for USB graphics will be a source of reduced frame rates and problems. Normal desktop and application use are fine because they don't push the system as hard as 3D games do.\n\nCommon problems experienced when trying to run a game on a USB graphics adapter include:\n
Games not launching
Games crashing
Screen flickering
Screen going black
