Windows has special power management settings that control what happens when the laptop lid is closed. If this happening, these settings need to be changed. Please right-click on the Start button and select ‘Power Options’ from the menu. From the choices present on the left-hand side of the Power Options window, please click on ‘Choose what closing the lid does’. ** Important note – if you are running the Creators Update (or newer) to Windows 10, you will have click on the ‘Additional power settings’ option to access this window ** Make sure the setting for ‘When I close the lid’ under the ‘Plugged In’ column is set to ‘Do Nothing’. Click the ‘Save Changes’ button and restart the system, making sure that the laptop’s power adapter is also connected, and test the behavior again.
If the included three foot USB 3.0 cable is not of sufficient length, a longer cable up to six feet in length can be purchased separately (we don’t recommend cables longer than six feet due to potential performance issues). The type of cable required is a USB 3.0 Type-A to Type-B cable.
Sometimes Photoshop mistakenly attempts to direct graphics tasks intended for your system’s internal graphics adapter to our dock and that can cause problems. As a result, the next step is to disable “Use Graphics Processor” in the preferences by navigating to Edit > Preferences > Performance > Use Graphic Processor and then relaunching Photoshop.
Sometimes mistakenly attempts to direct graphics tasks intended for your system’s internal graphics adapter to our dock and that can cause problems. There is an option to change how the application to directs its graphics tasks, but there are no menus do so within the application itself so the process involves make a small Windows change. The steps are as follows: 1. Please open your Start Menu, search for “Edit Environment Variables for your account” 2. Once there please click “New..” on the top section of the menu. 3. For Variable Name, please type ‘QT_OpenGL’ and for Variable Value please type ‘software’ (Do not enter the quotes) 4. Click OK to close all open windows and then restart the system.
While we don't support our USB graphics devices on Mac, we have reproduced this behavior during internal testing. It appears there has been a regression in the current version of Chrome for OS X (Version 46) which causes graphical distortion when Chrome windows are in use on USB-attached monitors. Until this issue is fixed in a future version of Chrome, the best current workaround is to disable hardware acceleration in the Chrome settings. To do so: Click the Chrome menu header -> Preferences -> Settings -> Show advanced settings -> Scroll down to "System" -> Uncheck "Use hardware acceleration when available". To help make Google aware of the issue so they can properly prioritize fixing it, affected users can report the regression to Google using the built-in bug reporter: Preferences -> About -> Report an issue

The blue LED indicates that the Icy Box US-IB-DK2241AC is being powered by its power adapter. The green LED lights up and stays steady when a device is connected through any of the six USB ports on the dock. If no devices are connected to the USB ports on the Icy Box US-IB-DK2241AC, the green LED only lights up for around five seconds when the dock itself is connected to the upstream system.
That the blue power light blinks indicates the unit is not getting the power it needs to function properly. The first things to check in that case are as follows: That the wall power outlet (or power strip) is working properly. Switching to another outlet or power strip can sometimes help That the ‘prong’ that attaches to the power adapter and provides the blades that insert into the power outlet is securely attached The power adapter is securely connected to the back of the docking station and to the wall power outlet
The Ethernet controller in the docking station requires a full duplex connection. Half duplex connections are not supported. Often, the issue is caused by older Ethernet hubs and/or cabling that do not support full duplex connections.
Powerline-based network adapters are not supported with the Ethernet port within the dock.
The DisplayLink driver does not support color calibration functionality. Most monitors have built-in controls that can be used to adjust the characteristics of the display, though we realize this approach may not be ideal in all cases. For environments that necessitate near-perfect color reproduction and display calibration capabilities via software, a dedicated graphics card is recommended.
The utilities provided by Intel, Nvidia and AMD/ATI are designed to only recognize and work with graphics adapters made by their respective manufacturers and they will not recognize USB-attached displays connected to the dock. It is recommended to use the facilities built-in to Windows to manage the displays connected to the dock (‘Display Settings’ on Windows 10 and ‘Screen Resolution’ on Windows 8.1 and 7).
No, the cable described is a passive cable designed to work in one direction only, from a DisplayPort output to a HDMI input. It will not work in the other direction.
This behavior has been known to occur in rare instances, and is a known bug in the Chrome browser being tracked by the Chrome developers.

    I’m not a big fan of laptops, the screens seem very small, the keyboards are very crowded and the touch pad will never be as practical as a mouse. By necessity I had to buy a portable computer and as I had a previous desktop computer monitor I decided to check if it was possible to use the laptop only as a CPU, although I could connect the monitor through an HDMI cable. connecting and disconnecting the accessories, such as 2 external hard drives, the adapters for the mouse and keyboard. I did not know about the existence of the dockings and I ordered this with some reservation. I could not be more wrong, within minutes of making the order I received a plugable email indicating that I could download the drivers to advance some work before the team arrived.

    When the dock arrived and following the instructions it was not even necessary to use those files, Windows took care of everything and in less than 5 minutes I was already using the monitor as the laptop screen and all the accessories worked as if they had always been connected to the laptop, all this through a single usb cable, when finished just disconnect that cable and the laptop is back as if nothing had happened, all the accesories are plugged to the docking station. Easier is impossible.

    I have not had any performance problems, even with full screen video, highly recommended!

    EXACTLY WHAT I WANTED!!! Was looking for a way to add two additional monitors to my laptop (so, three total) without having to upgrade my graphics card. This works perfectly. Plus, there are PLENTY of ports to add all my peripherals (cordless keyboard and mouse, printer, external backup device, cellphone, and multiple USB thumb drives), and I still have extra ports I don’t know what to do with.

    I plug exactly one cord into a USB port in my laptop, and have INSTANT access to all of my peripherals (no delay). Likewise, when plugging in a thumb drive, it shows up as accessible instantly. (No absurd waiting time for the unit to register the device.) I have used with two separate Lenovo laptops and a Toshiba laptop, and have been able to use it with Windows 7, 8.1, and 10. I also successfully hooked it up to a Mac after downloading a separate driver (worked fine for me me – but, I only used it the one time, so can’t give a full endorsement of using it with a Mac).One of the problems I had encountered with devices that sit vertically and have multiple connections is their tendency to move around on the desk due to the pulling of the connected cables. This device appears to have just enough mass to prevent that from happening.
    Reading Amazon reviews prior to my purchase, I was impressed by the way the company appears to stand behind their products. I saw quite a few comments from Plugable following reviews from those who encountered problems with the product. I was also impressed with the video reviews on Youtube that I believe were done by the company’s owner or president. Amazon makes it easy to read many reviews, and when a company stands behind their products the way Plugable appears to do, it makes me want to help expand their business.
