In answer to the bounty question of Joachim Sauer for there's any change about carrying USB signals over physical DP cables/connectors: There hasn't been any change and don't expect one any time soon (or ever). Here is why.
The DisplayPort cable signals specify one lane for auxiliary traffic, as follows:
This auxiliary lane is described by Wikipedia:
The DisplayPort AUX channel is a half-duplex bidirectional data channel used for miscellaneous additional data beyond video and audio (such as I2C or CEC commands) at the device manufacturer's discretion. AUX signals are transmitted across a dedicated set of twisted-pair wires. DisplayPort 1.0 specified Manchester encoding with a 2 Mbaud signal rate (1 Mbit/s data rate). DisplayPort 1.2 introduced a second transmission mode called FAUX (Fast AUX), which operates at 720 Mbaud with 8b/10b encoding (576 Mbit/s data rate). This can be used to implement additional transport protocols such as USB 2.0 (480 Mbit/s) without the need for an additional cable, but has seen little practical use as of 2018.
The DisplayPort 1.2 aux lane only has enough bandwidth to accommodate one USB 2.0, so any USB 3.0 hub would need to connect through a dedicated cable. In practice the Aux lane is rarely used for anything beyond basic management commands for the display and such. Special functions like Ethernet or USB would need support from the graphics card and drivers in order to route data through the GPU's outputs, so are not practical.
There have also been developments since the DisplayPort specification was designed, with the arrival of USB 3.0 that starts at 5 Gbps, and with the introduction of USB Type-C with DisplayPort Alt Mode.
In view of these developments, the DisplayPort Aux channel feature is effectively obsolete. I doubt that it will ever see a move from the industry to implement it. Instead, we have seen the opposite, DisplayPort carried through USB ports.

Question: The video output (HDMI, DisplayPort, DVI …) does not work after connecting to my MacBook even after installing the DisplayLink drivers.
Answer: Apple has added a new security feature to macOS 10.13 and later, which blocks the automatic installation of drivers which use the “kernel” extension. The DisplayLink driver uses these extensions. For proper function, you must allow an exception for DisplayLink Corp, in your MacBook security settings. You can find detailed instructions here:
Question: I have a MacBook with an external 4K monitor connected. In native 4K resolution, the icons are too small, I want to change the display resolution on the monitor, but the image is either blurry or the cursor response is slower.
Answer: Unfortunately, this is a problem with the DisplayLink driver. DisplayLink is working to fix this problem, unfortunately, currently we do not know when this problem will be fixed.
Question: I have 2 external monitors with built-in speakers. When these monitors are connected to a docking station, both of them play the same sound. Can I set up which monitor will play the sound?
Answer: Unfortunately, it is not possible to select a monitor to play the sound. At this time, the only option is to turn it off directly in the monitor settings.
Question: How many maximum external monitors does DisplayLink software support?
- Windows – supports up to 6 monitors – multiple monitors can also be connected, but this is not supported and drivers for more monitors are not tested
- macOS – supports maximum 4 monitors
- Ubuntu – supports up to 2 full HD monitors – multiple monitors can also be connected, but this is not supported and the drivers for more monitors are not tested
- Android – supports maximum 1 external monitor. Additional connected monitors will show the same image as the first connected monitor.
- ChromeOS – The maximum number of monitors is not limited by the DisplayLink driver. But it can be restricted by the ChromeOS itself
Question: After the update of the Windows operating system the docking station does not work.
Answer: Please do the following:
- Disconnect the docking station / video adapter.
- Download and run DisplayLink Installation Cleaner – it can be downloaded in the “Manuals, Drivers” section.

- Reconnect the docking station / video adapter.
Question: The graphic / video editing program (such as Adobe Photoshop) does not work properly on an external monitor connected to the DisplayLink device. But on the laptop’s internal display it works properly. What is the reason and can I fix it somehow?
Answer: It is possible that such programs mistakenly assign the tasks for internal graphics of the computer to the graphics adapter of the docking station and this causes the problems. In this case, you need to disable the graphic acceleration directly in the affected program settings. In different programs, this function may be named differently. Then we recommend restarting your PC / laptop.
Question: When I close the laptop lid, the laptop turns off. Is it possible to prevent it?
- Windows has a special setting which controls what the laptop should do in case of closing the lid. This setting needs to be changed. Right-click the Start button and select Power options. From the options on the right, select Other power settings. A new window opens, and here from the left menu, select Choose what closing the lid does / When I Close the Lid and select Do nothing.
- In macOS there are 4 conditions to be met to avoid turning off the MacBook. The MacBook needs to be connected to the power supply, an external keyboard, mouse, and monitor must be connected. Then you can close the MacBook lid and work with an external monitor only.
Question: I cannot set a 4K 60Hz resolution on the monitor.
Answer: First, please make sure that both the docking station / video adapter and the monitor can handle this resolution. Also, make sure that:
- In case of connecting via HDMI your HDMI cable supports 4K 60Hz. This is supported only by the HDMI cables version 2.0 and later. Some monitors / televisions may also have an option in the settings which needs to be turned on.
- In case of connecting via DisplayPort your cable supports 4K 60Hz. This is supported only by the DP cables version 1.2 and later. Also, be sure that in the settings of your monitor is selected the setting DP 1.2. In case you don’t know where to find it please refer to the manual for your monitor.
Question: Can the monitor connected via the docking station use the graphics technology from nVidia/AMD/Intel? E.g. G-sync, or FreeSync.
Answer: The docking station cannot use the graphics technologies from nVidia/AMD/Intel.
Question: Is it possible to set the frame rate to 120 Hz (144 Hz etc.) with the docking station / video adapter?
Answer: This is not possible. The docking station can handle maximum 60 Hz.
Question: Is it possible to connect a touchscreen monitor?
Answer: This is possible, but in this case i-tec Technologies cannot provide technical support because it is the technology of the monitor manufacturer.
Question: The image on the connected monitor flickers.
Answer: Please try a better HDMI/DisplayPort cable, this can solve your problem.
Question: Can I use a reduction to convert the signal from DVI/HDMI to DisplayPort?
Answer: Signal conversion from HDMI to DisplayPort is possible, but only in case of using the active (powered) adapter. In any case, a passive (non-powered) cable/adapter cannot be used. The passive cables/adapters can only convert the DisplayPort signal to HDMI.
Question: The USB/Thunderbolt 3 cable is too short for my needs. Can I use a longer third-party cable?
Answer: Yes, it is possible. Please see the table below. Here you can see maximum cable lengths according to USB/Thunderbolt 3 specifications. Longer cables may not work properly.
Also, for USB-C and Thunderbolt 3 cables, you need to make sure they support DisplayPort Alt Mode (UBS-C only) and Power Delivery (USB-C and Thunderbolt 3) profiles. In case the docking station need it for its operation.
In case you are not sure, you can contact our technical support: [email protected]
|Cable type||Maximum cable length according the specifications|
|USB 3.0||2 m|
|Thunderbolt 3 – passive cable – maximum rate 40 Gbps||0.75 m|
|Thunderbolt 3 – passive cable – maximum rate 20 Gbps||2 m|
|Thunderbolt 3 – active cable – maximum rate 40 Gbps, not compatible with USB-C||2 m|
Question The external monitor will not wake up after waking up my laptop.
Answer Try changing the monitor’s input setting from AUTO to a fixed monitor input.
If, after a long time, the automatic search for the active port does not find any input,
then the monitor may sleep so that it fails to respond to the signal from the docking station port.
Question: Does this docking station/video adapter support an audio signal transfer over HDMI or DP?
Answer: Yes, if your monitor (projector) has integrated speakers, it is possible to transfer the audio signals via HDMI or DP cable. In your OS settings, however, you must change your default audio playback device.
Question: What are the requirements for the primary graphics cards for use with graphics chipsets in i-tec graphics adapters and docking stations?
Answer: The graphics chipsets in i-tec products are secondary (additional) graphics cards in a PC.
They need a primary graphic card installed for their functionality.
Note for Windows 10 and later: In these operating systems, the graphics driver only works depending on the primary graphics cards: Intel, NVidia, ATI/AMD, VIA. It can’t work with SiS or Matrox graphic cards.
Question: The image on the screen connected via the docking station flashes.
Answer: If you experience this issue, you may only have an improper setting of the monitor refresh rate. If you have setting of 59 Hz, please set to 60 Hz.
Question: Where can I download the driver DisplayLink for ChromeOS?
Response: The ChromeOS drivers do not need to be downloaded or installed. As of version R51, they are a part of ChromeOS. Simply connect the docking station.
Question: I use ChromeOS and the image on the external monitor isn’t consistent/is choppy.
Response: In this case, this is a problem of an inadequate CPU. In most cases, laptops with ChromeOS do not have adequate processors and the DisplayLink software uses only the CPU for calculations.
Question: I have a laptop with ChromeOS with two external 4K monitors, is it possible to set fullHD resolution on both monitors?
Response: Unfortunately, resolution can only be set for one monitor in ChromeOS. The second monitor is set to the maximum possible (native) resolution.
Question: I have a laptop with ChromeOS, is there a limit to how many external monitors I can connect using products built on DisplayLink technology?
Response: The DisplayLink software itself doesn’t have any limitations for ChromeOS but your laptop manufacturer may set up limitations.
Since ChromeBooks tend to have slower processors, connecting several external monitors may burden the processor and the image may be choppy.
Question: I have a different Linux distribution than Ubuntu. Can I still use this device?
Response: Ubuntu is the only officially supported Linux distribution. It’s possible, however, to download drivers on the internet, which were modified for many additional distributions by the Linux community.
If you aren’t sure that your distribution has drivers modified in this manner, or you don’t know where to find them, you may contact our technical support staff: [email protected]
Question: I have an older version of Windows and I’m not able to install the latest DisplayLink drivers. What should I do?
Response: The latest DisplayLink drivers no longer support some older versions of Windows.
Currently, only Windows 7/8.1/10 support the latest DisplayLink drivers.

Partner. But there is also a negative side. For those girls who are used to the sexual sensations that masturbation gives (and maybe even those who know how to bring themselves to orgasm), the first sex. With a partner and deprivation of virginity can be a cruel shock. In any case, it was so with me.
