FAQ

Question: My video output (HDMI, DisplayPort, DVI…) does not work after connecting to my MacBook or after installing DisplayLink drivers.

A: Apple has added a new security feature to macOS 10.13 and later that blocks the automatic installation of drivers that use “kernel” extensions. The DisplayLink driver uses these extensions. To work properly, you must enable the “DisplayLink Corp” exception in your MacBook’s Security Settings. Detailed instructions can be found here:

Question: I have 2 external monitors with built-in speakers. And when they are connected to the docking station it plays the same sound from both of them. Is it possible to set the monitor to play the sound?

A: Unfortunately, it is not possible to select the monitor that will play the sound in software. At the moment, the only option is to turn it off directly in the monitor settings.

Question: After updating the Windows Operating System, the docking station does not work.
A: Please do the following:

1. Download and run DisplayLink Installation Cleaner – download in the “Manuals, Drivers” section
2. Restart your device (computer, laptop, etc.)
3. Connect the docking station/graphics adapter
4. Download and install the latest DisplayLink drivers – available in the “Manuals, Drivers” section or here: Driver

Question: When I close the lid of my laptop, the laptop shuts down. Is there anything I can do to prevent this?

Answer:

• Windows has special settings that control what happens to the laptop when the lid is closed. And this setting needs to be changed. Right-click on the Start button and select Power Options. From the options on the right side, select More power settings. A new window will open and from the menu on the left side, select Lid Close Settings and select Do no action.
• For macOS, there are 4 conditions that must be met to prevent the MacBook from shutting down. The MacBook needs to be connected to power, an external keyboard, mouse and monitor. And then the MacBook lid can be closed and only the external monitor can be used.

Question: I can’t set my monitor to 4K 60Hz resolution.

A: Please first make sure that both the docking station/graphics adapter and the monitor can handle this resolution. Also make sure that:

• If connected via HDMI, your HDMI cable supports 4K 60Hz. Only HDMI cables version 2.0 and later support this. Also, some monitors/TVs may have an item in the settings that needs to be enabled.
• If connected via DisplayPort, your cable supports 4K60 Hz. Only DP cables version 1.2 and later support this. Also, make sure you have DP 1.2 or later selected in your monitor settings. Check the manual for your monitor in case you don’t know where to look for this setting.

Question: Can a monitor connected via a docking station use nVidia/AMD/Intel graphics technologies? For example, G-sync or FreeSync.

A: The dock cannot use nVidia/AMD/Intel graphics technologies.

Question: With the docking station/graphics adapter, is it possible to set the frame rate to 120 Hz (144 Hz, etc.)?

A: This is not possible. DisplayLink based docking stations/graphics adapters can only handle a maximum of 60Hz.

Question: Is it possible to connect a touchscreen monitor?

A: This is possible, but i-tec Technologies cannot provide technical support in this case as it is a monitor manufacturers technology.

Question: The image on the connected monitor is flickering.

A: Please try another higher quality HDMI/DisplayPort cable, this can often solve your problem. Also, please reboot your laptop/computer and also the docking station.

Question: Can I use an adapter to convert the signal from DVI/HDMI to DisplayPort?

A: You can convert the signal from HDMI to DisplayPort, but only if you use an active (powered) adapter.

Therefore, a passive (unpowered) cable/adapter cannot be used under any circumstances. Passive cables/adapters can only convert DisplayPort signals to HDMI.

Question: The USB/Thunderbolt cable is too short for my needs. Can I use a longer cable from another manufacturer?

A: Yes, it is possible to use other longer cables. However, we are not responsible for any problems caused by using third party cables.

Question: What is the function of the Power button if I cannot turn the laptop on/off with it?

A: The power button is used to turn the docking station on/off.

Question: I have speakers/headphones plugged into the audio jack of the dock, but they don’t play any sound.

A: Right-click Start and select Settings. From here, select System and from the menu on the left side, select Sound and change Output Devices here.

Question: I use a docking station in my office/company, and when I plug the Ethernet cable into the docking station, it is not possible to connect to the internet/local networks. But when I plug this cable into the LAN connector on my laptop, everything works properly.

A: In some cases, companies restrict Internet/local area network connectivity to network elements with a known MAC address (each LAN connector has its own MAC address).

You can work around this either by manually changing the MAC address of the LAN connector in the dock, or you can use our i-tec Docker Pro software (Windows only) to clone the MAC address from your laptop to the dock. i-tec Docker Pro is free and can be downloaded from our website.

Question: I have a laptop with a Thunderbolt 3/4 or USB-C port, yet the laptop won’t charge.

A: According to the Thunderbolt 3/4 and USB-C specifications, laptop power is only optional. Not all laptops allow this option, especially laptops with power supplies over 100W. Also, some manufacturers restrict/block charging from docks/adapters not made by that manufacturer. If you are unsure if your USB-C port meets these requirements, please contact either the device manufacturer or our technical support: support@itecproduct.com.

Question: When I wake my laptop from sleep, the external monitor does not wake up.
A: Try changing the monitor input setting from AUTO to a fixed monitor input.
If after a long time the automatic search for an active port does not find any input,
then the monitor may go to sleep so that it no longer responds to the signal from the docking station port.

Some devices require you to turn off sleep or hibernation if you have any problems after waking up.

Question: Does this dock/graphics adapter support audio signal transmission via HDMI or DP?
A: Yes, if your monitor (projector) has integrated speakers, audio signal transmission via HDMI or DP cable is possible. However, you need to change the default audio playback device in your OS settings.

Question: I connected a standard analog microphone to the dock’s combined audio port, but the microphone doesn’t work. Why?
A: The combo (TRRS) audio port is not compatible with standard analog microphones.

Question: Can I keep my product running permanently (24 hours a day, 7 days a week)?
A: Theoretically yes, but continuous operation is not good for product durability and reliability. As with any other device that contains active on-chip components equipped with software or firmware tools, the docking station needs to be rebooted once in a while, especially in areas where connected devices alternate (typically hot-desking and hot-plugging) to avoid potential problems and keep operation smooth. The ideal or recommended usage scenario would be to reboot or shut down the product at least three times a week. Docking stations that are not equipped with an ON/OFF button can be turned off by disconnecting the power supply unit.

Question: On my MacBook 13″ / 15″ 2016 and later, my WiFi or Bluetooth stops working, or my USB 3.0 devices connected to the dock disconnect. Where is the problem?
A: This problem is caused by interference in the 2.4GHz band. A possible solution is to connect the dock to the Thunderbolt 3/4 (USB-C) port of the Mac on the left side closest to you or use the ports on the right side. These ports are located farthest from the WiFi antenna. Another solution is to use the 5GHz band and place the dock as far away from your Mac’s monitor as possible. For more information, see here: https://support.apple.com/en-us/HT201163

Question: I have your device and the image transfer is not working.
A: Your device must meet the system requirements, especially any DP Alt. mode support on the USB-C port. In case you are not sure about DP Alt. Please contact either the device manufacturer or our technical support at: support@itecproduct.com.

Question: Why does only mirroring or only one video output work on my MacBook?
A: Unfortunately, macOS does not support MST technology and is only capable of mirroring both outputs, or only one output can work. (Not valid for Displaylink based docking stations, P/Ns for these start with CA or U3)

Question: The image through the dock is flickering.
A: If you are experiencing this phenomenon, you may just have the monitor refresh rate set incorrectly. For example, if your refresh rate is set to 59 Hz, please set it to 60 Hz and vice versa. Try switching the monitor mode from DP 1.2 to DP 1.4 and vice versa. Turn off any additional monitor technologies: G-Sync, FreeSync, HDR, etc.
Question: Is it possible to charge HP laptops equipped with Thunderbolt 3/4 technology with this docking station?
A: Hewlett-Packard has implemented a proprietary technology in some of its notebook models that allows charging only when using genuine HP docks. Please check your laptop’s compatibility with your dealer or contact HP Technical Support.

Question: Do I need to install drivers before using the dock?
A: No, installation is only required on Windows 7, Android and macOS. However, we always recommend installing the latest version of drivers from the site here: Driver

Question: Can I plug another USB-C DP Alt into the USB-C port of the dock? Can I connect a USB-C USB port to a USB-C USB-C port with a USB-C USB port?
A: No, the docking station and its USB-C or Thunderbolt port must be designed for this. We always state this in the specifications.

Question: LAN connection is not working on my Android.
A: Ethernet support must be supported directly by the tablet manufacturer. You can easily check for support in the settings – “Network Connections” – “Other Networks” – and there must be an “Ethernet” entry.

Question: Everything is working, but it only shows 10 Mbps, what’s the problem?
A: Verify all cabling between the PC/NB and the active element and tighten the RJ-45 connectors. It also helps to replace the Ethernet cable between the adapter and the active network element (hub, switch, router) with a certified one. Setting a specific value (instead of Auto Negotiation) in the properties of the network adapters, the Speed & Duplex item may also be a solution.

Question: Where can I download DisplayLink drivers for ChromeOS?
A: There is no need to download or install drivers for ChromeOS. They have been included with ChromeOS since R51. Just plug in the dock.

Question: I’m using ChromeOS and the image on an external monitor is not smooth/choppy.
A: In this case it is a problem with an underpowered CPU.  In most cases, ChromeOS laptops use less powerful processors and the DisplayLink software uses the CPU exclusively for calculations.

Question: I have a ChromeOS laptop with two external 4K monitors, is there any way to set FullHD resolution on both monitors?
A: Unfortunately, at the moment, you can only set the resolution for one monitor on ChromeOS. The second monitor is set to the maximum possible (native) resolution.

Question: Can I use this dock on Linux?
A: Yes this dock can be used on Linux. Only Ubuntu is officially supported from Linux distributions. But you can download drivers on the internet that have been modified by the Linux community for many other distributions.
