FAQ

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:

https://i-tec.cz/en/setup/

 

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?

Answer:

  • 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:

  1. Disconnect the docking station / video adapter.
  2. Download and run DisplayLink Installation Cleaner – it can be downloaded in the “Manuals, Drivers” section.
  3. Download and install the latest DisplayLink drivers – these can be downloaded in the “Manuals, Drivers” section.
  4. 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?

Answer:

  • 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: support@itecproduct.com

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

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

 

Question: I have attached speakers/headphones in the docking station’s audio connector, but they do not play any sound.

Answer: Right click the Start button and select an option Settings. Here select System and from the menu on the left select Sound and change here the Output device.

 

Question: I use a docking station in the office/business, and if I plug the Ethernet cable into the docking station, I can’t connect to the internet/local area network. But when I plug this cable into the LAN connector in the laptop, everything works properly.

Answer: In some cases, the businesses limit the LAN/local network connection only to the network elements with a known MAC address (each LAN connector has its own MAC address).

This can be bypassed either by manually changing the MAC address of the LAN connector in the docking station, or by using our i-tec Docker Pro software (for Windows) which clones the MAC address from your laptop to the docking station. The i-tec Docker Pro is free and you can download it from our website. https://i-tec.cz/en/produkt/dockerprosw-2

 

Question: Can the docking station charge the laptop via USB 3.0 connector?

Answer: From a technological point of view, the USB 3.0 specification does not support laptop charging via the USB 3.0 connector.

 

Question: I have a laptop with a Thunderbolt 3 or USB-C port, but the laptop does not charge anyway.

Answer: According to the Thunderbolt 3/USB-C specifications, the laptop powering is only optional. Not all laptops allow this option, especially the laptops with a power supply of over 100 W. Also, some manufacturers restrict/block charging from docking stations/adapters which are not produced by given manufacturer. If you are not sure whether your USB-C port meets these requirements, please contact your device manufacturer or our technical support: support@itecproduct.com.

 

Question: I have a laptop with a USB-C/Thunderbolt3 port, but the laptop does not charge anyway.
Answer: According to the USB-C/Thunderbolt 3 specifications, the laptop powering is only optional.
Not all laptops allow this option, especially the laptops supplied with a power supply which allows to charge your notebook with more than 100 W.

 

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

 

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: Can I use this docking station/video adapter also via the Thunderbolt3 port?
Answer: Yes, the USB-C docking station/graphics adapter can also be used via the Thunderbolt3 port.
Only the Power Delivery may not work, but it depends on the TB3 features of your laptop.

 

Question: Can I connect another USB-C DP Alt. Mode graphic adapter to the USB-C port of the docking station?
Answer: In the case of USB-C DP Alt. Mode technology, it is not possible to use multiple adapters by connecting them in series.

 

 

Question: Everything works fine, but it only shows the speed of 10 Mbps. Where is the problem?
Answer: Verify all the cabling between the PC/laptop and the active element and push the RJ-45 connectors. Sometimes can also help replacing the Ethernet cable between the adapter and the active network element (hub, switch, router) with a certified one. A solution can also be setting a specific value (instead of Auto Negotiation) in the properties of the network adapters, Speed & Duplex option.
