c31tripledockpd-2
New

USB-C docking station capable of supporting up to three 4K/60 Hz external monitors using any Windows 10 notebook. The integrated DP 1.4 protocol also supports a 5K/60Hz monitor, making this dock an ideal solution for professional graphic designers, data analysts, engineers, film editors or enthusiasts. With up to 85W USB-C Power Delivery via your USB-C or Thunderbolt 3 port, you can charge your notebook while you work.

Connect quickly and easily to your notebook or tablet – no driver installation required – and benefit from a data transfer rate of 10 Gbps via the USB-A 3.1 and USB-C ports, and charge your smartphone via the 10W fast charge port.

Please note, the ability to connect three external monitors relies on the graphics card of your notebook, although the vast majority, i.e. Intel integrated cards, do so. You may need to work with the notebook lid closed to use three external monitors. Connect the dock via a USB-C port that supports video transfer (DisplayPort Alt Mode) and with power supply, or via a Thunderbolt 3 port.

FAQ

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: 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: 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: 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.

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: 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.

Answer: The combined (TRRS) audio port is not compatible with the standard analogue microphones.

 

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: I have your device and the image transfer does not work.
Answer: Your device must meet system requirements, especially DP Alt. Mode support on the USB-C port. If you are not sure about DP Alt. Mode support on your device, please contact your device manufacturer or our technical support: support@itecproduct.com.

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: There is no working LAN connection on my Android.
Answer: The Ethernet connection must be supported directly by the tablet manufacturer. You can easily verify the support in the set-up “Network Connections” – “Other Networks” – and the option “Ethernet” must be located here.

 

Question: May I use this device in Linux?
Response: Yes, the docking station supports Linux. Please make sure that your distribution is up to date. The docking station uses drivers, which are a part of the OS – the drivers should already be integrated in all current distributions. Unfortunately, because of the large volume of distributions it is not possible to test all of them.

If you aren’t certain, please contact our technical support staff: support@itecproduct.com

 

Question: The docking station should manage up to 5K/60Hz but I am only able to set up 4K/30Hz on the monitor. What’s the problem?
Response: In order to set up 5K/60Hz, the main graphic card (this is Intel on most laptops) must support DisplayLink 1.4 with DSC. Please make sure your laptop supports this.

 

Question: I have a laptop, which needs 85 W but the laptop battery depletes slowly during heavy use.
Response: Please disconnect all devices from the front USB connectors. If a device is plugged into any of the front connectors, the docking station is only able to deliver 65 W. In order for the docking station to provide 85 W, the front connectors must be disconnected.
