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 the “kernel” extension. 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: When I close the lid of my laptop, the laptop shuts down. Can I prevent this from happening?

Answer:

– Windows has a special setting that controls 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.

– On macOS , there are 4 conditions that must be met to prevent the MacBook from shutting down. The MacBook needs to be connected to power, the external keyboard, mouse and monitor need to be connected. And then the MacBook lid can be closed and only the external monitor can be used.

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

A: Please first make sure that both the dock/graphics adapter and the monitor can handle this resolution. Please 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 4K60Hz. Only DP cables version 1.2 and later support this. Also make sure that 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 docking station cannot use nVidia/AMD/Intel graphics technologies.

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

A: Yes, this is officially supported with the latest DisplayLink DL7400 chip.

Question: Is it possible to connect a monitor with a touch screen?

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

Question: The image on the connected monitor is flickering.

A: Please try a different higher quality HDMI/DisplayPort cable, this can often solve your problem. Please also 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, you cannot use a passive (non-powered) cable/adapter 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, you can 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 connected in the audio jack of the dock, but they do not play any sound.

A: Right-click the Start button 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 area 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 network connections to network elements with a known MAC address (each LAN connector has its own MAC address).

You can work around this by either manually changing the MAC address of the LAN connector in the docking station, or you can use our i-tec Docker Pro software (Windows only) to clone the MAC address from your laptop to the docking station. 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, powering the laptop 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 whether your USB-C port meets these requirements, please contact either the device manufacturer or our technical support: support@itecproduct.com.

Question: My external monitor does not wake up when I wake my laptop from sleep.

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.

In case of any problems after waking up, the sleep or hibernation mode on some devices needs to be turned off.

Question: Does this dock/graphics adapter support audio signal transmission via HDMI or DP?

A: Yes, if your monitor (projector) includes 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 have connected a standard analog microphone to the dock’s combined audio port, but the microphone does not work. Why?

A: The combo (TRRS) audio port is not compatible with standard analog microphones.

Question: Can I have my product in use 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 should 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 trouble-free. 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 USB 3.0 devices connected to the dock disconnect. Where is the problem?

Answer: 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 video 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 unsure about DP Alt. Please contact either the device manufacturer or our technical support: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.

Question: The image through the docking station flickers.

A: If you experience 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 with this dock?

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 docking station?

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-C port to the USB-C-C USB-C port with a graphics adapter?

Answer: No, the dock and its USB-C or Thunderbolt port must be adapted for this. We always state this in the specifications.

Question: The LAN connection is not working on my Android.

A: Support for Ethernet connectivity must be supported directly by the tablet manufacturer. You can easily check for support in the settings – “Network Connections” – “Other Networks” – and the “Ethernet” entry must be there.

Question: Everything works for me, but it only shows a speed of 10 Mbps, where is the problem?

Answer: Check 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 my external monitor is not smooth/blurry.

Answer: In this case, the problem is 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.

Q: Can I expect a worse system response if most of the video output of the dock is fitted?

A: Yes, you can expect a rapid decrease in system performance and smoothness depending on the number of monitors connected and their resolution/frequency.

This is especially true for laptops with only an integrated graphics card or laptops that do not have dual-channel memory.

Question: Is it possible to affect the overall system response if most of the video outputs of the dock are fitted?

A: Yes, several factors can affect the overall system response.

1.

2. The same resolution on all connected monitors.

3. In the case of connecting an 8K TV or monitor, we recommend a significant reduction in resolution to at least 4K (2024 laptops are barely ready for daily use of 8K resolution)

4. Install the latest displaylink driver: https://www.synaptics.com/products/displaylink-graphics/downloads

5. Update the GPU driver of the host device usually AMD, Intel or Nvidia.

Question: My 144Hz monitor doesn’t have the same smoothness/response as when I plug the monitor directly into the host device.

A: The dock has hybrid technology, offering ports connected directly to the host device’s graphics card or ports connected via displaylink technology.

We recommend connecting higher refresh rate monitors through ports that are connected directly to the host device’s graphics card.

Monitors connected via Displaylink may suffer from these ailments depending on the current CPU/GPU and RAM usage of the host device.

Question: My monitor does not offer 8k60Hz resolution or 4k144Hz etc. when connected to the dock.

A: Make sure you are connecting the monitor to the correct DisplayPort supporting the appropriate resolution.

If you are connecting it to the correct DisplayPort and still cannot achieve the proper resolution then we recommend that you contact our support at support@itecproduct.com
