FAQ

Question: My video output (HDMI, DisplayPort, DVI…) doesn’t work when connected to my device.

Answer:

– Please check if you meet the HW requirements of the docking station

– Use the original accessories supplied with the dock

– Update your device drivers to the latest possible

If your video output still does not work, please contact technical support.

Question: When I close the lid of my laptop, the laptop shuts down. Is there any way 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 options 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 or higher 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 you have the DP 1.2 setting selected in your monitor’s settings. Check your monitor’s manual in case you don’t know where to look for this setting.

Question: Can a monitor connected via a Graphics Adapter use nVidia/AMD/Intel graphics technology? For example, G-sync or FreeSync.

A: The Graphics Adapter can support these technologies, this can be verified by referring to the specifications of the adapter where we list this fact.

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

A: This is possible. The docking station has this option, the condition is that you use the DisplayPort on the docking station.

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: 1. Please try a different higher quality HDMI/DisplayPort cable, this can often solve your problem. Also, please reboot your laptop/computer as well as the docking station.

2. Please update your graphics card drivers directly from the graphics card manufacturer’s website or from the laptop manufacturer’s website.

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

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,the monitor may fall asleep so that it no longer responds to the signal from the dock 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: What are the primary graphics card requirements for use with the graphics chipsets in i-tec graphics adapters and docking stations?

A: The graphics chipsets in i-tec products are secondary (additional) graphics cards in the PC.

They need to have a primary graphics card installed to work.

Note for Windows 10 and later: Intel, NVidia, ATI/AMD, VIA. It cannot work with SiS or Matrox graphics cards.

Question: Can I have 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 are alternating (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 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 (USB-C) port on 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.

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/graphics adapter 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.

Question: Do I need to install the drivers before using the dock?

A: For graphics adapters based on Displaylink technology, we recommend installing drivers beforehand.

However, we always recommend installing the latest version of drivers from the website here: Driver

Question: Can I connect another USB-C DP Alt to the USB-C port of the docking station? Can I connect a USB-C USB-C port to a USB-C-C USB-C port with a USB-C USB-C port?

A: No, the docking station and its USB-C or Thunderbolt port must be adapted for this.

We always state this in the specifications.

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.

A: 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: The dock/graphics adapter is supposed to handle up to 8K/60Hz, but I can only set 4K/30Hz on the monitor. What is the problem?

A: In order to set 5K/60Hz resolution, the main graphics card (in most laptops this is Intel) must support Displayport 1.4 with DSC. Please make sure your laptop supports this.

Question: Can I use this dock/graphics adapter on Linux?

A: Yes, this dock can be used on Linux. DisplayPorts and HDMI are built on USB-C DisplayPort Alt Mode – your distribution/device must support this technology for this output to work on Linux.

The necessary drivers should already be integrated in all current distributions.
