Resolution

Description

Modern USB-C office docking station with support for up to 2 external monitors with 4K resolution. The station is compatible with any laptop equipped with a USB-C, USB4 or Thunderbolt 3/4/5 port. 6x USB ports, reliable and quick connection to your business network thanks to an integrated LAN port and support for installation behind a monitor make the docking station an ideal partner for professionals. And of course, the station is capable of charging your laptop or tablet with up to 100W.

The docking station is available in two versions:
1. without enclosed USB-C charging adapter (product code C31DUALHDMIDOCKPD – this version).
2. with enclosed 100W adapter (product code C31DUALHDMIDPD100/UK)

Note: macOS does not support Multi Stream Transport (MST) technology. Connecting two monitors to the station on macOS will result in both monitors showing the same image.

• Connect up to two 4K/60 Hz external monitors
• Power delivery: up to 100 W
• Two available HDMI ports
• 6x USB ports (1x USB-C 10Gbps, 1x USB-C 5Gbps, 2x USB-A 5Gbps and 2x USB-A 2.0 for easy connection of your USB devices and peripherals.
• Gigabit Ethernet RJ-45 provides reliable, robust and high-speed Internet connection supporting 10/100/1000 Mbps speeds
• Combined jack for audio and microphone on the front panel
• Kensington lock protects against theft, particularly in shared offices or public spaces
• On/off switch for maximum energy savings
• The station features VESA support, allowing smart vertical installation behind a VESA compatible monitor
• Supports Windows 10/11, macOS, Android, iPadOS, ChromeOS and Linux

The docking station can be used without the power adapter. In that case, the HDMI ports, LAN (RJ-45) port, audio/mic and both USB 2.0 ports will always be operational. However, the USB-A ports and the USB-C data ports may not function if a device with higher power requirements is connected (e.g. SSDs, particularly NVMe units). In that case, the docking station may switch off. To use all ports and achieve maximum data transmission speed, it is recommended to use the docking station with the power adapter plugged in.

NOTE: USB-C charger is not included. If you require a docking station with an included USB-C charger, consider the version with product number C31DUALHDMIDPD100.

FAQ

Question: I have two external monitors with built-in speakers. When they are connected to the docking station, the same sound is played from both monitors. Is it possible to set which monitor will play the sound?

Answer: Unfortunately, it is not possible to select which monitor will play the sound using software. 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 there any way to prevent this?

Answer:

Windows has a special setting that controls what happens to the laptop when the lid is closed. This setting needs to be changed. Right-click on the Start button and select Power Options. From the options on the right, select Additional power settings. A new window will open. From the menu on the left, select Lid close settings and select Do nothing.

On macOS, four conditions must be met to prevent the MacBook from shutting down. The MacBook must be connected to a power source, and an external keyboard, mouse, and monitor must be connected. Then you can close the MacBook lid and work with only the external monitor.

Question: I cannot set the resolution to 4K 60Hz on my monitor.

Answer: First, please make sure that both the docking station/graphics adapter and the monitor support this resolution. Also, make sure that:

If you are connecting 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 option in the settings that needs to be turned on.

If connecting via DisplayPort, your cable supports 4K60 Hz. This is only supported by DP cables version 1.2 and newer. Also, make sure that DP 1.2 is selected in your monitor settings. Refer to your monitor manual if you do not know where to find this setting.

Question: Can a monitor connected via a docking station use graphics technologies from nVidia/AMD/Intel? E.g. G-sync or FreeSync.

Answer: For docking stations with this option, we always include it in the specifications.

It mostly depends on whether the guest device, such as a laptop, can offer this option via Thunderbolt, USB-C or USB4 port.

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

Answer: This is not possible. The docking station can handle a maximum of 60Hz.

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

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

Question: The image on the connected monitor is flickering.

Answer: Please try a higher quality HDMI/DisplayPort cable, this may solve your problem.

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

Answer: Converting the signal from HDMI to DisplayPort is possible, but only when using 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: What is the function of the power button if it cannot be used to turn the laptop on/off?

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

Question: I have speakers/headphones connected to the audio connector on the docking station, but no sound is coming out.

Answer: Right-click on the Start button and select Settings. Select System and then select Sound from the menu on the left and change the Output device.

Question: I use a docking station in my office/company, and when I plug the Ethernet cable into the docking station, I cannot connect to the Internet/local network. But when I plug this cable into the LAN connector on my laptop, everything works fine.

Answer: In some cases, companies restrict Internet/local network access to network devices with a known MAC address (each LAN connector has its own MAC address).

This can be circumvented by either 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. i-tec Docker Pro is free and can be downloaded from our website.

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

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

Answer: According to the Thunderbolt 3/USB-C specifications, laptop power is optional. Not all laptops allow this option, especially laptops with a power supply over 100W. Some manufacturers also restrict/block charging from docking stations/adapters not manufactured by them. If you are unsure whether your USB-C port meets the above requirements, please contact either the device manufacturer or our technical support at support@itecproduct.com.

Question: When I disconnect the USB-C Power Delivery adapter from the docking station, the monitor restarts and the USB device disconnects and reconnects.

Answer: This is standard behaviour, as described in the USB-IF Power Delivery specifications. When the adapter is disconnected, the docking station must change the direction of its charging and draw power from the laptop. When the power direction changes, all connected devices will reconnect.

Question: My laptop did not come with a USB-C adapter. Can I use a different USB-C adapter with your dock?

Answer: Yes, this is possible. For example, you can choose any USB-C adapter from our range:

Question: I have a laptop with a USB-C/Thunderbolt3 port, but the laptop is not charging.

Answer: According to USB-C/Thunderbolt3 specifications, laptop power is optional.

Not all laptops support this option, especially laptops that come with a power supply that allows you to charge your laptop at more than 100 W.

Question When I wake my laptop from sleep mode, my external monitor does not wake up.

Answer Try changing the monitor input setting from AUTO to a fixed monitor input.

If the automatic search for an active port does not find any input after a long time,

the monitor may go to sleep and no longer respond to signals from the docking station port.

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

Answer: Yes, if your monitor (projector) has built-in speakers, audio signal transmission via HDMI or DP cable is possible. However, you must change the default audio playback device in your OS settings.

Question: I connected a standard analogue microphone to the docking station’s combined audio port, but the microphone does not work. Why?

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

Question: What are the requirements for 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 the PC.

They require a primary graphics card to function.

Note for Windows 10 and later: In these operating systems, the graphics driver only works with primary graphics cards: Intel, NVidia, ATI/AMD, VIA. It does not work with SiS or Matrox graphics cards.

Question: Can I keep my product in operation continuously (24 hours a day, 7 days a week)?

Answer: Theoretically, yes, but continuous operation is not recommended for the durability and reliability of the product. As with any other device that contains active components on a chip equipped with software or firmware tools, the docking station should be restarted from time to time, especially in locations where connected devices are switched (typically hot-desking and hot-plugging), to prevent potential problems and ensure trouble-free operation. The ideal or recommended usage scenario would be to restart 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, WiFi or Bluetooth stops working, or USB 3.0 devices connected to the docking station disconnect. What is the problem?

Answer: This problem is caused by interference in the 2.4GHz band. A possible solution is to connect the docking station to the Thunderbolt 3 (USB-C) port on the left side of your Mac closest to you or use the ports on the right side. These ports are located furthest from the WiFi antenna. Another solution is to use the 5GHz band and place the docking station as far away from your Mac’s monitor as possible.

Question: I have your device and the image transfer is not working.

Answer: Your device must meet the system requirements, in particular support for DP Alt. mode on the USB-C port. If you are unsure about DP Alt. Mode on your device, please contact either the device manufacturer or our technical support: support@itecproduct.com.

Question: Why does only mirroring work on my MacBook, or only one video output?

Answer: Unfortunately, MacOS does not support MST and is only capable of mirroring to both outputs, or only one may work.

Question: The image via the docking station flickers.

Answer: If you encounter this phenomenon, it is possible that you have set the refresh rate of your monitor incorrectly. If you have set it to 59 Hz, please set it to 60 Hz.

Question: Can HP notebooks equipped with Thunderbolt 3 technology be charged with this docking station?

Answer: Hewlett-Packard has implemented proprietary technology in some of its notebook models that allows charging only when using original HP stations. Please check the compatibility of your notebook with your dealer or contact HP technical support.

Question: Can I connect another USB-C DP Alt. Mode graphics adapter to the USB-C port of the docking station?

Answer: No, this is not supported with this product.

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

Answer: Ethernet connection support must be provided directly by the tablet manufacturer. You can easily check for support in the settings – ‘Network connections’ – ‘Other networks’ – and there should be an ‘Ethernet’ item.

Question: Everything works, but the speed is only 10 Mbps. What is the problem?

Answer: Check all the cabling between the PC/NB and the active device and press the RJ-45 connectors firmly. Replacing the Ethernet cable between the adapter and the active network device (hub, switch, router) with a certified one may also help. Another solution may be to set a specific value (instead of Auto Negotiation) in the network adapter properties, under Speed & Duplex.

Question: Can I use this device on Linux?

Answer: Yes, the docking station supports Linux. Please make sure your distribution is up to date. The docking station uses drivers that are part of the OS – the drivers should already be integrated in all current distributions. Unfortunately, due to the large number of distributions, it is impossible to test all of them.

Question: The docking station should support up to 5K/60Hz, but I can only set 4K/30Hz on my monitor. What is the problem?

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