Plugable Thunderbolt™ 3 HDMI 2.0 デュアル グラフィック変換アダプター Windows、Mac 用

No. Most DisplayPort to HDMI cables and adapters are one-way adapters from a DisplayPort Source (computer or docking station) to a HDMI Sink (television, computer monitor, or projector).  These cables do not work in reverse.

DisplayPort uses packet-based data transmission, breaking the video stream into individual packets of data allows for longer cable runs, use in both copper and fiber-optic cables, and allows for higher bandwidth than other video formats.  It is relatively easy to convert from DisplayPort to HDMI (computers with HDMI output ports already do this internally) and dual-mode DisplayPort outputs have built-in adapters to  output a HDMI signal for use with passive DisplayPort to HDMI adapters.

HDMI uses a video signal, similar to DVI, this requires more power to operate at the same cable lengths as DisplayPort and requires significantly more processing power to create DisplayPort packet-based data.

Externally powered HDMI to DisplayPort adapters do exist, these generally have a USB or small barrel plug for power, and can convert from a HDMI Source to DisplayPort Sink.  In most cases they have reduced resolution or refresh rates compared to modern signal sources and can introduce delay in the data connection between the display and computer potentially causing reduced connectivity or display performance problems.

We do not currently recommend using HDMI to DisplayPort adapter with our docking stations.  In our testing they have been unreliable compared to a native DisplayPort connection.  Many of our  newer docking stations include both HDMI and DisplayPort outputs to reduce the need for additional adapters or adapter cables.

Most Windows notebook computers power management settings will default to putting the computer to sleep with the lid closed, regardless of any external displays, keyboard, or mouse connected to the computer. If this is happening but you would prefer the system to remain active with the lid closed utilizing the external display or displays, these settings can be changed by performing the following:

For Windows 10:

1. Start by right-clicking on the Start button and select Power Options from the menu.
2. From the right side of the Power Options settings page, select the blue link for Additional power settings

   

3. From the choices present on the left-hand side of the Power Options window, please click on Choose what closing the lid does
4. Make sure the setting for When I close the lid under the Plugged In column is set to Do Nothing

   

5. Click the Save Changes button and restart the system (making sure that the laptop’s power adapter is also connected) and test the behavior again.

For Windows 11:

1. Start by right-clicking on the Start button and select Power Options from the menu.

   

2. In the upper left corner of the settings window, in the search box, type "lid" then select Change what closing the lid does from the search results

   

3. Make sure the setting for When I close the lid under the Plugged In column is set to Do Nothing

   

4. Click the Save Changes button to apply the new settings.

Closing the lid should no longer put the computer into sleep mode when an external display and power source is connected, instead one of the external displays should now become the Primary display with the desktop icons instead of the laptop's built-in display.

The lid may still need to be opened to perform the following tasks:

• To power on the computer from a fully powered off state
• To log into the computer if logged out or if the computer is restarted with the lid closed
• To wake the computer from a deep sleep state ( hibernation, or Windows hybrid sleep states )

Synopsis – If your Thunderbolt 3 driver or utility version types are mismatched within a Windows host system, you may receive an error message stating, “Application Cannot run – This Thunderbolt application is not in use anymore and can be safely uninstalled” when attempting to run the Intel Thunderbolt Software management utility or the Intel Thunderbolt Control Center utility. This prevents proper management of Thunderbolt devices on the host system. (This problem does not occur on Apple Mac systems.)

Before proceeding with this or any other procedure that makes changes to your system, please ensure you have a full system backup of any and all important data and create a fresh System Restore Point as a precaution. Plugable will not be able to help restore any data or return a system to a working state should things not work as expected. If you do not wish to take this risk, please do not follow this procedure

You will have to be logged on to the system as a User with ‘Administrator’ permissions in order to perform these steps

1. Disconnect any Thunderbolt 3 devices from the host system (this is done to prevent Windows Update from automatically loading any Thunderbolt drivers).
2. Right-click on the Windows Start button and select ‘Device Manager’.
3. Click on ‘View’ from the application menu bar, and click the option ‘Show hidden devices’ (this is necessary because the Thunderbolt controller will not be active if no Thunderbolt devices are connected).
4. Expand the ‘System Devices’ category. Scroll down until you find the entry for the ‘Thunderbolt Controller’.
5. Right-click on the ‘Thunderbolt Controller’ entry and select ‘Uninstall device’ from the context menu that appears.
6. From the ‘Uninstall Device’ window that appears, click to place a check mark within the ‘Delete the driver software for this device’ option.
7. Click the ‘Uninstall’ button.
8. Close Device Manager.
9. Click the search button on the taskbar (looks like a ‘O’) and search for the letters ‘cmd’.
10. Right-click on the ‘Command Prompt’ search result and select ‘Run as Administrator’ from the context menu. If prompted, enter your Administrator password.
11. From the Administrative Command Prompt window, enter ‘sc delete nhi’ (without the quotes) and press enter. You should receive a ‘SUCCESS’ indicator. ** Be very careful to type this command correctly ** 

This command deletes the ‘nhi’ Windows service presently installed on the system.

Overview and Drivers

In general, Plugable Thunderbolt 3 Docking Stations and Thunderbolt 3 Dual Display Adapters do not require the installation of any drivers when used with macOS or Windows. When connecting a Thunderbolt 3 device, the host operating system should install all the necessary drivers automatically.

However, there are certain instances with Windows systems where additional driver installation may be necessary when using our Thunderbolt 3 docking stations (these are NOT required on macOS systems):

TBT3-UDV Docking Station:

• Windows 10 – In general, no driver installations are required when using Windows 10. After initial connection if all functions of the dock are working as expected, then no additional action is required. However, when the TBT3-UDV is used with certain eighth generation Intel processor-based Windows 10 systems an updated USB 3.0 driver may need to be installed to ensure the best performance of USB peripherals attached to the TBT3-UDV. We recommend installing the updated Asmedia USB 3.0 drivers here. For additional details, please see our TBT3-UDV product page.
• Windows 7 – When using Windows 7 64-bit (32-bit systems are not supported), you will need to install a separate Intel Network Adapter driver and a driver for the Asmedia USB 3.0 Host Controller.

TBT3-UD1-83 / TBT3-UD1-85 Docking Stations:

• Windows 7 – When using Windows 7 64-bit (32-bit systems are not supported), you will need to install a separate Fresco USB 3.0 Host Controller driver and an Intel Network Adapter driver.

General Thunderbolt 3 Information

Before purchasing or using a new Thunderbolt™ 3 docking station or video adapter for use with your personal computer running Windows, you will want to make sure that your computer can support it and be aware of differences from basic USB devices:

Note: The following does not apply to Apple Thunderbolt 3 systems.

• Many early Thunderbolt 3 PCs require firmware and software updates before all adapters and docks will work.
• Dual display support is optional for Thunderbolt 3 PCs. How many displays are supported over Thunderbolt 3 depends on how the USB-C port has been wired on the system motherboard (up to a max of two), and is not changeable in software or by the Thunderbolt 3 graphics device.
• Support for PC charging (USB Power Delivery) on Thunderbolt 3 systems is optional. Many Thunderbolt 3-enabled PCs do not accept a charge over USB-C, and some PCs only will charge with their own branded power adapters.
• Unlike USB devices, Thunderbolt 3 devices must be manually authenticated (approved) for use by the user before the system will recognize them.

Additional detail

• Host computers equipped with Thunderbolt 3 have the ability to install various updates including NVM (Thunderbolt 3 related Non-volatile memory) and PD (Power Delivery) firmware, UEFI BIOS, supplemental Thunderbolt 3 software utilities (for authentication) and various drivers to resolve potential issues and increase compatibility with new Thunderbolt 3 products as they are released.
• System manufacturers have substantial discretion in how they implement various technical elements and features. As a result, compatibility information is complex. As a result many currently available Thunderbolt 3 systems are not fully compatible with our Thunderbolt 3 dual graphics adapters (we do our best to maintain compatibility tables of the individual product pages). Some systems may only be equipped with a single DisplayPort (DP) Alternate Mode (Alt Mode) line to the Thunderbolt 3 port which limits the port to a single display output. Due to this limitation some systems won’t be able to take advantage of our dual port Thunderbolt 3 graphics adapters regardless of firmware/software updates. This is a physical hardware limitation.
• Many system manufacturers ship systems with older firmware and may or may not have updated versions available for download at this time. The latest Thunderbolt 3 firmware for a specific system cannot be downloaded from Intel directly, as it first it has to be customized by the original system manufacturer. Intel has a Thunderbolt updates page with some update information, but as of this writing the list if fairly small. Currently our TBT3-HDMI2X-83 and TBT3-DP2X-83 adapters require the host system to have a Thunderbolt 3 firmware update with NVM version 14 or higher in order to work properly. The latest UEFI BIOS update from your system manufacturer must be installed before updating the NVM firmware.

Operating System Compatibility

Thunderbolt 3 technology is supported by any operating system which has driver support for Thunderbolt 3. Currently, Plugable supports Windows 10, 8.1, and 7 (64-bit only) and macOS 10.13 or later. Although support for Thunderbolt 3 devices under Linux is steadily evolving, Plugable does not support Thunderbolt 3 devices within a Linux environment at this time.

General Thunderbolt 3 FAQ

Q: Can a Thunderbolt 3 dock or adapter work in any system with any USB-C (USB Type C) port?
A: It depends.

• Early Thunderbolt 3 docks and adapters will only work with Thunderbolt 3 USB-C computers and ports and connecting to a USB-C port without Thunderbolt 3 capability will not work. Note that computers and docks may have a mix of Thunderbolt 3 and other USB-C ports that look very similar. Look for the Thunderbolt icon on both sides of the connection to ensure compatibility:

• Current Titan Ridge based docking stations like our TBT3-UDC1 and TBT3-UDZ are backwards compatible with USB-C systems in most cases (with limitations).

Q: How can I identify the NVM version on my system?
A: See “Identifying the NVM” section below.

Q: What if a newer compatible NVM is not available from my system manufacturer?
A: Unfortunately the only option is to contact your system manufacturer and ask when a newer version will be available, and to let them know that until it is, certain accessories you are looking to use will not work.

Q: How can I identify if my system has the necessary two DisplayPort lines to provide dual display output through the Thunderbolt 3 port?
A: Unfortunately in many cases this information is very hard to discern based on the manufacturers published specifications. If your system is not among those listed in our compatibility table above, please contact your system manufacturer for confirmation of how many DisplayPort lines are routed to your Thunderbolt 3 port.

Q: I connected my Thunderbolt 3 dual display adapter and my monitor configuration changed by itself.
A: This may occur and is considered normal. You can change the main display back to your desired screen through the “Display settings” control panel.

Q: I connected my Thunderbolt 3 dual display adapter and am only getting a single output.
A:  Depending on what Thunderbolt 3 equipped system you have, it may only support a single output because of the DP Alt Mode line configuration. See above “Known Host NVM Versions & DP Lines” to find out if your system has one or two lines.

Q: I connected my Thunderbolt 3 dual display adapter for the first time and my system crashed (hard lock).
A: Check to see if your system is running the latest Thunderbolt 3 software, NVM, UEFI BIOS, and all other updates from your system manufacturer. If everything is updated, unplug the adapter, reboot the system, and then reconnect.

Q: I connected my Thunderbolt 3 dual display adapter and am not getting any output to either display.
A: If your system has hybrid graphics (combination of built-in Intel GPU and AMD or NVIDIA discreet graphics) make sure the Intel GPU is set to be the primary GPU in the UEFI BIOS.

It's not uncommon for users to notice a certain level of heat generation from electronics and by extension, Plugable products during operation. In this knowledge base article, we'll explore the reasons behind this heat generation and why it is considered a normal experience within reasonable limits.

Electronics, by their nature, generate heat during operation. This is primarily a result of the electrical current flowing through various components, such as integrated circuits, transistors, and other electronic elements. As Plugable products are designed to efficiently process and transfer data (among other functionality), some level of heat generation is inherent.

Factors Influencing Heat Generation:

1. Power Consumption: The power consumption of a device directly influences the amount of heat it generates. Higher power usage, especially during data transfer or charging processes, can lead to increased heat.
2. Enclosure Design: The design of the product's enclosure and its ability to dissipate heat play a crucial role. Adequate ventilation and heat sinks are often incorporated to manage and disperse generated heat effectively. This is evident in our TBT3-UDZ and TBT4-UDZ designs. The metal case in these docks are designed to function as a heatsink with thermal pads placed throughout the enclosure. This allows heat dissipation from inside to the outside, but will also make it feel as if the device is “too hot”. 
3. Ambient Temperature: The external environment may also play a role. Higher ambient temperatures can contribute to increased perceived heat from the product. This means that summer temperatures may increase the heat generation of not just Plugable products, but many other electronic devices.

Normal Heat Levels: While it is normal for electronic devices to generate heat, Plugable products are engineered to operate within safe temperature ranges. We conduct rigorous testing to ensure that the heat generated during normal operation falls within industry-standard safety parameters. While not all products are or need to be UL certified, we try to go by UL guidelines for thermal readings. The UL threshold is 77C/170.6F, and we aim for around 71C/160F.

Tips for Users:

1. Ventilation: Ensure that Plugable products have sufficient ventilation around them. Avoid placing them in enclosed spaces where heat dissipation may be impeded.
2. Usage Patterns: Intensive tasks such as high-speed data transfer or charging multiple devices simultaneously may result in increased heat generation. This is generally normal but may be more noticeable in such scenarios.
3. Accessories: A number of our devices will allow for the connection of USB accessories and as such, these will require power. If too many “power-hungry” devices are connected, this will cause the device to run much hotter than expected. Be sure to keep in mind the power limits of your dock/device.

In conclusion, experiencing heat from Plugable products is a normal aspect of their operation. Users can rest assured that we prioritize the safety and efficiency of our devices. By understanding the factors influencing heat generation and following simple usage guidelines, users can make the most of their Plugable products while ensuring a reliable and efficient user experience.
