Q. アクティブアダプターとはなんですか？ パッシブアダプターとアクティブアダプターは何が違うのですか？
A. DisplayPort 信号は、HDMI、DVI などのデジタル信号ですが、異なった方式で信号を取り扱います。またデジタル信号であるため、アナログ信号である VGA とも全く異なります。アクティブアダプターは、DisplayPort 信号を実際に HDMI、DVI、VGA 信号などに変換するためのチップセットを内蔵しています。
一方、パッシブタイプのアダプターには変換チップは内蔵されておらず、DisplayPort 信号出力のうち必要な信号を選択して透過させるだけの、PC システムのグラフィックコントローラに依存した仕組みになっています。DisplayPort 信号を HDMI 信号に正しく変換するアクティブアダプターにくらべると、通常の場合対応できる解像度やリフレッシュレートが低くなります。また AMD Eyefinity や NVIDIA Surround 機能を使う構成では、接続できるディスプレイの数が制限されます。
なぜこの変換アダプターは HDR 4K テレビで使えないのですか？
A. リフレッシュレートが制限されますが、使えることがあります。HDR または HDR 10 は、コンピュータとディスプレイ間で色と光度用の追加データを必要とする、新しい技術です。これに対応するためには、PC 側のグラフィック出力は DisplayPort 1.4 または、HDMI 2.0b または HDMI 2.1 に対応している必要があります。一方、この Plugable DP-HDMI 変換アダプターは SDR（非 HDR）ディスプレイ用に設計されており、DisplayPort 1.2 を HDMI 2.0 に変換するための製品です。したがって、HDR 技術に対して互換性がありません。
もしこのアダプターを使って HDR 対応テレビを接続すると、テレビ側は HDR 機能を有効にしようとするため、結果としてリフレッシュレートが下がり、表示品質が低下することがあります。一部のテレビは HDR 機能を無効にする設定ができますが、常に HDR を優先して有効化しているテレビもあります。その場合はリフレッシュレートの低下を避けることはできません。

Can I Connect a DisplayPort (DP) Monitor to the HDMI Port on This Device Using an Adapter or Cable?
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.
No Sound? How to Change Your Default Audio Device to Your Plugable Product
Whether you're on Windows, macOS, or Linux, it's common to add new audio devices to your computer.
Some examples of additional audio devices you may want to switch to include:
- Bluetooth headsets, headphones, and speakers
- Speakers built into a display, such as a TV or monitor
- A USB sound card, digital audio converter (DAC), or analog to digital converter (ADC)
- USB microphones
- Audio jacks on a docking station
These steps don't apply to the Plugable Performance NIX HDMI Capture Card (USBC-CAP60).
Here are the steps that you need to set a new default audio recording or output device on different operating systems.

What’s the Difference Between an Active and Passive DisplayPort Adapter?
DisplayPort to HDMI/DVI/VGA conversion is deceptively complex because the two standards use different electrical signaling. DisplayPort comes in two versions—"Dual Mode" DisplayPort (DP++), which allows the port to actually switch its electrical signaling to a different format, and "pure" DisplayPort (DP), which is intended for DisplayPort monitors without any conversion.
Passive adapters rely entirely upon DP++ functionality to produce the appropriate output signal. In other words, passive adapters do not work when connected to a regular DisplayPort port (only supported through a DP++ port).
Active adapters on the other hand contain extra components that perform the necessary signaling conversion on their own, so they do not have the same reliance on a DP++ port as a passive adapter would. In other words, active adapters are more flexible and can be used on either a pure DisplayPort output or a DP++ port. To hit the point home, passive adapters only work through DP++ ports.
My Docking Station/Adapter Works Well With My Windows Laptop, but When I Close the Lid the Displays and Laptop Turn Off or Sleep. How Do I Fix This?
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:
- Start by right-clicking on the Start button and select Power Options from the menu.
- From the right side of the Power Options settings page, select the blue link for Additional power settings
- From the choices present on the left-hand side of the Power Options window, please click on Choose what closing the lid does
- Make sure the setting for When I close the lid under the Plugged In column is set to Do Nothing
- 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:
- Start by right-clicking on the Start button and select Power Options from the menu.
- 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
- Make sure the setting for When I close the lid under the Plugged In column is set to Do Nothing
- 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 )
