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.

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 )

Firmware Update for 4K 120Hz Support on Apple Silicon MacBooks (macOS 26+)
macOS 26 Tahoe introduced support for high refresh rate modes for compatible HDMI 2.1 displays on compatible Apple Silicon Mac systems. Plugable adapters with compatible chipsets, such as USBC-HDMI8K and UD-7400PD, support these higher modes if the adapter is running the correct firmware. Please also note that high refresh rate is not available on all displays. Consult your monitor’s user manual to check what it supports
System Requirements
HDMI 2.1 high refresh rate support is available only on the following Apple Silicon Mac processors:
- M1 Pro
- M1 Max
- M2 Pro
- M2 Max
- M3 and newer
Base M1 and base M2 systems do not support HDMI 2.1 high refresh rate output. On these systems, 4K high refresh rate modes will not be available.
Note that if 4K high refresh rate modes are not available in System Settings > Displays, your unit may require updated firmware to enable this functionality. Without the updated firmware, the adapter may operate in HDMI 2.0 mode and high refresh rate options may not appear, even when using:
- macOS 26 Tahoe or above
- A compatible HDMI 2.1 display
- A HDMI 2.1 cable
- A supported Pro/Max or M3+ Mac system
What You Need
To update the firmware, you will need:
- A HDMI 2.1 Cable
- A Windows PC with a USB-C port that supports DisplayPort Alt Mode (video output)
- The VmmTool firmware update application: https://apps.microsoft.com/detail/9nrk6tg8vcnx?hl=en-US&gl=US
- The appropriate firmware (.fullrom) file
Note: The firmware update cannot be performed in macOS. A Windows system with USB-C DisplayPort Alt Mode support is required. Please contact Plugable support at support@plugable.com if you don’t have access to a system for performing the update.
How to Update
To ensure the best possible experience we ask that you contact our support team directly to request the firmware update instructions. Please contact Plugable support at support@plugable.com.
Can I use an Alt Mode video adapter with my Mac?
Most modern MacBooks with USB-C, USB4, or Thunderbolt 3/4 ports support Alt Mode-based video adapters, making them compatible with Plugable Alt Mode video adapters. This includes:
- MacBook Pro (2016 and later)
- MacBook Air (2018 and later)
- Mac Mini (2018 and later)
- iMac (2017 and later)
- Mac Studio
Important Note:
M1, M2, M3, and newer MacBooks support only one external display via Alt Mode (with exceptions for the MacBook Pro 14-inch and 16-inch with M1 Pro/Max, M2 Pro/Max, M3 Pro/Max). If you need multiple external displays for a Mac with a base M1, M2, or M3 chip, consider Plugable’s USB Graphics Adapters instead.
How To: Set the Display Refresh Rate in Windows 11
Many modern displays can support above the default 60Hz refresh rate, however this may need to be manually set within Windows 11. Please note, not all computers, graphics adapters, and docking stations can support all resolutions and refresh rates.
Setting the Display Refresh Rate in Windows 11
1. Right-click on the desktop and select Display Settings from the drop-down menu

2. Scroll down to the Related settings subsection and select Advanced display

3. At the top of the Advanced display window, select the external display from the drop-down menu

4. From the Choose a refresh rate drop-down menu select the desired refresh rate

Refresh Rate Limitations
With Windows 24H2 and newer, dynamic refresh rates are supported, this allows the system to adjust the display refresh rate to save power, up to the selected refresh rate. As a consequence of this new mode, when selecting the display refresh rate you may see an asterisk. This indicates that selecting the specific refresh rate may reduce the display resolution or image quality in order to prioritize the refresh rate. This exposes the refresh rate option from the display even if the display cable or computer is incapable of supporting that refresh rate at the native resolution and is the intended behavior per Microsoft. [1]
In the screenshot below the left side shows the 4K 120Hz capable display limited to 60Hz refresh rate without asterisks, and on the right the same display after setting the refresh rate to “120 Hz*”, the “Desktop mode” resolution has been reduced to 2560 x 1440 (1440p) instead of 3840 x 2160 (4K UHD). Unlike when using the display scaling option this also causes a reduction in image quality. On the right side asterisks are no longer shown in the refresh rate list. Setting the refresh rate back to 60Hz does not change the resolution, you will have to go back one page and set the resolution manually.

Understanding External Display Support on Apple M1, M2, M3, M4 and M5 Chips
Apple's M1, M2, M3, M4 and M5 chips deliver high performance, but each generation has unique capabilities for supporting external displays via the system’s Thunderbolt ports. This article explains how many displays each chip can support while directly connected to the laptop, and will assist you in identifying if a software solution (DisplayLink, InstantView, etc.) is needed. This article largely applies to the MacBook Air and MacBook Pro models. Other Apple models, such as the Mac Mini and iMac may have similar display restrictions, but always check your specific device's documentation for confirmation.
Important Note: Native Display Limits
Even if you connect a Thunderbolt dock or adapter, extended displays cannot exceed what is natively supported by the Thunderbolt ports on your Mac device.
- Example: A MacBook with a base M1 or M2 CPU supports only one external display via Thunderbolt. Adding a Thunderbolt dock will not increase this limit due to hardware constraints.
- In several cases of the ‘Max’ variation of CPU, multiple Thunderbol ports must be used in order to connect mutliple displays. This can be done utilizing all Thunderbolt ports for a single display, or using a Thunderbolt dock to connect up to two of the displays.
- Plugable offers alternative solutions, such as USB DisplayLink technology-based docks and adapters, which allow for additional displays on devices with limited native support. This technology combines software and hardware to send video signals over USB data connections.

How to Determine Your USB-C Port Video Capabilities
under
Understanding your laptop's video output capabilities is essential when connecting to external displays. This guide will help you identify what video technologies your laptop supports and how to find the relevant information.
Common Video Output Technologies
Modern laptops commonly use one or more of the following technologies to transmit video to external monitors:
1. Thunderbolt 3
- Supports video output using the DisplayPort protocol.
- Capable of driving up to two 4K displays at 60Hz or one 5K display at 60Hz.
- Uses a USB-C connector and features a lightning bolt symbol next to the port.
Note: An example of Thunderbolt 3 ports
2. Thunderbolt 4
- Provides improved performance over Thunderbolt 3.
- Supports up to two 4K displays at 60Hz or one 8K display.
- Uses a USB-C connector with the same lightning bolt symbol but may also include the number "4" for identification.
Note: Thunderbolt 4 has the same physical connection and “lightning” bolt icon as Thunderbolt 3
3. Thunderbolt 5 (As of 2024)
- Up to 80 Gbps bi-directional bandwidth (Double that of Thunderbolt 4’s 40 Gbps).
- Up to 120 Gbps bandwidth for displays (With Bandwidth Boost — 120 Gbps upstream and 40 Gbps downstream for display-intensive use cases).
- Support for dual 6K or 8K displays (Compared to Thunderbolt 4’s dual 4K support).
4. USB-C DisplayPort "Alt Mode"
- Allows video output directly through the USB-C port using DisplayPort technology.
- Commonly supports one 4K display at 60Hz, but capabilities may vary.
- Often marked with a DisplayPort ("DP") symbol, but this feature may also be specified in your system's documentation.
Note: An example of a USB-C port with DisplayPort capabilities
How to Identify Your Laptop's Video Capabilities
To determine what video technologies your laptop supports, follow these steps:
1. Check Your Laptop's User Manual:
- Locate your laptop's user manual (often available online from the manufacturer's support site).
- Search for keywords like "Thunderbolt," "DisplayPort Alt Mode," or "video output capabilities."

2. Visit the Manufacturer's Website:
- Go to the support page for your laptop model and find the technical specifications section.
- Look for details on Thunderbolt or USB-C video capabilities.

3. Inspect Your Laptop's Ports:
-
Check for identifying symbols next to USB-C ports:
- Thunderbolt 3/4 ports may have a lightning bolt symbol.
- DisplayPort Alt Mode may be marked with a "DP" icon.
“What if I do not have the above technologies?”: USB 3.0 (Type-A) and Display Expansion
While USB 3.0 (Type-A) ports do not support native video output, they can still be used to extend to two or more displays using software-based solutions like DisplayLink or Silicon Motion's InstantView. These technologies enable video through USB-A ports by utilizing dedicated drivers and software.
If your laptop lacks Thunderbolt or USB-C video capabilities, DisplayLink or InstantView may be a viable alternative for expanding your display setup. A few other things to consider:
- Not all USB-C ports support video output. Checking your laptop's documentation is crucial to confirm this capability.
- Thunderbolt ports are backward compatible with USB-C DisplayPort Alt Mode but provide enhanced performance and flexibility.
If you have further questions about connecting your Plugable docking station or adapter to your laptop, please reach out to our support team for guidance.
What Video Output Conversions Are Possible?
When connecting displays across different ports—USB-C, HDMI, DisplayPort, DVI, and VGA—some conversions are possible, while some are not practically possible with simple adapters. Here’s a quick guide to what you can and can’t do when adapting video output formats.
Compatible Video Output Conversions
USB-C to:
HDMI – Supported
DisplayPort – Supported
DVI – Supported
VGA – Supported
Tip: Ensure your USB-C port supports DisplayPort Alt Mode for video output compatibility.
DisplayPort to:
HDMI – Supported via passive adapters or cables (if the source supports DP++), or via active adapters (if the source does not support DP++)
USB-C – Supported, but requires a bidirectional USB-C to DisplayPort adapter
DVI – Supported using an active DisplayPort to DVI adapter.
HDMI to:
DVI – Supported
VGA – Requires an active HDMI to VGA adapter (HDMI is digital, VGA is analog).
Incompatible or Limited Conversions
Not all conversions are technically or electrically possible, especially when going “backward” from digital standards to analog or from display-focused outputs to data-centric inputs.
These will not work without practically without more complex adapters:
HDMI to DisplayPort – Requires an active HDMI to DisplayPort adapter, which can have mixed results
HDMI, VGA, or DVI to USB-C – Not supported
VGA to HDMI, DVI, or DisplayPort – Being analog, VGA needs active conversion to work with digital video standards like HDMI or DisplayPort.
Understanding Uni-Directional vs. Bi-Directional Video Cables
When connecting a laptop/dock to a monitor, the right direction matters. Many “converter” cables only work one way. If the cable’s intended direction doesn’t match your source (video output) and display (video input), you’ll get no signal. Even if the connectors fit.
Key terms
- Source (Output): Laptop, dock, GPU port sending video
- Display (Input): Monitor/TV/projector receiving video
- Uni-directional: Works only one way (e.g., DP to HDMI)
- Bi-directional: Works both ways (common with HDMI to/from DVI, DP to/from mDP)
- Active adapter: Has electronics to convert formats/directions (e.g., HDMI to DP)
- Passive adapter/cable: No electronics; relies on source capabilities (e.g., DP++ to HDMI)
What typically works and what doesn’t
Scenario |
Directionality |
Requirement |
Notes |
DisplayPort (DP) source to HDMI display |
Often uni-directional (DP to HDMI) |
Passive may work with DP++; otherwise use an active DP to HDMI |
Many docks/GPUs support DP++, but some do not so please check specification |
HDMI source to DisplayPort display |
Uni-directional (HDMI to DP) |
Active HDMI to DP adapter |
A DP to HDMI cable won’t work in reverse. |
USB-C (DP Alt Mode) source to HDMI/DP display |
Uni-directional |
Alt-Mode USB-C to video cable/adapter |
Not reversible (you can’t feed HDMI into USB-C). |
Thunderbolt 3/4 source to HDMI/DP display |
Uni-directional |
TB/USB-C video adapter |
Behaves like USB-C Alt Mode for displays. |
HDMI to/from DVI |
Bi-directional (passive) |
Simple adapter/cable |
Same TMDS signaling. |
DP to/from Mini-DP |
Bi-directional (passive) |
Simple cable |
Same protocol. |
Digital to/from VGA (analog) |
Direction varies |
Active converter |
Digital/analog conversion required. |
Rule of thumb: For DP to/from HDMI, assume DP to HDMI unless the product explicitly says HDMI to DP (Active).
Docking stations: quick notes
- USB-C/Thunderbolt docks output standard HDMI/DP signals (direction rules above still apply)
- DisplayLink-based docks still output HDMI/DP at the port (same direction rules)
- DP MST/daisy-chain works only in DP domain; converting to HDMI at the first hop ends DP-specific features downstream
Resolution, refresh, and features
- Achievable resolution/refresh (e.g., 4K60) depends on source + cable/adapter + display
- Features like HDR, HDCP, and VRR may require active adapters and sufficient bandwidth
- For long runs or flaky links, prefer active solutions
Shopping checklist (esp. on Amazon)
- Check the pictures: Listings often show Source to Display with icons/arrows (match this to your setup)
- Read the title/bullets: Look for explicit direction (“DP to HDMI,” “HDMI to DP (Active)”)
- Scan specs: “Active” vs. “Passive,” DP++, supported resolutions, and any power needs
Quick examples
- Dock (DP out) to Monitor (HDMI in): DPtoHDMI cable/adapter; use active if DP++ isn’t supported or for higher reliability
- Laptop (HDMI out) to Monitor (DP in): Active HDMItoDP adapter required
- USB-C laptop (Alt Mode) to HDMI monitor: USB-CtoHDMI cable/adapter; not reversible
FAQs
Why doesn’t my “DP to HDMI” cable work from an HDMI laptop to a DP monitor?
It’s uni-directional (DP to HDMI). Your path is the reverse and needs an active HDMI to DP adapter.
Are “bi-directional” cables truly both ways?
Commonly for HDMI to/from DVI and DP to/from mDP. For DP to/from HDMI, true bi-directional products are uncommon—verify the exact directions in the listing images/text.
Update Graphics Drivers in Windows
Up to date graphics drivers are necessary for ensuring the best performance of your computer's built-in display, as well as the capability and compatibility with external displays and docking stations.
Windows has a built-in system update service: Windows Update, however this may not provide up to date drivers or timely updates. We often see systems with out of date drivers, in some cases systems may not receive updated graphics drivers for months or even years, leaving the computer with drivers incompatible with the installed version of Windows 11.
However, we can manually update the graphics drivers to ensure the best possible performance, reliability, and compatibility.
The first step is to identify the graphics hardware, then downloading, and installing the latest drivers.
Identifying Graphics Controller
For notebooks and many desktop computers, the primary graphics controller is embedded in the processor, both AMD and Intel provide graphics driver updates based on the processor model, as well as for discrete graphics controllers. Our first step is to identify up the processor or graphics hardware model details:
- Right-click on the Start Menu and select Settings from the pop-up menu
- From the left column select System and from the bottom of the right side select About
- From the top of the about page the processor details will be on the right side, and duplicated lower down on the page.
- In this example the processor is a 12th Gen Intel(R) Core(TM) i7-1260P, we'll keep that detail for the next step.
If your computer has two graphics controllers (it may show "Multiple GPUs Installed" under Graphics Card) then we can get the graphics card model details from the Windows System Information Utility.
- Open the Start menu and search for "msinfo32"
- Select the first result
- From the left-column expand the Components section, then select Display
- In this example the Intel Iris(R) Xe Graphics is enabled by the processor, while the Intel(R) Arc(TM) Pro B60 Graphics is a discrete graphics controller.
Downloading the Drivers
Intel Graphics
- In a web browser navigate to the Intel Driver Download Page
- In the "Search Drivers & Software" field, search for the Intel graphics card model or CPU model, "Arc Pro B60" in this example
- Select the appropriate "Intel Arc Pro Graphics - Windows" or similar entry from the search results, for modern hardware Intel will normally have at least one release per month, the list should return recent results within the last month
- Select the Download button to save the installer to your Downloads folder or selected location
AMD Graphics
AMD provides an Auto-Detect utility, this works relatively well and can be used to update the system available from the AMD Drivers and Support page.
This page also provides a search and browse option for finding drivers and specific compatibility details, we'll look up the drivers for an AMD Ryzen Pro 5650U processor with Radeon Graphics:
- Navigate to AMD Drivers and Support page
- From the Browse section, fill out the processor details and click the Submit button
- Expand the "Windows 11 - 64-Bit Edition" section and select the Download button for the latest graphics drivers
NVIDIA Graphics
Like AMD, NVIDIA provides an automatic installation utility, as well as a Manual Driver Search on the NVIDIA Drivers support page. We will look up the drivers for an NVIDIA RTX 5080 graphics card.
- Navigate to NVIDIA Drivers support page
- Fill out the Manual Driver Search drop-downs and select the "Find" button when complete
- From the search results, select the "View" button for the GeForce Game Ready Driver or NVIDIA Studio Driver (if you need the studio driver features)
- Select the green Download button for the latest graphics drivers
Installing the Graphics Drivers
For the most part this is relatively simple, we recommend disconnecting any external docking stations or devices that are not necessary for the driver installation, and for notebook computers connecting the system's original power supply.
Double-click on the downloaded driver installation executable and follow the on screen steps.
