As technology advances, it’s essential to stay up-to-date with the latest features and capabilities of your devices. One crucial aspect of modern computing is the DisplayPort, a digital video interface that enables the connection of high-resolution displays, projectors, and other devices. But with multiple versions of DisplayPort available, how do you know which one your device has? In this article, we’ll delve into the world of DisplayPort, exploring its history, versions, and most importantly, how to identify the DisplayPort version on your device.
The Evolution of DisplayPort
DisplayPort, developed by the Video Electronics Standards Association (VESA), was first introduced in 2007 as a digital video interface standard. The initial version, DisplayPort 1.0, offered a maximum bandwidth of 8.64 Gbps, supporting resolutions up to 2560×1600 at 60 Hz. Since then, DisplayPort has undergone significant upgrades, with each subsequent version introducing new features, higher bandwidth, and increased capabilities.
DisplayPort Versions: A Brief Overview
Before we dive into identifying DisplayPort versions, let’s take a quick look at the different versions available:
- DisplayPort 1.0: Released in 2007, this version supports resolutions up to 2560×1600 at 60 Hz with a maximum bandwidth of 8.64 Gbps.
- DisplayPort 1.1: Introduced in 2009, this version increased the maximum bandwidth to 17.28 Gbps, enabling support for resolutions up to 4096×2160 at 60 Hz.
- DisplayPort 1.2: Released in 2010, this version further increased the bandwidth to 21.6 Gbps, allowing for resolutions up to 5120×2880 at 60 Hz.
- DisplayPort 1.3: Launched in 2014, this version boasted a maximum bandwidth of 32.4 Gbps, supporting resolutions up to 5120×2880 at 120 Hz or 4096×2160 at 144 Hz.
- DisplayPort 1.4: Introduced in 2016, this version increased the bandwidth to 40.8 Gbps, enabling support for resolutions up to 5120×2880 at 240 Hz or 7680×4320 at 60 Hz.
- DisplayPort 2.0: The latest version, released in 2019, offers an incredible maximum bandwidth of 80 Gbps, supporting resolutions up to 15360×8640 at 60 Hz or 7680×4320 at 240 Hz.
Identifying Your DisplayPort Version
Now that you’re familiar with the various DisplayPort versions, let’s explore the ways to identify which version your device has.
Check the Device Documentation
The simplest way to determine your DisplayPort version is to consult your device’s documentation, such as the user manual or technical specifications. This information is usually readily available online or in the device’s packaging.
Inspect the DisplayPort Connector
Take a closer look at the DisplayPort connector on your device. The connector’s design and layout can give you an idea of the version:
- DP 1.0 and 1.1: These versions have a rectangular connector with a single lane.
- DP 1.2 and 1.3: These versions feature a slightly modified connector with two lanes.
- DP 1.4 and 2.0: These versions have a more pronounced difference, with four lanes and a slightly larger connector.
However, keep in mind that this method is not foolproof, as some devices may use a compatible connector design even if they don’t support the latest version.
Check the Device Manager (Windows) or System Information (macOS)
On Windows devices, follow these steps:
- Press the Windows key + X and select Device Manager.
- Expand the “Display Adapters” section.
- Right-click on the DisplayPort adapter and select “Properties.”
- In the Properties window, look for the “DisplayPort Version” or “DisplayPort Capability” section.
On macOS devices, follow these steps:
- Click the Apple logo in the top left corner and select “About This Mac.”
- Click the “System Report” button.
- In the System Report window, scroll down and select “Hardware” in the left sidebar.
- Click on “Displays” and look for the “DisplayPort” section.
Use Third-Party Software
Several third-party software tools can help you identify your DisplayPort version. Some popular options include:
- GPU-Z (Windows): A free utility that provides detailed information about your graphics card, including the DisplayPort version.
- HWiNFO (Windows): A comprehensive system monitoring tool that includes information about your DisplayPort version.

What is DisplayPort and how does it differ from other display interfaces?
DisplayPort is a digital display interface developed by the Video Electronics Standards Association (VESA) that is designed to connect computers and other devices to displays and monitors. It is different from other display interfaces such as HDMI, DVI, and VGA in that it has a higher bandwidth and can support multiple displays and higher resolutions.
DisplayPort is also capable of transmitting audio and other data in addition to video, making it a more versatile and convenient option for connecting devices. Additionally, DisplayPort is designed to be a more scalable and future-proof technology, making it well-suited for use with high-resolution and high-refresh-rate displays.
How do I identify the DisplayPort version on my device?
To identify the DisplayPort version on your device, you can check the device’s documentation, manufacturer’s website, or the device’s packaging for the DisplayPort version number. You can also check the device’s ports and connectors for a label or marking that indicates the DisplayPort version.
Alternatively, you can also check the device’s settings or control panel to see if it displays information about the DisplayPort version. For example, on a Windows device, you can check the Device Manager or the Display settings to see if it lists the DisplayPort version.
What are the different versions of DisplayPort and their capabilities?
There have been several versions of DisplayPort released, each with its own set of capabilities and features. DisplayPort 1.0 was the first version, which supported resolutions up to 2560×1600 at 60Hz. DisplayPort 1.1 increased the maximum resolution to 4096×2160 at 60Hz, while DisplayPort 1.2 introduced Multi-Stream Transport (MST) to support multiple displays on a single connection.
DisplayPort 1.3 and 1.4 further increased the maximum resolution and bandwidth, adding support for 5K and 8K resolutions at higher refresh rates. The latest version, DisplayPort 2.0, supports resolutions up to 16K at 60Hz and introduces new features such as improved HDR and augmented reality (AR) support.
Can I use a DisplayPort cable with a different version than my device?
In general, a DisplayPort cable is backwards compatible, meaning that a cable with a higher version number can be used with a device that has a lower version number. However, the maximum bandwidth and capabilities of the connection will be limited to those of the device with the lower version number.
For example, if you have a DisplayPort 1.4 device and use a DisplayPort 2.0 cable, the maximum resolution and bandwidth will be limited to those of DisplayPort 1.4. It’s generally recommended to use a cable that matches the version of your device to ensure optimal performance and compatibility.
What is Multi-Stream Transport (MST) and how does it work?
Multi-Stream Transport (MST) is a feature introduced in DisplayPort 1.2 that allows multiple independent displays to be connected to a single DisplayPort connection. MST works by allowing the display controller to split the DisplayPort signal into multiple streams, each of which can support a separate display.
Each display connected to the MST hub receives its own stream of data, allowing for multiple displays to be connected and operated independently. MST is useful for applications such as gaming, video editing, and office work, where multiple displays are needed to increase productivity and efficiency.
What is the difference between a passive and active DisplayPort adapter?
A passive DisplayPort adapter is a simple adapter that physically converts a DisplayPort connector to another type of connector, such as HDMI or DVI. Passive adapters do not actively convert the signal and rely on the device’s built-in conversion capabilities.
An active DisplayPort adapter, on the other hand, contains active electronics that convert the DisplayPort signal to another type of signal, such as HDMI or DVI. Active adapters can support higher resolutions and bandwidths than passive adapters and are more likely to work with devices that do not have built-in conversion capabilities.
Can I use a DisplayPort connection to connect my device to a USB-C port?
Yes, it is possible to use a DisplayPort connection to connect your device to a USB-C port. Many modern devices have USB-C ports that support DisplayPort Alternate Mode (DP Alt Mode), which allows the USB-C port to carry a DisplayPort signal.
To use a DisplayPort connection with a USB-C port, you will need a USB-C to DisplayPort adapter or cable that supports DP Alt Mode. Keep in mind that not all USB-C ports support DP Alt Mode, so you should check your device’s documentation to ensure compatibility.
