We’ll take a closer look at the key features, enhancements, advantages, and notable improvements of each version, as well as how to visually identify the cable versions, check manufacturers’ specifications, and use software to determine the DisplayPort version. Let’s get started on demystifying DisplayPort cables!
What Is Displayport Cable?
The DisplayPort cable is a digital video and audio interface commonly used in electronic devices such as laptops, desktop computers, monitors, and televisions. It provides a high-definition and high-quality connection between the source device and the display device. DisplayPort technology was developed by the Video Electronics Standards Association (VESA) and first introduced in 2006 as an alternative to existing video interface standards.
The DisplayPort cable is designed to transmit video, audio, and other data simultaneously over a single cable. It uses a packet-based protocol that allows for high-bandwidth video and audio transmission, supporting resolutions up to 8K and refresh rates up to 240Hz. Compared to other video interfaces like HDMI or DVI, DisplayPort offers higher performance, better flexibility, and increased compatibility.
The first version of DisplayPort, known as DisplayPort 1.0, was initially introduced with a maximum data transfer rate of 8.64 Gbps. Over the years, newer versions have been released, each with improved features and capabilities. These versions include DisplayPort 1.1, 1.2, 1.3, 1.4, and the latest version, DisplayPort 2.0.
Why Is It Important To Identify The Version?
When it comes to display cables, one important aspect that often gets overlooked is identifying the version of the cable being used. Knowing the specific version of a displayport cable is crucial as it can directly impact the capabilities and compatibility of your display setup.
The displayport cable comes in various versions, each with its own set of features and capabilities. These versions include DisplayPort 1.1, 1.2, 1.3, and the latest version, DisplayPort 2.0. Identifying the version is essential because it determines the maximum resolution, refresh rate, and other features that your cable can support.
The first step in identifying the displayport cable version is to inspect the physical connectors on both ends of the cable. DisplayPort cables have 20 pins arranged in two rows. By counting the pins and comparing them to a reference image, you can get a rough idea of the cable version. However, this method might not be entirely accurate, especially if the cable is not labeled or if the pins are not easily visible.
A more reliable method is to check the labeling and certification logos on the cable. Look for the official DisplayPort logo, which indicates that the cable has undergone testing and certification by the DisplayPort consortium. Additionally, some cables may have the version number clearly labeled, making it easy to identify the cable version.
- Inspect the physical connectors
- Count the pins or compare with reference image
- Check for labeling and certification logos
- Look for version number
|Maximum Refresh Rate
|2560 x 1600
