In this article, we’ll delve into the world of DisplayPort, exploring its history, features, and benefits, to help you make an informed decision.
A Brief History of DisplayPort
DisplayPort is a digital video interface standard developed by the Video Electronics Standards Association (VESA). First introduced in 2006, DisplayPort was designed to replace VGA, DVI, and other older display interfaces. The initial version, DP 1.0, supported a maximum bandwidth of 10.2 Gbps, allowing for resolutions up to 2560×1600 at 60 Hz.
Over the years, DisplayPort has undergone several revisions, each introducing new features and improvements. Some notable milestones include:
- DP 1.1 (2007): Added support for multiple display streams and increased bandwidth to 21.6 Gbps.
- DP 1.2 (2010): Introduced Multi-Stream Transport (MST) and increased bandwidth to 21.6 Gbps.
- DP 1.3 (2014): Increased bandwidth to 32.4 Gbps and added support for 5K resolutions.
- DP 1.4 (2016): Introduced Display Stream Compression (DSC) and increased bandwidth to 32.4 Gbps.
What’s New in DP 1.4?
DP 1.4 is the latest iteration of the DisplayPort standard, offering several significant improvements over its predecessors. Some of the key features and benefits of DP 1.4 include:
Display Stream Compression (DSC)
DSC is a visually lossless compression algorithm that enables the transmission of higher resolutions and refresh rates over existing DisplayPort cables. This technology allows for the compression of display data, reducing the required bandwidth and enabling the support of higher resolutions.
Increased Bandwidth
DP 1.4 offers a maximum bandwidth of 32.4 Gbps, allowing for the support of higher resolutions and refresh rates. This increased bandwidth enables the transmission of:
- 5K resolutions (5120×2880) at 60 Hz
- 4K resolutions (3840×2160) at 120 Hz
- 1080p resolutions (1920×1080) at 240 Hz
Multi-Stream Transport (MST)
MST is a technology that enables the transmission of multiple independent display streams over a single DisplayPort cable. This allows for the support of multiple monitors, each with its own unique resolution and refresh rate.
Forward Error Correction (FEC)
FEC is a technology that enables the detection and correction of errors that occur during data transmission. This ensures that display data is transmitted accurately and reliably, reducing the risk of errors and artifacts.
Benefits of DP 1.4
DP 1.4 offers several benefits over older DisplayPort versions, including:
Higher Resolutions and Refresh Rates
DP 1.4’s increased bandwidth and DSC technology enable the support of higher resolutions and refresh rates, making it ideal for applications that require high-performance displays.
