DisplayPort 1.4 is the most wanted connection for high-resolution games and professional display setups. A guide from one end to another, the very essence of advanced display technology.
What is DisplayPort 1.4?
VESA (Video Electronics Standards Association) is a company that is responsible for the development of DisplayPort 1.4—a digital display interface. This standard changed the way we connect computer monitors and display units of gaming systems since its introduction in March 2016.
One side of the rectangular DisplayPort connection is tilted. This special design not only gives users an easy way of identifying the connectors but also ensures the correct orientation of the connection. Compared to USB ports, which come in different sizes, the DP port is a bit bigger and also has a small part that locks the connector securely in place.
Main Technical Specifications
DisplayPort 1.4 is a high-bandwidth display interface delivering significant efficiency values that improve its competitive display standards:
- Maximum total bandwidth: 32.4 Gbps
- Maximum data rate: 25.92 Gbps
- Support for 4K resolution at 120Hz with 24-bit color
- 5K display support at 60Hz with 30-bit color
- 8K video capability at 30Hz
These specs make DP 1.4 the best version for high-performance applications where you cannot compromise on the visual quality.
DisplayPort 1.4 vs HDMI 2.0: The Ultimate Comparison
The matter of ‘who is the best’, DisplayPort or HDMI 2.0, is a hot discussion that is still very hot, and it typically depends on the particular circumstances and the requirements to be met.
Bandwidth Comparison
DisplayPort 1.4 has a bandwidth of 32.4 Gbps, while HDMI 2.0 has only 18 Gbps. This large gap is reflected in the better performance of the configurations of the same resolution and faster refresh rates.
Gaming Performance
For PC gaming, DisplayPort 1.4 vs HDMI for 4K gaming offers better performance. The increased bandwidth allows gaming at a higher level, for example:
- High refresh rate displays (144Hz, 240Hz)
- Multi-monitor setups
- Display Stream Compression for enhanced visual quality
- Better HDR support
Professional Applications
Graphic designers and video editors are people who always need to use DisplayPort connections, as the reliability of these and performance are what they value the most. The stable connection and high data transfer speeds guarantee flawless color reproduction and a light work process.
Understanding Display Stream Compression (DSC)
The DisplayPort 1.4 topmost feature is undoubtedly DSC 1.2. DSC is what makes visually lossless encoding of the high-resolution content possible.
Benefits of DSC Technology
DSC enables DisplayPort 1.4 to:
- Run 4K at 120Hz with HDR and 30-bit color
- Work at 8K 60Hz
- Reduce bandwidth usage without loss of quality
- Give better performance to visually demanding applications
This technology has compression at its core, thus even the most demanding content is displayed perfectly without any sacrifice in visual fidelity.
DisplayPort 1.4 Cable Selection Guide
Picking the right DisplayPort 1.4 cable is very important for the best performance. Not every cable is the same, and a VESA-certified choice provides assurance.
Cable Length Considerations
- Passive cables: Best for distances up to 6 feet
- Active cables: Need longer runs up to 24 feet
- Signal integrity: Active components might be necessary if cables are long
Quality Indicators
Use these factors to find the most suitable DisplayPort 1.4 cables:
- VESA certification mark
- Full 32.4 Gbps bandwidth support
- 8K resolution compatibility labels
- Connector made of premium materials
Premium quality conductors guarantee the highest signal quality and enable the full potential of all resolutions and refresh rates to be utilized without any compatibility issues or performance problems.
DisplayPort 1.4a: Improved Compression Method
DisplayPort 1.4a is the reincarnation of the standard from April 2018 with a small but important revision in the main features. The update is mainly focused on the support of the dynamic source compression (DSC) in general.
Main Differences Between DP 1.4a and DP 1.4
Although DP 1.4 has given the go-ahead for the DSC feature, in reality, it has not been included in each implementation. On the other hand, DP 1.4a is the perfect inheritor of DSC 1.2a all over the place.
Better HDR Support
DSC 1.2a is the one driving the new HDR compression tricks, which facilitate the colors to be more precise and the visual part to be more pleasing to the eyes when it comes to HDR.
Simplified Ecosystem
Universal DSC support keeps the users guaranteed, with no need to worry about the features that are available on their devices. Every single DisplayPort 1.4a ensures the presence of a compression feature along with a capability that makes choosing the device easier.
