This article illuminates their differences – from release dates, bandwidths and data bit rates to resolution capacities – empowering you with the information required to make an informed choice based on your usage needs.
What is DisplayPort?
DisplayPort is a digital display interface primarily used to connect a video source like a computer or gaming console, to a display device such as a monitor, TV, or projector. It’s developed by the Video Electronics Standards Association (VESA) and can transmit both audio and video signals.
DisplayPort offers high resolutions with higher refresh rates making it the preferred choice for high-end monitors and graphics cards.
With its ability to deliver 4K resolution at 60Hz, DisplayPort 1.2 still has more bandwidth than most HDMI standards further solidifying its position in the market.
However, technology doesn’t stand still.
The introduction of DisplayPort 1.4 took capabilities even further with increased maximum total bandwidth reaching up to 32.40 Gbps and data rate peaking at 25.92 Gbps supporting even larger resolutions while maintaining high refresh rates of over 120Hz at native 4K resolution using HDR10 standard compatibility for more vibrant visuals.
Key Differences between DisplayPort 1. 2 and 1. 4
DisplayPort 1.2, an innovation delivered in 2009, revolutionized the scene with its superior bandwidths and refresh rates outperforming older standards like DVI and VGA.
Fast forward to seven years later, DisplayPort 1.4 was launched in 2016 introducing striking upgrades from its predecessor: it not only embraced progressive monitor resolutions up to 8K but also boasted higher refresh rates.
This newer version of DisplayPort enabled users to experience visuals with absolute clarity and unparalleled smoothness on their displays.
Interestingly, three years after the introduction of DisplayPort 1.4, the industry saw another significant advancement with the emergence of DisplayPort 2.0 in 2019 that further expanded support for leading-edge resolutions.
Resolutions and refresh rates
DisplayPort 1.2 and 1.4 significantly differ in their support for resolutions and refresh rates, with the latter coming on top. DisplayPort 1.2 supports up to 4K (3840×2160 pixels) at a refresh rate of 60Hz, providing the necessary bandwidth for most mainstream uses today.
Stepping into higher-end territory, DisplayPort 1.4 offers enhanced capabilities including support for stunning visuals up to a resolution of 8K (7680×4320 pixels) at a sedate refresh rate of up to 30Hz or more dynamic displays like gaming monitors featuring full HD (1080p) with an astounding refresh rate up to 240Hz or even high-resolution monitors sporting a resolution of 1440p at a smooth-ticking rate of upto240Hz; all these revolutionary specs meeting every professional and gamer’s needs alike!
Notably, it also includes the feature “Display Stream Compression” that enables high HDR quality content without compromising color depths resulting in visually stunning imagery making this version stand distinctively ahead compared to its predecessor – The Port cabled Displayport version- DP1.2.
Bandwidths and data bit rates
DisplayPort 1.2 and 1.4 differ in terms of bandwidths and data bit rates.
