Evolution is part of the DNA of every living being. It is also part of the industrial to technological advancements. Even if you find the sports the same as they were when they were invented, their rules, jerseys, and other mediums for sports accessories are continually evolving.
Let’s revamp a bit and give credit to the VGA cables that have pioneered the evolution of today’s display connectivity since their introduction by IDM in 1987. In 30+ years, we now have HDMI and DP cables, all thanks to the contributions of these cables. Let’s explore that further:
The VGA Standard: A Pioneering Legacy
The Video Graphics Array (VGA) was the first cable type and display port type that was adopted as the industrial standard for technology. It became the standard for all the display units available worldwide. Even today, they have the iconic 15-pin connector that has a blue shell around it, which makes it stand out.
It was first used to connect with Cathode Ray Tube (CRT) Monitors. But with LCD and LED monitors, the VGA ports and the cables were still prevalently used. However, they turned into a revolution for analog video transmission. Even today, the display monitors, even for gaming and graphics or simple entertainment, come with compatibility to a vga to vga cable.
HDMI: The Digital Successor
The need for evolution led us to find ways to get clearer picture quality and crisp colours on our screens at home and workspace. That’s where audio and video quality was prioritised in the 2000s when HDMI was introduced. And it led to high-definition resolutions and performance.
Even if HDMIs were available at that time, it took until after 2015 for HDMI cables to become a globally used and most common connectivity option. And even then, VGAs existed to compete with them.
Even today, you can find Adapters that help you covert output from VGA to HDMI and vice-versa to ensure connectivity with legacy devices.
DisplayPort: Bridging the Gap
With time, we noticed the introduction of DisplayPort by VESA (Video Electronics Standards Association). Interestingly, it was introduced four years after HDMI, in 2006. Yet, it took a long time for DP to become common ground. It was working to offer the best of both worlds, the high-resolution support and audio performance of both VGA and DVI (Digital Visual Interface) Devices.
Unfortunately, Display Ports are still not as widely used as HDMIs, but they are being recognised for their contributions to the gaming and graphics industry. So, we can expect them to grow in use more.
The Trinity Of Digital Connectivity
VGA was the father of modern-age connectivity, and HDMI cables are still undergoing improvements to offer 4K, 8K and even 10K Ultra HD resolutions. DPI is working on performance, lossless, and low latency outputs for higher refresh rates. These three have worked continually to bring us the display and entertainment world today as we know it. From projectors to theatres and even TV screens, you will find these ports available on most screens.
