VGA memories and future

For almost three decades monitors, computers and multiple televisions have found to have a VGA connector. A Video Graphics Array (VGA) connector is a three-row 15-pin DE-15 connector. The 15-pin VGA connector is found on many video cards, computer monitors, and high definition television sets. VGA connectors and cables carry analog component RGBHV (red, green, blue, horizontal sync, vertical sync) video signals, and VESA Display Data Channel (VESA DDC) data. Original VGA system used 640×480 pixels resolution, but over the years resolutions have inreased to HDTV resolutions and far beyond that. The video signals carried in VGA connector are designed to be matched to 75 ohm load and use coaxial cable.

VGA managed to live longer than many expected. Rumors of the demise of the VGA connector has been going around for a decade now, but VGA has been remarkably resiliant in the face of its impending doom. I asked for example around 5 years ago: VGA is dying? The trend is here, but mush slower than expected at the time.

The trend seems to be that new computers no longer in the near future have VGA connector as it has been replaced more and more with more modern digital interfaces. The transition away from VGA began alongside the introduction of LCD monitors in the mid-2000s. By 2010, the writing was on the wall: VGA would be replaced with DisplayPort or HDMI. Despite this, DE-15 ports abound in the workspace, and until a few years ago, most motherboards provided a D-sub connector, just in case someone wanted to use the integrated graphics.

Now we are in point where VGA is gone from the latest CPUs: Direct VGA support has been removed from Intel’s Skylake chipset (but most proable there is pretty cheap way to add that with some electronics if needed). Some after several years you may no longer buy a new computer with built-in VGA easily.

But VGA is not completely gone. Yup, many good reasons for why VGA is far from gone. VGA is absolutely not dead or going to be for a long time. AV and IT inductries will continue to use VGA for a HUGE number of solutions for a long, long time to come. If you really need VGA signal on VGA connector you still can get DisplayPort or HDMI to VGA adapter. VGA is embedded in most DVI ports. And lots of graphics cards use DVI (very many video cards include VGA on the DVI-I connector). So this year will not bee the year VGA dies.

So now it is a good time to get idea of what VGA was. VGA In Memoriam article gives you introduction to VGA and the downfall of it.
