While considered a lesser standard, the 4:3 image ratio of old school VGA monitors is by no means obsolete. Most computers still use VGA to HDMI cables to transfer digital pictures from their video boards to the computer screen, even if HD quality is supported by both components. Moreover, VGA cables are far more widespread and accessible especially when considering lower resolution, cheaper devices.
VGA cables have been used for decades. If you walk into a computer shop or museum and see an old Pentium II computer that now looks like it came from the dark ages, you’ll notice that it still uses the same kind of VGA cable that most monitors use today.
The most common use of a VGA cable is to connect a computer screen to the video board or motherboard of a computer. But there are other uses as well. The cables used to connect electronic projectors are also typically VGA cables, and some DVD players also allow for VGA connectivity.
Moreover, in many cases you can even use VGA cables to connect one PC to another – including the task of interfacing a laptop with a desktop computer. If your laptop has a better quality screen and your desktop has better processing power, you can connect them so that you’ll see the animations and games on the laptop’s screen while playing them on your desktop.
