As you might know, high definition resolution, via the High Definition Multimedia Interface (HDMI) is becoming the norm in displays for screens everywhere. While a lot of people still use their composite or composed cables, these just can’t compete with the quality and sheer power of the HDMI interface.
There are two reasons why HDMI gives such a better video quality.
The first reason is that both the source device and the receiver handle digital data, which travels much faster compared with analog data of standard TVs and old source devices.
The second reason is that HDMI features a much greater bandwidth, so the digital information not only travels fast but also in big quantities.
The result is that the receiver gets much more information in less time, which translates into a higher video resolution.
Nevertheless, you may have some computers that are still useful but don’t support the HDMI interface. Instead, they support VGA, which is the abbreviation of Video Graphics Array.
If this is your case, you can use a VGA to HDMI converter in order to connect that old computer to a high definition screen.
A VGA to HDMI converter isn’t cheap. It may cost from 100 to 250 dollars, depending on the name of the manufacturer, as well as the specific functions of the VGA to HDMI converter.
Despite the price, a VGA to HDMI converter is still more convenient than getting rid of a computer. And as you know, not every computer has to be a state of the art piece of electronics. If you have an old computer that you only use to write documents and maybe check your e-mail, then there’s no need to get rid of it. A lot of people have a personal computer and a laptop, and they only need to keep one of them upgraded.
However, if for some reason the monitor of that computer is broken, getting a VGA to HDMI converter is cheaper and easier to get than a new monitor. So, it might be a good investment.
When buying a VGA to HDMI converter, it’s convenient to study the options they give you. Obviously, the more options a VGA to HDMI converter has, the more expensive it will be. For example, if you plan to use your computer for applications that don’t use sound, then there’s no point in paying for a VGA to HDMI converter that supports audio. On the other hand, if later on, you want to play a CD or a DVD on that computer, you should definitely get a VGA to HDMI converter that supports audio.
Also, if you have a profession that requires you to give presentations often, then it’s a good idea to get a VGA to HDMI converter and carry it with your laptop. That way, if there is an HDMI TV available, you can use it to give your presentation.
