Before one can truly appreciate how to convert a video graphics array (VGA) to a High-Definition Multimedia Interface (HDMI), one has to first understand what they are. Why make the change if one doesn't even understand what the two are.
What is VGA?
VGA started as a chip in the IBM computers. It was meant as a way of providing graphics. However, as time has gone on, it has gained a second name, replacing array with adapter. Therefore, adapters like the 15-pin adapter is a VGA adapter. It pushes VGA through it and puts that on the screen.
VGA is backwards compatible with EGA and CGA adapters. Therefore, it can put the sixteen colors that EGA can use and the sixteen colors that CGA can use and then amplify them and put up a total of 256 different colors. This creates a clearer and more effective image.
What is HDMI?
Unlike VGA which deals in analog, HDMI deals in digital. Therefore, it is able to project a much clearer image. With the arrival of blu-ray and other high definition applications, it has become necessary for a stronger and higher resolution; therefore, HDMI was created. It has only been out since about 2003, but already, it has sold tens of millions of units and is quickly becoming a favorite.
Converting VGA to HDMI
To convert VGA to HDMI is very difficult unless there is an converter purchased. Deciding which to buy can, often times, be a bit difficult. According to reviews, Scaler makes an inexpensive, but very durable converter. Simply connect the two wires to the converter and the feed that comes in will be VGA; however, after it goes through the converter, it comes out as HDMI.
The downfall for these types of converters is that they come out with a 720 resolution. To make it 1080p, one has to get a scaling converter. This triples the cost, typically, of the converter. However, what this does is convert the VGA to HDMI, but also converts the 720 resolution to 1080p. However, if the television is less than 37 inches, that resolution can't be noticed. Therefore, going with the scaled converter really isn't necessary unless the individual plans on getting a larger television or already has it.
In the end, all that is really needed is the converter and the correct cables. The VGA comes into the converter and out comes HDMI. The quality of the picture is significantly better and therefore, the experience is significantly better.
