A VGA to HDMI converter is a device that converts one form of signal to another. Some people think that a VGA to HDMI cable is enough to get the job done which is impossible. An analog signal cannot be changed to digital in an instant without a converter. A VGA output is commonly produced by a laptop or computer that uses a VGA video card, from there the converter converts the signal to HDMI (digital signal), the result will then work with an HDTV or any HMDI compatible devices. VGA only supports video while HDMI supports both audio and video.
VGA to HDMI converters can produce 720p and 1080p resolutions. You can't really tell the difference between the two if you don't care about the resolution as long as the display is clear. A 720p scale converter is actually good enough; it can produce a display that's full colored, clear and high quality. The difference between the two is not that obvious compared to the difference between 420p and 720p. If you focus in comparing the results between the two high definition resolutions, only then will you be able to tell the difference. Of course 1080p provides more details since it has twice the number of pixels. A 1080p frame has about 2 million pixels, and 720p only has 1 million pixels. When it comes to pricing, obviously, 1080p scale converters are more expensive than 720p. Many people prefer an HDMI output because it provides a high quality display image. It is the resolution that makes this kind of converter superior over other PC to TV converters available.
Finding a VGA to HDMI adapter is not a very difficult task as long as you have enough information regarding the whereabouts of the device. This device is readily available in computer stores and online. Aside from the VGA to HDMI converter itself, you will also need an HDMI cable of enough length to complete the job. With this device, your VGA to HDMI connection now have a solution.
On the other hand if you want to get a converter, you have another option. For a PC, you can replace the VGA video card to DVI. In this case, you will no longer need a converter since the signal that is produced by DVI video card is almost identical with HDMI, and it only requires an adapter cable to go between the two because they are both digital.
