CHAPTER 3: VGA to HDMI ConverterĪ lot of technical things need to happen simultaneously to change a VGA signal into HDMI. These things usually involve connecting these two interfaces. In case your TV monitor needs an RCA for its audio, i.e., only the red and white, you have to get an affordable 3.5mm audio port to the RCA device converter. However, a regular person would recognize them more easily as the colored ports in a TV: red, yellow, and white.Ī video is transmitted using the yellow port, whereas the white and red RCA ports are designated for audio signal transmission. These audio connectors can also be called component audio connectors.

Sometimes there are audio inputs seen in devices known as RCA connectors. In these situations, you’re in luck since you’ll only require the 3.5mm audio cable without any other conversion technology. Occasionally, your TV set can also come with an audio port and an HDMI port just for the exact purpose of connecting your computer that uses a non-HDMI interface (such as VGA or DVI).

It resembles a regular headphone jack, and in laptops and computers is the main headphone port. Usually, a PC or TV set comes with the basic 3.5mm audio port. To utilize audio support in such cases, you’ll have to get a separate cable that acts as an audio channel. It is also accurate for situations where VGA is converted to HDMI, even though HDMI does provide audio. I think it’s safe to say that you now know that VGA interfaces cannot transmit an audio signal. PCs that use the VGA interface have to work with lower video resolution due to limitations with the video card.Īs for previous displays using the VGA interface, you usually have a problem with screen resolution. Generally, devices with a VGA interface provide reduced video resolution in comparison to newer HDMI devices. That being said, it’s great to know that these adapters are compact and very cheap, most of them averaging around 20$. The second one is that VGA only provides you with video transmission, whereas HDMI involves audio and video transmission.ĭue to these differences, you will require not only a cable when connecting an HDMI device to a VGA device, but for the conversion to properly occur, you will need an adapter as well. The first difference is the type of interface, with VGA being analog and HDMI being digital.

There are two main definitive differences between HDMI and VGA sources. The now more common interface works to transmit both audio and video signals digitally using an HDMI-compatible source. Meanwhile, HDMI stands for “High-Definition Multimedia Interface.” In previous years, VGA became the fundamental lowest denominator for every computer graphics system. Before getting into any conversion methods, you’ll first need to understand what VGA and HDMI mean.
