How to convert HDMI to VGA or VGA to HDMI.

VGA to HDMI connectorToday's video technology is moving away from analog (VGA) for a digital connection format (HDMI, DVI, DisplayPort). However, there are still situations where you may need to change the display technologies, usually due to differing ports on a computer and display. Video signals may be adapted in either direction (HDMI to VGA or VGA to HDMI), but there are certain limitations and expense differences.

VGA to HDMI

In some situations, it may be necessary to send a VGA signal from a computer to an HDMI connection on a newer display, TV, or projector. Using a VGA to HDMI Scaler/Converter, like the one shown in the picture above, allows you to connect your computer to any device requiring an HDMI connection.

Note: As can be seen in the picture above, this converter also includes a USB cable that takes the audio from your computer and includes it with the video signal. Some converters may have an audio cable, as well as a USB cable, for power.

Tip: If your computer only has a VGA connection and you have a desktop computer, you may also consider upgrading the video card in the computer.

HDMI to VGA

An HDMI to VGA converter may be a cheaper cable that can connect an HDMI signal from a computer to a VGA connection on an older display. Because VGA is an older technology, this option should be avoided unless there is no other alternative.

Note: An HDMI cable can send an audio and video signal over the same cable. However, a VGA cable can only accept a video signal. If you want both audio and video, you need to purchase a converter that has a VGA cable, as well as an audio cable or USB with audio capability.

Signal quality considerations

Please note that moving between these two technologies may cause you to experience a loss of video quality. VGA, even in its highest resolution from SVGA, is only capable of an 800 x 600-pixel resolution. Therefore, if your computer is sending out a higher resolution HDMI signal, it will be restricted by the lower resolution of VGA. Additionally, analog VGA signals are susceptible to a loss of quality based on what their cables are made of and how well they are put together.
