HDMI stands for high definition multimedia interface, which is the newer standard in video and audio connections and output. VGA, which stands for video graphics array, is the older standard for video output. It was commonly used with computer monitors from the early 1980s and has long been outdated as a video standard. You should be aware of the problems that may occur when you go from a VGA to an HDMI cable.
VGA to HDMI Cable Connection
An older VGA monitor can operate with an HDMI output through the use of a VGA to HDMI cable. The cable converts the higher standard high definition multimedia interface signal into the lower video graphics array standard. This process is a must if you are running a presentation that still operated with a video graphics array capacity in a high definition multimedia interface world.
Problems Associated with VGA to HDMI Cable
The problems that can be identified when going from the high definition multimedia interface output to the lower video graphics array output include loss of signal, quality of the signal, and no signal. These problems can be the results of a bad connector or port on the video graphics array monitor or a bad signal being sent through the VGA to HDMI cable. When any of these problems occur during the conversion of the high definition multimedia interface signal to the video graphic array signal it can result in frustration and loss of time or productivity as you seek to address the problem.
Simple Solution to VGA to HDMI Cable Connections
The simple solution to this problem, of course, is to upgrade your media to the higher high definition multimedia interface standard. It makes sense since the capabilities of your older video graphics array are limited and can only become worse over time as new standards are developed. That being said, the cost may be a prohibitive factor in being able to fully upgrade your systems. As long as your older video graphics array monitor is capable, your best solution is to determine how to create a patch necessary to operate the VGA monitor and system.
Addressing the signal issues between the high definition multimedia interface to the video graphics array interface starts with identifying the type of problem that you are experiencing. Low, bad quality or no signal may be indicative of something as simple as having the wrong VGA to HDMI interface cable in place, to a faulty HDMI connector.
You can address the incorrect cable by following the installation guide for the component to determine the correct type of interface cable needed to convert the high definition multimedia interface signal for the video graphics array component. You can also check the pin connectors on the VGA monitor and check to make sure that they line up properly. Knowing how to address these problems will help you better connect and operate your distinct output systems.
