Why Your VGA to HDMI Adapter is Not Working
How to Troubleshoot VGA to HDMI Adapter Not Working Issue
First, let us get the fact out of the way that VGA signals are analog while HDMI signals are digital. Thus, converting VGA signal to HDMI needs the use of anactive converterchip. These chips register the analog VGA signal sent though your PC and converts them to digital HDMI signal so that monitor can correctly interpret display signals.
Furthermore, VGA interfaces don’t support transport of audio signals while HDMI interface does. Some converter chips even allow you to connect your PC’s audio signal which then gets seamlessly integrated into the outgoing HDMI signal.
However, since the processing is happening outside the PC, the converter needs to be powered separately. Thus, they are referred to as “active” converters.
If your HDMI to VGA cable does not have an active converter,there wont be any HDMI signals.
Users have reported cases where they were conned into buying a cable with VGA adapter at one end and HDMI on the other end without any active converter. If you too own such a cable, then you will need to return it.
Check the Connections, Try Restarting Your Computer
You willnot get a signalif the cable is not securely connected at either end. ensure this is not the case.
Also, verify if your display’s power cable has come loose.
Sometimes a bug might prevent your adapter from being detected properly, in which case restarting your computer can remedy this. Thus, please try restarting your computer and see if this fixes the issue.
