How to solve a not working HDMI to VGA adapter

Often times, users with older monitors are faced with a lack of digital connection interfaces on their new video cards. In this case there is only one solution: the use of special adapters and converters. Its correct operation depends directly on the model of the video card, the monitor and the quality of the device itself. If you come across the fact that the purchased equipment is not working, do not get upset, because you can try to fix this problem by several easy methods.

How HDMI to VGA Adapters Work

HDMI and VGA connectors differ not only in shape, but also in operation. VGA is an older connection interface that can only send images to the monitor. HDMI is a more modern solution, which is actively being developed today. This video interface is digital, and is capable of reproducing images in better quality, as well as transmitting audio. The adapter or converter not only allows you to connect to the necessary connector, but also provides a correct transmission of image and sound.

Method 2: Replacing the adapter with an active converter

Normally, when a computer with a new graphics card is connected to an old monitor or television, the power transmitted through the cable is insufficient. Therefore, simple adapters will not output an image. In addition, they do not allow the transmission of sound due to lack of a suitable connection cable.

We recommend buying an active converter in the store and reconnecting it through it. The peculiarity of these equipments is that your system receives additional power through the USB connector, which allows a fast and correct operation. If you also need to transmit the sound, choose the converter with additional connection via minijack.

The above methods are the most effective and usually resolve the problem quickly. However, if none of the methods help, try connecting the adapter to another device, check the cables and motherboard for continuity, or contact your dealer for a replacement.
