Often, users with older monitors face a lack of digital connection interfaces on their new video cards. In this circumstance, there is only one solution: the use of special adapters and converters. Its correct operation depends directly on the video card model, the monitor and the quality of the device itself. If you come across the fact that the purchased equipment does not work, do not get mad, because you can try to fix this problem through several easy methods.
How HDMI to VGA Adapters Work
HDMI and VGA connectors differ not only in shape, but also in function. VGA is an older connection interface that can only send images to the monitor. HDMI is a more modern solution, which is currently being actively developed. This video interface is digital and is capable of reproducing images with better quality, as well as transmit 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.

Problem solving: the HDMI to VGA adapter does not work
As it was mentioned already, a connected adapter does not always produce an image on the screen and work properly. In some cases, the monitor, the graphics card or computer model used are simply not compatible with each other or require additional adjustments. The problem of the adapter not working is solved in several easy ways. Let's take a look at them.
Method 1: change screen resolution in Windows
To apply this method, you will need to connect the system unit to a monitor, digitally connected TV or laptop. What happens is that many old monitors do not support working with a higher resolution, so you have to change it manually in the operating system.

Method 2: Replacing the adapter with an active converter
Regularly, when connecting a computer with a new graphics card to an old monitor or television, the power transmitted through the cable is insufficient. Therefore, simple adapters will not output an image. At the same time, they do not allow the transmission of sound due to lack of a suitable connection cable.
We suggest to buy an active converter in the store and reconnect it through it. The peculiarity of these computers is that your system receives additional power through the USB connector, which enables 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 generally solve the problem quickly. Despite this, if none of the methods help, try connecting the adapter to another device, check the continuity of the cables and motherboard, or contact your dealer for a replacement.
