Cable and adapter from VGA to HDMI for a monitor with sound: diy diagram

Distinctive features of the VGA and HDMI interfaces

1987 is considered the time of the creation of the iconic and recognizable connector, called "Video Graphics Adapter" or abbreviated as "VGA". Until 1998, this standard had practically no noticeable competitors.

Outwardly, it is a trapezoidal port with fifteen contact holes. It is only capable of handling analog video signal like older TVs. Due to the limited data transfer capabilities, VGA did not allow for a high-quality image on the monitor. This became especially noticeable when high-resolution screens appeared - the "picture" was notable for blurry and incorrect colors. Also, the quality was determined by the length of the cable - the longer it is, the less decent result the user received.

The DVI interface that replaced VGA showed better results, but it could not reach the top of another hero of our article - HDMI. Outwardly, it looks like a smaller and flatter version of the USB connector. Unlike its "wild ancestors", it works with a digital signal to transmit information. This allows you to broadcast to the monitor a better image of any resolution.

NOTE!

A special advantage of the digital interface is the ability to transfer audio files and play them. Solid savings, isn't it ?!

Types and areas of application of the VGA to HDMI adapter - who is it profitable to buy it

To "make friends" two incompatible ports, engineers have developed special converters - adapters. They have fundamental design differences. There are the following commonly used options:

Modification	Appearance	Peculiarities
Cable		It can be used only when there is a function for recognizing analog information by the image output equipment.
HDMI to VGA Converter Adapter		Most often, this option is used to connect an old monitor to a modern powerful video card, the second name is an active adapter.
Portable model		Has a compact size, connects to the required output depending on the situation (VGA to HDMI or HDMI to VGA).
Converter		Provides the most reliable signal transmission, effectively works with any type of equipment, but has the most cumbersome form.

NOTE!

Beware of scammers and unverified firms selling Type 1 modifications. Often, unscrupulous manufacturers offer, under the guise of a quality product, two headbands of HDMI and VGA cables connected in a primitive way, without taking into account the features of data conversion.

Adapters of this type have a wide range of applications:

1. Connecting an old system unit to a modern monitor or TV, as well as reverse situations.
2. Connecting an old projector to a digital input on a PC or similar technology.
3. Connecting multimedia devices (for example, game consoles) to television equipment and (less often) monitors.

How does the VGA-HDMI monitor cable and adapter work?

A VGA to HDMI monitor adapter is essentially an analog to digital converter. That is, it receives visual and audio signals in an outdated format, processes them and transmits them to the user to the information output device. To perform all the "manipulations" the equipment does not need external power supplies, it receives electricity from the resources of the system unit.
