Difference Between HDMI And VGA
In this article, we are going to tell you the difference between VGA and HDMI cables. You can also read our article on different types of CCTV cables.
What is HDMI?
HDMI stands for High Definition Multimedia Interface. Thanks to this, audio and video are transmitted at the same time via cable. It combines audio and video as a digital interface on the DTV player, HDTV, set-top box, & other AV devices.
It is the core technology for high bandwidth digital content and the basic security of the digital display interface.
Do You Know The Difference Between:
What is VGA?
VGA stands for Video Graphics Array. It was created by IBM in 1987. It was introduced by IBM on ps / 2 line systems. At the time, it gave 640 x 480 resolution and a 60 Hz upgrade rate.
It uses an analog signal instead of a digital signal. It is a port that connects the display and processor using a cable, this cable is called a VGA cable.
Features HDMI Cable
- High speed data transfer
- Replace images with quality
- The ability to compress data files concisely
- Use a single port and reduce the number of transmission cables
- Ability to convert CCTV video and audio files simultaneously
Types Of HDMI Connectors
The main advantage of HDMI is the ability to carry audio and video. However, HDMI 1.4 is limited to 4K resolution at 30 frames per second, and while HDMI 2.0 supports 4K to 60 frames per second, the new version is limited.
The length of the HDMI cable and the size (thickness) of the wire inside are two things to consider. Cable length is a bit important. In general, all HDMI cables are identical.
These discrepancies are indicated when the height is above 50 feet. For example, your DVR is located in an area of your house or building and you want to install it on a screen 50 feet above the DVR.
Sure, you can run a cable for a long time, but you may lose some credibility. The next thing to consider is measuring the wire in the HDMI cable. On most cables, you will notice that the AWG number is printed along the length of the cable. A
WG stands for American Wire Gauge, a standard system for measuring the diameter or thickness of a conductive wire. There is a lot of debate about the quality of HDMI cables and obviously, there are many price differences.
Which HDMI cable is right for your CCTV system?
The answer is really simple, the cable that shows the movie; This means that if the cheap cable you purchased at the gas station allows you to shoot the DVR on a full HD screen, another cable with a higher price will not provide the best picture.
Types of VGA Connectors
There is only one type of VGA patch and it is mostly blue, with 15 needles in the male form and 15 needles in the female form. The pins or holes have three rows, and each pin or hole performs different functions.
These functions include RGB information, power, vertical or horizontal synchronization, and electric field. You will usually rotate two screws to connect the cable to the monitor.
Most computers and televisions still have these ports. The main advantage of today’s VGA connection is that older technologies such as projectors are always compatible with it. It also works well against input delays.
Which is better, VGA or HDMI?
For some reason, when it comes to VGA and HDMI, HDMI is much better than VGA. HDMI is capable of transmitting more data, but it also transmits audio. VGA, on the other hand, is capable of sending only low-resolution images.
What is the Difference Between HDMI And VGA?
1. HDMI has digital signals because it is the digital video standard. It has an analog signal as it is an analog video standard.
2. This is still very new. This is very primitive.
3. It can accept multiple signals with video. It can only take video signals.
4. It’s better than VGA for video games. It’s not as good as HDMI for video games.
5. Audio signals do not require a separate cable. Audio signals require a separate cable.
6. It offers higher frame rates and higher resolution than VGA. Provides lower resolution than HDMI.
7. HDMI to VGA converters (passive cables) are less expensive. VGA to HDMI adapters are more expensive than passive cables.
8. HDMI was developed by seven founders: Hitachi, Panasonic, Philips, Silicon Image, Sony, Thomson, RCA, and Toshiba. It was developed by IBM.
