The difference between vga and hdmi is: transmission quality, device compatibility.
1, transmission quality
The transmission method of VGA is analog, which means that the signal will be susceptible to interference, as well as some instability, such as distortion, splash screen and so on. This situation may lead to eye fatigue after a long period of time, which is not very friendly for workers.
The transmission method of HDMI, on the other hand, is digital, which means that the signal will be very stable and provide high picture quality. At the same time, HDMI transmits signals faster, typically up to 10.2Gbps, so it supports a wider range of resolutions.
2. Device compatibility
Devices that use VGA ports are basically all laptops, projectors, older TVs, and certain desktop computers that **** have them. Most older devices and older TVs have inputs that only support VGA.
For modern TVs or computers, most support the HDMI interface. This interface is the most popular, and in fact, if you're buying a newer TV or computer, you may only need an HDMI cable to easily connect it to your monitor.
Similarities between VGA and HDMI
The VGA and HDMI interfaces are not only widely used in home TVs, monitors, and computers, but also the application field extends to commercial and industrial areas. For example, popular devices such as large-screen TVs, projectors, and handheld digital multimedia devices use HDMI interfaces, while monitors, displays, medical equipment, and advertising media use VGA interfaces.
Of course, while VGA and HDMI have these ****s in common, their differences do exist. For example, HDMI supports higher resolutions, more colors, and a wider color gamut. This has made HDMI the interface of choice for HDTVs and high-quality multimedia displays. VGA, on the other hand, has been phased out and is more suitable for older devices with lower requirements.
