Since the advent of HDMI, it has become a must-have interface for TVs, projectors and other multimedia devices in the highly competitive consumer electronics market. HDMI interface technology has gained international recognition, and new technology electronic devices have also adopted it. Add to your own port configuration. But for users who are still using VGA port electronics, it doesn't mean they are going to be scrapped.
HDMI to VGA converter is the most widely used interface converter in the market. Its conversion requirements and occasions are also frequent. When we want to present HDMI video signals on VGA-only receiving display devices, HDMI to VGA interface can fully Meet this need.
Principle of HDMI interface to VGA interface conversion
The HDMI interface transmits signals as digital signals, and the VGA interface transmits analog signals and AUDIO audio signals. HDMI to VGA conversion realizes two kinds of signal conversion, and transmits VGA video signal to VGA interface display device to present high-definition picture quality. This interface conversion is frequently used in many teaching and enterprise meetings. However, some people have raised doubts. Since HDMI to VGA is a digital/analog signal conversion principle, will it lose the signal during the conversion process, affecting the video resolution and signal effect?
HDMI to VGA conversion impact on video resolution and signal
1.Resolution
HDMI to VGA conversion process only produces signal conversion, which has no effect on the resolution. The imaging effect can be completely preserved. During the signal conversion process, the point-to-point output is performed, the signal is not compressed, and the auxiliary technology is not processed, so before and after the conversion. The resolution is the same.
2. Signal
HDMI to VGA conversion will not only lose the transmission signal, but also enhance its effect. Why do you say this?
The HDMI digital signal consists of a single point, and the signal is not coherent; the VGA analog signal is composed of continuity curves and is coherent. The conversion of HDMI digital signal to VGA analog signal essentially transforms the inconsistent point signal into a coherent linear signal, which not only does not affect the signal stability, but also enhances the effect. High quality HDMI to VGA converter It can realize high-definition HDMI to high-definition VGA video signal conversion, support 4K HD experience, and imagine the stunning quality.
