One, VGA interface
How important is the VGA interface Presumably, many friends have a deep understanding, this sprouting trapezoidal interface for the transmission of analog video signals has a full 20 years of history. In the past, when the computer needed to connect with the display device is usually through the VGA interface, this interface is also commonly used in projectors.
Second, HDMI interface
As for HDMI, the English name is "High Definition Multimedia," and Chinese means high-definition multimedia interfaces. It is a dedicated digital interface suitable for image transmission. It can simultaneously transmit audio and video signals. The maximum data transmission speed is 5Gbps. HDMI can not only meet the 1080P resolution, but also support digital audio formats such as DVD Audio, support for eight-channel 96kHz or stereo 192kHz digital audio transmission. Supports EDID, DDC2B, so HDMI-equipped devices have "plug-and-play" features, and the signal source and display device will automatically "negotiate" and automatically select the most appropriate video/audio format. Now smart TV, TV box HDMI interface is used as a common interface, can be directly connected to smart TVs and laptops. Display notebook video or audio, documents to the big screen.
For notebooks with VGA and HDMI interfaces, you can easily add other display devices. For example, when you take your notebook home, you can connect your home HDTV to watch movies and TV shows. You can access a VGA port at work. Projector, play PPT or video for presentation. Especially for practical users, the presentation function of the notebook is extremely important, and it is very convenient for both home and business use.
Comments: Now with the increase in various types of interfaces, functionality is enhanced, and the sharing of notebook content to large screens is very convenient. The use of large screens has also been greatly improved in the home. Whether it is a smart TV or a smart projector, it can be easily connected to a laptop. So now choosing smart devices, the choice of interfaces has become particularly important, do not ignore the important part of the interface, otherwise you missed the world have not found.

Digital Home Appliances Circuit Board
At the end of the 1940s, the first semiconductor triode was born in the world. With its characteristics of small size, light weight, power saving, and long life, it was quickly used by various countries and replaced electronic tubes in a large range. In the late 1950s, the first integrated circuit appeared in the world. It integrated many electronic components such as transistors on a silicon chip, making electronic products smaller. Integrated circuits have rapidly developed from small-scale integrated circuits to large-scale integrated circuits and ultra-large-scale integrated circuits, thereby enabling electronic products to develop in the direction of high efficiency, low consumption, high accuracy, high stability, and intelligence.
