What is an S port, VGA port

Problem description:My computer is Lenovo imitation infiltration D2030E,The LCD display itself is 17 inches,I have a 54-inch large TV at home,I want to get the *** movie on the Internet to watch on the TV (TV with S port).But there is no S port on this computer,Only VGA port,Later, I saw on the Internet that there is a VGA to S port connection to Bibi ridge line,But I don't know if it can be used,Because I saw that the graphics card that says VGA should support (TV) The output function of the TV,I checked this LenovoD2030E graphics card is via technologies inc |via S3G Unichrome Pro IGP (this graphics card) I don't know which master said it,This graphics card supports TV output or not。 I really want to connect the *** movie to my TV set through the VGA to S port to watch it for several lifetimes.,If you can't ask what's the trick?,Thank you!

As far as I know, the VGA to S terminal needs a converter, and such a converter** may be much higher than the adapter cable, you can go to the electronics market to see, but the adapter cable is not recommended, because there is no way to guarantee the quality.

The best way is to connect directly to the VGA interface,The strange thing is that mainstream large-screen TVs should have VGA interface

The VGA is the interface that we often use to connect the computer to the display cable, which is blue.

Now there is also an HDMI port, which is white.

Answer: VGA interface is a special interface for the computer to output data using the VGA standard. The VGA connector has a total of 15 pins, divided into 3 rows of 5 holes, and is the most widely used type of interface on graphics cards, and most graphics cards have this type of interface. It transmits red, green, and blue analog signals as well as synchronous signals (horizontal and vertical).

The VGA interface is the interface that outputs analog signals on the graphics card, and the VGA (Video Graphics Array) interface is also called the D-Sub interface. Although the LCD can directly receive digital signals, many low-end products use the VGA interface in order to match the VGA interface graphics card. The VGA connector is a D-type connector with a total of 15 empty pins on it, divided into three rows of five each.

The VGA interface is the most widely used interface type on graphics cards, and most graphics cards have this interface.

At present, most computers are connected with external display devices through analog VGA interfaces, and the display image information generated digitally inside the computer is transformed into R, G, B three primary color signals and line, field synchronization signals by the digital analog converter in the graphics card, and the signal is transmitted to the display equipment by cable. In the case of analog display devices, such as analog CRT displays, the signal is sent directly to the corresponding processing circuit, which drives the control CRT to generate the image. For digital display devices such as LCD and DLP, the display equipment needs to be equipped with a corresponding AD (analog-digital) converter to convert the analog signal into a digital signal.

After the D a and A D 2 conversions, it inevitably caused some loss of image details. The VGA interface is understandable for CRT displays, but when it is used to connect a display device such as a liquid crystal, the image loss during the conversion process will cause the display effect to decrease slightly.

You need a VGA cable, and the interfaces on both sides should be the same, because the VGA interface of the TV and the VGA interface of the graphics card are the same.
