VGA cable: It is also an analog signal video cable. It is most commonly used in computers. Its signal is different from the color difference cable. However, as the amount of video data increases, for example, 1920X1080P video signals will be transmitted in the future, then the redundancy of the color difference cable. It will be larger. After the resolution exceeds 1600X1200, the quality of the VGA cable will be slightly inferior, and the length will cause snowflakes. Why do home theaters mention VGA cables? That's because HTPCs have entered home theaters, and all projectors have VGA ports.
The information processed by the graphics card is ultimately output to the monitor. The output interface of the graphics card is the bridge between the computer and the monitor, which is responsible for outputting the corresponding image signal to the monitor. CRT monitors can only accept analog signal input due to design and manufacturing reasons, which requires the graphics card to be able to input analog signals. The VGA interface is the interface that outputs analog signals on the graphics card. The VGA (Video Graphics Array) interface is also called the D-Sub interface. Although LCD monitors can directly receive digital signals, many low-end products use VGA interfaces in order to match with VGA interface graphics cards. The VGA interface is a D-type interface with a total of 15 pins on it, divided into three rows, five in each row. VGA interface is the most widely used interface type on graphics cards, and most graphics cards have this interface. The fracture has one male and one female\two males\two females\
kabel DVI
Antara Muka Visual Digital, kabel video digital terkini, menghantar semua isyarat digital dengan teknologi tidak dimampatkan, dan kelajuan penghantaran maksimum ialah 8Gbps. Pada masa ini, kabel isyarat video digital yang disokong oleh kebanyakan pengeluar mempunyai kelajuan penghantaran sehingga 8Gbps dan antara mukanya mempunyai 24 tambah 1 (DVI-D), 24 tambah 5 (DVI-I) jenis, DVI-Saya menyokong penghantaran serentak isyarat digital (DVI-D) dan analog (isyarat VGA). Secara umumnya, kad grafik HTPC secara amnya ialah antara muka DVI-I, manakala monitor LCD dan projektor mempunyai antara muka DVI-D. Walaupun antara muka DVI-I serasi dengan antara muka DVI-D, palam DVI-I tidak boleh dimasukkan ke dalam antara muka DVI-D. kenapa? Ada empat pin lagi. Tetapi kami masih mempunyai cara, menggunakan penukar DVI-I ke DVI-D.
