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\
DVI cábla
Tarchuireann Comhéadan Amharc Digiteach, an cábla físeán digiteach is déanaí, gach comhartha digiteach le teicneolaíocht neamh-chomhbhrúite, agus is é 8Gbps an luas tarchurtha uasta. Faoi láthair, tá luas tarchurtha suas le 8Gbps ag an gcábla comhartha físe digiteach arna thacú ag an gcuid is mó de na monaróirí, agus tá 24 móide 1 (DVI-D), 24 móide 5 (DVI-I) ag a chomhéadan. cineál, DVI-Tacaíonn I le tarchur comhuaineach comharthaí digiteacha (DVI-D) agus analógach (comhartha VGA). Go ginearálta, is comhéadain DVI-I I iad cártaí grafaicí HTPC, agus tá comhéadan DVI-D ag monatóirí agus teilgeoirí LCD. Cé go bhfuil comhéadan DVI{12}}I comhoiriúnach leis an gcomhéadan DVI-D, ní féidir an breiseán DVI-I a chur isteach sa chomhéadan DVI-D. Cén fáth? Tá ceithre bhioráin eile ann. Ach tá bealach fós againn, ag baint úsáide as tiontaire DVI-I go DVI-D.
