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\
Cable DVI
Digital Visual Interface, l-aħħar kejbil tal-vidjo diġitali, jittrasmetti s-sinjali diġitali kollha b'teknoloġija mhux kompressata, u l-veloċità massima tat-trasmissjoni hija 8Gbps. Fil-preżent, il-kejbil tas-sinjal tal-vidjo diġitali appoġġjat mill-biċċa l-kbira tal-manifatturi għandu veloċità ta 'trażmissjoni sa 8Gbps, u l-interface tiegħu għandu 24 plus 1 (DVI-D), 24 plus 5 (DVI-I) tip, DVI-I jappoġġja t-trażmissjoni simultanja ta' sinjali diġitali (DVI-D) u analogi (sinjal VGA). B'mod ġenerali, il-karti tal-grafika HTPC huma ġeneralment interfaces DVI-I, filwaqt li l-moniters LCD u l-proġekters għandhom interface DVI-D. Għalkemm l-interface DVI-I hija kompatibbli mal-interface DVI-D, il-plagg DVI{-I ma jistax jiddaħħal fl-interface DVI-D. Għaliex? Hemm erba 'labar oħra. Iżda għad għandna mod, billi nużaw konvertitur DVI-I għal DVI-D.
