What should you pay attention to in computer monitor connectors?
The increased demand for computer monitors has driven progress in their design for even higher image resolution, as well as in the construction of dedicated connectors. The type of connector corresponds to, among others: for the quality of the transmitted signal.
When choosing an LCD monitor , more and more users notice a large number of different sockets on their housings and wonder how to properly connect the monitor to external devices. Among the LCD monitor connectors designed to work with PC computers, there are two basic groups, i.e. analog connectors , known from CRT monitors, and digital connectors , which are constantly being developed.
In the case of image transmission via analog connectors, the computer undergoes an extensive process of converting the digital signal into an analog signal sent to the monitor and converted by its components into a digital signal converted into an image. Such multi-step conversion may result in a reduction in image quality, but it also depends on the quality of the transducers. In the case of purely digital image transmission, we do not have to worry about quality loss.
Connector type D SUB
LCD monitor connectors can also be divided according to the differences between the connected devices - these include input connectors for PCs and input connectors for AV devices. We encourage you to familiarize yourself with the entire range of connectors category, which includes, among others: BLS , ARK connectors, DC sockets and plugs , FFC / FPC ZIF connectors and many others.
Additional information about D SUB connectors
Computer input connectors mainly include: D-SUB sockets for transmitting analog signals; DVI-D for transmitting digital signals; DVI-I for transmitting analog and digital signals; HDMI for digital image and sound transmission and USB.
D-SUB and DVI - standard computer connectors and parallel port connector
In addition to image transmission, D-SUB connectors are also used in serial, parallel (parallel port connector), SCSI and other ports with a number of pins adapted to the needs of the application. D-SUB as a connector for analog image transmission, is also known as VGA. Such a connector has 15 pins arranged - five pins in three rows, but there are also designs in which unused pins are not factory-installed.
D-SUB connectors are still widely used and fit most monitors and PCs (regardless of housing type) equipped with a D SUB input. DVI connectors, on the other hand, come in three standard forms: DVI-D for digital signal transmission; DVI-A for analog signal transmission and DVI-I which also serves as DVI-D and DVI-A connectors.
