PC Main Unit ⇒ This Product ⇒ VGA Cable ⇒ Display This is a conversion cable for connecting a D-sub 15-pin 2-row analog RGB output from a PC to a third-party display with a mini D-sub 15-pin 3-row input (commonly referred to as a VGA terminal, analog RGB terminal, or shrink D-sub 15 terminal). (It has a simple structure that only converts the pin assignments.) It is used by connecting it to the VGA cable coming from the display, allowing you to use one display with multiple PC models. (The blue cable often included with displays. D-sub 15 3-row) Compatible Models: Sharp Fujitsu NEC #PC-9801 #PC-8801 Compatible Displays: Displays with a mini D-sub 15-pin 3-row input terminal (commonly called a VGA terminal) that support the screen modes of the PC models being used. (Horizontal sync frequencies of 31/24/15kHz, etc.) (There seems to be a lot of information online, such as displays that can display an image but require adjustments on the display side.) Please find a suitable combination of PC main unit and display that is compatible and has good synergy. Details: The RGB and sync frequency GND grounds are separated into different systems. (Of the 9 pins, RGB GNDx3 and Sync GNDx1 are connected independently. A total of 4 pins are used for GND. The D-sub 15 2-row Sync GND is connected to the common ground for the above 4 models, making it a more versatile specification.)
