The history of the VGA interface can be traced back to 1987. The blue plug is generally used, and it is also the most recognizable interface. The VGA interface has 3 rows of pins, 5 in each row, totaling 15 pins. Our childhood memories---Big head monitors use VGA ports.
The VGA interface transmits analog signals with weak anti-interference ability and supports a maximum resolution of 1080P. The transmission distance of the 3+4/6 VGA cable is 15-30m. The oxygen-free copper VGA cable with thick conductor and good shielding can reach a transmission distance of 30m, and the inferior VGA cable over 15m will cause image quality problems such as smear and blur.
