Vga interface knowledge

Vga interface specifications are the same, are 15-pin,

The only difference between the main core in the above, there are 


three, respectively, 3 +4 .3 +6 .3 +9.

What does it mean, that is, the number of cores is different.

Core and more, the transmission of data will be more stable, the longer 


the distance, the higher the cost.

3 + 9 is better than 3 + 4 with 3 + 6 is able to automatically detect 


the resolution with the resolution device.

So why there are 8 yuan vga line, there are 30 yuan vga line

Vga interface knowledge

The information processed by the graphics card will eventually be 


output to the display, the graphics output interface is the bridge 


between the computer and the display, which is responsible for the 


output of the corresponding image to the monitor signal. CRT display 


because of design and manufacturing reasons, can only accept analog 


signal input, which requires the graphics card can output analog 


signals. VGA interface is the graphics card output analog signal 


interface, VGA (Video Graphics Array) interface, also known as D-Sub 


interface. Although the liquid crystal display can directly receive 


digital signals, but many low-end products in order to match the VGA 


interface graphics card, which uses VGA interface.


Vga line connection diagram

VGA cable connection is very simple, one access to the computer's VGA 


output port, the other end access to the monitor VGA input interface 


can be, and finally for everyone with VGA interface internal pin
