How do graphics cards work?
In: Technology
* GFX cards take date from the computer about what should be on the screen and use it to generate the proper electrical signals to send to the display device to create the images you see.
* That electrical signal specifies what color literally every pixel of the display device should be.
* The computer will say things like, “Put a rectangle there, put a triangle here, put a circle way over there”.
* The GFX card translates that into a signal that says “make the next dot dark green, make the next dot red, make the next dot light blue”.
* For the nerds: this was very dumbed down to make it ELI5.
