How do video adapters create images seen on a computer monitor?

Video adapters, also known as graphics cards, convert digital data from the computer's CPU into visual signals that can be displayed on a monitor. They process graphical data using a dedicated GPU (Graphics Processing Unit) to render images, animations, and videos. The adapter then sends these processed signals through various output connections (like HDMI or DisplayPort) to the monitor, which translates them into the images and videos we see. This entire process involves complex calculations and manipulations of pixels to create the final visual output.
