Analog Vs Digital (Computer Monitor)

When the video signal information is sent from the computer CPU to the computer video card it is sent in digital. Because CRT monitors were analog based devices, the CRT monitors needed something to convert the video signal to analog so it could process the information. It became the job of the video card inside the computer to take the digital information being sent from the computer and turn the digital information coming into analog. Once the video card converts the digital information into analog it then sends the video signal to the monitor.
LCD displays on the other hand are digital devices and are capable of operating using video information in digital. In order to be compatible with todays video cards that send out analog signalling, LCD displays have circuitry built into them that takes the analog signal coming in from the video card and converts the signal to digital. So what we have is a signal that originates at the CPU as digital then is converted to analog by the video card inside the computer, sent through the video card as analog, and then converted back to digital by a controller card inside the LCD.
Enter DVI (digital visualization interface)- DVI is the standard for processing the video signal all the way from the CPU to the LCD in ts original digital format without converting it to analog and back to digital. The result is a much simpler and cleaner way to process the information. The video signal was, and still is in most cases, sent to the monitor as an analog signal where the CRT monitor would take that signal and process it.
