The video cable.
A monitor displays images fron the CPU
Through the graphic interface. Video cards are graphic interfaces. The monitor is a passive output device. It displays the video data in the way it is designed to. CRTs display pixel data in a different way than LCD displays do, or LED displays. In any case, the monitor needs a graphic interface to translate the pixel illumination data into a standard video signal.
The CPU is hardware, the "monitor program" is software that runs on the CPU. They are very different things having different and incompatible implementations.
Any output device can do this. A monitor, a printer, or even speakers. Speakers might not "display" information, but their output is a result of processing as you put it.
If the CPU is running, but the monitor has no signal, there could be an issue with the cable that connects the CPU to the monitor. There could also be a problem with the VGA card, or the RAM.
Output device is simply a device which produces an output or result of any processing. For example: monitor is an output device which displays the output of the calculations done by the CPU.
The data bus carries the information from various peripheral devices to the processor, and from the processor to the devices. For example, a running game loads from the hard drive over the SATA or IDE bus, then the CPU processes the data, and sends it to the graphics bus, which displays it on your monitor
the monitor is not the computer, the CPU is. the monitor is basically the screen, but this doesn't always apply to modern desktops, because certain monitors have built in CPUs.
A computer monitor is an output device that displays visual information generated by the computer's graphics card. It consists of a screen that uses pixels to create images and text. The monitor receives signals from the computer through a cable, converting the digital information into visible images on the screen for the user to interact with. The quality of a monitor is determined by factors such as resolution, refresh rate, panel type, and color accuracy.
The "CPU" or Central Processing Unit has little to do with your monitor, which displays images. The CPU is for handing data, or basically running programs. If you have an issue with your monitor not working please make sure it is securely connected to your tower and then try powering it on. Your tower will also need to be plugged into a power source and turned on for this to work. If your screen is frozen or not displaying picture properly please consult a tech specialist to assist you as there are some hardware (physical) issues that are more difficult to support over the internet, especially if new hardware is required.
