In what form do video monitor handles signal?

Video monitor handles typically transmit signals in analog form. Analog signals are continuous waveforms that represent varying quantities. In the context of video displays, an analog signal can encode a range of values, such as brightness and color, creating smooth gradients in image representation.

The use of analog signals in video monitors allows for finer control over the visual output, as the signal conveys continuous values. This smooth representation is crucial for high-quality image display, especially in earlier technologies where digital processing wasn’t prevalent.

While digital signals, which convey discrete values, have become dominating in modern technology, many traditional video connections (like VGA or older cathode ray tube monitors) initially functioned using analog signals. Furthermore, even in digital systems, analog components in the display process, such as in digital-to-analog converters (DACs), can still be involved when rendering images on screens.

It's important to note that digital formats and systems have gained popularity for their efficiency and reliability, particularly in modern computer and flat-screen display technologies, but the foundational understanding of how video signals were historically transmitted remains centered around analog forms.
