An analog monitor is a type of computer monitor that accepts continuously varying or analog signals from the video adapter for an infinite range of different colors. It is a cathode ray tube (CRT) display, like a traditional television. Although analog monitors have been dominant for decades, the digital revolution in the 1990s brought flat-panel liquid crystal displays (LCDs).
Characteristics and Advantages of an Analog Monitor
Most CRT monitors are analog monitors, while all flat panel monitors are digital. An analog monitor can accept only a narrow range of screen resolutions, such as VGA only or VGA and Super VGA. On the other hand, it can accept a wide range of signals, including TV.
When compared to digital monitors, the main draw of analog monitors is that they are cheaper. They also do not require as much bandwidth as digital monitors, which is important when bandwidth is limited, such as in older computer models.
If you’re working with an older computer that only has an analog video output or you’re on a tight budget, an analog monitor can be a good choice. However, improvements in LCD technology and falling prices have made digital monitors a better choice for most users. By 2003, sales of digital monitors had overtaken CRTs.
Frequently Asked Questions (FAQ)
What is the difference between an analog monitor and a digital monitor?
An analog monitor is a type of computer monitor that accepts continuously varying or analog signals from the video adapter for an infinite range of different colors. Most CRT monitors are analog monitors. On the other hand, a digital monitor is a type of computer monitor that displays digital signals from the video adapter.
Can I still use an analog monitor with a modern computer?
It depends on the video output of your computer. Most new video cards come with digital interfaces such as DVI, HDMI, and DisplayPort. However, some video cards still have analog outputs for compatibility with older displays. You may need an adapter to connect the analog monitor to a digital interface.
Final Thoughts
An analog monitor is a type of computer monitor that has been largely surpassed by digital monitors. While it has some advantages such as being cheaper and requiring less bandwidth, improvements in LCD technology and falling prices mean that digital monitors offer a better picture quality and features.
