What type of device is typically replaced by modern flat-screen monitors?

Modern flat-screen monitors have largely replaced CRT monitors. CRT, or Cathode Ray Tube monitors, were the standard display technology for many years, utilizing bulky and heavy glass tubes to display images. These monitors consume more power, occupy more physical space, and have a slower refresh rate compared to modern flat-screen technologies.

Flat-screen monitors, which include LCD and LED technologies, offer significant advantages in terms of size, energy efficiency, clarity, and overall design. These monitors are lighter, take up less space, and provide sharper resolution and better color accuracy.

In context, plasma screens are a type of flat-screen technology, LCD screens are also flat-panel technologies, and LED displays are often a form of LCD that uses LED backlights. However, CRT monitors represent the older technology that has been largely phased out in favor of these more advanced screens.
