Which of the following is true of LED monitors?

  1. They use LED backlit technology

  2. They have higher power consumption than LCD monitors

  3. They exhibit longer response times than traditional monitors

  4. They are typically heavier than CRT monitors

The correct answer is: They use LED backlit technology

LED monitors indeed utilize LED backlighting technology, which is responsible for illuminating the display. This allows for improved brightness and energy efficiency compared to older technologies. Additionally, LED backlights can provide better contrast ratios and color accuracy, enhancing the overall viewing experience. The other choices present misconceptions about LED monitors. Higher power consumption than LCD monitors is inaccurate, as LED-backlit displays are designed to be more energy-efficient than traditional LCDs. In terms of response times, LED monitors generally have quicker response times compared to older technologies, so they do not exhibit longer response times. Lastly, LED monitors are typically lighter than CRT monitors due to the differences in technology; CRT monitors are bulky and heavy because of the cathode ray tubes used in their construction.
