When dealing with dead pixels or artifacts and monitors, what is the best way to resolve the issue?
  1. Use a large magnetic to realign the fields.
  2. Degauss the monitor.
  3. Replace the monitor.
  4. Reinstall the monitor’s drivers.
Explanation
Answer: C - When dealing with dead pixels or artifacts and monitors, it is best to replace the monitor.

Key Takeaway: After time, pixels can stop shooting on a monitor, making for dead pixels. Likewise, if the same image has been sitting on a monitor for a long time, this can cause burn-in and leave what are called “artifacts.” To avoid this, use a screensaver with older monitors that are susceptible. In both cases, the monitor would be far more expensive to repair than replace, so replace is the way to go.
