John is troubleshooting a display issue on his computer. He is not able to get any display on the screen. After a series of troubleshooting steps, he connects his monitor to another computer. Now he is able to get a display on the computer. Which of the following components need to be replaced?
  1. Motherboard
  2. VGA port
  3. Monitor
  4. Monitor Cable
Explanation
Answer: A - The motherboard needs to be replaced, since all other components are working fine.

Key Takeaway: If the monitor works fine on another computer, it means that the monitor is a good-known one. The issue is with the display element on the PC. The only display element on the PC is the VGA port, which is integrated to the motherboard. A VGA port cannot be replaced individually. The entire motherboard has to be replaced. In general, any port failure on the motherboard demands the replacement of the motherboard.
