- A
The monitor's color temperature is set incorrectly.
Why wrong: Color temperature settings would affect the entire monitor uniformly, but a pink tint from a cable issue is due to a missing color channel, not a setting.
- B
The graphics card driver is corrupted.
Why wrong: A corrupted driver would likely affect both monitors or cause other artifacts, not a single color tint on one display.
- C
The video cable is not fully seated or has a bent pin.
A loose connection or bent pin can cause a missing color channel, resulting in a pink tint (missing green or blue). Reseating or replacing the cable fixes it.
- D
The monitor's backlight is failing.
Why wrong: A failing backlight would cause dimming or uneven brightness, not a specific color tint across the entire screen.
Quick Answer
The answer is a loose or damaged video cable, specifically one that is not fully seated or has a bent pin. This is the most likely cause because a pink tint on a monitor indicates a missing blue color channel—when the blue signal is lost, the remaining red and green channels combine to create a pink hue. On the CompTIA A+ Core 1 220-1201 exam, this scenario tests your ability to troubleshoot display issues in a dual-monitor setup, where one faulty cable can cause color distortion while the other monitor works perfectly. A common trap is to blame the graphics card or monitor settings, but the key is that only one display is affected, pointing to a physical cable problem. Remember the memory tip: “Pink means no blue—check the cable’s view.”
220-1201 Display Devices Troubleshooting Practice Question
This 220-1201 practice question tests your understanding of display devices troubleshooting. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer.

Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
The video cable is not fully seated or has a bent pin.
A pink tint on one monitor while the other looks normal suggests a loose or damaged video cable, specifically a missing blue color channel. VGA cables are prone to this, but even HDMI or DisplayPort cables can have pin issues. Swapping cables can confirm.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A practitioner preparing for the 220-1201 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
