220-1201 Practice Question: A user's all-in-one PC has a touchscreen that is…
A user's all-in-one PC has a touchscreen that is not responding correctly. The technician calibrates the touchscreen, but the issue persists. The technician then notices that the screen is slightly misaligned with the bezel. What is the most likely cause?
⚠ Common exam trap
CompTIA A+ often tests the distinction between software-based calibration issues and hardware displacement, where candidates mistakenly choose driver or firmware problems when the symptom is a visible physical misalignment.

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 LCD panel has shifted inside the chassis.
The physical misalignment between the screen and the bezel indicates that the LCD panel has physically shifted inside the chassis, which is a common issue in all-in-one PCs where the panel is mounted directly to the frame. This shift causes the touch input coordinates to be offset from the display output, and recalibration cannot compensate for a hardware displacement. The digitizer (touch sensor) is likely still functional, but its alignment relative to the LCD is now incorrect.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The touchscreen driver is corrupted.
Why it's wrong here
A corrupted driver would likely cause no response or erratic behavior, not a consistent offset.
- ✗
The digitizer is failing.
Why it's wrong here
A failing digitizer would cause dead zones or random inputs, not a consistent misalignment.
- ✓
The LCD panel has shifted inside the chassis.
Why this is correct
A physical shift of the LCD panel causes the touch coordinates to be offset from the display, which calibration cannot correct.
- ✗
The operating system needs a touchscreen firmware update.
Why it's wrong here
Firmware updates can fix bugs, but not physical misalignment.
