The answer is to check if the touchscreen driver is installed in Device Manager. This is the correct first step because a non-responsive touchscreen on a working display almost always points to a missing or corrupted driver rather than a hardware failure; the display itself is functional, so the issue lies in the software layer that translates touch input into system commands. On the CompTIA A+ Core 1 220-1201 exam, this scenario tests your understanding of the OSI model’s driver layer and the troubleshooting methodology—specifically, verifying driver installation before moving to hardware diagnostics. A common trap is immediately assuming the touchscreen is defective or needs calibration, but the exam emphasizes checking Device Manager first for any yellow exclamation marks or unknown devices. Remember the mnemonic: “If the screen lights but the touch won’t write, check the driver before you fight.”
220-1101 Display Devices Practice Question
This 220-1201 practice question tests your understanding of display devices. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A technician is setting up a new all-in-one PC for a reception desk. The PC has a touchscreen display. After installation, the touch function does not respond. The technician has verified that the display works and the OS is loaded. What should the technician check first?

Correct answer & explanation
✓
Check if the touchscreen driver is installed in Device Manager
Touch functionality often requires a specific driver or calibration. The display works, so the issue is likely driver-related, not hardware. Checking device manager for missing drivers is the logical first step.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Replace the touchscreen digitizer
Why it's wrong here
This is a hardware repair step, not a first check, especially when drivers are a common cause.
✓
Check if the touchscreen driver is installed in Device Manager
Why this is correct
Missing or incorrect drivers are the most common cause of touchscreen non-functionality.
Clue confirmation
The clue word "first" in the question point toward this answer.

Read the scenario before looking for a memorised answer.
✗
Clean the screen with a microfiber cloth
Why it's wrong here
Dirt rarely causes total touch failure; this is unlikely to resolve the issue.
✗
Disable and re-enable the touchscreen in BIOS
Why it's wrong here
BIOS settings are less likely the cause; driver issues are more common.
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.

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.
