The correct first step is to install the touchscreen driver from the manufacturer. This is because a touchscreen monitor relies on two separate data paths: the HDMI cable delivers the video signal, while the USB cable carries the touch input data back to the computer. If the display works but touch input is not recognized, the video connection is fine, but the system is likely missing the driver that translates the USB touch data into usable commands. On the CompTIA A+ Core 1 220-1201 exam, this scenario tests your understanding of multifunction peripheral setup and the distinction between display and input connections. A common trap is to immediately suspect a faulty USB cable or port, but the most frequent cause is a missing or incorrect driver, especially with point-of-sale systems. Remember the memory tip: “Video is seen, touch is unseen—driver makes the USB clean.”

Correct answer & explanation
✓
Install the touchscreen driver from the manufacturer
Touchscreen monitors often require both video (HDMI) and data (USB) connections. The USB cable provides the touch data to the computer. If the driver is missing or the USB connection is faulty, touch input won't work. The first step is to verify the USB connection and install the correct driver.
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.
✗
Ensure the HDMI cable is securely connected
Why it's wrong here
The display works, so the HDMI connection is fine; the issue is with touch data, not video.
✓
Install the touchscreen driver from the manufacturer
Why this is correct
Touchscreens require a driver to interpret touch signals; without it, the USB data is not recognized as input.
Clue confirmation
The clue word "first" in the question point toward this answer.

Read the scenario before looking for a memorised answer.
✗
Replace the USB cable with a higher-speed version
Why it's wrong here
A standard USB 2.0 cable is sufficient for touch data; speed is not the issue.
✗
Calibrate the touchscreen in Windows settings
Why it's wrong here
Calibration is done after the driver is installed; without the driver, the touchscreen won't appear in settings.

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.
