The correct first step is to adjust the color settings in the monitor’s on-screen display (OSD). This is the right move because LCD monitors and older CRT monitors use fundamentally different display technologies and color gamuts; an LCD’s default settings often produce a cooler, less saturated image that appears washed out to someone accustomed to a CRT’s richer phosphor-based colors. On the CompTIA A+ Core 1 220-1201 exam, this scenario tests your understanding of display calibration and the troubleshooting order—always start with the simplest, most accessible adjustment before moving to driver updates or hardware replacement. A common trap is jumping straight to reinstalling graphics drivers or replacing the monitor, but the OSD’s color, brightness, and contrast controls are the quickest fix for a washed-out LCD. Remember the memory tip: OSD first, drivers second—the monitor’s own menu is the fastest path to accurate color.
220-1201 Display Devices Practice Question
This 220-1201 practice question tests your understanding of display devices. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. 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 installing a new LCD monitor for a user who does photo editing. The user complains that colors appear washed out compared to their old CRT monitor. What should the technician adjust first?

Correct answer & explanation
✓
Adjust the color settings in the monitor's on-screen display.
LCD monitors often have different color gamuts and settings than CRTs. The most straightforward fix is to adjust the color calibration settings in the monitor's OSD or OS to improve color accuracy.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
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 video cable with a DVI cable.
Why it's wrong here
Changing the cable type won't fix color accuracy issues; it only affects signal transmission.
✗
Update the graphics driver.
Why it's wrong here
While updating drivers can fix some issues, washed-out colors are usually a monitor setting or calibration problem.
✓
Adjust the color settings in the monitor's on-screen display.
Why this is correct
Adjusting color settings like brightness, contrast, and color temperature can correct washed-out colors.
Clue confirmation
The clue word "first" in the question point toward this answer.
Related concept
Static NAT maps one inside address to one outside address.
✗
Set the resolution to the monitor's native resolution.
Why it's wrong here
Native resolution affects sharpness, not color accuracy.
Common exam traps
Common exam trap: NAT rules depend on direction and matching traffic
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Detailed technical explanation
How to think about this question
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
KKey Concepts to Remember
Static NAT maps one inside address to one outside address.
PAT allows many inside hosts to share one public address using ports.
Inside local and inside global describe the private and translated addresses.
NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
→Identify inside and outside interfaces first.
→Check whether the scenario needs static NAT, dynamic NAT or PAT.
→Do not confuse NAT matching ACLs with normal packet-filtering intent.
Key takeaway
NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Real-world example
How this comes up in practice
A small business has 20 workstations on the 192.168.1.0/24 network and one public IP from its ISP. The router uses PAT (NAT overload) so all 20 devices share one public address using different source ports. NAT questions test whether you understand the four address terms and which direction each translation applies.
