Difficulty: EasyVideo, Display, and Projector Issues

A technician is setting up a newly connected LCD monitor for an office workstation. The user reports that text and desktop icons appear blurry and stretched, despite the monitor displaying normal colors and brightness. Upon reviewing the system settings, the technician notices that the operating system display resolution is set to 1280×7201280 \times 720, while the monitor manufacturer lists a physical panel specification of 1920×10801920 \times 1080. Which of the following is the BEST action to resolve the image quality issue?

  1. Adjust the operating system display settings to match the monitor's native resolution of 1920×10801920 \times 1080.Answer
  2. B
    Replace the display panel's internal CCFL backlight inverter board.
  3. C
    Replace the graphics card due to overheating video memory (VRAM).
  4. D
    Replace the display cable with a higher bandwidth video cable to support digital signals.

Answer

Adjust the operating system display settings to match the monitor's native resolution of 1920×10801920 \times 1080.
LCD monitors possess a fixed matrix of physical pixels known as native resolution. When the operating system outputs a non-native resolution (such as 1280×7201280 \times 720 on a 1920×10801920 \times 1080 panel), the display hardware must interpolate pixel data across multiple physical pixels, resulting in blurry text and distorted graphics. Adjusting the OS display settings to match the monitor's native resolution restores crisp, clear visual output.

Step-by-Step Solution

1
Identify the physical specifications of the monitor display panel.
The monitor has a native hardware resolution of 1920×10801920 \times 1080.
LCD panels are engineered with a fixed physical matrix of pixels.
2
Compare the configured operating system output resolution with the monitor specifications.
The OS resolution (1280×7201280 \times 720) does not match the monitor's native resolution (1920×10801920 \times 1080).
Non-native resolutions require scaling (interpolation) across physical pixels, creating a fuzzy, stretched image.
3
Reconfigure the operating system display settings to 1920×10801920 \times 1080.
Text, icons, and graphics map 1:1 with physical pixels, rendering crisp and clear images.
1:1 pixel mapping eliminates interpolation artifacts and restores sharp visual quality.
