LCD and LED

Correct Answer: Failing backlight

Uneven brightness on an LCD monitor is usually caused by a failing backlight. Loose VGA cables, incorrect color adjustments, and malfunctioning graphics cards can result in other display issues, but not uneven brightness. Broken display panels and damaged capacitors may cause other display issues but are less likely to be the cause of uneven brightness.

Correct Answer: Update graphics card driver

Updating the graphics card driver is the most likely solution to improve text crispness on an LED monitor. Graphics drivers control how the computer communicates with the display, including text rendering. Outdated or incorrect drivers can cause text to appear blurry or pixelated. Updating to the latest driver version often resolves these issues by optimizing text rendering algorithms and ensuring proper communication between the computer and monitor. This solution addresses the root cause of the problem at the software level, rather than attempting to compensate for it through monitor settings or hardware changes.

Correct Answer: Image retention

Image retention is the most likely cause of a persistent image on an LED monitor. This occurs when an image is displayed for an extended period, causing the pixels to retain a 'ghost' of the previous image even when the screen content changes. Pixel burnout refers to permanent damage to individual pixels, which would result in dead or stuck pixels rather than a persistent image across the entire screen. A loose VGA cable or broken display panel would typically cause distorted, flickering, or no image at all, rather than image retention.
