1. Causes and Solutions for Blurry Computer Screen
Blurry computer screen is a prevalent issue when using and working with computers. There are numerous reasons causing the gradual blurriness of computer screens. The following article will provide readers with some main causes and solutions for fixing blurry computer screen issues.
Reasons for Blurry Computer Screen
Improper Screen Brightness Settings
Adjusting the screen brightness too low can lead to the computer screen becoming blurry, dim, and difficult to see. This is a common issue caused by people enabling power-saving mode but failing to revert it back or it may have been set as default by someone else.
Faulty High-Voltage Backlight
A faulty high-voltage backlight results in the computer screen appearing dimmer and blurrier than when it was initially used. Most screens perform well at 1000 cd/m2 brightness. If the high-voltage backlight is faulty or flickering, it can reduce brightness below 1000 cd/m2, gradually blurring the computer screen despite adjusting brightness settings.
Poorly Operating High-Voltage Inverter
The high-voltage inverter, also known as LCD inverters, generates the voltage to illuminate the backlight. Similar to blurry or dim laptop screen issues, if the high-voltage inverter operates poorly, it can result in a dark and blurry laptop screen.
LCD Screen Malfunction
Your screen might be past its prime or may have suffered from accidental drops, wear and tear over extended usage could lead to laptop screen issues like flickering, flashing, shaking, dimming, blurring...
Incorrect Screen Refresh Rate
Setting the screen refresh rate accurately is crucial for optimal performance and sharpness. Typically, the refresh rate should be set at 50, 60, 70, or 75Hz depending on the screen type for the best results.
Fixing Blurry Computer Screen
Firstly, check the brightness settings on your screen. If it's too low, readjust it to match the original settings. If you're unsure how to adjust screen brightness, you can refer to a guide on adjusting computer screen brightness.
Additionally, please verify if the screen refresh rate is correctly set. If not, reset it by right-clicking on the screen => Properties => Setting => Advanced => Monitor, then adjust it accordingly. It should typically range from 50 to 75Hz. Make sure to reset it.
Moreover, to resolve blurry computer screen issues caused by faulty screen high voltage, flickering, or defective high voltage boards, bring your device to reputable warranty centers or repair shops for diagnostics, repairs, or replacements.
