How to Fix a Dark Gradient on Your Acer Monitor


What could cause an Acer monitor to display a dark gradient from right to left?

I have an Acer monitor that shows a gradual decrease in brightness from the right side, where the image is clear, to the left side, where it is completely black. This occurs regardless of the input source. I have attempted the common troubleshooting steps such as resetting the monitor settings and disconnecting and reconnecting the cables, but nothing has worked. Do you have any suggestions on how to fix this issue or is the monitor beyond repair?


If you have an Acer monitor that shows a dark gradient from right to left, you might be wondering what is causing this problem and how to fix it. A dark gradient on your monitor can affect your viewing experience and productivity, especially if you work with graphics or colors. In this article, we will explore some of the possible causes and solutions for this issue.

Possible Causes of Monitor Discoloration

There are several factors that can cause your monitor to display a dark gradient or other forms of discoloration. Some of the most common ones are:

  • Hardware malfunctions: A faulty graphics card, loose connections, or damaged cables can interfere with the signal transmission between your computer and your monitor, resulting in a discolored display. You can check your hardware components by testing them with another monitor or device, or by replacing them with new ones.
  • Software setbacks: Outdated or incompatible display drivers can also lead to monitor discoloration. Display drivers are software programs that control how your computer communicates with your monitor. You can update your display drivers by visiting the manufacturer’s website or using a driver updater tool.
  • Monitor age: All monitors, especially old-school LCDs, experience color fading over time due to natural wear and tear. Their backlighting system can deteriorate, leading to color shifts or uneven brightness across the screen. You can try to adjust the brightness and contrast settings on your monitor, or consider buying a new one if the problem persists.
  • Overheating: LCD monitors have a limited operating temperature range between 0°C (32°F) and 50°C (122°F). Excessive heat can affect your monitor’s performance and cause discoloration. Factors such as insufficient ventilation, proximity to heat sources, or prolonged use without adequate cooling can lead to overheating and subsequent color discrepancies. You can prevent overheating by placing your monitor in a well-ventilated area, away from direct sunlight or other heat sources, and by using a cooling fan or pad if necessary.
  • Magnetic interference: Strong magnetic fields from nearby speakers, unshielded electronics, or magnets can disrupt the liquid crystal display on your monitor, resulting in color distortion. You can avoid magnetic interference by keeping your monitor away from any magnetic objects, or by using shielded speakers or cables.
  • Environmental factors: Persistent exposure to sunlight or extreme conditions like high humidity or excess dust can affect your monitor. Long-term sun exposure can lead to discoloration, while moisture and dust can infiltrate the monitor and distort colors. Extreme heat can permanently damage and destroy liquid crystals. You can protect your monitor from environmental factors by keeping it in a dry, clean, and moderate environment, and by using a screen protector or cover when not in use.
  • Possible Solutions for Monitor Discoloration

    If you have identified the cause of your monitor’s dark gradient, you can try some of the following solutions to fix it:

  • Troubleshoot your hardware: If you suspect that your hardware components are faulty, you can troubleshoot them by following the steps in this [guide]. You can also contact Acer’s customer support or visit a local repair shop for further assistance.
  • Update your display drivers: If you think that your display drivers are outdated or incompatible, you can update them by following the steps in this [article]. You can also use a driver updater tool to automatically scan and update your drivers.
  • Adjust your monitor settings: If you believe that your monitor’s age or backlighting system is causing the dark gradient, you can try to adjust the brightness and contrast settings on your monitor. You can also use the monitor’s built-in calibration tool or a third-party software to fine-tune the colors and gamma levels on your screen.
  • Cool down your monitor: If you notice that your monitor is overheating, you can try to cool it down by turning it off for a while, placing it in a cooler area, or using a fan or pad to lower the temperature. You can also monitor the temperature of your monitor using a software tool or a thermometer.
  • Remove magnetic interference: If you detect that your monitor is affected by magnetic interference, you can try to remove the source of the magnetic field, or move your monitor away from it. You can also use a degaussing tool or a magnet to restore the colors on your screen.
  • Protect your monitor from environmental factors: If you observe that your monitor is exposed to sunlight or extreme conditions, you can try to shield it from them by changing its location, using a screen protector or cover, or cleaning it regularly.
  • Conclusion


dark gradient on your monitor can be caused by various factors, such as hardware malfunctions, software setbacks, monitor age, overheating, magnetic interference, or environmental factors. Depending on the cause, you can try some of the solutions mentioned above to fix your monitor’s discoloration. However, if none of these solutions work, or if your monitor is severely damaged, you might need to replace it with a new one. We hope this article has helped you understand and solve your monitor’s dark gradient problem.
