7 Troubleshooting Techniques for Monitor Discoloration & Distortion

Monitor issues could be a constellation of symptoms - so let's start with the easiest and begin to progress. You're like a doctor trying to diagnose a patient with a mysterious ailment. 

1) Restart Your Computer 

It might sound too simple, but a quick system restart is sometimes all you need. This tried-and-true method can solve temporary software glitches causing discoloration or distortion. A system restart will close any apps interfering with your display and give your computer a fresh start.

2) Time Out for Your Monitor 

Like all electronics, monitors can overheat, impairing their performance. Excessive screen time can overheat your monitor and cause a discolored or distorted display.

How can you tell if it's too hot? It might be overheating if your monitor:

  • Feels hot to touch. 
  • Randomly shuts off. 
  • Flickers. 
  • Displays pixel lines.

These symptoms could also indicate a graphics card working overtime or insufficient ventilation.

Here's What You Can Do: 

Switch off your monitor and count slowly to 15. Power it back on and check for improvement. If the issue remains, it's time for an extended break. Unplug the monitor and leave it for 30 minutes. This cooling period can reset your monitor and potentially resolve any overheating issues.

How to Stop Monitor Overheating: 

Here are a few options to consider: 

  1. Proper ventilation: Ensure your laptop or external monitor has adequate airflow. Avoid placing it in enclosed spaces or near heat sources such as radiators or direct sunlight. 
  2. Cooling pads: Investing in a cooling pad can help dissipate your device's heat. These pads provide additional air circulation, reducing the risk of overheating. 
  3. Monitor fans: Some monitors have built-in fans designed to keep them cool during prolonged use. Consider opting for a model that includes this feature if you frequently use your monitor for extended periods.  

3) Check the Cable Connections 

Ensure all cables connecting your monitor to your computer are securely plugged in. Loose or damaged cords can cause signal loss, resulting in screen distortion. Steps to take include:

  • Inspect the cable connections: Start by closely examining all the cables running from your monitor. Make sure they're securely connected without any loose ends or damage. 
  • Disconnect and reconnect: Unplug any loose cables from your monitor and PC and firmly reconnect them. But remember, don't bend, or force any connectors - that can cause further damage. 
  • Use digital connections: If possible, use digital video inputs like HDMI or DisplayPort. They're the gold standard, delivering better signal quality than analog options like VGA. Test different video input ports on your monitor. 
  • Keep Interference at Bay: Got other electronic devices near your monitor? They could be disrupting signal transmission. Clear the area around your monitor to prevent potential interference. 
  • Switch Displays: Connect your computer to another monitor to determine if it's a hardware issue.

4) Check Hardware Issues in Device Manager 

Windows 10 and 11 have an in-built tool for hardware management - the Device Manager, which can troubleshoot your graphics card or monitor for hardware issues. Device Manager is where you start when your monitor displays a bit wonky.

Don't Forget Your Monitor Settings 

Monitor drivers also need regular updates. Return to Device Manager, expand "Monitors," and update as necessary.

If your monitor displays as "Generic PnP," it uses a generic driver. A dedicated driver from your manufacturer provides better performance and more features. For Acer, enter your model number in the drivers and manual support section.

Remember, your display drivers are crucial for optimal visual performance. They ensure smooth, crisp visuals, making regular updates essential.

6) Adjust Brightness and Contrast Settings 

Once you have determined that the monitor discoloration is not caused by a hardware issue, it may be possible to correct it by adjusting your computer's display settings. Here are some steps you can take:

You can optimize color reproduction from your monitor's OSD (Onscreen Display) with its trove of settings. Here's what you need to do:

  • Navigate to OSD: Use the buttons on the front or side of your display to access the OSD menu. 
  • Reset to Factory Default: Set it to the original factory settings if in doubt. 
  • Color Calibration: Begin by calibrating your monitor's color settings. This process involves adjusting the red, green, and blue levels to achieve accurate colors on your screen. 
  • Brightness and Contrast: Adjust your monitor's brightness and contrast levels. Increasing or decreasing these settings can help alleviate discoloration issues. 
  • Resolution: Check that your monitor is set to its native resolution, which provides optimal sharpness and clarity. Lower resolutions may result in distorted or discolored images. 
  • Refresh Rate: If none of the above steps resolve the problem, consider adjusting the refresh rate of your monitor. A higher refresh rate can reduce flickering and improve image quality.

For instructions tailor-made for your monitor, check out your user manual or the manufacturer's website.

7) Run Windows' Built-in Troubleshooter
