Some of the most common computer monitor problems include blank screens, the monitor not turning on, and images being displayed in the wrong size or blurry. This happens even if you have a high-end monitor for your Macbook Pro or PC. Luckily, there are several easy steps you can take to troubleshoot these and other issues that will generally solve the problem.

Key Takeaways:

  • The most common cause of monitor problems is in the connections.
  • Adjusting display settings can fix images appearing improperly.
  • Some monitors require software to function properly.

Troubleshooting Common Monitor Problems

1. Restart Monitor

Restarting your electronics is always the best place to start when troubleshooting a problem. If there is an issue with your favorite computer monitor, turn it off completely and then back on again. Most displays have a power indicator light that will light up when it is on. If this light does not turn on after pressing the on/off button, your display is either dead or is not receiving power. If your display does turn on but is still experiencing issues, go through the same reboot process with the computer you’re connecting it to.

2. Check Connections

The next step in fixing any screen and operational issues with your display is to check all of your connections. You want to make sure that the electrical cable and the computer connection cable are both securely in place. The easiest way to do this is to unplug the display from the power source and from the monitor completely. Do the same with the cord to the computer. Then, resecure both cords tightly in the correct input ports.

3. Inspect For Physical Damage

If problems persist, check the screen, wires, and inputs for any signs of physical damage. For the display, look for any cracks in the body of the monitor or the screen. When inspecting the cables, look for any crimps in the wire, cuts, or fraying. Check the corresponding inputs to make sure that they aren’t loose or damaged.

Consequently, if there’s physical damage present your warranty should cover it. If you don’t have one yet, you’ll need to decide if the Asurion Amazon protection plan is worth it.

4. Adjust Settings

If images on your display appear but are the wrong size or blurry, you should go into your computer’s display settings to make adjustments. If your desktop image is either too small or too big for the monitor size, adjust the display’s resolution settings until you get a clear picture that fits the full size of your display. Here, you can also make sure that the computer is properly recognizing the monitor.

5. Install Updates

Some monitors require a driver installed on your computer to function properly. In some cases, installing or updating your monitor’s driver could solve connection and picture issues. To find out more about your display’s driver and download the latest version, go to the manufacturer’s website for your monitor and search for your display model. The user manual that came included with the screen should have instructions on proper driver installation as well.
