Why Does My Monitor Have a Blue Tint?

I’ve recently been frustrated by the blue tint on my monitor. I couldn’t figure out why it was there and how to get rid of it. After doing some research and testing, I’m here to share my experience and the solutions I discovered to help anyone else out there who’s struggling with the same issue. In this blog post, I’m going to explain why your monitor may have a blue tint and the best ways to fix it.

Not only are blue-tinted monitors an indication of a hardware issue, but it could be a problem stemming from your monitor’s driver.

Apart from that, fixing a blue screen is not only crucial for your monitor’s sake but for your eye health as well. Prolonged exposure to a blue screen can cause retinal damage over time.

4. App InterferencesUninstall suspected app, then reinstall the updated version

Reason #1: Outdated Monitor or Graphics Driver

An outdated graphics driver could be the reason why your monitor is turning blue on you. Luckily, this only calls for a simple update, which can be completed by the steps mentioned below.

How to Update Drivers

  1. Visit your driver’s manufacturer site such as Nvidia and enter your driver’s information.
  2. Locate your driver model and access the latest update then download it.
  3. Press the Windows key and the “R” key.
  4. Type “devmgmt.msc” in the space given and click “OK.”
  5. Click on the “Monitors” option.
  6. Right-click on the monitor you use and choose “Properties.”
  7. Select the “Driver” tab and click on “Update Driver.”
  8. Choose “Browse my computer for drivers.”
  9. Navigate to the previously downloaded driver update.
  10. Follow the on-screen instructions.
  11. Restart your monitor.

Reason #2: Hardware Issues

Another common reason why your monitor is blue-tinted could come from your hardware. This includes your monitor cables, pins, and screen.

Overheated Screen

To make sure it’s an overheated screen issue, open a few tabs on your monitor. Then, leave them open for a few moments.

Inspect your screen’s temperature to the touch. If it feels hot already from all sides, then you’re likely dealing with overheating. In this case, you’ll want to shut down the monitor so it doesn’t malfunction further.

This issue could be caused by dust build-up in the monitor’s hardware system or a hot and humid environment. To avoid overheating, you can clean your monitor’s vents with an air spray or PC vacuum.

Monitor Cables

Monitor cables connect three primary colors from the Graphics Processing Unit (GPU) to the monitor. These are red, green, and blue. In some cases, two of the colors, namely, red and green, may not be reaching your screen due to a faulty VGA cable.

In this scenario, you can inspect your cable’s pins and make sure they’re not bent. If they’re broken, then you may need to consider purchasing a new cable.

How to Check Disk Utility

Aside from checking your cables and screen, you can run a check disk utility to scan your hard drive for any errors. Here’s how you can do it.

  1. Go to “Start” or the Windows icon and type “Command Prompt.”
  2. Click on the option presented. A black screen should appear.
  3. Key in “chkdsk.”
  4. Press “Enter.”
  5. Wait for the scanning process to be complete before exiting the tab.
  6. Restart the PC.

Reason #3: GPU Color Setting Deviated from Default

In addition to hardware issues, your GPU settings may be misconfigured. Fortunately, you can easily solve this issue by resetting the monitor’s color settings. Check out how to do so below.

How to Change GPU Color Setting

  1. Locate your GPU control panel. For instance, if you’re operating with Nvidia, right-click on your desktop page and click on “Nvidia Control Panel.”
  2. Find “Settings” then move to “Display.”
  3. Locate the color setting and change them back to default.

How to Change PC Color Setting

  1. Navigate to your start button and search “colorcpl.”
  2. After selecting the option, go to the “Advanced” tab.
  3. Enable the default color system by clicking ‘Restore Defaults.” Otherwise, you can manually go through each option and set it to its default standard.
  4. Restart the PC and check for changes.

Reason #4: App Interferences

In some cases, some downloaded applications may be tampering with your screen’s color settings. If you suspect an application that’s causing this issue, then we suggest uninstalling it and then updating it to check if it’s the culprit.

How to Uninstall a Suspected App

  1. To start, go to your “Task Manager.”
  2. Select the “Processes” tab and check which applications are consuming significant space.
  3. Then, navigate to your “Control Panel.”
  4. Choose “Programs and Features”.
  5. Locate the suspected app and disable it.
  6. Restart your PC.
  7. Reinstall the most up-to-date version of the app.

To Conclude

Why does my monitor have a blue tint? Simply put, your monitor could be facing various issues. The problem could be rooted in its hardware and the cables need replacing. Alternatively, your GPU driver could use an update.

The good news is that these problems could be mitigated in a few steps that involve updates, replacements, and setting reconfiguration.

If the blue tint persists, then we recommend speaking to a professional at a repair shop. Alternatively, you can opt for a new screen, especially if the old one keeps overheating.
