Recently, I got a blue tint on my LCD monitor which suddenly appeared after turning on my monitor. The blue tint is a light blue cyan or aqua blue shade. It was rather annoying to look at, but easy to fix for me. I haven’t experience my monitor turning blue since I fix it by doing some very simple tasks.
These tasks do not require you to open up your computer, monitors case, use any tools, or any complicated software.
You first try adjusting your monitor color settings by using the control panel program built into all monitors. Some monitor drivers also let you adjust your monitor’s color settings within Windows.
1. The first thing I tried was turning the monitor Off, and ON to see if it fixed the problem. It did not work for fixing my monitor.
2. I shut down my computer and unplug my monitor video and power cable from the case to see if the cable has any damage on the connector or cable which it did not. I replugged in the cable and make sure the cable is firmly plug into the monitor and the cable is not tangled. I replugged in my monitor power cable to the wall outlet and turned my computer on. The blue tint is gone now, and my LCD colors are back to normal.
3. You can also try replacing the monitor cable, or testing your monitor on another computer if my first two steps did not work for you.
4. You can also use another monitor like an old tube CRT to see if it also has a blue tint. If it does, then it is most likely a video card problem with your computer.
5. You can also try uninstalling your video card drivers and installing the latest version of your video card drivers.
Troubleshooting laptop LCD monitors can be more difficult since everything is internal including the wires, power cables for the monitor. You can try using a known good monitor to test the video card by plugging the monitor into the video output VGA plug, and see if you are also experiencing the same problems on your external monitor plug into your laptop. If you are, then your video card might be going bad. If not, it is best to take your laptop to a shop to have the monitor replaced.
