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.
All the monitor troubleshooting tasks I did do not require me to open up my computer, monitors case, use any tools, or any complicated software.
You can 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. Turning it on and off did not work for fixing my monitor problem where it was displaying a blue color tint on the entire screen.
2. I also tried shutting down my computer and un-pluging my monitor video and power cable from the case to see if the cable has any damage on the connector or cable. I replugged in the cable and make sure the cable is firmly plug into the monitor and the cable is not tangled. I re-plugged 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.
6. Replacing the video cable like a HDMI, VGA, or DVI cable with another cable from another computer, or a new one from the store may fix your video problem if it is related to your video cable.
Troubleshooting laptop LCD monitors can be more difficult since everything is installed internally 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 plugged into your laptop’s video port. If you are also experiencing the same blue video tint problem on your external monitor, your video card might be going bad, or the video drivers needs to be reinstalled.
