I notice sometimes one of my older LCD monitors, which uses a VGA video cable to connect to my PC, sometimes has a weird light blue tint over the entire video on my monitor for some reason. The blue tint is very light like a cyan or aqua blue color, and makes my monitor look more blue. I think it maybe related to the back light on the LCD monitor which uses the older fluorescent tube style back light.
Getting rid of the light blue cyan colored tint on my monitor is pretty simple, and does not require any special tools, or advance technical skills.
I first need to shutdown my computer, and remove the monitor’s power cable, and video cable from the wall. The next thing I do is press on the power button on the monitor a few times to get rid of any electricity which may still be inside my monitor. Also, check to see if the video cable is not damaged while your video cable is unplugged.
When I am done pressing the power button on my monitor s few times, I need to plug in the monitor’s video cable back into my desktop, and the monitor’s power cable back into my home’s power outlet.
Sometimes fixing discoloration problems with a monitor can be as simple as unplugging it from your desktop computer, and plugging it back in.
You can also see if adjusting your monitor’s color settings with the built-in color adjustment program in some monitors which you can use by pressing the buttons on the monitor, or using the color adjustment program which is found in your video card settings programs in Windows and other operating systems can fix your problems with colors looking less accurate. A badly configured color setting in your monitor, or video settings maybe causing your monitor to display your monitors colors incorrectly.
Lastly, testing your monitor on another computer would help you find out if it is your monitor or computer which is broken. If the monitor works on your other computer, it could mean your computer’s video card is broken, and needs to be replaced. If you do not have another computer, you can try another monitor video cable, monitor on your PC to see if other video cables, and monitors also create the same video problems. You can also buy an inexpensive PCI-Express video card which you can buy for $40 or less, and install it on your desktop PC to see if replacing the video card fixes your color display problems by installing a new video card onto your PC to replace your old video card which may not be displaying colors correctly anymore because of damaged on its internal parts.
If you are trouble shooting and repairing a laptop’s monitor with a weird blue tint covering it, you need to shutdown the laptop, remove its battery, and power adapter charging cable before pressing down the power button a few times to see if pressing down on the power button while there is no power fixes your problem with a blue-tint on the monitor showing up. On laptops with no removable battery, you can use the laptop until it has no battery life left in the battery, and press the power button to drain the remaining electricity which may still exist in your laptop. For All-in-One desktop computers with the monitor built-into the desktop, you could see if shutting down your computer, and unplugging it from your home’s power for a few minutes, pressing on the power button a few times while it is unplugged, and re-plugging the power back in fixes your monitor colors.
But, I only experience a light blue tint showing up on an older LCD monitor I owned which uses a VGA port, and the back light uses the older fluorescent tube back lights instead of LED, OLED, and AMOLED which is more popular on newer computers like laptops, tablets, gaming handheld consoles, and newer All-In-One Desktops. All the laptops, and tablets I owned never had color display problems, so I think the color display problems are less common on newer display types found in laptops, tablets, and newer desktop monitors.
Troubleshooting and Repairing a monitor showing a weird blue tint over the entire video is very simple to fix. It can be as simple as un-plugging the monitor, and re-plugging it back into your desktop computer’s videocard, and home’s power outlet.
