How to Fix Computer Monitor Display Problems
What are some common problems with monitor displays?
Your computer monitor display can experience many problems. Some of them are no signal errors, distortion, flickering, dead pixels, cracks, or vertical lines. You can solve some of the issues yourself, and some will need you to replace your monitor. Check out the full article to learn how to fix computer monitor displays and determine when to replace your monitor.
Here are some common problems and how to solve them. Read the article and fix your errors now!
1. No Signal
One of the most common errors while connecting a monitor (either a primary one or an additional monitor) is the No signal message on the screen. Also, this is one of the easiest problems you can fix. Receiving this kind of message on your screen means that your monitor is on, but your computer is not sending visual data to the monitor.
To fix the no signal error,
a. Check your cable connections: Loose contact in monitor cable connections can cause the monitor to show a No signal message. Verify if you have connected the cables properly. You can also remove or unplug the cable and plug them in again. Check if your monitor now displays your Windows screen properly.
b. Restart your monitor: This simply means turning your monitor screen off and on. You can simply power off your monitor and power it on after a couple of seconds to check if the problem persists. Your monitor should now recognize the video input and display it properly.
c. Make Windows detect the monitor: In case you use a secondary monitor, your monitor may show no signal if Windows did not detect your computer monitor display. To make Windows detect your second monitor,
- Right-click on your desktop.
- From the pop-up menu that appears, choose Display settings.
- Choose to Detect in the Display settings window.
Your computer should now detect the monitor, and your problem should vanish by now.
d. Change your graphics card port: If you use a graphic card with several output ports, try changing your port. If you have a damaged port, switching to another port will help you fix the issue.
e. Update your drivers: Make sure you run the latest drivers (Graphics drivers). If not, you must update your drivers to ensure the perfect functioning of your monitor displays.
f. Change your data cable: You need to consider changing your data cable to alternatives like HDMI, especially if you use a very old data cable such as VGA.
2. Flashing or Flickering
You may experience screen flickering if your cable is loosely connected. If this continues even after you check your cable connection, the problem may be due to an improper refresh rate. Generally, LCD monitors use a 59 or 60-hertz refresh rate while a few premium ones use 75, 120, or even 144 hertz.
1. Go to Display settings (as we did in one of the above methods).
2. Choose Advanced display settings.
3. Choose Display adapter properties.
4. In the dialog box that opens, adjust the refresh rate, and click OK.
Your screen may sometimes flicker due to an irregular power supply. So you can check your power supply as well.
Distortion in the color balance or display of your screen is also a common problem with computer monitor displays. To get rid of distortion, you can check and replace any damage to any monitor cables.
1. Open the Display Settings.
2. Set your Display resolution to Recommended.
Uninstalling and reinstalling the driver:
1. In the start menu, search Device Manager and open it.
2. Click and expand the Display adaptors option.
3. Right-click on your respective video card.
4. Click the Uninstall device option.
5. Now Restart your computer and Reinstall the device driver again.
6. Download the most recent driver for your system from the official website.
You can also try updating your driver before uninstalling it. If that fixes your issue, you don’t need to uninstall and reinstall the driver.
4. Dead Pixels
A dead pixel or stuck pixel is a hardware error. Unfortunately, you cannot fix it entirely. A stuck pixel is one that is stuck with a single color while the dead pixels are black.
Use a Software: Some stuck pixels get fixed automatically after a certain period. Though stuck pixels are hardware problems, a specific software can hide them. For example, the Undead Pixel tool cycles the colors. This tool may work for many users to fix stuck pixels.
Mild press: Some users report that pressing the screen mildly over the damaged area can fix the dead pixels. You may try out this. But do this very carefully, as this could make the problem worse sometimes.
Replace your monitor: If several pixels on your screen are dead, you need to consider replacing your computer monitor display problems. You might replace it free of cost if it is a manufacturing defect or it occurs within the warranty period.
5. Vertical Lines
You can see a single or a set of vertical lines (either black or single-colored) on your screen due to various reasons. You can find the recommended solutions helpful in the case of vertical lines. Connect your monitor with a different computer. If the lines are still visible, it is time to replace your monitor or its LCD panel.
6. Incorrect resolution
If you experience this, the problem is with your graphics card driver. Try updating it to the latest version and set your display resolution to the recommended settings.
If your monitor shuts off by itself often, it means that your monitor is getting insufficient power. Make sure your monitor receives the required power to run smoothly. Also, overheating of the monitor or the power adapter can cause this.
8. Cracks and Spots
If your monitor has a visible dark spot or a crack, it is time that you replace your monitor. The LCD panel of your monitor is probably damaged. You cannot replace it free of cost as this type of damage is not covered by the warranty policy of most companies.
If you ever come across a white noise in your monitor display, it may be due to the monitor’s backlight. You can adjust your screen brightness to various levels and check if the problem persists. If it does, you may have to replace your monitor. Most manufacturers will replace this under warranty. If your warranty period is over, you can try replacing only the backlight bulbs in a local servicing store.
