One of the most common mistakes when connecting a monitor (primary or additional) is No Signal on the screen. It’s also one of the most accessible problems you can solve. If you get this type of message on your screen, your monitor is on, but your computer is not sending any visual data to the monitor.

To correct the error without a signal,

  1. Check the cable connections: A loose contact in the monitor’s cable connections can cause the monitor to display a No Signal message. Check that you have connected the cables correctly. You can also remove or unplug the cable and plug it back in. Check that your monitor is now correctly displaying your Windows screen.
  2. Restart your monitor: this means turning the screen off and on again. You can turn off your monitor and turn it back on after a few seconds to see if the problem persists. Your monitor should now recognize the video input and display it correctly
  3. Let Windows detect the monitor: If you use a secondary monitor, your monitor may not display a signal if Windows did not detect your computer’s monitor display. So that Windows recognizes your second monitor,

Right-click on your desktop.

From the pop-up menu that appears, choose Display Settings.

  2. Update your drivers: Make sure you are running the latest drivers (graphics drivers). Otherwise, you’ll need to update your drivers to make sure your screens are working correctly.
  3. Change your data cable: You should consider replacing your data cable with alternatives like HDMI, especially if you are using an old data cable like VGA.

2. Flashing or Flickering

If your cable is not connected correctly, the screen may flicker. If this continues even after checking your wired connection, the issue may be related to an incorrect refresh rate. Typically, LCD monitors use a refresh rate of 59 or 60 Hertz, while some high-end monitors use 75, 120, or even 144 Hertz.

  1. Access display settings (same as one of the methods above).
  2. Select Advanced display settings.

4. Dead pixels

A dead pixel or a stuck pixel is a hardware failure. Unfortunately, you can’t completely solve it. A stuck pixel is glued to a single color, while dead pixels are black.

Use software: some stuck pixels will be automatically repaired after some time. While stuck pixels are hardware problems, a specific software can hide them. For example, the Pixel Undead tool cycles colors. Many users can use this tool to fix stuck pixels.

Collotype: Some users report that the collotype can repair dead pixels on the screen in the damaged area. You can try this. However, be very careful as it can sometimes make the problem worse.

5. Vertical lines

Single or multiple vertical lines (black or solid) may appear on your screen for various reasons. If you have vertical lines, the suggested solutions may help. Connect your monitor to another computer. If the lines are still visible, you will need to replace your monitor or its LCD screen.

6. Wrong resolution

In this case, the problem is with your graphics card driver. Try updating it to the latest version and setting the screen resolution to the recommended settings.

7. Shutoffs

If your monitor turns off frequently, it means that your monitor is not receiving enough power. Make sure your monitor is providing the performance it needs to function correctly. It could also be due to overheating of the monitor or the AC adapter.

 8. Cracks and stains

If your monitor has a dark stain or a visible crack, it’s time to replace it. Your monitor’s LCD screen is probably damaged. You cannot replace it for free as this type of damage is not covered by the warranties of most companies.


If you ever experience white noise on your monitor screen, it may be due to the monitor’s backlight. You can adjust the screen brightness to different levels and see if the problem persists. In this case, you may need to replace your monitor. Most manufacturers replace it under warranty. If your warranty has expired, you can try replacing only the backlight bulbs at a local service store.
