Another reason behind the flickering is incorrect refresh rate settings. Most monitors work with 60 Hz refresh rate. The newer models that are specially designed for gaming purposes have higher refresh rates as well. Therefore, you need to see the recommended refresh rate of your display and set it accordingly from the settings.

You can find this by applying some pressure on the affected area and see if the lines change in any way. If so, your LCD is damaged and it would need replacement. Therefore, the problem lies with the hardware. However, you may check the display settings from the control panel to check if everything is set at the recommended level. Always keep your display drivers updated and check that the graphics card is working properly as well.

  • Dead pixels

This issue is also faced by a lot of people in which a black dot or how to fix black spot on lcd screen starts appearing on the screen permanently.

However, there is a risk in this procedure because you may damage the screen unknowingly which will put a large bill in your pocket. The best way to deal with dead pixels is to wait and keep using the device unless it does not spread more to the screen.

  • Cracks and Spots

If you see a crack or blotch on screen which is significantly different than other colours on the display, it means that the LCD has gone through some physical damage. It can result due to the monitor falling off, liquid splashes on screen, sharp item hitting the screen or any similar event. Unfortunately, this means that you would need to replace the display because it is not possible to repair such damages. The internal components of the screen get damaged which are mostly not repairable.

  • Buzzing Sounds

Have you heard a slight buzz while you are working on your computer? It is most probably caused by a problem in the backlights of the display. The older monitors used fluorescent lighting tubes which are known to malfunction easily. The LED monitors have become much better in their efficiency and reliability but the power fluctuations can cause sounds in them as well. Try to keep a voltage regulator with the computer if there are frequent disruptions in power.

  • Incorrect Resolution

Have you experienced a change in screen’s resolution or brightness? The major reason behind it is the graphics card. There may be issue in the graphics driver which can be resolved by a software update or re installation. If the problem is still there, then you would need to get a new graphics card for your device. Sometimes, you may need to change the port if other components are working fine.

You need to check the main power supply of your house and see that the circuit breaker does not trip frequently. If so, the issue is with the main electricity. Another cause of the screen shutting down is the overheating of the device. The processor may overheat due to faulty fan or other reasons which you would need to sort out. You can check this easily by touching the laptop or PC’s casing after it turns off. If it feels very hot, the internal components are overheating and the display shuts off automatically to prevent it from further damage.
