- The cause of the screen cable error can also lead to the situation of the LCD screen being jerky. The screen cable, whether laptop or desktop, after a period of use can be worn out, the contact pins are poor or damaged due to impact. If on the computer we just need to remove the cable and replace the new cable, on the laptop you have to take it to the store to check and fix this common error on the LCD screen.
- If it is not due to the Cable, it could also be caused by the VGA itself , including the VGA port and the internal Chip. The port could be oxidized, and the internal Chip could also be due to usage errors, overheating, or improper cleaning. Of course, in cases like this, we can only take it to the warranty center for repair.
- The final cause of the LCD screen shaking can also be due to the screen itself being faulty due to external impacts, possibly due to collision with a hard object or being dropped. And there is no other way to fix it than to take it to a warranty center for repair.
2. Screen color stripes error

The color striped screen error is also quite common on old screens and there are many causes. However, it focuses on 2 problems: the screen and the graphics VGA .
- The main cause of the color stripe display is the error of the VGA graphics. This color stripe can be just one line but can also be a large area of color stripe. This is an error that you cannot fix yourself. If there is only one color line, we can temporarily accept and ignore it, but if the lines cause too many obstacles, you must fix it immediately.
- And the remaining error mentioned is also a common error on LCD screens, LCD screens with problems can be due to external impacts, or due to long-term use causing internal circuit breakage, circuit errors with laptop screens. Normally, you can only ask experts to fix the above errors, but with computer screens that are too old, you can throw it away to replace it with a new one.

Dead pixels on the screen are very annoying because they not only appear on old screens but can also happen on new screens. Simply put, this is an error that causes 1 or a few points on your screen to not display color regardless of what wallpaper the screen is using. The reason is that the pixels inside the panel are completely dead and cannot light up again when electricity passes through. There is no way to fix it, but we can check for dead pixels on the computer screen thanks to diagnostic and color display software. Refer to the instructions on how to check the computer screen to see if the screen has any dead pixels. If there are few, it is not a problem, but if there are too many, you should replace the screen with a new one.
4. Screen error with cracks
With cracks appearing on the screen, there is only one cause: the user. Using the laptop improperly causes the laptop to be impacted or not have protective devices such as shockproof bags. The same goes for the computer screen when we move it to a new location and let it hit something. With errors caused by impact causing damage to the screen and to fix this common error on the LCD screen, replacement is the only option you can do.
5. Screen error making noise
The screen makes noise when you start the machine, it is likely that the power port is damp due to a period of disuse or in an environment that is too humid. This is not a major error, but you should not be subjective and should fix it to avoid causing danger to the user. Take it to a professional repairman for early repair.
6. Incorrect screen resolution error

There are several reasons why the screen automatically turns off without a specific time while in use, and the main reason is a screen error. Because the screen has been used for a long time , some internal components may not operate properly and may be faulty.
Another cause is a problem with the display cable , it could be loose or it could be poor contact.
If it's the cable, the repair is simple, but if it's the screen, you have to take it out for more specific inspection and repair.
With the 7 errors above, you can easily identify the cause of the problem on your computer screen. On laptops, errors such as horizontal and vertical stripes on the screen can be annoying and affect your work. If you encounter this situation, you should repair it early to avoid further damage. In addition, to protect the screen, use a shockproof bag or backpack with a separate compartment for the laptop. This helps limit errors such as stripes, smudges or cracks on the screen due to external forces.
