What will everyone do if they buy a new notebook but find that there are bad spots?

There's no way, as long as it's okay at 3 or less, this seems to be the rule in the industry. I also have one.,I found out when I tested the machine.,I was also very sad at the time.,Why was it so unlucky.,It was really super depressed at the time.,Super affect the mood.,It's all gone to my good mood when I buy a notebook.。 I couldn't do anything after negotiating for a long time, and in the end it was like this, no way.

As a result, there was nothing to do when I came back, and it didn't affect the use at all. It was very depressing at first, but after two days, it will be fine, and now it has no impact at all. Good luck!

Let time smooth out your grief

Excuse me.. I guess you can't change it. It should be that the merchant will tell you that it is normal to be within three dead pixels. You can go and ask.

If your computer has black dots on a white screen, the manufacturer will replace it for you.

If your computer has white dots when the screen is black, more than 3, the manufacturer can also replace it for you. If there are less than 3, it cannot be returned, but there is a problem with the display effect, which does not affect the use, and there is one PSP I bought, and it will not be replaced.

Lenovo's must be 3 to change, but ASUS is to ensure that you don't have one, so the display of i ASUS is better.

I read an article that says that the state stipulates that a screen cannot have more than 6 bad points, so your broken point is normal.

What brand, generally big brands can be changed.

1. Use the system to switch on and off interface interaction to test, the LCD screen is normal, sometimes the dead pixels are not easy to find, and the dead pixels cannot be repaired, the purchase finds that there are dead pixels, you can replace them in time, we found the dead pixels, you can find a bright spot from the interface interaction of the computer boot process, you can immediately know that there is a problem with the screen.

2. Use the system's built-in debug function to test, steps: win+r run box input cmd, enter debug, there will be multiple question marks, enter the following: fb800:

00f9f2070 carriage return turns white; fb800:00F9F2040 Enter turns red; FB800:00F9F2020 carriage return turns green; fb800:

00f9f2070 carriage return turns blue; In this way, you can identify whether there are bright spots on the screen.

3. Using screen contrast and brightness viewing, laptops can adjust screen brightness and contrast, we can adjust the brightness and contrast to the minimum and maximum when purchasing, and carefully observe whether the screen has dark spots or bright spots, so that you can also clearly know the number of dead pixels. If the quantity is large, it is recommended not to purchase it. Because the dead pixels cannot be repaired, they will only get worse and worse, and in the end, the screen will be replaced directly, and the gains outweigh the losses.

4. With the help of screen-related tools, there are also some LED test tools that specialize in Huye, which can directly run the test. This is relatively simple and convenient, and you may wish to ** the tool when you buy it, and test it on site.

5. The notebook display screen lasts for the longest time, its quality needs more attention, the notebook display usually avoids touching sharp things, or pressing directly with your fingers, the LCD will have bad pixels for a long time, and the bad pixels cannot be repaired, we encounter a lot of screen situations, sometimes because the graphics card is not installed well, but more is the screen is bad and directly change the screen.

6. Screen dead pixel detection is the main criterion for buying a laptop. Therefore, when purchasing, test more and observe more to avoid buying a substandard product and returning to the factory for repair, wasting time and resources.

It is unlikely that a bad pixel will be replaced.

And after the notebook is bought, if it is not used properly, it will also cause the LCD screen to produce dead pixels. Turning on the machine for a long time or displaying the same picture for a long time is easy to accelerate the aging of the LCD screen and promote the formation of dead pixels.

If you find dirt on the surface of the LCD, you should use the correct method to remove it. The medium used is preferably a soft, non-fibrous material, such as absorbent cotton, lens paper or glasses cloth, etc., which can be cleaned with water under normal circumstances; When wiping with water, wring the cloth out as much as possible. However, if the cleaning effect cannot be effectively achieved, you can consider purchasing the current liquid crystal cleaning products on the market.

In particular, experts point out that consumers should not use cleaning solutions containing ammonia, alcohol and inorganic salts.

Yes, screen quality issues. Hurry up and find an after-sales exchange.

Depending on your situation, I think there are probably several possibilities:

First, it is possible that some of the two software installed in your computer may be conflicting, that is, incompatible, in this case, it is recommended that you reinstall the system, which should be solved.

The second is that there may be a problem with your power supply, some miscellaneous brands of small manufacturers of power supply may lead to insufficient power, so that your computer is overclocked, so there will be a blue screen, in this case, you have to take it back to the dealer to change the power supply and it will be fine.

The third is whether your memory has poor contact, it is recommended that you take off your memory, wipe it clean and rotten with a leather wipe or cloth, and then install it to see.

Fourth, it may be that the environment of the place where your computer works is not very good, so that there is too much dust on the CPU or graphics card fan, so that the fan heat is not good, in this case, you need to remove the dust on the fan and then turn it on.

The notebook's LCD screen consists of two glass plates, about 1 millimeter thick, with crystal droplets about 5 microns (1,1000 millimeters) thick in the middle, evenly spaced and contained in a small cell structure, each of which forms a pixel on the screen. Under a magnifying glass, it appears in a lattice shape, and a pixel is a point of light. Each spot has an independent transistor to control the intensity of its current, and if the transistor at that point is broken, it will cause the spot to be lit or not lit forever, which is the bright spot or dark spot mentioned earlier, collectively known as "bad spot".

The LCD screen of this book has a dead pixel, is it normal?

According to the default standards in the industry, "bad pixels" are a "normal" phenomenon, just not too much. A certain number of bright spots or dark spots in laptops is a characteristic of LCD technology, and such a phenomenon is inevitable for any manufacturer. Some manufacturers believe that the total number of dark spots and bright spots on the LCD screen exceeds 9, and some large-size computer screens even exceed 16 before they are identified as having problems.

Therefore, there has been a phenomenon that consumers have bought a computer and found that the bad pixel problem has occurred, and the manufacturer does not admit it at all, and almost all notebook dealers have encountered users who have asked for a replacement or replacement of the LCD screen.

How do manufacturers around the world measure the level of LCD displays based on the number of dead pixels? Let's take a look at a simple set of data comparing the Japanese standard: below 3 dead pixels are A-level pass; Korean Standards:

The following 5 bad pixels are A-level qualified Taiwan standards: 8 bad pixels below are A-level qualified Zhongke standards: 0 bad pixels below are AA-level qualified, and 3 bad pixels below are A-level qualified.

In Taiwan's review standards, an LCD screen with less than three (inclusive) is considered qualified; However, Japan is only qualified if it is within one (inclusive).

Only ASUS notebooks are guaranteed to have no bright spots, HP is not guaranteed, as long as it is normal within three, so you use it like this, in fact, one is nothing, I am a monopoly HP, the quality is good!

There is a problem with the laptop screen, it is recommended to send it to the repair station to check that there is a problem with the high-voltage plate.

1 Failing to protect your computer.

2 There is a problem with the computer in the first place.

3 The plug is not plugged in properly.

2.Use a key repair tool: Some computers are equipped with a key repair tool that can fix dead pixels by pressing a specific combination of keys. For specific operation methods, please refer to the user manual or official ** of Senxu computer.

3.Use Dead Pixel Repair Software: There are specialized software that can help fix dead pixels. You can search for and ** these software on the internet and follow the instructions for using the software.

4.Tap the screen: Sometimes, dead pixels can be caused by dust or impurities on the screen. Try tapping the screen to remove these impurities, and sometimes the dead pixels will disappear.

5.Hardware replacement: If none of the above methods can fix the dead pixels, then the screen may need to be replaced. You can contact a professional computer Victor Repair Center or after-sales service center, they will help replace the screen and solve the problem.
