Occasional bright lines on your laptop s screen?

There are lines on the screen, first determine whether it is on or after entering the system.

Lines appear when the computer is turned on, and the faulty parts may be screen cables, screens, and graphics card hardware problems.

After entering the system, it is recommended to reinstall the graphics card driver or restore the operating system.

The detection method is as follows:

1. Test the external monitor to see if the external monitor has a similar situation, so as to determine whether the fault is caused by the host part or the screen part.

2. The external display is normal, and the basic judgment is that the display is faulty.

3. If there is a similar fault in the external display, you need to consider updating the graphics card driver, flash plug-in or restoring the system.

Occasional bright lines appear on the laptop screen, which can be ruled out according to the following conditions.

You can use the external monitor of the notebook to troubleshoot the fault of the notebook display, if the external monitor display is normal, there is no appearance, and the line is bright, then you can eliminate the notebook graphics card, the fault.

Second, enter the PE system interface with the help of the USB flash drive PE system to see if the display is normal and whether there is a bright line? Troubleshoot graphics card driver and system faults.

Third, turn off the laptop screen several times, and then close the laptop screen and turn it on again, which is used to troubleshoot whether the laptop cable is faulty? Caused by the screen bright line issue.

Here's how to fix it:

I.1Go to the resolution settings of the computer screen and adjust the resolution to the highest (recommended) value.

2.After setting, remember to click OK at the bottom to save, and finally you will be prompted whether to save the display settings, click "Save Changes".

II.1If the external monitor works normally after being connected, then the display is damaged and sent for repair.

2.If the external display is also like that, it is a problem with the graphics card chip, replace the graphics card chip.

If it hasn't been out of warranty, hurry up and find after-sales service, if it's out of warranty, then wait for it to be serious and then send it for repair.

Is your problem solved and how was it solved.

Hello friends! This phenomenon of yours is that the LCD film in the laptop screen is a little degummed, my desktop monitor is also this phenomenon, I have been using it now, although there are some unpleasantness, but I also went to ask, it costs more than 500 to change a piece, who can guarantee that it is not removed from other computers, more than 800 for a brand new one, it is better to buy a new one, or will use it, it really can't be used, let's buy a brand new, so be it!

Hello: This is the LCD screen is broken, you need to contact the notebook for warranty, please deal with it as soon as possible, beyond the warranty period, the cost of repairing the LCD screen is very expensive. Thank you!

[Problem description]:

After entering the system, the desktop is displayed, and the screen color is not displayed properly.

Cause Analysis]:

Abnormal screen color display may be caused by graphics card drivers, monitors, etc.

Easy Steps]:

Set [Color Quality] - [Highest (32-bit)] - 360 Software Manager] - [Drive Life] - Reinstall [Graphics Card Driver] - [BIOS Settings] Check - Overhaul [Monitor].

Solution]:

Option 1: Set the color quality.

Figure 12Bring up the display [Properties] - [Settings], check the [Color Quality] option, normally there should be [Highest (32 bits)], Medium (16 bits)], if the color setting is lower than [16 bits], the color display is not normal, set to [Maximum 32 bits] to confirm. (Figure 2).

Figure 2: Option 2: Reinstall the graphics card driver.

If there is no problem with the [Color Quality] setting in the display settings, you need to uninstall the [Graphics Driver], restart the computer, and then install the [Graphics Driver], and be sure to restart the computer after the installation is completed;

Figure 43Run [Drive Life], select [Recommended Driver], find [Graphics Card] in the list below, type the box in front of [ ], and then click [One-click Update]. (Figure 5).

Figure 6 Scheme 3: If the reinstallation of the [graphics card driver] is invalid, then restart the computer and press the [del] (notebook generally F2 or F10) key during the self-test, enter the BIOS to observe, the BIOS interface is white on a blue background by default, if the color display is abnormal, you can bring up the [OSD] menu on the monitor panel, restore the factory default settings of the monitor, and replug the monitor [signal cable].

Solution 4: If the above operations are invalid, it may be that there is a problem with the [monitor], and you can contact the customer service of the display manufacturer for repair.

Driver issues.

This is also an important reason for the blurred screen, which mostly occurs after changing the driver version of the graphics card, and may also be caused by the corruption of the driver file. The solution is very simple, reinstall the driver that has passed the Microsoft WHQL certification, and the version does not have to be blindly updated. The first thing to check when the screen is blurred is the graphics card driver, which conforms to the principle of soft first and then hard.

Temperature issues. This problem is not only because of the graphics card, processor, memory and even the chipset of the motherboard is too high to cause a flower screen, such a situation mostly occurs in summer, but in winter, if the radiator falls off, the fan stops, it is also very likely that the temperature of the hard disk will be too high indoors, the same can not be ignored, it is recommended to open the case to check the installation of each radiator, try to open the case to run the game, to see if it will be a screen again, if the fault disappears or the time is delayed, it can be basically determined that it is a temperature problem.

Power supply issues. Including the power supply and the motherboard's ACP PCI-E 16X power supply, if the graphics card does not get enough and pure current, there is also a possibility of a blurred screen. The solution is to disconnect non-essential hardware such as optical drives and independent sound cards, reduce the load on the whole machine, and try again. Fourth, there are many reasons for graphics card problems.

It is possible that the BIOS of the graphics card is defective, and this can be solved by flashing the VGA BIOS; It is also possible that the video memory is damaged, which is a relatively common situation, and there is no solution for individuals, in addition, if it is a blurred screen caused by core damage, the graphics card can basically only be scrapped; It may be that the gold finger is oxidized or too much dust, which is the luckiest, as long as it is cleaned up, the oxidized part can be wiped with an eraser, and then washed with anhydrous alcohol, and the fault will disappear; There is also a problem that cannot be ignored is the capacitance on the graphics card, many graphics card screen is spent because of the capacitor, and some manufacturers even fell out of it (the famous king of the screen Gengsheng), in recent years, the emerging graphics card manufacturers have also adopted some very temperature-sensitive capacitors because of cost savings, as soon as the temperature drops in winter, the screen will be spent, and the fault will be eliminated after replacing the capacitor in theory, but it is recommended to contact the dealer for replacement or return to the factory for maintenance.

Problems with memory modules.

If it is not caused by the above reasons, you can consider whether it is caused by the damage of the memory module, you can remove the dust on the memory module by wiping, and then turn on the computer to see if the problem of the screen is solved.

Data cable issues.

If you are using a desktop, then if there is a blurred screen, then the first thing that should be ruled out is the problem of the data cable connected to the monitor and the host, it may be a loose connection, or it may be a lack of power supply caused by the oxidation of the connector. If reconnecting still doesn't solve the problem, then change the data cable, and if it doesn't work, then consider what other reasons are. (I've encountered it myself, so it's good to pick it up again.......)）

The common causes of screen failures such as screen flickering and screen shaking are: first, the quality of the screen itself, screen aging or inferior products, second, the screen line contact will not be damaged or damaged, and third, the motherboard screen power supply is abnormal or the screen failure caused by the virtual soldering of the graphics card BGA packaging chip, it is recommended that you send it for repair and testing.

During the warranty period, it will be sent to customer service for maintenance, free of charge (except for man-made damage).

Solution 1: The graphics card is faulty.

If there is such a situation, you should turn off the computer in time to let the computer rest for a while, so that the graphics card of your laptop will be buffered slowly, otherwise the graphics card will be damaged after long-term use.

In addition, the screen of the laptop should be wiped frequently, so as to ensure the cleanliness of the laptop screen, because once the inside of the screen enters the dust, it will damage the chip of the laptop screen, which is relatively fragile and cannot be restored once damaged, so it is very important to keep the laptop screen clean.

Solution 2: The display settings are abnormal.

If the refresh rate is set too low, it will cause the screen to shake, the check method is to right-click the blank area of the system desktop, and click the "Properties" command from the pop-up right-click menu to enter the property setting window of the monitor. Click the "Settings" tab in this window, and click the "Advanced" button in the corresponding label page that pops up behind it to open the advanced property settings interface of the monitor.

Then click on the Monitor tab and you can see that the monitor's refresh rate is set to 60, which is what is causing the monitor's screen to shake constantly. Set the new frequency to 75 or more, then click OK to return to the desktop, restart the laptop system, and then observe whether the laptop screen will still appear stripes, if it can be displayed normally, it means that the fault has been cleared.

Hello, in this case, it is recommended that you boot into the BIOS, and check whether there is also this line under the BIOS.

If there is, it is generally a broken screen, if not, it is a driver problem under the operating system.

Like my laptop, I started with a thin white thread that became two after a few days. You take a screenshot with QQ to see if there is a problem with the graphics card and cable in the screenshot, if not, it is a broken screen. Generally speaking, wired is a display screen with a long service life and virtual soldering.

I went to the maintenance office and said that it couldn't be repaired,In fact, there are some powerful masters who repair TV picture tubes can fix mine is to find a master who repairs TVs to get it!

It's always been there, and it's gone after a while.

This is a problem with the display screen, resulting in a line screen, the line screen is a line on the screen, there are horizontal lines and vertical lines, the color is generally white, yellow, red, blue, green, the width of the line is generally one pixel to three or four acorns, there are half lines and whole lines. This line will not have any effect on the functionality of the display, only the aesthetics and visuals. It is also irreparable, and it is a defective product in the factory that is treated as a price reduction.

In the production process of LCD screen, once it is detected that it is defective, it will be irreparable, and it will either be sold at a reduced price or disposed of as garbage.
