My computer often has a blurred screen, is there a problem with the wiring?

There are three problems: graphics card, cable, system!

The reason for the blurred screen of the computer monitor is 1:

1. If the graphics card is in poor contact, pull out the graphics card and clean the gold finger.

Reinsert (Integrated Graphics.)

Skip). 2. Graphics card cable problem: Replug and unplug the cable to see if there is any change.

3. Graphics card driver.

Problem: Reinstall the graphics card driver.

4. The display screen is broken: replace the LCD screen of the display outside the warranty period or find the seller to pay for maintenance, and find a dealer for free repair during the warranty period;

The second reason for the blurred lines of the computer monitor:

1. Due to poor heat dissipation of the case, the screen caused by the temperature of the graphics card rises.

The solution is to eliminate heat dissipation issues.

2. The solution caused by the graphics card or monitor does not support high resolution:

1) Restart the computer, press the F8 key continuously, pop up the advanced boot menu, select enter to enter the "Safe Mode" to log in to the system, then enter the display settings under Windows, select the 16-color state, click the "Apply" button, and click the "OK" button.

2) Restart your computer, and in Windows normal mode, go to Device Manager.

Remove the graphics driver.

Just restart your computer.

3) The graphics card is loose, and after shutting down, unplug the graphics card and re-install it, usually Sun Xiao's pretending can solve the problem.

4) System overheating, including CPU temperature.

If the temperature is too high, the temperature of the graphics card chip is too high. You can install cooling fans in the appropriate locations in the case, or place the case in a well-ventilated area.

The computer monitor has three reasons for the blurred screen

1. Lack of plugins. InstallFlashPlayer (required online**) and K-lite Codec Pack (hard cooktop**required),**Installation can generally be solved.

2. If the graphics card driver is wrong, reinstall the original driver, or you can use the driver to automatically fix it.

However, after reinstalling, playing games still continues to blur the screen, and most computer monitors have blurred screens due to the installation of incompatible graphics card drivers.

Or a small part of the graphics card temperature is too high caused by hardware aging, etc., and the lower travel slip grip will introduce you to a few simple methods.

The first case: the display water ripples flickering.

The main reason for the flickering of water ripples in the display is the cable, which can also be said to be one of the common problems. Generally, there are three types of cables used by the host to connect to the display: VGA cable.

DVI cable, HDMI cable.

In addition, there are uncommon DP lines. In addition to the DP line, which is quite expensive, the other three wires are relatively cheap, and the quality of most of the wires is also faultless. But if you still have a good chance of catching up with inferior wires.

The second case: the display screen is blurred and the screen is black.

The host has been running, there is no fault with other devices, the display has been powered on, and the power indicator indicates standby, but the display just doesn't light up. If your monitor is black and the power light isn't on, check that the power cord is plugged in. If the power supply is plugged in, replace the power cord.

If you can't change the power cord, then your monitor must be a hardware problem.

The third case: colored lines appear on the display.

In fact, to deal with this failure, we must first know that there are two main reasons for the appearance of colored lines: first, if it is a full screen of colored lines, or with the transformation of the display content, usually their position is not fixed, generally does not fill the entire screen, most of this situation is caused by graphics card failure, such as video memory.

Overheating or drivers.

Mistake. The general solution is to reinstall and set the graphics card driver, and if the graphics card is overclocked, please also reduce it back to the rated power handicap.

Clean the fan or heatsink at the same time.

and enhance chassis heat dissipation.

Secondly, if it is one or more lines covering the entire screen, even if the content of the display changes, the position and color of the lines do not change, and most of the reasons are that the control chip or cable of the LCD screen is faulty, and such a fault can usually only be sent to the manufacturer for maintenance.

Fourth case: There are two vertical black bands on the edges of the display.

This phenomenon mostly occurs on older computers, which is caused by the lack of video memory on the graphics card. Older computer graphics cards had only 1 MB of video memory, which can occur if the resolution is set too high. To deal with this failure, you can add video memory to the graphics card, and there is usually a socket for adding video memory on this type of graphics card.

The fifth case: the display screen is shaky.

The graphics are shaking so badly that sometimes you can't even read the icons and text, but after a minute or two, it will return to normal. This phenomenon mostly occurs in wet weather, which is caused by moisture inside the display. To deal with this problem thoroughly, use the moisture-proof sand from the food packaging to string it with cotton thread, then run the back cover of the monitor and hang the moisture-proof sand near the end of the CRT neck near the head.

In this way, even in wet weather, the above-mentioned "problems" will not occur again.

Generally, there are three situations.

1.The graphics card is in poor contact with the display signal cable, and it can be installed before retalking.

2.The monitor itself contains a fault, and this needs to be replaced.

The solution caused by the graphics card or monitor not supporting high resolution:

1) Restart the computer, press the F8 key continuously, pop up the advanced boot menu, select enter to enter the "Safe Mode" to log in to the system, then enter the display settings under Windows, select the 16-color state, click the "Apply" button, click the "Zhengyou OK" button;

2) Restart the computer, check the banquet in Windows normal mode, enter the device manager, delete the graphics card driver, and restart the computer;

3) The graphics card is loose, and after shutting down, unplugging the graphics card and reinstalling it can usually solve the problem;

4) If the system is overheating, including the CPU temperature is too high and the graphics card chip temperature is too high, you can install a cooling fan at the corresponding position in the case, or put the case in a well-ventilated area.

That means your monitor is broken, what else can you do? You can only repair it, or buy a new one directly.

The computer display is only connected to the power cord, but the display screen is blurred.

Kiss; The first situation: display water ripple flickering The main reason for the display water ripple flickering is caused by wire, which can also be said to be one of the common problems. There are three common types of cables that are generally used by the host to connect to the monitor:

VGA cable, DVI cable, HDMI cable, and other uncommon DP cables. In addition to the DP line, which is quite expensive, the other three wires are relatively cheap, and most of the wire quality leakage is also faultless. But if you still have a good chance of catching up with inferior wires.

The second case: the display screen is blank The host has been running, and the other equipment has not failed, and the display has also been powered on, and the power indicator liquid light indicates standby, but the display.

Many people encounter the LCD screen cable and the LCD screen poor contact resulting in the LCD display.

Flower screen,Very annoyed,I don't know what to do,The following is the information I have compiled for you about the laptop monitor flower screen line,I hope it will help you!

The solution to the blurred lines of the laptop monitorWhen encountering poor contact between the LCD screen cable and the LCD screen, the LCD display is blurred, and the first thing that comes to mind is to replace the screen cable.

First of all, we broke down the motherboard and can be seen obviously, and the most important thing is to know Hitachi.

HDD and Western Digital.

The Seagate hard drive is different in the circuit board, the disc body contact points. Hitachi contacts are tinned so that there is no oxidation. According to the empirical analysis, the original oxidized screen wire can be cleaned and then plated with a thin layer of tin, as shown in the figure.

<> first, clean the contact surface that has been oxidized;

Second, the first tin is plated, and the soldering iron must be mastered when plating.

The temperature should not be too low, or it will burn the insulator next to it.

Third, the effect of washing with a special cleaning solution;

Fourth, after cleaning, paste the front and back with paper tape;

<> fifth and final step Insert carefully, and with tin foil.

Paste firmly, and ensure that there will be no more blurred screens;

The notebook suddenly blurred the screen,Shaking energy recovery,The biggest two possibilities are cable problems and graphics card virtual soldering,If the repair point has been confirmed to be a wire problem,And you don't want to repair it at the maintenance point,You can have the following two options:

1.Disassemble the computer yourself and bet on the problem of poor wire contact,I have encountered the flower screen caused by poor wire contact,This is OK as long as you press the interface at both ends of the wire,I hope your problem is this problem。

2.If the cable is broken, you can search for the cable of this series of computers on TB, and buy it, this ** definitely not 380, some even only a few dozen, of course, it depends on different machines.

3.Finally, whether you can repair the computer city depends on whether you are a big city or a small city of the computer city, if the computer city like ours belongs to the computer city of the second and third tier cities, then they can rarely repair the screen cable manually, they also have to go to other places to buy, and then give you a change, but if you buy it, it is better for you to go to TB to buy. If it's a computer city in a big city, they have the ability to weld the screen cable, or even re-change the screen line for you.

The last problem, as long as you confirm that it is the maintenance point designated by Dell, it can be solved within a week, and they will record the SN code of each of your accessories when repairing, and they will not replace it for you. You can rest assured of this.

Hope it helps!

The problem with the screen itself may be larger,The screen line is generally more than a hundred enough,But there is no way,Yours is still under warranty,This after-sales service is a franchised maintenance station,Even if the screen problem is generally pushed to the non-warranty device,This can make more money。 The conclusion of the screen line problem given by this after-sales service has no reference value, and the questions of the notebook can be helped.

This should be a matter of wiring.

Computer City can be repaired. But if you want to guarantee it later, there is no way. Because after dismantling, it cannot be guaranteed.

The reasons for the sudden blurred screen of the notebook are divided into the following:

First, the problem of the graphics card is generally that the graphics memory is defective or soldered.

2. The cable is broken or the interface is in poor contact.

Third, the display screen is broken internally.

Differentiation method: connect an external monitor, if the external display is normal, it is the display, otherwise the display card is bad or the cable is bad (the probability is low).

Let's go to a special maintenance company to change the cable. Dell's contracted repairers won't dismantle your stuff.
