Question 15 about the discoloration of the monitor

1 may be suddenly subject to electromagnetic interference, there is no problem, if it occurs frequently, pay attention to what interference sources are around, such as putting a mobile phone or something.

2 The display may be wet, or the screen may be static or magnetic due to continuous use for too long.

3 aging 4 hehe,The general color change of the display is the problem of the filter on the connection line between the display and the host (that is, the thicker cylinder at the line interface),When the problem first appears, it will change color when it encounters,And then it is often discolored,But it's good to touch the filter,It's not good to continue,It's best to change the line in advance,It's not expensive,Generally about 10 yuan is OK。

All of the above is possible

There are generally several situations of display color change:First, the display is magnetized,The phenomenon is local color change,For example, there is a speaker next to it or the speaker is too close,In this case, as long as the speaker is moved away a little, it's OK。 The second is that there is a problem with the circuit,This phenomenon is weak color,The third color is the change of contrast of the display,The phenomenon is that the color fades,The picture is blurry,In this case, you can adjust the contrast or press the recall key (some monitors want two keys on the panel to press at the same time is recall, that is, restore factory settings or press the recall key on the menu).

Fourth, the visual amplifier part of the display has poor contact and needs to be disassembled for maintenance.

Faulty display.

1.The display is wet.

2.Display aging (reverse repair).

3.Oxidation of signal terminals.

4.Problems with the graphics card.

5.If it is liquid crystal, the resolution is not on the optimal resolution (17 is 1280 1024).

With the display degaussing, it will definitely change back, but it will change after a while, maybe there is something magnetic next to the graphics card, or the graphics card is aging, replace one.

Because according to the principle of optics, any color can be mixed with three colors: R (red), G (green), and B (blue) through a certain intensity ratio. These three colors are called triprimary colors.

And the display works according to this principle, the display is used R channel, G channel, B channel to control the color display, and once there is a channel problem, it will lead to the lack of a primary color no matter what color and produce color changes, because we are in the computer, most places are bright colors, that is, it is closer to white, for example, when you open the browser, the background color of the web page is mostly white, take white as an example:

Because white is a mixture of R, G, and B primary colors at the highest intensity, and the computer uses numerical values as (255,255,255), at this time, if there is a problem with one of the color channels, it will cause the change of the primary color to be missing, or weakened, for example.

If the blue channel is broken, that is, it becomes (255,255,0), the white will become yellow, and the whole screen will appear yellow.

If there is a problem with the green channel, i.e. (255,0,255), the white becomes purple and the screen appears purple.

If there is a problem with the red, it will appear sky blue.

If there is a problem with both, such as red and green, the screen will appear blue.

However, the general channel problem is caused by the poor contact of a certain part, virtual welding, which is why sometimes you use your hand to pat it and it will get better, because the vibration generated by the slapping will make those parts that are not in good contact again.

Some monitor discoloration occurs after being turned on for a while, then comes back after a while, and then changes ,...... after a whileThis situation is because of the poor contact, the resistance at the contact point increases, a lot of heat will be generated, and the contact point of the part will be completely separated due to thermal expansion and cold contraction, resulting in circuit breaking, so that the channel stops working, causing the screen to change color: then because the contact point is separated, no heat is generated, the contact point begins to cool, and the contact point of the part will heal the contact point again due to thermal expansion and cold contraction, the channel will start to work again, the screen will return to normal, and then ...... againAnd so on.

If there is a discoloration of the display,Generally shake a few times will recover,If you're lucky,Will shake the place of the virtual soldering to the right position,And then there will be no discoloration for a long time,That's how my monitor is,Good luck last time,It hasn't changed color until now,It's just that I don't dare to touch the monitor anymore.,Wait for a touch and then there will be a problem pulling。

But I still recommend taking it to a repair shop to repair it,Generally, those who repair TVs will repair it,If you're a CRT monitor,If it's LCD,Then you have to take it to a place that specializes in repairing monitors。

The computer will encounter some problems after using it for a period of time, among which the problem of the monitor is the most common, which does not say that the computer monitor has been discolored, and the eyes of the computer are very uncomfortable for a long time, and there are many reasons for the abnormal color of the display, such as the graphics card driver is abnormal, the ** line is not plugged in, and there is a strong magnetic field interference outside. Whatever the cause, let's take a look at the solutions below.

Solution 2: Eliminate external interference.

Move electrical devices such as speakers away from the monitor to see if the colors return to normal.

Solution 3: Change the driver of the graphics card.

1、Uninstall win10The original graphics card driver is estimated to disappear after uninstalling the driver,If it is caused by the driver;

2. Then use the driver wizard or driver master to reinstall the graphics card driver, if there is a red screen after installation, you should try a few more driver versions, according to the case win10 under the intel core display caused by a lot of red screens.

Solution 4: Reinstall the monitor.

The monitor is the monitor.,It's also a slippery driver.,But it's the default driver of Windows.。

1. Check the click monitor in the device manager to see if there is a small exclamation mark, yellow.

2. Double-click the monitor, and in the driver interface, click Uninstall;

3. Restart the win10 system after uninstalling to solve the problem;

Solution 5: Color calibration.

Desktop right-click - Display Settings - Current Dialog - Advanced Settings - Below Resolution - Color Calibration.

The five solutions to the computer monitor that has been discolored are shared here, if the above Lu Youfa can not solve the mess, it may be hardware damage, graphics card damage and display damage can cause this problem, it is recommended to send it to the repair point for repair.

If the color of your computer monitor is not normal, it may be due to one of the following reasons:

Problems with display settings: Sometimes, your monitor's brightness, contrast, and color settings may be incorrect, resulting in distorted colors. You can try adjusting these settings in the Monitor Menu.

Graphics driver issues: Graphics drivers may need to be updated to ensure they are compatible with the operating system and provide optimal performance. You can try and install the latest graphics drivers.

Cable connection issues: The cable interface may be loose or damaged, resulting in interrupted or distorted signal transmission. The only thing we do is check the cable connections to make sure they are tight and undamaged.

If the above methods don't solve the problem, you may need to consider replacing your monitor or contacting after-sales service.

What kind of display are you using, is it CRT or LCD, if it is CRT, it may be magnetized, degaussing is OK,

CRT, right? There is a circuit board on the back seat of the picture tube with virtual soldering.

I don't know if you're talking about CRT or LED, but it's not the same.

The discoloration of the monitor is because your connection is broken, sometimes touch it, and the color is normal, right? You can just change one. Don't pull it on and off too often.

CRT or LCD?

If the graphics card is fine, then go and fix the VGA cable, right?
