What s going on with the display color turning green

Replace the graphics card. Reason:

1. The graphics card is broken.

3. Poisoned.

A display is also commonly referred to as a monitor. A monitor is an IO device that belongs to a computer, i.e., an input and output device. It is a display tool that displays a certain electronic file on the screen through a specific transmission device and then reflects it to the human eye.

According to the different manufacturing materials, it can be divided into: cathode ray tube display (CRT), plasma display PDP, liquid crystal display LCD and so on.

There is no unified concept of the display, but the understanding of it is mostly the same, as the name suggests it should be a certain electron.

A display in which a file is displayed on a screen through a specific transfer device and then reflected to the human eye.

Tool. From the early black and white world to the color world, the display has gone through a long and arduous process, with the continuous development of display technology, the classification of the display is becoming more and more detailed, LED

There are more than 500 display factories mainly distributed in Shenzhen, of which 40% are mainly providing processing services, as well as small workshop production, and there are also a number of production based on quality and research and development.

Enterprise. It is often said that the three elements of a computer that directly affect human health are:

Keyboard, mouse, monitor. The traditional slotted keyboard requires both hands to be placed in the middle of the letters when used, so the user has to tighten the shoulders and cantilevered the arms, which is easy to fatigue and cause injury to long-term use.

Merchants have seen this and have successively launched various ergonomics.

Keyboard with. Mouse, extremely popular.

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

2. The external display is normal, please re-plug and unplug the screen cable interfaces on both sides and fix and check whether the cable routing at the screen axis may be squeezed and interfered with by other components.

3. The above operation is invalid, replace the LCD screen test, if the fault disappears, it is the LCD screen failure, and the fault still exists basically because of the screen line problem.

4. 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.

5. Software problems cannot be troubleshooting, replace the CPU test, to determine whether the fault is caused by the CPU or the motherboard.

There are times when our computer monitor screen turns green, what should we do? Let me briefly introduce you to the solution to the green screen of your computer monitor! Hope you enjoy it!

Analysis of the causes and solutions of the green screen of the computer monitor:

The computer screen is green, which can be solved by the following aspects:

1) The connection signal line between the graphics card and the monitor is not in good contact. You can replug the VGA connector when the power is off, and carefully check whether the pins are bent or deformed, and whether the signal cable is broken.

2) If only a certain part of the screen, especially the four corners of the screen, there is a color cast, generally due to strong magnetism.

field interference. At this time, you can check whether there are strong magnetic devices around the display, such as speakers, high-power power transformers, etc., and try to move these devices away.

3) Some monitors have a color temperature setting function, if there is an error in the setting, it will also cause a color cast failure, but the actual performance of this color cast is that the whole screen is biased towards a background color. This problem can be solved by simply readjusting the color temperature parameters correctly.

If the color shift doesn't get any better no matter how much you adjust the color temperature parameter, the problem is the chroma inside the display.

The output transistor is "soft-broken", or biased potentiometer.

Poor contact. In this case, it is better to send the faulty display to a professional maintenance personnel for processing.

Secondly. Generally speaking, the display turning green may be due to the poor contact of the signal line and the failure of the display itself, which can be solved in this way:

1. Open your main case, find the graphics card, and then clean up the graphics card's "gold finger".

Wipe with an eraser and clean the dust from the graphics card slot with a brush;

2. Check the com port of your host to make sure the contact is good;

3. It is recommended to keep a long distance between the speaker and the monitor, if it is too close, the display will be slowly magnetized by the audio, if the display has the "demagnetization" function, press the menu button below the display, find the "demagnetization" and confirm, with the instantaneous shaking of the display, the color will be restored.

Solution: Additional computer monitor screen is green:

Mouse click on the desktop right-click, Properties.

Open the Show Properties Sacred Word box and select the "Appearance" option "Advanced".

Open the Advanced Appearance dialog box and select Colors > Other Colors for the Project edge

Open the Color dialog and put hue with saturation.

and brightness modified to 85, 90, 205, respectively. Once set, press "Add to Custom Color" and then "OK".

It could be because your graphics card isn't updated.

It's also possible that the link behind your monitor is loose.

It's also possible that there is a problem with your monitor

The first step is to update your graphics card drivers

Step 2: Check whether all the interfaces connected to the display are loose.

Power supply included. The third part, if the above 2 steps still do not survive. Just call ** to the manufacturer of the display for door-to-door maintenance ps: you can adjust the inside of the monitor.

Hue and saturation.

Display discoloration is generally due to poor contact of signal lines and failure of the display itself. You say that the boot is normal, half an hour later, and it is good after half an hour, then you can rule out the problem of the signal line, which is the problem of the display itself, and it is a hot place on the circuit board of the display, and the solder joints are loose and the contact is not good!! Due to the temperature rise half an hour after starting, the solder joint is heated and expands and deforms, resulting in the circuit being disconnected and the fault occurring.

After the cold is cold, the solder joint returns to normal and the circuit is turned on. So you said that slapping the monitor has the potential to bring it back. It is common sense that the phenomenon of "no work if you don't play" in general electrical appliances is because of poor contact.

Next, combined with the color cast phenomenon you mentioned, I think it is a problem with the opto-amplification circuit on the tail plate of your picture tube. Find a soldering iron and a magnifying glass, and carefully repair the suspicious area. In addition, it is doubtful that the signal cable is connected to the part of the display circuit board.

If not, check the main circuit board thoroughly.

First of all, replug and unplug the data cable of the monitor,Reconnect at both ends,See how,No,Press the del key when you turn it on,See if the color of the picture is normal,If you enter the computer system normally, the display is not normal, that's a software problem,The monitor is no problem,You can reinstall the system,Or uninstall the graphics card driver and reinstall,On the contrary, if the color of the picture is not normal after pressing del,That's a display problem,At this time, pay attention to the display in addition to the power button There will be other physical buttons, Use these physical buttons to bring up the monitor settings menu, select Factory Reset to see how it is, and if the problem is still very good, it is likely that there is a problem with the monitor.

If the contact between the monitor and the computer is not good, plug the cable between the monitor and the computer again. If that still doesn't work, try a different cable.

Because the three primary colors of the display are red, green, and blue. Usually because one of the cables (such as green) is not connected properly or broken, there will be a "color cast", also known as "lack of color". The phenomenon is exactly what you described.

You connect your monitor to another computer, and if it's still green, it's a problem with the monitor; If it's normal, it's a problem with the graphics card.,It's a problem with the display.,Adjust the chroma or something.,No, it's the hardware of the display that's broken.,It's a problem with the Ricka.,Reinstall the graphics card driver first.,If it doesn't work, reinstall the system again.,Or if it doesn't work, it's the graphics card hardware is broken.。

The display is composed of three colors, and if there is one less now, it will turn green, most of which is caused by poor contact of the connecting wire.

There are two possibilities for the display to turn green.

1. The reason why the display turns green:

1.The display is green, but you can see other colors and images clearly.

2.The display screen is all green, and no picture is displayed, which is caused by the damage of the green transistor or the aging of the picture tube.

Second, the solution to the display turning green:

1.Turn on the monitor and adjust the green amplification cut-off potentiometer.

2.You can use a multimeter to check, measure the voltage of the collector of the green transistor to the ground, which is generally very low, roughly below 20 volts, unplug the tube socket, and then measure the voltage of the collector of the green transistor to the ground, if it is almost the same as the previous measurement, the green transistor is damaged, if the voltage rises to about 180 volts, it is a picture tube failure.

The VGA cable is loose, tighten it a little.

Monitors? You turn down the three primary colors of the monitor and see if the color value of which primary color has changed.

Is your computer an assembly machine or a brand machine?

1. Open your main case, find the graphics card, and then clean the "gold finger" of the graphics card and wipe it with an eraser. And use a brush to clean the dust from the graphics card slot.

2. Check the com port of your host to make sure the contact is good;

3. The machine that has just been bought for half a year should not have major problems, and the display should not be broken. It is recommended that you keep your speaker and the monitor far away, otherwise the monitor will be slowly magnetized by the speaker. If your monitor has a "Degauss" function, press the Menu button below the monitor, find "Degauss" and make sure that the color will return as the monitor shakes instantaneously.

There are times when our monitors are on the green side, what should we do? Let me give you a brief introduction to the reasons and solutions for the green color of the display! Hope you enjoy it!

Reasons and solutions for the greenish color of the display:

Wiring issues: The cable between the monitor and the graphics card. All the color information on the graphics card is often passed to the monitor by a data cable, and if something goes wrong here, it will also cause the ternary color to be missing or the color is abnormal. So you can consider trying a different line.

Software Problem: The driver of the graphics card is not installed properly. In fact, even if there is no driver, the monitor will display each color correctly, so as not to lose the meta color, but if the driver is not installed correctly, this problem may occur.

For example, the type of the graphics card and the driver type are inconsistent, and the version is inconsistent. This problem is very simple to solve, just uninstall and reinstall the original graphics card driver.

The way to uninstall the driver is: My Computer - Right-click"attributes"-- Hardware -- Device Manager -- Graphics card -- Right click -- Uninstall. The way to detect if there is a problem with the graphics card driver is simple:

Taking Windows XP as an example, if the XP logo can be displayed correctly when the computer boots into the scrolling waiting screen, but the red logo on the XP logo cannot be displayed after entering the system, it is obvious that the card driver is incorrect.

Display issues:

Monitor hardware failure. There are many reasons for display hardware problems, such as aging of the picture tube, line oxidation caused by humidity in the environment, static electricity, etc., which will cause abnormal color display. Different methods can be taken according to different reasons, such as placing the monitor in a ventilated place, etc. (many people like to cover the display with a cloth to prevent dust, here is a reminder that dust should be covered with a special dust cover, otherwise it may lead to poor ventilation and heat dissipation of the display).

Graphics card issues: Display issues are the most frequent issues. For example, the card slot is not tightly contacted, the graphics card is overheated, and the graphics card wiring and components are problematic.

For the problem that the card slot is not tight, you can unplug it and reinsert it, sometimes it may be because there is more dust, here you need to clean the slot and clean the graphics card with a tool such as an eraser. For the overheating of the graphics card, you can install a small fan on it or place the chassis in a ventilated place, the color caused by the overheating of the graphics card is often more normal when it is first turned on, and it begins to change color after a period of use.

Workaround for the greenish color of the additional monitor:

Mouse click on the desktop right-click, Properties.

Open the Show Properties Sacred Word box and select the "Appearance" option "Advanced".

Open the Advanced Appearance dialog box and select Colors > Other Colors for the Project edge

Open the color dialog and change the hue and saturation and brightness to 85, 90, and 205, respectively. Once set, press "Add to Custom Color" and then "OK".

1.Check the updated drivers for your graphics card to make sure that the drivers for your graphics card are working properly... 2.

Check the connection between the monitor and the graphics card, clean up dust or oxidation... 3.Check whether the cable is broken, you can also replace the data cable, as well as the connection between the graphics card and the motherboard, and whether the fan on the graphics card is working properly

4.If that doesn't work, press the adjustment button on the monitor to restore the monitor to its factory settings 5.

Pre-emptive safe mode to determine whether there is a driver and system problem... 6.Connect the laptop to the monitor to determine whether there is a graphics card problem...

By the way, the temperature of the graphics card is detected
