My monitor is blurry like fog and uncomfortable to look at

General causes of display blur and treatment.

1. The blurred screen display is one of the common failures of various displays, and the main reasons for this are the following three aspects:

1. The focusing potentiometer of the FBT (line output transformer) is loosened or displaced due to vibration during transportation or use, which changes the focusing voltage added to the CRT (deviates from the optimal voltage value debugged by the factory), causing the screen to be blurred;

2. The humid environment around the monitor causes rust on the discharge ring (semi-sphere) of the focusing pin on the CRT tailstock board, and it is blurry when the CRT is just energized;

3. Due to the impurities in the manufacturing process or the glass shell of the CRT cone, electrostatic dust is generated between the focusing (focuse) pole and the acceleration pole (G2), which forms and resists and causes serious blurring of the screen.

2. Determine the cause according to the different situations caused by the phenomenon of blurred screen.

Judging by the program with a blurry screen:

1 If the blurring is mild, it is only the thickening of the glyph outline that still makes the character recognizable, which is mostly caused by the first cause.

2 If the CRT is blurry when it is first turned on, the characters on the screen become clearer and clearer as time goes on, which is usually caused by the second reason.

3 If the characters are heavily blurred over a large area, the screen is white and the characters are unrecognizable, and the brightness of the focusing potentiometer screen on the FBT is dimmed, it is the third reason.

3. Troubleshoot after judging the cause of the screen.

1 In the first case, open the lid and fine-tune the Focus potentiometer in the FBT to troubleshoot.

2. For the second case, for the treatment of the corrosion of the discharge ring of the focus pin on the tail plate, the discharge ring and the electrode plugs and sockets on the tailstock are generally cleaned with anhydrous alcohol, and the tailstock parts can be replaced when the discharge ring is seriously corroded.

3. For the third case, remove the CRT tailstock plate, lead the CRT high-voltage cap 24kV high-voltage multimeter pen line (it is best to use a digital multimeter with better insulation performance) into the CRT focus board socket, turn on the AC power supply of the display, and use the grounding meter pen wire to instantly discharge the accelerator pole (G2) plug 2-3 times (it is best to draw out the CRT upper (G2) plug with an additional protective sleeve**, and carry out the right instantaneous discharge operation on the lead wire). After 2-3 times of discharge process, the electrode-like resistance between the focusing (focuse) and acceleration electrode (G2) can be broken down, after restoring the original circuit, observe the screen characters and ** display clarity, if necessary, appropriately adjust the focus potentiometer on the FBT to make fuzzy troubleshooting.

On the desktop, right-click --Properties --Settings--Advanced--Monitor, turn up the refresh rate, and you're good to go.

If the warranty is over, open the back cover of the monitor, and you can see two potential regulators, one for brightness and one for focus. Just adjust the focus, turn on and adjust.

The focus of the monitor is not good, take it to the place where the TV is repaired, just go and fix it, pull it more than 20 fast, and it should be done.

Is the display aged to see its factory date.

1.First, adjust the focus knob of the upward output of the display movement board to see if there is any improvement.

2.There is no improvement in looking at whether the socket focus box of the monitor is dirty (wipe it clean with alcohol) and open soldering (soldering with an electric soldering iron).

3.If the above is not good, it means that the monitor itself is out of focus. There's only one way.

With electric shock (unplug the sight plate first, power off after the power has high voltage, use a wire, the high voltage of the high-voltage nozzle is drawn out, and one end is aimed at the focus pole of the display to discharge. Just play a few more times).

If it's not good, then it's completely useless.

If you have been using the monitor for a long time, it may be due to the humidity of the use environment and the aging of the internal electrical components, so you can place the monitor in a slightly dry place. If your monitor is powered on, this problem can be easily solved, but I personally think it is not very safe.

If it is a new display, it may be due to the lack of electromagnetic shielding inside the display, and the picture tube is affected by the earth's magnetic field to produce blurred, jitter, etc., it is recommended to change the direction of the display, preferably in the north-south direction.

It may also be caused by moisture, the picture tube of your monitor is aging, and it needs to be heated every time before it can return to normal, such a phenomenon, send it for repair, it can be improved within about 50 yuan, but, such a phenomenon cannot be completely changed. If you plan to replace the monitor for another six months and a year, you don't need to pay attention to this problem, but if the weather is too humid, the screen may flicker, and it is also because of the aging of the picture tube, so you don't have to be too nervous.

If there is a burst of sudden discoloration, it is caused by the poor contact of the signal line, if it is a long-term local display area discoloration, then, it is recommended that you change the direction of the display, it will be improved.

The display looks blurry and can be solved with the following solutions:

1. Update the graphics card driver (if the graphics card driver is not installed correctly, there will be a blurry problem);

2. Carefully check the interface between the monitor and the graphics card, and plug the monitor cable back in (loose display cable will also cause blurring);

3. Replace a monitor cable (if there is a problem with the monitor cable, it will cause blurring);

4. Adjust the display resolution (if the resolution is incorrect, the display will become blurry);

5. Replace a graphics card (problems with the graphics card will also cause the display to become blurry);

6. Reinstall a different version of the system (if there is a problem with the system itself, it will also cause the display to be blurry).

A common problem with displays.

1. You may wish to press the initialization button on the monitor first, let's look for it, generally the buttons on the computer screen, let's try it next to each other, when your monitor is similar to restart, then find the right one.

Resolution issues.

2. Click on the stretch bar of this screen resolution, try it next to each other, and choose the best one. For example, if I have a resolution of 1440*900, if I change it to another resolution, the icons will become wider or narrower.

3. Click "OK" after setting

31. Generally the above steps can solve the blur problem of the display, if it still doesn't work, simply change a monitor to see. If it's still blurry after changing it, it may be a problem with the host graphics card, and you can only go to a repair shop to take a look.

Counterfeit and shoddy wire is the source of the bane, and inferior wire is the bane: the following three types of cables are commonly used to connect the computer screen to the host, VGA cable, DVI cable, HDMI cable, and uncommon DP cable. In addition to the DP line, the other three kinds of wires are quite cheap, 5 pieces, 10 pieces of one, this price is a fair price, and the quality of most of the wires is no problem.

But if you occasionally click on the back, it is possible to catch up with the inferior wire. If the two methods mentioned above do not solve the problem after trying, you need to investigate whether there is a problem with your cable. The easiest solution is to change the cable to the computer screen.

Don't turn off the computer screen, the host graphics card malfunctioned: the computer screen appeared water ripples, and the author has seen it twice caused by problems with the host. The specific fault performance is that the same host, no matter what computer screen is replaced, will always have water ripples.

This problem can be said to be a hard injury, even if the host is sent for repair, most of it will not be solved. The easiest way to do this is to add a graphics card to the barebones system (if you can). After adding, it can solve the problem almost 100%.

Right-click on the desktop, and then click Advanced in the settings, there is a monitor in it, and set the monitor settings to the highest.

Cause: There is a problem with the resolution.

XP system needs to switch to the settings tab) Click Save, the screen will flash, and the time to witness the miracle has arrived - the screen is instantly clear! Don't forget, click again to save your changes. If you look at the effect of the change, the contrast is obvious.

Phenomenon: The characters on the screen are blurry when the device is first turned on, and everything works fine after a few minutes, and there is no such fault when the device is hot-started.

Reason 1: The monitor is blurry and can return to normal after a few minutes, which may be caused by moisture, dust contamination or poor quality of the socket at the end of the picture tube. If the condition is not severe, the problem can be eliminated by cleaning the CRT with alcohol.

In severe cases, it may be a problem with the tailstock of the picture tube, which is the same as the picture tube of the TV, which may be caused by the poor performance of the electrolytic capacitors of the related circuits, but it is very unlikely.

Reason 2: Blurry when powered on may also be the display "aging". The cathode ray tube inside the CRT must be heated by the filament before it can emit an electron beam, but if the cathode ray tube begins to age, this heating process will be slowed down.

At the beginning of turning on the monitor, the characters on the display will be blurred because there is not enough electron beam to bombard the phosphor screen because the cathode ray tube does not reach the standard temperature and cannot shoot enough electron beam. If your monitor has not been purchased for a long time, it is likely that the quality of the CRT is poor or shoddy, and you should ask the dealer to exchange it.

Solution: Windows+R run, then enter, enter, select the display card, select one, then disable it, wait for a few seconds and then enable it, and it will be restored.

It should be a problem with the graphics card. Re-drive once to see.

Or right--Properties--Settings in an empty space on the desktop. Then look at the screen resolution.

Generally 1024x768

There are two reasons why your computer suddenly becomes blurry

The first is because the resolution is not adjusted well, and the solution is as follows:

1. Right-click on the screen resolution option on your desktop.

2 Click on the option of Resolution (R) to adjust the resolution size and adjust the corresponding screen and font.

The second is because the card driver is damaged or the graphics card driver is not installed, and the graphics card driver can be reinstalled.

Installation of the driver.

Method. 1. Install directly by finding the corresponding driver file:

1. Right-click "My Computer" and select "Manage" from the pop-up menu.

2. In the "Computer Management" window that opens, click "Device Manager", then right-click on the name of the driver that has not been installed normally (that is, there is a yellow exclamation mark), and select the "Update Driver" item.

3. In the "Install Driver Wizard" window that opens, select "Install from List or Specified Location" and click "Next", then specify the location where the driver is stored, and click "Next" to automatically update the hardware driver.

Method. Second, the software is used to automatically find and match the driver for updating.

1. The corresponding driver management software can be used to realize the automatic installation of the hardware driver.

3. When running the software, it will automatically scan all the hardware of the current computer and determine the model of the hardware and the installation of the driver.

4. In the main interface that opens, click "Driver" and "Automatic Update" tab, then check the hardware list items where the driver is not installed correctly, and finally click the "Update Now" button to update the operation.

It gets better after a while! Some monitors need to be warmed up.

Click on the display to adjust the menu, select the flexible viewing angle in the image options, if it is the angle of view 1 in the blurred case, you will choose the angle of view 2, and vice versa, select the angle of view 1

Me too, I'll be fine in a while.

After working for a while, take a break to see if this improves your eyes.

There are six main symptoms of eye fatigue syndrome: heavy eyelids and eye fatigue; Dry eyes with a foreign body sensation; blurred vision, double vision; eye soreness, eye pain, headache; photophobia, tearing; Bloodshot eyes, like chronic conjunctivitis, etc. Although these symptoms can be relieved with proper rest.

However, some people may develop eye diseases due to long-term excessive computer use. Common ones include dry eye syndrome, corneal damage, conjunctivitis, high intraocular pressure, myopia, etc.

The following methods can prevent eye fatigue: first of all, pay attention to eye hygiene when looking at the computer, that is, take a break of 5 10 minutes after working for 40 to 50 minutes. In addition, in order to relax the eye muscles, you can do eye exercises (close your eyes and massage the acupuncture points of the eyes) and eye exercises (open your eyes, move the eyeballs of both eyes to the greatest extent in all directions, up and down, left and right), and supplement them with hot and cold compresses alternately (about 6 to 10 minutes each time).

A warm compress is to allow blood circulation and relax the muscles, while a cold compress will reduce the congestion of the eyes. If you consciously blink your eyes more when looking at the computer, or frequently apply eye drops that moisten the eye surface, it is recommended to use eye drops (pearls, artificial tears, etc.) to relieve eye fatigue. At the same time, take care to ensure adequate sleep and exercise.
