What to do if the monitor screen is not clear?

Regarding the problem that the monitor screen is not clear, what should I do? Then let me tell you the reasons and solutions for the monitor screen being unclear. I hope it can help you. !

Solution 1 for unclear monitor screen:

The CRT monitor is too old and the refresh rate cannot keep up.

The higher the refresh rate, the better, the more stable the image, the more natural and clear the image display, and the less impact on the eyes.

The lower the refresh frequency, the more severe the flicker and jitter of the image will be, and the faster your eyes will tire. It is better to change to an LCD, which should be a monitor.

Change to a lower system, such as installing XP system. If you change to WIN7, it will be blurry. If you change to XP, it will be clear.

Secondly:

1. Vibration during transportation or use causes the focus potentiometer of the FBT (line output transformer) to loosen or shift, causing the focus added to the CRT to Voltage changes (deviating from the optimal voltage value adjusted at the factory), causing the screen to blur;

2. The environment around the monitor is humid, causing the discharge ring (hemisphere) of the focusing pin on the CRT tailstock plate Corrosion occurs and blurring occurs when the CRT is first powered on;

3. The gap between the focus pole and the accelerating pole (G2) in the CRT tube is caused by the manufacturing process or debris in the CRT cone glass envelope. Static dust is generated, forming and resistance causing serious damage to the screen.

Solution 2 for unclear monitor screen:

Possible reason 1: The resolution is not set to the optimal resolution of the LCD.

Generally, novice users will encounter this problem. More experienced players know that LCD monitors have their own most suitable resolution. This is determined by the physical structure of the LCD panel. For desktop monitors, For computers, the best resolution is usually 1024768 for a 15-inch LCD monitor and 12801024 for a 17-inch LCD monitor.

Solution: Right-click on the desktop, select Properties, and then select the Settings tab. In the lower left corner of the menu that appears now is the slider for adjusting the resolution. Drag it to the maximum resolution of the monitor. Select the best resolution, then click Apply. The system will prompt you whether to keep the changes, just select OK.

Possible reason two: The digital signal phase or pixel setting is incorrect.

This possibility is relatively small, unless the signal phase and pixels have been mistakenly adjusted in the LCD control menu, or the graphics card output signal does not match the LCD monitor.

Solution: Very simple, you can adjust it to normal display through the control keys on the LCD monitor panel. First, select automatic image adjustment or restore factory settings. If the image is still blurry at this time, enter the image adjustment menu and manually adjust fine-tuning and sharpness (also called phase and pixel adjustment). Generally, LCDs have Chinese menus. , the author will not introduce it in detail.

In addition, if you are using an ATi graphics card, you can also adjust the synchronization options in the Control Panel/Display/Settings/Advanced/Display/Monitor/Advanced menu, and click on the vertical, horizontal, and composite options respectively. Find out which combination makes your LCD display the clearest.

Secondly:

Most monitors provide an AUTO button, which can solve the problem with just one press.

It can be said that all monitors will have this problem, including LCD and CRT. The solution, which is provided by major monitor manufacturers, is to "AUTO" the monitor during normal use.

Many monitors will provide this button directly, just press it.

If your monitor does not have it, you can go into the menu and look for it. Ninety percent of monitors will provide it. Some monitors directly call it "AUTO", and some monitors call it "Auto Adjust". In fact, they all mean the same thing.

If you can’t find this item after searching for it, then click “Reset” to restore the monitor to the default, then 99% of the monitor will automatically adjust to the best state.

Counterfeiting is the source of trouble! Inferior wires are the source of trouble

There are three common types of cables used by hosts to connect monitors: VGA cables, DVI cables, and HDMI cables. In addition, There are also uncommon DP lines. Except for the DP wire, which is quite expensive, the other three types of wires are quite cheap. They cost 5 yuan or 10 yuan each. This price is a fair price, and the quality of most wires is also good. But if you click on it occasionally, you may end up with inferior wire.

If the problem is still not solved after trying the two methods mentioned above, you need to investigate whether there is a problem with your connecting cable. The simplest solution is to replace the monitor cable.
