Editor PHP Strawberry akan memberi anda pengenalan terperinci kepada punca biasa paparan kabur dan cara menyelesaikannya. Fahami punca ini dan kuasai penyelesaian untuk memulihkan pengalaman paparan yang jelas dengan mudah.
Monitor komputer adalah salah satu peranti yang amat diperlukan dalam kerja dan hiburan harian kita Namun, kadangkala kita mungkin menghadapi situasi kabur pada monitor, yang membawa masalah kepada penggunaan kita. Mesti menyusahkan. Dalam artikel ini, kami akan membincangkan kemungkinan punca monitor komputer kabur dan cara membetulkannya untuk membantu anda menangani masalah tersebut dengan lebih baik.
Apabila monitor kelihatan kabur, perkara pertama yang perlu disahkan ialah sama ada sambungan itu baik. Periksa sama ada kabel sambungan antara komputer dan monitor dipasang dengan ketat dan sama ada ia longgar atau mempunyai sentuhan yang lemah. Kadangkala kabel sambungan yang tidak stabil akan menyebabkan penghantaran isyarat yang lemah, mengakibatkan paparan kabur pada monitor.
Jika sambungan disahkan, anda boleh cuba melaraskan resolusi monitor. Buka tetapan paparan komputer anda dan cuba laraskan resolusi kepada resolusi terbaik untuk monitor anda. Memilih peleraian yang betul boleh meningkatkan paparan dan membantu menyelesaikan isu kabur.
Satu lagi punca biasa monitor kabur ialah tetapan monitor itu sendiri. Melalui menu atau butang monitor, anda boleh cuba melaraskan tetapan seperti kecerahan, kontras, rona, dll. untuk menjadikan paparan lebih jelas. Kadangkala kontras kecerahan terlalu tinggi atau terlalu rendah juga boleh menyebabkan hasil paparan yang lemah.
Pemacu kad grafik yang lapuk atau tidak serasi juga boleh menyebabkan monitor kabur. Anda disyorkan agar sentiasa menyemak dan mengemas kini pemacu kad grafik untuk memastikan keserasian dan kestabilan dengan monitor. Pemacu kad grafik terkini boleh didapati di laman web rasmi pengeluar dan ikut arahan untuk mengemas kininya.
Jika tiada kaedah di atas menyelesaikan masalah paparan kabur, mungkin terdapat kegagalan perkakasan. Anda boleh cuba menukar kabel atau menyambungkan monitor ke komputer lain untuk ujian bagi menentukan sama ada isu itu adalah dengan monitor itu sendiri atau dengan peranti lain. Selepas mengesahkan bahawa ia adalah masalah perkakasan, adalah disyorkan untuk menghubungi perkhidmatan selepas jualan atau pusat pembaikan tepat pada masanya untuk diproses.
Monitor kabur adalah masalah biasa, tetapi ia biasanya boleh diselesaikan dengan mudah dengan beberapa tweak dan semakan mudah. Pastikan sambungan adalah baik, laraskan resolusi yang sesuai, semak tetapan monitor, kemas kini pemacu kad grafik, dan akhirnya semak kemungkinan masalah perkakasan Kaedah ini boleh membantu anda menyelesaikan masalah monitor komputer yang kabur. Saya harap artikel ini berguna kepada anda, terima kasih kerana membaca!
Pelarasan resolusi yang salah: Monitor LCD berbeza daripada monitor CRT Setiap monitor LCD mempunyai resolusi yang optimum. Kebanyakan monitor menyediakan butang AUTO, dan menekan AUTO semasa penggunaan biasa monitor boleh menyelesaikan masalah.
Menggunakan wayar inferior: Terdapat tiga jenis wayar yang biasa digunakan oleh hos untuk menyambungkan monitor: wayar VGA, wayar DVI, wayar HDMI dan wayar DP yang tidak biasa.
Kegagalan kad grafik hos: Riak air muncul pada monitor Kesalahan khusus adalah hos yang sama Tidak kira apa monitor yang diganti, akan sentiasa ada riak air.
Desktop? I think the probability of a monitor problem is low. If it's not a setting problem, it's probably the graphics card. 1. Incorrect resolution adjustment: LCD monitors are different from CRT monitors. Each LCD monitor has its own optimal resolution. If you use a non-optimal resolution, it will definitely be blurry. But some users don't care about these, whether it is a wide screen or a regular screen, and they all use 1024X768 or 1280X1024 resolution, then most of the monitors must be blurry and flickering, with water ripples appearing. The problem to be solved is also very simple, just adjust the monitor to the best resolution. The adjustment method is also very simple. Right-click on the desktop and select Properties, click Settings, and pull the screen resolution scroll bar. 2. Most monitors provide an AUTO button. Press it lightly to solve the problem. It can be said that all monitors will have this problem, including LCDs and CRTs. 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 are directly called "AUTO", and some are called "automatic adjustment". In fact, they all mean the same thing. If you can't find this item after searching all over the place, then click "Reset" to restore the monitor to default. Then 99% of the monitors will automatically adjust to the best state. 3. Counterfeiting is the source of disaster! Inferior quality wires are the bane. Generally, there are three common types of wires used by hosts to connect monitors: VGA wires, DVI wires, and HDMI wires. In addition, there are also uncommon DP wires. 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 something wrong with your connecting cable. The simplest solution is to replace the monitor cable. 4. It has nothing to do with the monitor! The host graphics card fails. Water ripples appear on the monitor. The author has seen it twice due to host problems. The specific fault symptom is that the same host will always have water ripples no matter what monitor is changed. This problem can be said to be a flaw, and even if the host is sent for repair, it will probably not be solved. The simplest way is to add a graphics card to the barebone system (if it can be added). After adding it, the problem is almost 100% solved. If your barebone system is too small, or there is no interface on the motherboard to connect a graphics card, then I can only say sorry to you. This problem is innate, and even if you send it for repair, it will probably be in vain.
What are the causes of system font blur?
After using a computer with an integrated graphics card for a long time, the fonts on the monitor screen will become blurred, especially on LCD monitors. Blurred display fonts can be prevented. The author will analyze for you what factors cause system font blur.
1. Host power management settings:
When many users install the system, in order to achieve energy saving, they often limit the time for the monitor, hard disk and power supply in the host power management settings; after the time is up, the restricted equipment Then there will be a closed state, and the performance directly on the monitor will be no display. Users often think that the monitor is faulty and the screen will be black intermittently. Many customer complaints are due to this reason. At this time, as long as the setting items are corrected, it will be OK.
3. Requirements for matching graphics cards:
The input signal requirements for the monitor are (taking the 797 model as an example):
Video signal: a. Type: simulation signal b. Standard: 0.7Vp-pc. Input impedance: 75Ωd. Polarity : Positive polarity
Horizontal synchronization: a. Type: TTLb. Input impedance: minimum 1KΩc. Polarity: positive or negative d. Frequency: 30KHz~96KHz
Horizontal synchronization: a. Type: TTLb. Input impedance: minimum 1KΩc. Polarity: positive or negative d. Frequency: 50Hz~160Hz
Since the graphics cards on the market are uneven, if the output signal of the graphics card is not within the above range, there will be no display, image phase deviation, image deformation, etc. Users often judge that the display is defective, but in fact the root cause has not been found; except for no display beyond the frequency range, other image defects can be adjusted through the OSD menu adjustment function;
4. Menu function adjustment and reset function:
(1) .Menu adjustment function:
In the OSD menu, there are nearly 20 adjustment functions such as contrast, brightness, horizontal phase, horizontal width, field center, field width, pin cushion shape, trapezoid, parallelogram, asymmetric type, etc., providing users with Use it when entering a new frequency, mode or changing the set mode. All preset modes can be automatically stored and memorized after completion.
(2).Reset function:
5. Water ripple phenomenon:
Water ripple Due to the inherent moiré phenomenon when electron beams scan phosphors, any display will have varying degrees of performance; due to the high resolution of new displays, this phenomenon is more common, but it is not a malfunction.
Solution: (1). Change the resolution setting to: 800 * 600 @ 75Hz or above, adjust the contrast to the maximum, and set the brightness to 60~70% (or the background color just disappears). It can be improved, but it cannot be cleared. ;(2). Use Moore adjustment function to completely eliminate ripple diffraction; because the factory uses a standard signal source during production, it is impossible to predict which graphics card will be equipped after leaving the factory, and the signal output of each graphics card is very different, so the factory leaves the factory Set its value to 0 at all times. Users can use the Moore adjustment function to eliminate the water ripple phenomenon after actually connecting to the host.
The following is a solution to the problem of blurry display on the monitor for your reference. Adjust the optimal resolution. When encountering a blurry display, it may be that the resolution of the monitor is not set to the optimal resolution. Each LCD monitor has the most suitable resolution. This is determined by the structure of the LCD panel. Different The optimal resolutions vary depending on the size of the LCD panel. You can refer to the previously published article "Introduction to LCD Widescreen Monitor Specifications". Generally, the best resolution recommended for LCD monitors is the one that is most suitable for you. Right-click on the computer desktop, properties, and adjust to the best resolution in the settings options. Refresh rate Many people think that refresh rate is only important when using CRT monitors, and LCD monitors have nothing to do with it. The first thing to know is that CRT monitors and LCD monitors work differently. The LCD monitor needs to convert the information coming from the graphics card, and the refresh rate still has an impact on the final image output effect. The refresh rate can be found in the screen refresh rate drop-down list under Settings-Advanced-Monitor in the desktop properties.
1. Check whether the picture tube is aging. For general maintenance personnel, due to the lack of special instruments and equipment, they can only use indirect methods.
2. Use a high voltage meter to directly measure the anode high voltage. If there is no high voltage meter, never use a multimeter to directly measure the anode high voltage. Commonly used methods are:
When powering up the monitor, pay attention to whether there is an obvious high-voltage charging sound from the deflection coil. If there is, generally high voltage will not be a big problem:
1.
Open the computer interface, right-click on a blank space on the computer, and select "Screen Resolution" from the menu that appears.
2.
In the opened interface, find the location of "Resolution".
3.
Click the drop-down button behind the resolution, and a list of resolutions will appear.
4.
Drag the slider to the maximum value. The relationship between the computer's resolution and the size and clarity of desktop icons is: the greater the resolution, the smaller the desktop icons and the higher the clarity. The smaller the resolution, the larger the desktop icons and the lower the clarity.
5.
A "Display Settings" interface will pop up. Click the "Keep Changes" button to make the computer clear.
Step/Method 1
First, click Start, then click Control Panel
Step/Method 2
Then enter the display in the upper right corner of the control panel
Step/Method 3
Click to adjust screen resolution
Step/ Method 4
On the right side of the resolution below, select the recommended resolution, usually "1366×768". Click OK
That’s it, after all, the price is here. The problem you are talking about is the issue of uniformity. If you want a very uniform grayscale performance for a panel as large as 32, you need a high-end monitor with partition compensation. Basically, eizo and nec level monitors require 3w+.
However, for daily use, it does not display a monochrome screen all the time, so these problems cannot be seen.
If you still don’t give up, you can contact Dell after-sales service for a replacement, and they will arrange for someone to come to your doorstep with a new one to replace it with. My friend and I changed it innocently a few years ago. After changing it, you will find that it is still the same. Because we are really using it for professional purposes, our eyes have been spoiled by the master, and we have no money in our pockets, so we want to use a small amount of money to buy a quality monitor that is not inferior to professional monitors. It is very naive.
I don’t know what you are using this screen for. If you want good quality, I think you can put it on 32-inch and 4k. If you go to 27-inch, you can get a pretty good 2k screen for 4999. If you play games, I recommend buying a va. You can get a 32-inch 4k screen for 3,000. If you want something with better overall quality, this is actually pretty good for you, and you won’t see any problems with it in daily use.
Right-click on the desktop, Properties-Appearance-Effects-Use the following methods to smooth the edges of screen fonts-check the box and select "Clear". If it still doesn't work, ask again.
If the computer monitor is blurry and unclear, it can be repaired. However, if you cannot repair it yourself, you can take it to a repair shop for repair
