When you use the computer, have you ever encountered sudden blurred display? At first I thought it was my illusion, but later I found that it was a blurry font and blurry picture, which made people feel uncomfortable when I saw it.
If you encounter such a situation, don’t settle it. Find the reason in time to restore the monitor to normal. Usually there are several reasons for this situation in the computer. You can gradually find the problem and operate according to the solution.
01 Resolution problem
The resolution supported by each computer is different, it has its own best resolution. The best resolution allows you to see the clearest and most accurate images on the screen. Settings above or below the machine's display resolution will cause blur or distortion of the display.
The best resolutions for computers of different sizes are also different. For example, laptop 13.3 inches is suitable for 1280*800; 14.1 inches is suitable for 1366*768; 15.6 inches is suitable for 1600*900.
Operation method is very simple. Open the computer [Settings] and find the [System], and then select the [Recommended] resolution as shown in the above picture.
02 Check the graphics card driver
The good driver plays an important role in the graphics card, and graphics card also plays a decisive role in the quality of the picture in addition to detecting the computer's hardware conditions and system environment. Therefore, when the computer video device is blurred or there are water ripple, we can first check the graphics card to see if it is inserted accurately and whether it is loose.
Then check whether the computer has the driver installed, whether it is the latest version, and check whether it matches. In addition, there are two types of graphics cards: independent and integrated. If you want high-quality image effects, independent graphics will be better than integrated graphics.
03 Check the display
screen is displayed through the display. If there is a problem with the display, it will inevitably affect the picture quality. Oxidation, damage, moisture, etc. of the monitor will affect the blurred picture.
electrical products should not be used for a long time, as it is very easy to cause oxidation points on the interface or oxidation points on the monitor. The solution is to sand the interface with sandpaper to remove the oxidation points. If it is caused by moisture, you can open the back cover and blow it with a hot air duct until it feels no longer wet. If it is caused by damage in some place, you need to go to a professional repair shop to deal with it.
04 Check the wire for fake and shoddy
There are four types of wires connecting the monitor to the host, namely VGA wire, DVI wire, DP wire, and HDMI wire. Take HDMI cable as an example. If you buy a low-quality cable, it will cause blurred display and smear.
In fact, the current lines sold on the market are not expensive. But you can still see the obvious difference. This is because many inferior wires have low cost and are naturally low in price, but the risk factor for using such wires is very high. It should be noted that in addition to providing screen display, network speed and other functions, the outer skin of the wire also needs to have good fire and wear resistance.
And high-quality wires will not only not affect the picture quality, but will also improve the picture quality within the range and enjoy better screen viewing effect. If you find that it is caused by the wire during the inspection, you need to replace a high-quality trustworthy HDMI cable.
As shown in the above picture, the Green HD 156 HDMI cable supports 2K/144Hz screen output. The interface shell uses zinc alloy , which is wear-resistant and scratch-resistant. The thread body is protected by PVC and braided double-layer outer skin, so there is no need to worry about breaking and breaking the skin. It effectively protects the internal wire core and ensures the operation of the computer.
05Electromagnetic interference
When we ruled out all the problems caused by the computer itself, the display screen is still blurred. Then, it can only be caused by external factors.
When we are using a computer, there are multiple electrical devices around us working. They form many electromagnetic radiation sources next to the computer, and will continuously emit electromagnetic waves interference display. What's more, if there are large cables not far from home, it will also have a certain impact.
monitors contain two types of shielding covers and do not contain metal. The reason for the shielding cover is that it can eliminate electromagnetic interference, but because the monitor generally has a large workload and generates a lot of heat. So there is a gap in the shield for heat dissipation. The monitor without shielding cover is completely subject to electromagnetic interference, and the greater the interference, the more severe the impact it will be.
