Computer Monitor Slightly Flickering Solution 1:
1, check whether your graphics card is loose, try uninstalling the computer's graphics card driver and installing a stable version of the driver. Sometimes we enter the computer's monitor refresh frequency, but found that there is no refresh frequency to choose from, this is due to the former graphics card driver is incorrect or too old caused.
2, the purchase of earlier computers are prone to this problem, this time do not use the purchase of computers with the CD-ROM driver, you can go to the Internet to download the latest version of the corresponding graphics card driver, and then open the ? The system? Properties window, click? Hardware? window. Device Manager? button to enter the system's device list interface.
3. Right-click the graphics card option in the interface, and from the pop-up context menu, click ? Properties? command, and then in the pop-up graphics card properties settings window, click the ? Driver? tab, and then in the corresponding tab page, click? Update Driver? button on the corresponding tab, and then gradually update the graphics driver to the latest version according to the wizard prompts.
4, the computer system restarted a bit, if the driver installation is appropriate, there will be LCD monitor refresh frequency selection, and then set the refresh rate to 75Hz or more to solve the problem of computer screen flicker.
Second:
1, desktop right-click - & gt; Properties - & gt; Settings - & gt; Advanced - & gt; Monitor - & gt; screen refresh frequency, CRT adjusted to 75Hz or more laptop LCD screen LCD to 60Hz can be.
2, in fact, the LCD monitor screen shake the most important reason is that the LCD monitor refresh frequency is set below 75Hz caused by the screen at this time will often appear to be shaking, flickering phenomenon, we just need to adjust the refresh rate up to 75Hz or more, then the phenomenon of computer screen shake will not appear again.
3, sometimes due to the use of ` LCD monitors have been high, there will be jittery phenomenon. In order to test whether the display of the internal electronic components are aging, you can connect the faulty display to someone else's computer to test, if the fault still disappears, indicating that the display is bad, need to be repaired.
Computer monitor slightly flickering solution two:
First, the screen backlight caused by the screen flicker
Failure to perform: laptop backlighting irregular flicker, the frequency is very fast, and sometimes flash a few times, and sometimes it will be a few minutes to continue.
This situation is due to the screen backlighting power supply to the high-voltage board is not stable or the lamp joints at the solder joints are not firmly connected to the fire. The high voltage board caused by the screen flicker can be replaced on the high voltage board to solve the problem. In our daily maintenance, sometimes for the price of the original high-voltage board and the source of reasons have to modify the general high-voltage board to achieve the purpose of maintenance.
Lamp connector soldering caused by the screen flicker longer consequences are more serious, carefully observe the lower left corner of the screen or the lower right corner there will be a small piece of black shadow, this is the connector soldering caused by the fire has been burned around the components of the paste. After the repair can not remove this small piece of shadow.
Second, the motherboard charging switching circuitry caused by the screen flicker
Failure to show: the notebook in the battery and power adapter at the same time will not be regularly screen flicker, at the same time the lower right corner of the screen charging indicator signs will keep switching, a single power supply when the failure phenomenon disappeared.
This failure is relatively rare in notebook repair, mainly due to the battery switching circuit on the motherboard does not component instability caused by the motherboard charging circuit components can be repaired to fix the problem.
There is also a situation due to the quality of the power adapter, where the only good reminder of the power adapter as much as possible with the original, or with a better quality of the OEM products. Don't be tempted to use tens of dollars of power, this power in the hands of the light, the material used can be imagined.
Third, the screen itself is bad caused by the screen flicker
In fact, in recent years by this reason caused by the laptop screen flicker accounted for a large proportion of the reason why it is placed in the last because of this situation is limited to the same batch of several models of notebooks. The specific fault performance is: generally first in the laptop screen will have a bright line at the bottom, after a short time, the bright line will evolve into a full-screen flicker.
