How to repair a monitor

Display is almost every computer player to face every day, its work "performance" of good or bad, not only affect our day-to-day office efficiency, but also with our eyes "feeling" closely related. Let the monitor work daily, let it work "performance" has been in a good state, this is the tireless pursuit of every computer player; however, the display in the long time for our "service" process, there will inevitably be a variety of unexpected illnesses, All we can do is try to get rid of the various diseases of the monitor as soon as possible and make sure the display can provide us with "service" efficiently.

1, focus on driving, dispel resolution can not adjust the disease

Recently, the unit is equipped with a WVGA wide-screen display, it can support the display resolution standard for 1280x800, when the author tries to enter the system's Display Properties Settings window, to set the system's display resolution to 1280x800, But found that the system's Display Properties window does not provide 1280x800 this resolution option, but provides a maximum only to 1280x768 such a standard resolution, but the selection of this standard option, the author found that the wide-screen display is still not normal, so to say, Can't we just adjust the output resolution of the wide-screen display to 1280x800?

The author according to his years of experience, that the disease is actually a display identification problem, as long as the monitor to reinstall the driver will be able to solve the problem, but the purchase of the Monitor's colleagues said the manufacturers did not have a monitor driver. In this case, the author believes that there is no original driver, as long as the operating system to correctly identify the monitor can solve the problem. Because the wide-screen monitor is connected to the Windows 98 system workstation that is installed, the author first opens the Device Manager window for the workstation, selects and deletes the target monitor in the window, and then restarts the computer system again. The system automatically recognizes the wide-screen display during startup and automatically installs the driver for the device. Full thought this time can be in the System Display Properties window, you can choose to 1280x800 this non-standard resolution options, but who had thought when the author again open the System Display Properties window, still did not find the 1280x800 resolution option.

Later colleagues reminded the author timely, will not be the operating system caused by it, because the manufacturers in the test of the monitor is used in Windows XP system. I do not have any Shifa at this time, think for a long time to decide to reinstall the computer as a Windows XP system, after a long installation waiting, the author is full of hope to enter the new system to display the properties of the window, but the final result of the author was disappointed. Because in the purchase of a wide-screen display, the seller does not have the original driver for the display, the author had to search according to the model of the monitor whether there is a corresponding model of the driver, and finally Kung Fu, found the corresponding display of the latest version of the graphics driver program; After the author through the System Device Manager window The update Driver feature, upgrade the current monitor's driver to the latest version, and then restart the computer system again, this time the author once again into the System Display Properties Settings window, finally see 1280x800 This non-standard resolution option, select this option and click the Display Properties window "OK" button, the wide-screen display can finally work in the 1280x800 resolution state.

Summing up the process of elimination of the disease, I think to be able to adjust the output resolution of the display, you must first ensure that the monitor driver installed correctly. In the correct installation of the premise of the display driver, found that the monitor can not be displayed normally, it may be possible to update the display card driver, after all, the display card in the latest driver "driver", in order to play a better working state.
2, focus on attributes, remove the reboot after the display of abnormal disease

Once the author in their own computer to play the game, just at the beginning of the display work is very normal, but not a good time, the computer suddenly panic phenomenon, had to restart the computer system; But after the successful restart, the author found that the monitor can not display the normal content, The specific fault phenomenon is that the contents of the display screen can be displayed normally, but the top and bottom contents are black screen.

At first, the author estimated that the failure was caused by the failure of the display card driver. So the author right click on the system desktop "My Computer" icon, from the pop-up shortcut menu to perform the "Properties" command, open the system's Property Settings window, click the window "Hardware" tab, and click the Device Manager button in the corresponding tab page, open the System's Device List window, expand the Display card option in the window with the mouse, double-click the standard VGA graphics adapter item, open the Driver label page, and click the Uninstall button on the page. To remove the current display card driver, reboot the computer system, and have the system reinstall the display card driver automatically. When the display card driver is reinstalled, the author finds that the contents of the display screen at the top and bottom are still black screens. Later, the author tried to modify the display properties of the system, but this effort is still unable to make the monitor work properly. Under the helpless, the author had to replace the new display card, the original thought this will certainly solve the problem, but who had thought, even if the replacement of a new display card, monitor the symptoms of the phenomenon of everything as usual. Why does the monitor still not work after the new video card is changed? The author estimates that the fault phenomenon is mostly caused by the display property of the system, but it has nothing to do with the performance of the display card. To this end, the author has reopened the System Display Properties window, click the Settings tab in the window and click the Advanced button in the corresponding tab page to go to the Advanced Properties setting interface of the Monitor, in which I check the General Settings option, the adapter settings option, and I don't see anything unusual. , when you see the "Monitor" settings option, the author sees a more than one display driver option, the author tried to remove the drive option, and then restarted the computer system, the results found that the monitor can work immediately!

3, focus on the power supply, dispel frequent flicker of the display of the disease

There is a TCL MF712 model of the display, the resolution of 1024x768, refresh rate of 75HZ, the normal work of the monitor can work normally, but once to the peak period of electricity, the monitor screen will keep flashing, do not know how this symptom is caused, What methods should we use to dispel the frequent flicker of the display?

According to the above fault narration, the author thinks that the frequent flicker of the display is mostly caused by the instability of the input voltage. Generally speaking, in the peak period of power, the display input voltage fluctuation amplitude, if we are currently using the quality of the display is not too good or the display time is too long aging phenomenon, then this type of display internal voltage filter circuit performance is not too ideal, So the unstable input voltage can not be completely filtered out by the filter circuit, so the phenomenon of frequent flicker of the display is inevitable. To effectively avoid this phenomenon, we can connect the power supply plug to the monitor power supply, if there is no steady power supply, then as far as possible to avoid the peak power, I believe that the display of frequent flashes of the disease will not often attack.
