Cleverly keep the monitor away from the black screen "harass"

In the day of intimate contact with the computer, we often encounter the phenomenon of black screen display, encountered this phenomenon most people will be conditioned to think that their display must be damaged, the rest of their work is to ask professionals to repair the monitor. In fact, not all black screen phenomenon is caused by the display itself, there are some operational details will lead to the display of black screen phenomenon, in the face of this kind of non-hardware damage black screen phenomenon, we can prescribe the right remedy to keep the monitor away from the black screen "harassment"!

　　Adjust refresh frequency, away from all black screen "harassment"

Units in the Office of the computer has been installed in the Windows operating system, because the driver is not free to use the computer often, resulting in the display resolution parameters are often adjusted to 640x480, so that the display can not be realistic display images or other content. Recently, when the author tried to adjust the resolution of the display to 800x600, and the "color quality" adjusted to 32-bit true color, and then restart the computer system, the author saw the display turned into a black screen; although, the author will be the resolution of the monitor again restored to the previous 640x480, The display's black screen phenomenon no longer occurs. But let the author always Wonder is that the monitor can not work in the 800x600 resolution state?

In view of the low resolution of the monitor can work properly, I think the display inside the possibility of failure of accessories is very small, the display of black screen phenomenon is mostly the display mode is not set up correctly caused. Because the computer in the office has been "in service" for a long time, the author estimates that the computer's display card driver has been old, perhaps the above black screen phenomenon is due to the display card driver, for this author Yibu, over Boots, back to the Internet to download the display card of the latest driver, And the driver of the display card is updated. However, the display card-driven update operation does not bring significant results.

Later the author to the online search related information found that when the quality of the display card is not very good, the display of high frequency of refresh can easily lead to the display of black screen phenomenon. According to this phenomenon, the author examines the office of computer display properties, sure enough to see the display of the refresh rate has been set to 85Hz, when the author of the number adjusted to 65Hz, and then try to adjust the resolution of the monitor to 800x600, and finally restart the system, found that the display of black screen phenomenon really disappeared. In the later use of time, although the display will occasionally have a black screen phenomenon, but the author will display the color number from the original 32-bit true color modified to the current 16-bit true color, such a setting, the computer's monitor no longer has a black screen phenomenon. Summing up the black screen phenomenon, the author thinks that when the display card has been working for a long time, the performance of all aspects of it may drop, at this time we must be in time to its performance indicators a slight drop of a grade, perhaps to let the display card and monitor continue to work properly.

　　Modify display properties, away from some black screen "harassment"

Once a friend in the author's computer to play the game, just at the beginning of the display work is 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 contents of the top and bottom are partly black screen phenomenon

At the beginning, I thought that the symptom was caused by the damage 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 for the corresponding item, click the Uninstall button in the tab page, To remove the current display card driver, reboot the computer system, and let 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 display 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 again into the Local 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 display, in which I check the General Settings option, the adapter settings option, Do not see any exception, when you see the "Monitor" setting options, I see a more than one display driver option, the author tried to remove the driver option, and then restarted the computer system, the results found that some of the display of black screen phenomenon immediately disappeared.

　　Adjust startup options, away from the short black screen "harassment"

When we start the Windows XP system, we may encounter a strange phenomenon, that is, after logging into the Windows XP system, the monitor just displays the system tray area of volume and system time icon, the display screen suddenly appears a short black screen phenomenon, The phenomenon normally sustains pause seconds, and then we can see the normal Windows XP system desktop. In addition, whenever we go into the System Display Properties window, click the "Advanced" button, and open the computer's Plug and Play display property interface in the Advanced Settings page, we also find that the display screen will appear pause seconds a short black screen phenomenon, and even if we reinstall the computer system, The temporary black screen of this display still exists, what is going on?

From the above fault phenomenon, we can see that most of the time the monitor is able to work properly, which indicates that the monitor itself does not have hardware damage. Considering that the temporary black screen phenomenon only appears in the system startup this moment, to this end, I think this phenomenon is mostly caused by the system started some special applications, so we might as well check the local computer's startup project group contains what startup options, and then cancel some unwanted startup items to load, It is believed that most of the display can eliminate the short black screen phenomenon.

When you cancel some unwanted startup item loading operations, we can click the Start/program/start option first. Check the boot menu group for unwanted startup options from the Pop-up submenu, and if so, right-click the option and execute from the pop-up shortcut menu. Delete command to cancel the load of the selected startup item. After that, we click the start/Run command again, in the System run text box that pops up, enter the string command "msconfig", click the Enter key, open the System Configuration Utility dialog box, click the "Start" tab in the dialog box, and go to the label page as shown in 1. Here we will see more startup projects, choose what you don't need or not load the necessary options, and then cancel all of the selected options, click OK, and then restart the computer system, believing that the display's brief black screen will disappear.

Of course, this is a relatively complex phenomenon if the display's short black screen appears at regular intervals. There are many reasons for this phenomenon, for example, the display card driver version is not appropriate, the display inside the component has a slight damage, or the computer's power input part of the problem, and even some components of the computer board may be damaged, so we have to all the possible factors, In order to completely eliminate the temporary black screen phenomenon of the periodic.
