What to do with the display bias

1, to avoid the display color Dim

There is a motley display, and GeForce FX 5200 display card directly connected to each text editing operation, the sense of the monitor can work, but once you enjoy multimedia information or play online games, you will obviously feel the display of the picture is dark, as if the gray, And in this state to try to adjust the brightness of the display parameters, the value of the maximum, the display screen still looks very dark. Obviously, the display's working status has deviated from "on the right track", when this phenomenon, we may wish to follow the following procedures to try to modify the system's display parameters:

Right-click the blank area of the system desktop first, from the pop-up shortcut menu, perform the Properties command, open the system's Display Properties Settings window, click the Settings tab in the Settings window, and click the Advanced button in the tab page that pops up to open the Advanced Property Settings window for the system. In this window, select the GeForce FX 5200 tab, and select the Color Correction menu command in the corresponding Options settings page, select the All option after the Apply color changes to Settings item, and then try to manually adjust the brightness switch, contrast switch in the Display control Panel, In order to improve the display brightness and contrast values, when you feel the system on the desktop color display normal, we will save the above settings. Next, into the multimedia playback screen or into the game state, in this state again and again adjust the Display control Panel brightness switch, contrast switch, until the display of the normal working state. Of course, if the display is only in the playback of multimedia information will appear when the color of dark phenomenon, we might want to open a multimedia file and perform the Color Correction menu command in a multimedia playback state, and then select the overlapping/VMR item in the corresponding Settings page, "Apply color changes to" settings, Then try using manual method to adjust the brightness switch, contrast switch in the monitor Control panel so that the brightness and contrast values of the display can be increased properly until the monitor is working properly in that state.

　　2, to avoid the display of color bias red

In the process of using a monitor for a long time, we often encounter a display suddenly red abnormal phenomenon, this phenomenon also shows that the display working state at this time has deviated from the "right track", that this kind of red phenomenon is how to cause it, how can we let the display working state back to normal?

For CRT type monitors, there are many reasons for the color bias of the display, and different reasons need to be used in different ways to respond correctly. Under normal circumstances, there are several main reasons that will cause the display color bias red: The first is in the mobile display position, inadvertently make the display inside the offset coil displacement, resulting in the display output color is impure; the second is that the monitor for a long time with a number of strong magnetic field of the equipment together, For example, if the monitor often and mobile phone, shielding function of the speakers and other power of the larger household appliances, the display will also be affected by the working state, which is prone to color-red phenomenon; The third is that the display has been used for a long time, some parts of the interior have been aging or damaged, For example, if the display inside the electron gun aging, or the internal degaussing line is damaged, the monitor can not be in normal working condition; The four is the monitor and the display card connection is not reliable or the contact between them is bad, this also can cause the display color to be red phenomenon. In addition to the above several main reasons, if the monitor accumulated too much dust, it is also easy to cause the display inside the work parts can not work properly, eventually will cause the display can not accurately display image color.

Under normal circumstances, display color bias if it is caused by the interference of the external magnetic field, then we can adjust the display position, let it away from those with strong magnetic field of household appliances, or use some professional tools to the display for degaussing operation, to ensure that the display of color output status back to normal; If the color bias of the display is due to the unreliable signal connection between the display and the video card or bad contact between them, all we need to do is unplug the signal cable from the interface of the display card and see if there is an oxide layer on the surface of the gold finger at the interface of the monitor signal cable. If an oxide layer is found, we simply clean the oxide layer that covers the surface of the gold finger, then reconnect the display card and tighten the fixing screws at the connector. If the color of the display is because the display "service" time is too long, or because of the internal signal line damage caused, we'd better ask professional people to repair, they must not open the display of the shell, to prevent further expansion of the scope of the fault. In addition, regular display of dust cleaning and other aspects of the maintenance work, will also ensure that the monitor working status can be normal for a long time.

Small tip: Of course, some monitors regardless of how to adjust and repair, will appear color red phenomenon, this phenomenon is sometimes a normal phenomenon, because the general professional display manufacturers in the production of monitors will be considered in different regions of the user or different countries to show the different color sensitivity, Therefore, the display will often add a color temperature adjustment function; For example, in Europe and the United States, most users of the display will appear color red phenomenon, because the region's display products in the default state will be the color temperature parameter set in the 6500K state, and this state of the display color looks slightly with some red, This makes it more comfortable for the user to appreciate the color.

　　3. Avoid color blur of display

There is a display has two years of work, has been working normally, but recently do not know how, every time after the operation will always find the display at the beginning of the color output is blurred, about more than 10 minutes after the display can be normal display screen, encountered this abnormal display phenomenon, How can we quickly and effectively get the display working back on track?

From the above display fault phenomenon, the author estimates that most of the fault is the picture tube attached to the work circuit has been damaged, because the focus of the cathode ray tube voltage is very easy to happen similar to the above fault phenomenon, causing this fault phenomenon is mainly the display of working time a long, So it's easy to attach a lot of dust near the focus hole of the CRT, these dust encountered moist air after easy to lead to the focus of the cathode ray tube hole contact performance greatly reduced, then the cathode ray tube of the focus of the voltage will naturally be affected and fall down, so that the display will be prone to focus on poor performance, The image shows a more ambiguous phenomenon. For the display's color output to return to its normal state, the only effective way we can do that is to replace a new CRT tube seat, if we do not have this tube seat, we can consider the use of medical alcohol to the old picture tube seat dust cleaning operation to ensure that the cathode ray tube focusing voltage is not affected by dust. From the above symptom, it is important to keep the monitor on a regular basis for hygienic cleaning operation. Tips: To make your display work efficiently, we must not ignore its use of the environment, such as not allow it to work in the dust dance environment, in the use of the display should be used to cover the display, or dust constantly attached to the display inside the components, circuit board, which may affect the normal distribution of the display heat , so that the components, circuit board with the increase in operating temperature, speed up the aging speed, affect the life of the display. And the dust can absorb moisture in the air, so that the display of electronic circuits and components corrosion.

　4, avoid the display color clutter

Here the display of color clutter, in fact, refers to what we often say the display output screen failure phenomenon. One monitor each time the system is switched from hibernation to a normal working state, display color clutter, sometimes the monitor screen does not show any content, do not know the display of this abnormal display phenomenon is how to cause, how do we let the display work status back to normal?

Encountered this phenomenon of display failure, most of the display of the input power part of the problem, or the monitor directly connected to the display card is not working properly. We know that if the monitor's input power is not stable or power is not enough, it is easy to cause the display of color clutter, caused by this reason most of the fault occurs in the use of old power or poor power of the computer system, because these computer systems often can not provide a large enough power to the display, Then the monitor will not work properly can be understood, so to avoid this phenomenon, we first need to ensure that the computer system equipped with a good quality power supply; If the power supply to the computer is often fluctuating, and the amplitude of fluctuation is relatively large, we'd better equip the computer with a voltage-stabilizing power supply, This will not only ensure that the display can work properly, but also conducive to the extension of the computer's service life. After excluding the power factor, if the monitor still does not work, we need to check the current display card driver is normal, if the display card driver is not normal, it is also easy to cause the display color clutter; in general, We'd better go to the official website of the corresponding model card to download the latest driver for the display card, instead of using any other bugs driver.
