How to check the monitor failure

1. Display image offset

Its main manifestation is: In windows9x/me the display resolution is adjusted to 800x600 @85hz and full screen display, but in other display mode or Ms―dos screen is significantly left shift. This happens in the early 15-inch low display, and there is no better way to fix it than to adjust the display mode in each display mode. In the new monitor because of the built-in display mode memory and other auxiliary systems, the use of a certain mode of adjustment, can be guaranteed in each display mode can be correctly displayed, this situation is basically disappeared.

Another condition is that the monitor is out of sync. For example: When running certain game programs, the screen suddenly prompts: "Out of sync Range", then the program automatically quits. When some programs require a display refresh rate greater than the actual resolution of the display, there is a hint beyond the sync range, and sometimes you can turn the monitor off before you turn it on, and then reset the appropriate display resolution.

2. Display color bias

There are three main causes of color bias on the monitor:

(1) The connection between the video card and the monitor is bad contact signal line. You can reseat the VGA connection plug in the case of shutdown, and carefully check whether the pins appear bent and deformed, whether the signal line appears broken.

(2) If only one part of the screen, especially the screen of the Four Corners appear color, under normal circumstances is due to strong magnetic field interference caused. At this point can check the display around the presence of strong magnetic equipment, such as speakers, high-power power transformers, etc., try to move these devices away, such as the color is still no improvement, you need to consider the display to do degaussing processing.

(3) Some monitors have the color temperature setting function, if the setting has the error also may cause the partial color fault, but this kind of partial color's actual performance is full screen overall bias to a kind of background. This failure can be resolved simply by adjusting the color temperature parameters correctly. If in any case adjust the color temperature parameter bias still does not improve, the problem comes out of the display inside the chroma output transistor is "soft breakdown", or bias potentiometer contact bad. In this case, it is better to send the fault monitor to the professional maintenance staff.

3. Some programs cannot run after installing the display driver

Some branded displays can cause some applications to not run after they have been installed with a dedicated driver attached to the CD. For example, a compatible computer using the Accor as786t display, after installing a dedicated driver, opens the Photosop

5.0 Simplified Chinese version, and runs to "initializing the ICC engine ..." (ie, color management), the screen appears illegal operation prompts and causes the program refused to enter. Once tried to uninstall Photoshop after reloading, but useless, and then simply format the C disk and reload the system, but also did not see any effect.

Finally, the solution was found through many tests. Right-click on the desktop to select Properties to open Display settings, click the setting option above, and then click the Advanced button in the lower right, clicking the Color Management option in the dialog box that appears. At this point, you can see the color profiles associated with Accor as786t, then in many color management profiles, select the DIOMANDCOMPATIDLEG2.2 scheme, click the "Set as Default" button, save and restart the computer, the problem is solved.

The reason for this problem is because Photoshop is a Mac based application, it will not only occupy a large memory space, and will be transplanted to the PC when the use of a small problem, such as photoshop5.x in the input characters garbled problems and so on. In this case, there is a conflict between the monitor-specific driver and the color management of Photoshop.
