① Unable to play video solution

Status: The notebook is a Windows system, after connecting the projector with WMP, Realpaler and Jinshan shadow PA play a video file, notebook normal display, but when projected out, the video frame is a black, no image.

Cause: The result of a mismatch between the display properties and the projector's performance

Solution One: Modify: Display Properties-Settings-advanced-performance-hardware acceleration

The hardware acceleration adjustment must not can easily solve the TV back projection and projector video file playback problems, the general tune two-grid on the line, adjusted to affect the performance of the computer.

② Projector display resolution is not correct

Symptoms: 1. Screen picture display is incomplete, or up or down or around, there are always some places show incomplete;

2. Open the opportunity to display the progress bar and start screen, and then do not display.

Solution: Modify the notebook resolution, such as change to 800*600 or lower, do not use widescreen resolution, and so on.

③ projector cannot be displayed or not fully displayed

Symptoms: In ensuring that the projector's power cable, data signal lines and other connections are correct, the projector's light bulb and cooling fan is also working normally, but no computer screen projection. Or sometimes the projection screen is not completely displayed.

Reason: Because the projector bulb and cooling fan can operate normally, eliminate the possibility of projector failure, and the computer can be used normally, so also eliminate the possibility of computer failure. The problem, then, may be the signal cable or the projector and the computer's setup.

Solution: Most projector users are connected using a laptop computer, then can not be projected to the external video port of the notebook is not activated, just press and hold the notebook's FN key, and then press the corresponding function keys identified as LCD/CRT or monitor icon, to switch. When the switch is still unable to display the time, may be the problem of the computer input resolution, at this time as long as the computer's display resolution and refresh rate adjustment to the scope allowed by the projector, but also need to pay attention to the projector screen aspect ratio setting.

There is also a situation, when connected to the projector, you right-click on the computer desktop-Properties-settings, below a look like a small box to put the screen into the external device to play small √ on the line as shown

Note: Sometimes the projection screen although can display, but only show a part of the computer image, this may be the computer output resolution is too high, can properly reduce the computer resolution and then projection. If the problem after the above treatment is still, it is possible that LCD projector LCD panel has been damaged or DLP projector in the DMD chip has been damaged, then need to be sent to professional maintenance.

To sum up is a number of common problems and solutions, if encountered, there is no way to solve, then give the computer from a system, I test the machine is Asus PEN, found that there is an ATI graphics card driver to damage, online also said a lot of methods, are pressed to do, but is not good, Helpless under the system after doing everything is normal, may be in the process of the calculation of the use of some files lost, but do not know which file is missing, from making a system is the best choice.
