For example, when a new display screen is introduced, the collocation of the display screen and the system needs to be verified, and when the display screen has abnormal pictures such as horizontal stripes, flicker, and the like, the display configuration information needs to be modified by the TV board card for experimental comparison.
For another example, when there is frequency interference between an OC and a Twisted Pair (TP) to cause TP abnormal operation, a TV board needs to modify display configuration information to clarify the correlation, but in the prior art, the TV board cannot modify the display configuration information, so that it is difficult to clarify the correlation, which may result in that the problem cannot be solved in time.
For another example, in some cases, the display configuration information needs to be modified to optimize the screen display effect, but since the TV board card in the prior art cannot modify the display configuration information, it is not possible to modify the display configuration information to improve the image quality.
In consideration of the problem that the problem solving effect under some scenes is affected due to the fact that the TV board card cannot acquire and modify the display configuration in the prior art, the TV board card is connected with the data storage of the OC drive system, so that the TV board card can acquire the display configuration information from the data storage and modify the display configuration information, and the problem under some scenes is solved quickly.
