3. Incomplete display file or incorrect position

A: First check whether the parameters of "display position" and "screen size" in the software are consistent with those given in the installation project. If you don't remember, you can count the number of pixels in the length and width on the screen. After the "screen size" is determined, you can see how much difference is displayed on the screen, and then go back to the computer and adjust it until the position is consistent.

B: In case of incomplete display, check if the file size is the same as the “screen size” of the screen.

C: Open the case and check if the conductor is dropped on the control card.
