On the 92" Touchscreen Max, lines may appear on the screen. This issue is caused by a software problem in the screen that only occurs on the 92" screens.
The cause lies in a communication error between the docking board and the TCON of the screen, which can cause this problem to occur sporadically. We are working on a solution that we expect to share before 22 May.
The current solution is to disconnect the power from the screen once and restart the screen.
