Video signal sometimes flash screen (paperless conference system) failure Cause: Most of the lines are too long, (liquid crystal screen lifter) wire quality itself has problems, the matrix is not compatible with the interface of other manufacturers when the interface is not compatible;
Processing method:
v Check if the interface of the cable is loose, and re-plug it after power off (ultra-thin one lifter)
v Check how long the signal line is, possibly because the signal line is too long and the signal attenuation is too large;
v The signal source does not correspond to the resolution of the display device, which may also cause a splash screen. (LCD flip-flop) adjusts the signal source resolution
v Strong electrical interference (microphone lifter)
v If it is a splash screen during docking, you can directly connect the output of the matrix to the display device to see if it is normal (paperless office system);
