Under 3 connected to the keyboard, percussion keyboard, screen is back to normal, according to
4 when a black screen, unplug the monitor power, then plug in the monitor power supply, the display will show "no signal no signal", in a few seconds after getting all black screen,
According to these phenomena, basic can inference is a host without display video signal output, is host to close off the display output, it concluded that correct?
