No signal from the display:

1.The host is not booting properly, so there is no output.

2.The signal line of the display is loose.

3.The monitor is damaged.

The display screen is "black" and the power indicator is not lit, and most of these faults are the fault of the display itself. First of all, check whether the power cord of the monitor is properly connected, whether the power plug is in good contact with the 220V AC socket, and whether the power switch of the monitor is turned on. After confirming that the 220V AC power is properly delivered to the inside of the monitor, it can be judged that the display is faulty.

Fault phenomena such as the "black screen" of the display and the light of the power indicator are more complicated to locate, and the fault may occur in the display, graphics card, motherboard, or signal cable.
