There are many reasons why the monitor has no signal and the host is normal. The following are some possible reasons:

• No signal input: One of the most common reasons One is that the host does not output a signal to the display. This may be because the console does not power on, enter standby mode, hibernate mode, or sleep mode. Check that the host starts correctly and is running normally. If the host does not start, you can try restarting the host and check the connection.

• Signal cable connection problem: Another common reason why the monitor has no signal is that the signal cable is not connected correctly or is loosely connected.
