|Hi Robel, start by proving the monitor is ok.|
Take it AND its interface cable and try on another pc.
The monitor is probably ok as it displays the message, but this will prove also the cable.
Alternatively, check the interface cable is connected to the correct socket.
e.g. sometimes the mobo has a monitor socket, which does not work when a Graphics Card has been installed.
Good Luck - Keep us posted.
