Monitor standby status blue screen failure

Q: I have a benq LCD, the previous use of the VGA interface, everything is normal, now use the HDMI interface, Shutdown prompts the HDMI interface is not connected, and then the blue screen, but the host has been normal shutdown. Excuse me, why is this?

A: The blue screen you are talking about is not the system blue screen as it is usually called. Some liquid crystal display in the use of HDMI interface, if the detection of no input signal will display a blue screen, rather than the usual black screen and enter the energy-saving mode, such as standby, shutdown state, or even the system screen and game screen switching moment will have this situation. This is not a fault. Some brands of products can be used to brush the firmware to solve this problem, I suggest you and the manufacturer customer service to see if there is a solution, if not only after each shutdown manually cut the monitor power.
