The Elitebook 1040 G4’s monitor will not display, or flickers on and off even when you are sure the power is on.
Wake up the monitor by briefly pressing the power button or using the keys Windows Button+CTRL+Shift+B.
Disconnect the external monitor to see if the built in monitor display is restored. If you are sure the external monitor is compatible with your Elitebook 1040 G4, reconnect the external monitor and ensure the cable is properly inserted and not loose.
An unexpected black screen error can periodically occur with Windows 10 installed. Restart your Elitebook 1040 G4 and boot in Safe Mode.
Check to see if the Task Manager window is also flickering by using the keys CTRL+Shift+ESC. If the Task Manager window flickers with the screen, the display drivers must be updated or reinstalled.

The screen on the Elitebook 1040 G4 is suffering from green, red, or black dots.
Use an external program such as UDPixel to flash the pixel to restore its proper function. If flashing it does not fix the problem, try using a soft cloth or rubber eraser to manually rub the pixel. If neither techniques work, or the pixel is black, the monitor may need to be replaced. Refer to your Elitebook 1040 G4’s warranty for a potential replacement.
The Elitebook 1040 G4s fan is running faster than usual and is spinning loudly.
