The power LED light is on but there is no screen image
1. Check if the operating system had entered sleep or power-save mode. Press the joystick or move the mouse to wake it up.
2. Check if the signal cable (HDMI/DisplayPort/Type-C) is well connected, and confirm another end of the output cable has been firmly connected to the computer input port (graphics card). Unplug and plug 2-terminals again to ensure all pins aren't bent.
3. Replace the signal cable (HDMI/DisplayPort/Type-C) to take a cross-test
4. Check MENU ---> Input Source, and switch to the correct source.
5. Connect the monitor to the other computers (PC/Notebook) to confirm whether it is normal
