I have both the HDMI and DP cables hooked up to my Amzfast AMZG27F5 Pro monitor, but I keep getting a 'No Signal' message on the screen. It worked fine for the first month, but now it has trouble booting up. What should I do?

If your Amzfast AMZG27F5 Pro monitor is displaying a "No Signal" message despite cables being tightly connected, please try the following troubleshooting steps based on the user manual:Manually Select Input Source: The monitor may not be automatically detecting the active cable. Use the joystick or buttons on the monitor to open the On-Screen Display (OSD) Menu, navigate to Input Source, and manually select either DisplayPort or HDMI depending on which one you are currently trying to use.Test One Cable at a Time: Having both HDMI and DisplayPort cables connected simultaneously to the same PC can sometimes cause handshake issues during boot-up. Try disconnecting one cable and booting with only the DP or only the HDMI cable attached.Check Power Supply: Ensure the power adapter is firmly plugged into both the monitor's DC input and a working wall outlet. A failing power supply can sometimes cause the monitor to fail to initialize the video signal.Update Graphics Drivers: Since the issue started after a month of use, ensure your computer's graphics card drivers are up to date, as driver corruption can lead to signal detection failures.Try a Different Port/Cable: If possible, test with a different HDMI or DP cable to rule out a cable failure that may have developed over time.If the monitor continues to show a "No Signal" message or a grey screen after these steps, it may indicate a hardware defect. The AMZG27F5 Pro comes with a 1-year warranty; you should contact Amzfast customer support for further technical assistance or a warranty claim.
