Hi,

Thanks for the update and response.

I suggest you to reinstall the monitor drivers form the manufacturer website and check if it helps. Follow the below steps for the same.

• Press “Windows Logo” + “X” keys on the keyboard.
• Click on “Device Manager” from that list.
• Search for the Monitor driver from the device list, right click on it and then select “Uninstall”. On the un-installation window, if you have an option: “Delete the driver software for this device” you may select that
  and then remove the corrupted drivers from the computer.
• Follow the on-screen instructions to complete it and then restart the computer if prompted.

Refer the below link for the same.

No display on laptop's external monitor-Monitor recognized but blank

After the recent Windows 10 update, my wife's laptop no longer displays on the external monitor. All was well before the update.

I am comfortable that Windows sees the monitor because clicking on Display Settings shows two displays. If I unplug the HDMI cable, only one display is shown.

I have confirmed that the monitor works by trying it with another laptop. I have also changed the HDMI cable between the laptop and the external monitor.

Device manager reports that I have the latest display driver installed.

I would appreciate any and all suggestions.
