If you have a Lenovo computer and an Acer ET221Q monitor, and you're experiencing issues with the monitor not displaying anything, even though the backlight is on, you're not alone. This article will provide a detailed guide on how to troubleshoot and resolve this issue.

1. Check Connections

The first step in troubleshooting a monitor that's not displaying anything is to check the connections. Make sure that the monitor is securely connected to the computer and that the cables are not damaged. Here are the steps to follow:

1. Turn off both the monitor and the computer.
2. Unplug the VGA or HDMI cable from the computer and the monitor.
3. Inspect the cable for any damage, such as cuts or bent pins.
4. Plug the cable back into the computer and the monitor.
5. Turn on the computer and the monitor.

2. Check Display Settings

If the connections are secure and not damaged, the next step is to check the display settings on the computer. Here are the steps to follow:

1. Right-click on the desktop and select Display settings.
2. Make sure that the Acer ET221Q monitor is detected and selected as the display.
3. Check the resolution and refresh rate. Make sure that they are set to the monitor's recommended settings.
4. Check the Multiple displays option. Make sure that it is set to Duplicate these displays or Extend these displays.

3. Update Display Drivers

If the display settings are correct, the next step is to update the display drivers. Here are the steps to follow:

1. Right-click on the Start button and select Device Manager.
2. Expand the Display adapters category.
3. Right-click on the display adapter and select Update driver.
4. Select Search automatically for updated driver software and follow the prompts to install the updates.

4. Reset BIOS Settings

If updating the display drivers doesn't resolve the issue, the next step is to reset the BIOS settings. Here are the steps to follow:

1. Turn off the computer and unplug the power cord.
2. Press and hold the power button for 10-15 seconds to drain any residual power.
3. Plug the power cord back into the computer.
4. Press the F2 key while the computer is booting up to enter the BIOS setup.
5. Navigate to the Save & Exit tab and select Load Defaults or Reset to Setup Defaults.
6. Save the changes and exit the BIOS setup.

5. Check the Monitor

If resetting the BIOS settings doesn't resolve the issue, the next step is to check the monitor itself. Here are the steps to follow:

1. Unplug the power cord from the monitor.
2. Wait for 30 seconds and then plug the power cord back into the monitor.
3. Check the monitor's input source. Make sure that it is set to the correct input (VGA or HDMI).
