Confirm and Cycle Input Sources
If the monitor works with a different device, the problem may lie with the computer. Check the cable connections between the computer and the monitor. Make sure the cables are securely plugged in and not damaged. Also, check the display resolution settings on the computer to ensure they are compatible with the monitor.
If the issue persists, try restarting the computer. Sometimes, a simple reboot can resolve connectivity issues between the computer and the monitor. Additionally, check the power-saving settings on the computer to ensure it is not in hibernation mode.
By confirming and cycling through input sources, you can troubleshoot and resolve the “No Signal” issue with your Acer monitor efficiently.

Inspect for Hardware and Graphics Card Issues
Inspect the hardware connections on your Acer monitor to ensure that all cables are securely plugged in. Check the power cable, video cable, and any other connections that may be loose or disconnected.
Look for any visible damage or wear on the cables or ports. If you notice any issues, consider replacing the cables to see if that resolves the “No Signal” problem on your monitor.
Next, check the graphics card in your computer to make sure it is properly seated in the slot. If you have a dedicated graphics card, try reseating it to ensure a proper connection.
If you are using a laptop, consider updating the drivers for the graphics card. Sometimes outdated drivers can cause issues with the display on external monitors.
If you have a desktop computer, you may also want to check the display resolution settings in your operating system. Make sure the resolution is set to a compatible setting for your Acer monitor.
By inspecting for hardware and graphics card issues, you can troubleshoot and potentially fix the “No Signal” problem on your Acer monitor.
