Troubleshooting steps for the “No Signal” problem

1: Checking the cable connections

The first step in troubleshooting the “No Signal” issue is to check the cable connections. Start by inspecting the cable connecting your computer to the Acer monitor. Ensure that it is securely plugged into both the computer’s video output port and the monitor’s input port. If the cable appears loose, try disconnecting and reconnecting it firmly.

Next, examine the cable itself for any signs of damage, such as frayed or bent pins. If you notice any physical damage, it’s best to replace the cable with a new one. Remember to use a cable that is compatible with your monitor and computer’s video output.

2: Adjusting the display settings on your computer

If the cable connections are all secure and undamaged, the next step is to check and adjust the display settings on your computer. Start by right-clicking on your desktop and selecting “Display Settings” from the context menu.

In the Display Settings window, check the resolution and refresh rate values. Ensure that they are set to values supported by your Acer monitor. If you’re unsure of the correct settings, consult your monitor’s user manual or visit Acer’s website for specifications.

Try changing the resolution and refresh rate to different values and see if the “No Signal” issue persists. If you find a combination that works, stick with it. If not, proceed to the next troubleshooting step.
