Check the Input Source

Acer monitor no signal may be caused by the incorrect input source. Most monitors have multiple available input sources including DP, VGA, HDMI, and DVI so that you can connect multiple devices like a PC and a game console to the same monitor. You can use the firmware menu of the display to switch between each other.

To fix the no signal issue, you should make sure the input source is correct.

  1. Turn on your computer and monitor.
  2. Press the menu button on the edge of the display.
  3. Go to Input Source and choose a proper one. For instance, you should set the input source as HDMI if you connect your monitor to the HDMI port on your computer.

Check the Cable

This is a simple way to fix Acer monitor not getting signal. If there is a loose connection between your monitor and computer, the issue will appear. So, check whether your cable is firmly connected or not.

Besides, check if the cable is faulty. If it is damaged, replace the cable with a new one and see if the monitor can work.

Check if PC Is in Sleep

This is another way to detect the Acer monitor signal problem. If your computer is in sleep mode, it cannot receive any signals. Just press any key on the keyboard and see if the PC wakes up. Also, you can move the mouse to wake up your computer.
