We got a good deal on some Acer monitors for the whole office so that everyone could have two monitors. Shortly after they got installed we would run into issues where only one monitor would come on. These were put into the Display Ports. The monitor would show “No Signal” even with the blue power light glowing.
This was the best fix for us.
- Unplug the power cord from the “no signal” monitor
- Restart the computer
- Make sure the monitor is powered back up before the computer starts back up..
Let us know if this helped you…
