A blacked-out Acer KG251Q P3 monitor could be due to several issues, but the most common are connection problems, driver issues, or power supply problems. First, try checking the basic connections and cycling the power on both the monitor and the computer. If that doesn't work, try different ports on both the monitor and the computer, and consider testing with another device. If the problem persists, you may need to update or reinstall your graphics drivers, or even try booting into safe mode to troubleshoot further.

Here's a more detailed breakdown of troubleshooting steps:
1. Check the Basics:
Power:
Ensure the monitor is properly plugged into a working power outlet and that the power switch on the monitor is turned on.
Connections:
Verify that the video cable (HDMI or DisplayPort) is securely connected to both the monitor and the computer.
Input Source:
Check that the monitor's input source is set correctly (e.g., HDMI1, HDMI2, DisplayPort) to match the port your computer is connected to.
2. Cycle Power:
Monitor: Turn off the monitor completely, unplug it from the power outlet, wait a few seconds, and then plug it back in and turn it on.
Computer: Similarly, power cycle your computer by shutting it down, unplugging it, waiting, and then powering it back on.
3. Try Different Ports: Monitor:
If you have multiple HDMI or DisplayPort inputs on the monitor, try connecting to a different one.
Computer: If possible, try connecting the monitor to a different video output port on your computer (e.g., a different HDMI port or a DisplayPort).
