@idk104, Welcome to HP Support Community,

Thank you for posting your query; I’m here to help by guiding you through steps to resolve this issue

It seems like you're experiencing an issue with your HP All-in-One Desktop PC's display being black. Here are some troubleshooting steps you can try to resolve the problem:

Check Power Connection:

• Ensure the computer is properly plugged into a power outlet and the power cable is securely connected.

Restart Your PC:

• Perform a hard reset by holding down the power button until the computer turns off, then turn it back on.

Display Brightness:

• Use the brightness controls on the side or bottom of the monitor (if available) to ensure the brightness is not set to zero or very low.

External Monitor Test:

• If possible, connect your All-in-One PC to an external monitor using an HDMI cable to see if the issue is with the internal display.

Check Cable Connections:

• Ensure that all cables connecting the display to the motherboard are properly seated and have not come loose.

Update Drivers:

• Access HP’s website and ensure that the latest display drivers are installed for your model.

Perform a Hard Reset:

• Disconnect the AC power, wait a few seconds, reconnect the power, and attempt to restart the computer.

Also, I suggest you refer to this guide: HP PCs - Computer starts but the screen remains blank (Windows 11, 10) | HP® Support
