💻 Computer Black Screen Troubleshooting Log
My desktop computer is always kept on. Usually, I only turn off the monitor when I leave or don’t use it at night.
🚨 Problem Description After a routine operation, I discovered that the display was consistently in a black screen state. Attempting to power cycle the monitor, the screen still displayed “No Signal Input”. Using UU Remote Control to view the status, I found that both the desktop PC and another mini host were showing as online, indicating that the host itself may not have been shut down.
