🖥️ PC Screen Suddenly Blank? Here's What to Do When the Display Is Gone

Written By m byrne

If your PC turns on but the screen stays black, don’t panic. Whether you're working, gaming, or just browsing, a missing display can be frustrating—but it doesn’t always mean your computer is dead.

Here are some quick tips to help diagnose and solve the issue:

🔌 Step 1: Check the Basics

  • Power cable – Is the monitor plugged in and turned on?

  • Cable connections – Ensure the HDMI, VGA, or DisplayPort cables are securely connected to both the monitor and the PC.

  • Monitor input – Make sure it’s set to the correct source (HDMI1, HDMI2, etc.).

🧠 Step 2: Test the Monitor

  • Try connecting the monitor to another PC or laptop to see if it works.

  • If it does, your PC graphics card or cable may be the issue.

⚙️ Step 3: Reboot and Listen

  • Restart your PC and listen for beeps or fans—this can indicate it’s running.

  • If it boots up and you hear Windows sounds, your display is the likely culprit.

🛠️ Step 4: Try Safe Mode or External Display

  • Connect to an external monitor or TV to check if it's a screen-only issue.

  • Try booting into Safe Mode to diagnose graphics driver issues.
