HI @JJ_Lee,

Welcome to HP Support Community.

Thank you for posting your query, I will be glad to help you.

It sounds like your monitor might be experiencing hardware issues or there's a problem with the graphics card or its connection. Here are some steps you can take to troubleshoot and potentially resolve the issue:

1. Check the Connections

• Solution: Ensure that all cables connecting the monitor to the computer are securely plugged in.
• Steps: Disconnect and reconnect the video cable (HDMI, DisplayPort, DVI, or VGA). Also, check for any bent pins if you're using a DVI or VGA cable.

2. Try a Different Cable

• Solution: The cable might be faulty.
• Steps: Replace the current video cable with a different one to see if the issue persists.

3. Test with Another Monitor

• Solution: Determine if the problem is with the monitor or the computer.
• Steps: Connect your computer to another monitor. If the issue does not occur on the other monitor, then the problem likely lies with the original monitor.

4. Test with Another Device

• Solution: Determine if the problem is with the computer or the monitor.
• Steps: Connect another device (like a laptop or another desktop) to the monitor. If the problem persists, the issue is with the monitor.

5. Check Graphics Card

• Solution: The graphics card might be loose or failing.
• Steps: If you have a desktop, open the case and ensure the graphics card is properly seated in its slot. If possible, test the graphics card in another computer or test a different graphics card in your computer.

6. Update Graphics Drivers

• Solution: The issue might be related to outdated or corrupted drivers.
• Steps:
  1. Boot your computer into Safe Mode (if possible) or use another monitor.
  2. Go to the graphics card manufacturer's website (NVIDIA, AMD, Intel) and download the latest drivers.
  3. Install the updated drivers and restart your computer.

7. Check Monitor Settings

• Solution: The monitor settings might have been inadvertently changed.
• Steps: Use the monitor's built-in menu (usually accessed via buttons on the monitor) to reset it to factory settings.

8. Test for Overheating

• Solution: Overheating components can cause display issues.
• Steps: Ensure your computer and monitor are well-ventilated. Clean any dust from vents and fans. Use software to monitor GPU and CPU temperatures.

9. Check for Interference

• Solution: Electromagnetic interference from other devices can cause display issues.
• Steps: Move other electronic devices away from the monitor to see if the issue resolves.

10. Hardware Diagnostics

• Solution: Use built-in or third-party tools to diagnose hardware issues.
• Steps: Run built-in diagnostics (available in BIOS/UEFI for some systems) or use tools like HWMonitor, GPU-Z, or memtest86 to check for hardware faults.

I hope this helps.

Take care and have a good day.
