Hi @Rohan0071,

Welcome to the HP Support Community.
 

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

Since this is happening on your HP Desktop PC and not a printer, and you're seeing a red light or glow on both sides of the screen when dark content is displayed, this sounds like a monitor or GPU-related issue. Let’s explore how to fix it.

Steps to Troubleshoot the Red Glow

1. Check Monitor Settings

• Use the monitor’s physical buttons to open the OSD menu.
• Look for: 
  • Color Temperature (set to Standard or 6500K)
  • Gaming/Visual Modes (disable any special modes)
  • Reset to Factory Defaults

2. Update Graphics Drivers

• Open Device Manager > Display Adapters.
• Right-click your GPU (Intel, AMD, or NVIDIA) and select Update driver.
• Or download the latest driver from the manufacturer’s site: 
  • Intel
  • AMD
  • NVIDIA

3. Try a Different Cable or Port

• Swap your HDMI/DisplayPort cable.
• Try a different port on the GPU or monitor.
• If possible, test the monitor with another PC or laptop.

4. Run Display Diagnostics

• If it’s an HP monitor, you can run HP PC Hardware Diagnostics: 
  • Press Esc at startup → Select F2 for diagnostics → Run Display Test.

I hope this helps.

Take care and have an amazing day!
