Hi @Vernonjunior,

Welcome to HP Support Community.

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

If your HP monitor screen is red upon boot-up, it might be due to several potential causes. Here are some troubleshooting steps to help resolve the issue.

Check the Cable Connections:

• Ensure that the HDMI, DisplayPort, or VGA cable connecting the monitor to the PC is securely attached on both ends.
• Try using a different cable to rule out a faulty cable.
• If possible, test with another monitor or device to check if the issue persists.

Adjust the Monitor Settings:

• Sometimes the color settings on the monitor can be inadvertently altered. Access the monitor's on-screen display (OSD) menu and reset the settings to default.
• If the monitor has color presets, switch between them to see if it affects the red tint.

Test the Graphics Card:

• If you have a dedicated graphics card, make sure it's properly seated in the PCIe slot.
• Try switching to the onboard graphics (if available) to see if the issue is related to the graphics card.
• You could also try the monitor on another PC to verify whether the issue is with the monitor or the PC.

Update Graphics Drivers:

• Outdated or corrupted graphics drivers can cause display issues. Ensure your GPU drivers are up-to-date by visiting the GPU manufacturer's website (NVIDIA, AMD, or Intel) and downloading the latest version.

Check for Hardware Issues:

• If the monitor still shows a red screen after trying the above steps, there may be a hardware issue with either the monitor or the graphics card.
• If possible, test your monitor with another PC to confirm if the monitor is faulty.

I hope this helps.

Take care and have a good day.
