@TheBeesx2, Welcome to HP Support Community,

Thank you for posting your query; I’m here to help by guiding you through steps to resolve this issue

If your HP Notebook 15-dy1076nr's screen turns to greyscale after logging in, but displays full color prior to entering your password, it likely involves a change in display settings after login. Here are steps you can take to troubleshoot and resolve the issue:

Check Color Filters:

• Press Windows + I to open Settings.
• Navigate to Ease of Access > Color & high contrast.
• Ensure that Color filters are turned off.

Display Settings:

• Right-click an empty space on your desktop and select Display settings.
• Scroll down and select Advanced display settings.
• Make sure the color settings are appropriately configured.

Graphics Driver Update:

• Open Device Manager by pressing Windows + X and selecting it from the list. Expand Display adapters.
• Right-click and select Update driver for your graphics card.

Advanced Settings in Graphics Control Panel:

• Sometimes, specific graphics card settings can enforce greyscale. Access these settings via:
  • For Intel: Right-click on the desktop and select Graphics Properties.
  • For NVIDIA: Right-click on the desktop and select NVIDIA Control Panel.
  • For AMD: Right-click on the desktop and select AMD Radeon Settings.

System Restore:

• If recent changes are causing the issue, you can perform a system restore:
  • Type System Restore into the Windows search bar and select Create a restore point.
  • Click System Restore and follow the prompts to restore your computer to a previous state.
