Second display started to experience errors

Because Notepad menus and Word hover effects are both affected only on the second display, the display path is worth checking before doing more application repairs. That pattern alone does not identify the RTX driver, monitor, or cable as the cause.

Move the same Notepad window between screens and confirm whether the corruption follows the window or the monitor. In Settings > System > Display, select the external monitor and use its Recommended resolution and scale as a baseline. Then test a direct connection without a dock or adapter, replace the display cable, and try the monitor with another computer.

You can also press Windows+Ctrl+Shift+B to reset the graphics driver. Since Windows Update is already current, record the installed graphics-driver versions and check the laptop manufacturer’s compatible updates. If it persists, submit Feedback Hub reproduction details, including the exact Windows build and connection type.
