Hi Welcome to Microsoft community. Given your system specs and the issue you're facing, it seems you have a powerful setup that should easily handle multiple monitors. The problem you're encountering with moving windows across screens using the Windows logo key + Shift + ← / → might be due to a few different factors. Here are some troubleshooting steps to consider: 1. Update NVIDIA DriversOutdated or corrupted graphics drivers can cause issues with multi-monitor setups.
- Visit the official NVIDIA website to download and install the latest drivers for your RTX 3080 Ti.
- Alternatively, use the NVIDIA GeForce Experience app to check and update your drivers.
2. Monitor ConfigurationEnsure that your monitors are correctly configured and recognized by Windows.
- Right-click on the desktop and select Display settings.
- Verify that all your monitors are detected and arranged according to your physical setup.
- You might need to adjust the orientation or the order of the displays for the shortcuts to work as expected.
3. Keyboard Shortcut ConflictThere could be a software running in the background that's interfering with the Windows + Shift + Arrow keys shortcut.
- Check if any running applications have assigned the same keyboard shortcuts. This can often happen with gaming software or other utilities that allow for custom shortcuts.
4. Hardware Acceleration FeaturesSome applications, especially those that require high graphical processing, might not move between screens smoothly due to hardware acceleration features.
- Try disabling hardware acceleration in the applications that won't move across screens to see if that resolves the issue.
5. Windows Snap SettingsWindows Snap might interfere with moving windows across monitors in some setups.
- Go to Settings > System > Multitasking and play around with the Snap windows settings to see if disabling or adjusting them makes a difference.
6. Third-party Software Consider using third-party software designed to manage multi-monitor setups. You can do your own research on the web for reputable software. 7. Reinstall Graphics DriversTry completely uninstalling and then reinstalling your NVIDIA graphics drivers. Use the Display Driver Uninstaller (DDU) tool to remove all remnants of the previous drivers before installing the new ones.Let me know if you need further assistance.Best regardsDerrick Qian | Microsoft Community Support Specialist
