Hello Thank you for posting in our Q&A forum. The built-in function of Windows 10 supports the split-screen method of two-split screen/three-split screen/four-split screen. The shortcut is:
- Click the current program and press Win + ←/→ at the same time to shrink the application window to half and adjust the left and right positions.
- On the basis of the previous step, press and hold Win + ↑/↓ at the same time to realize the quarter window display in the upper right corner.
In addition, you can also use third-party split screen tools to meet your needs. Hope above information can help you.
